DOSAGE AND ADMINISTRATION
Prior to treating patients with ADZENYS ER, assess for the presence of cardiac disease (i.e., perform a careful history, family history of sudden death or ventricular arrhythmia, and physical exam) [see WARNINGS AND PRECAUTIONS].
Assess the risk of abuse prior to prescribing, and monitor for signs of abuse and dependence while on therapy. Maintain careful prescription records, educate patients about abuse, monitor for signs of abuse and overdose, and periodically re-evaluate the need for ADZENYS ER use [see WARNINGS AND PRECAUTIONS and Drug Abuse And Dependence].
Dosing Considerations For All Patients
dminister ADZENYS ER orally once daily in the morning with or without food. The dose should be individualized according to the therapeutic needs and response of the patient.
Shake the bottle of ADZENYS ER before administering the dose. Do not add ADZENYS ER to food or mix ADZENYS ER with other liquids before consuming.
he recommended starting dose for patients 6 to 17 years of age is 6.3 mg (5 mL) once daily in the morning. Increase in increments of 3.1 mg (2.5 mL) or 6.3 mg (5 mL) at weekly intervals. The maximum dose is 18.8 mg (15 mL) daily for patients 6 to 12 years, and 12.5 mg (10 mL) daily for patients 13 to 17 years.
The recommended dose of ADZENYS ER for adults is 12.5 mg (10 mL) daily.
Switching From Other Amphetamine Products
Patients taking ADDERALL XR may be switched to ADZENYS ER at the equivalent dose taken once daily [see CLINICAL PHARMACOLOGY]. Refer to Table 1 for equivalent doses of ADZENYS ER and ADDERALL XR. ADDERALL XR (dextroamphetamine sulfate, dextroamphetamine saccharate, amphetamine aspartate monohydrate, and amphetamine sulfate extended-release capsules) is also referred to as mixed salts of a single-entity amphetamine product extended-release capsules (MAS ER).
Table 1: Equivalent Doses of ADZENYS ER and ADDERALL XR (Mixed Salts of a Single-Entity Amphetamine Product) Extended-Release Capsules
|ADZENYS ER Amphetamine extended-release oral suspension||3.1 mg (2.5 mL)||6.3 mg (5 mL)||9.4 mg (7.5 mL)||12.5 mg (10 mL)||15.7 mg (12.5 mL)||18.8 mg (15 mL)|
|ADDERALL XR Mixed salts of a single-entity amphetamine product extended-release capsules (MAS ER)||5 mg||10 mg||15 mg||20 mg||25 mg||30 mg|
f switching from any other amphetamine products, discontinue that treatment, and titrate with ADZENYS ER using the titration schedule [see Pediatric Patients, Adults].
Do not substitute for other amphetamine products on a milligram-per-milligram basis because of different amphetamine salt compositions and differing pharmacokinetic profiles [see WARNINGS AND PRECAUTIONS].
Dosage Modifications Due To Drug Interactions
Agents that alter urinary pH can impact urinary excretion and alter blood levels of amphetamine. Acidifying agents (e.g., ascorbic acid) decrease blood levels, while alkalinizing agents (e.g., sodium bicarbonate) increase blood levels. Adjust ADZENYS ER dosage accordingly [see DRUG INTERACTIONS].
Dosage Forms And Strengths
Extended-release oral suspension contains 1.25 mg amphetamine per mL.
Storage And Handling
ADZENYS ER has a concentration of 1.25 mg per mL amphetamine and is supplied as a light orange to golden, viscous, opaque suspension with orange flavor in bottles of 450 mL (NDC 70165-003-15).
Dispense in a tight container with child-resistant closure.
Store at 20°C to 25°C (68°F to 77°F); excursions permitted from 15°C to 30°C (59°F to 86°F) [see USP Controlled Room Temperature].
The pharmacist should provide an oral dosing device or other suitable measuring device.
Comply with local laws and regulations on drug disposal of CNS stimulants. Dispose of remaining, unused, or expired ADZENYS ER at authorized collection sites such as retail pharmacies, hospital or clinic pharmacies, and law enforcement locations.

Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.
The safety of ADZENYS ER has been established from adequate and well-controlled studies of single-entity amphetamine product extended-release (MAS ER) capsules [see Clinical Studies]. The adverse reactions of MAS ER capsules in these adequate and well-controlled studies are described below.
The premarketing development program for MAS ER included exposures in a total of 1315 participants in clinical trials (635 pediatric patients, 350 adolescent patients, 248 adult patients, and 82 healthy adult subjects). Of these, 635 patients (ages 6 to 12) were evaluated in two controlled clinical studies, one open-label clinical study, and two single-dose clinical pharmacology studies (N= 40).
Adverse Reactions Leading To Discontinuation Of Treatment
The most frequent adverse reactions leading to discontinuation of MAS ER in controlled and uncontrolled, multiple-dose clinical trials of pediatric patients ages 6 to 12 years (N=595) were anorexia (loss of appetite) (2.9%), insomnia (1 5%), weight loss (1.2%), emotional lability (1%), and depression (0.7%).
In a separate placebo-controlled 4-week study in pediatric patients 13 to 17 years with ADHD, five patients (2.1%) discontinued treatment due to adverse events among MAS ER-treated patients (N=233) compared to none who received placebo (N=54). The most frequent adverse event leading to discontinuation and considered to be drug-related (i.e. leading to discontinuation in at least 1% of MAS ER-treated patients and at a rate at least twice that of placebo) was insomnia (1.3%, n=3).
In one placebo-controlled 4-week study among adults with ADHD with doses 20 mg to 60 mg, 23 patients (12.0%) discontinued treatment due to adverse events among MAS ER-treated patients (N=191) compared to one patient (1.6%) who received placebo (N=64). The most frequent adverse events leading to discontinuation and considered to be drug-related (i.e. leading to discontinuation in at least 1% of MAS ER-treated patients and at a rate at least twice that of placebo) were insomnia (5.2%, n=10), anxiety (2.1%, n=4), nervousness (1.6%, n=3), dry mouth (1.6%, n=3), anorexia (1.6%, n=3), tachycardia (1.6%, n=3), headache (1.6%, n=3), and asthenia (1.0%, n=2).
Adverse Reactions Occurring In Controlled Trials
Adverse reactions reported in a 3-week clinical trial of pediatric patients 6 to 12 years and a 4week clinical trial in pediatric patients 13 to 17 years of age and adults, respectively, treated with MAS ER or placebo are presented in the tables below.

Drugs Having Clinically Important Interactions With Amphetamines
Table 5: Drugs Having Clinically Important Interactions with Amphetamines
|MAO Inhibitors (MAOI)|
|Clinical Impact||MAOI antidepressants slow amphetamine metabolism, increasing amphetamines effect on the release of norepinephrine and other monoamines from adrenergic nerve endings causing headaches and other signs of hypertensive crisis. Toxic neurological effects and malignant hyperpyrexia can occur, sometimes with fatal results.|
|Intervention||Do not administer ADZENYS ER during or within 14 days following the administration of MAOI [see CONTRAINDICATIONS].|
|Examples||selegiline, isocarboxazid, phenelzine, tranylcypromine|
|Clinical Impact||The concomitant use of ADZENYS ER and serotonergic drugs increases the risk of serotonin syndrome.|
|Intervention||Initiate with lower doses and monitor patients for signs and symptoms of serotonin syndrome, particularly during ADZENYS ER initiation or dosage increase. If serotonin syndrome occurs, discontinue ADZENYS ER and the concomitant serotonergic drug(s) [see WARNINGS AND PRECAUTIONS)].|
|Examples||selective serotonin reuptake inhibitors (SSRI), serotonin norepinephrine reuptake inhibitors (SNRI), triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, tryptophan, buspirone, St. John’s Wort|
|Clinical Impact||Increase blood levels and potentiate the action of amphetamine.|
|Intervention||Co-administration of ADZENYS ER and gastrointestinal alkalinizing agents should be avoided|
|Examples||Gastrointestinal alkalinizing agents (e.g., sodium bicarbonate). Urinary alkalinizing agents (e.g., acetazolamide, some thiazides).|
|Clinical Impact||Lower blood levels and efficacy of amphetamines.|
|Intervention||Increase dose based on clinical response.|
||Gastrointestinal acidifying agents (e.g., guanethidine, reserpine, glutamic acid HCl, ascorbic acid).|
|Clinical Impact||May enhance the activity of tricyclic or sympathomimetic agents causing striking and sustained increases in the concentration of d-amphetamine in the brain; cardiovascular effects can be potentiated.|
|Intervention||Monitor frequently and adjust or use alternative therapy based on clinical response.|
|Clinical Impact||May increase the exposure of amphetamine.|
|Intervention||Start with lower doses and monitor frequently and adjust ADZENYS ER dose or use alternative therapy based on clinical response.|
|Examples||paroxetine and fluoxetine (also serotonergic drugs), quinidine, ritonavir.|
|Gastric pH Modulators|
|Clinical Impact||May change the release profile, shape of pharmacokinetic profile and exposure to ADZENYS ER resulting in the potential for dose dumping.|
|Intervention||Concomitant use of ADZENYS ER with a gastric pH modulator (i.e. H2 blocker or proton pump inhibitor) is not recommended.|
|Examples||omeprazole, esomeprazole, pantoprazole, cimetidine|
Drug/Laboratory Test Interactions
Drug Abuse And Dependence
ADZENYS ER contains amphetamine, a Schedule II controlled substance in the U.S. Controlled Substances Act (CSA).
ADZENYS ER, is a CNS stimulant that contains amphetamine which has a high potential for abuse. Abuse is characterized by impaired control of drug use, compulsive use despite harm, and craving.
Signs and symptoms of amphetamine abuse may include increased heart rate, respiratory rate, blood pressure, and/or sweating, dilated pupils, hyperactivity, restlessness, insomnia, decreased appetite, loss of coordination, tremors, flushed skin, vomiting, and/or abdominal pain. Anxiety, psychosis, hostility, aggression, suicidal or homicidal ideation have also been observed. Abusers of amphetamines may use other unapproved routes of administration which can result in overdose and death [see OVERDOSE].
To reduce the abuse of ADZENYS ER, assess the risk of abuse prior to prescribing. After prescribing, keep careful prescription records, educate patients and their families about abuse and proper storage and disposal of CNS stimulants, monitor for signs of abuse while on therapy, and re-evaluate the need for ADZENYS ER use.
Tolerance (a state of adaptation in which exposure to a drug results in a reduction of the drug’s desired and/or undesired effects over time) may occur during the chronic therapy of CNS stimulants including ADZENYS ER.
Physical dependence (which is manifested by a withdrawal syndrome produced by abrupt cessation, rapid dose reduction, or administration of an antagonist) may occur in patients treated with CNS stimulants including ADZENYS ER. Withdrawal symptoms after abrupt cessation following prolonged high dosage administration of CNS stimulants include dysphoric mood; fatigue; vivid, unpleasant dreams; insomnia or hypersomnia; increased appetite; and psychomotor retardation or agitation.
Included as part of the "PRECAUTIONS" Section
Potential For Abuse Or Dependence
CNS stimulants, including ADZENYS ER, other amphetamine-containing products, and methylphenidate, have a high potential for abuse and dependence. Assess the risk of abuse prior to prescribing, and monitor for signs of abuse and dependence while on therapy [see BOX WARNING, Drug Abuse And Dependence].
Serious Cardiovascular Reactions
Sudden death, stroke, and myocardial infarction have been reported in adults with CNS stimulant treatment at recommended doses. Sudden death has been reported in children and adolescents with structural cardiac abnormalities and other serious heart problems taking CNS stimulants at recommended doses for ADHD. Avoid use in patients with known structural cardiac abnormalities, cardiomyopathy, serious heart arrhythmia, coronary artery disease, and other serious heart problems. Further evaluate patients who develop exertional chest pain, unexplained syncope, or arrhythmias during ADZENYS ER treatment.
Blood Pressure And Heart Rate Increases
Psychiatric Adverse Events
Exacerbation Of Pre-Existing Psychosis
CNS stimulants may exacerbate symptoms of behavior disturbance and thought disorder in patients with a pre-existing psychotic disorder.
Induction Of A Manic Episode In Patients With Bipolar Illness
CNS stimulants may induce a mixed or manic episode in patients with bipolar disorder. Prior to initiating treatment, screen patients for risk factors for developing a manic episode (e.g., comorbid or has a history of depressive symptoms or a family history of suicide, bipolar disorder, and depression).
New Psychotic Or Manic Symptoms
CNS stimulants, at recommended doses, may cause psychotic or manic symptoms (e.g., hallucinations, delusional thinking, or mania) in patients without prior history of psychotic illness or mania. If such symptoms occur, consider discontinuing ADZENYS ER. In a pooled analysis of multiple short-term, placebo-controlled studies of CNS stimulants, psychotic or manic symptoms occurred in 0.1% of CNS stimulant-treated patients compared to 0% in placebo-treated patients.
Long-Term Suppression Of Growth
CNS stimulants have been associated with weight loss and slowing of growth rate in pediatric patients. Closely monitor growth (weight and height) in pediatric patients treated with CNS stimulants, including ADZENYS ER.
Patients who are not growing or gaining height or weight as expected may need to have their treatment interrupted [see Use In Specific Populations].
Peripheral Vasculopathy, Including Raynaud’s Phenomenon
Stimulants, including ADZENYS ER, used to treat ADHD are associated with peripheral vasculopathy, including Raynaud’s phenomenon. Signs and symptoms are usually intermittent and mild; however, very rare sequelae include digital ulceration and/or soft tissue breakdown. Effects of peripheral vasculopathy, including Raynaud’s phenomenon, were observed in post-marketing reports at different times and at therapeutic doses in all age groups throughout the course of treatment. Signs and symptoms generally improve after reduction in dose or discontinuation of drug. Careful observation for digital changes is necessary during treatment with ADHD stimulants. Further clinical evaluation (e.g., rheumatology referral) may be appropriate for certain patients.
Serotonin syndrome, a potentially life-threatening reaction, may occur when amphetamines are used in combination with other drugs that affect the serotonergic neurotransmitter systems such as monoamine oxidase inhibitors (MAOIs), selective serotonin reuptake inhibitors (SSRIs), serotonin norepinephrine reuptake inhibitors (SNRIs), triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, tryptophan, buspirone, and St. John’s Wort [see DRUG INTERACTIONS]. The co-administration with cytochrome P450 2D6 (CYP2D6) inhibitors may also increase the risk with increased exposure to ADZENYS ER. In these situations, consider an alternative non-serotonergic drug or an alternative drug that does not inhibit CYP2D6 [see DRUG INTERACTIONS].
Serotonin syndrome symptoms may include mental status changes (e.g., agitation, hallucinations, delirium, and coma), autonomic instability (e.g., tachycardia, labile blood pressure, dizziness, diaphoresis, flushing, hyperthermia), neuromuscular symptoms (e.g., tremor, rigidity, myoclonus, hyperreflexia, incoordination), seizures, and/or gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea).
Discontinue treatment with ADZENYS ER and any concomitant serotonergic agents immediately if the above symptoms occur, and initiate supportive symptomatic treatment. If concomitant use of ADZENYS ER with other serotonergic drugs or CYP2D6 inhibitors is clinically warranted, initiate ADZENYS ER with lower doses, monitor patients for the emergence of serotonin syndrome during drug initiation or titration, and inform patients of the increased risk for serotonin syndrome.
Potential For Overdose Due To Medication Errors
Medication errors, including substitution and dispensing errors, between ADZENYS ER and other amphetamine products could occur, leading to possible overdosage. To avoid substitution errors and overdosage, do not substitute for other amphetamine products on a milligram-permilligram basis because of different amphetamine salt compositions and differing pharmacokinetic profiles [see DOSAGE AND ADMINISTRATION].
Potential For Intestinal Necrosis
Cases of intestinal necrosis, including some deaths, have been reported with the concomitant use of sodium polystyrene sulfonate and sorbitol, two of the inactive ingredients in ADZENYS ER. In these cases, patients were administered sodium polystyrene sulfonate to treat hyperkalemia at doses greater than 200 times the amount present in Adzenys ER. However, no absolute safe levels for the interaction of sodium polystyrene sulfonate and sorbitol have been established.
Patient Counseling Information
Advise the patient to read the FDA-approved patient labeling (Medication Guide).
Controlled Substance Status/Potential For Abuse, Misuse, And Dependence
Advise patients that ADZENYS ER is a federally controlled substance because it can be abused or lead to dependence. Advise patients to store ADZENYS ER in a safe place, preferably locked, to prevent abuse. Advise patients to comply with laws and regulations on drug disposal. Advise patients to dispose of remaining, unused, or expired ADZENYS ER by a medicine take-back program if available [see BOX WARNING, WARNINGS AND PRECAUTIONS , Drug Abuse And Dependence].
Dosage And Administration Instructions
Provide the following instructions on administration to the patient:
- Use with an oral dosing device or other suitable measuring device.
- Shake the bottle of ADZENYS ER before each dose.
- Measure the appropriate dose as prescribed by the physician.
- Use the filled oral dosing device or measuring device to dispense ADZENYS ER directly into mouth.
- Replace bottle cap and store bottle as directed.
- Wash oral dosing device or measuring device after each use.
Serious Cardiovascular Risks
Advise patients of serious cardiovascular risk (including sudden death, myocardial infarction, stroke, and hypertension) with ADZENYS ER. Instruct patients to contact a healthcare provider immediately if they develop symptoms such as exertional chest pain, unexplained syncope, or other symptoms suggestive of cardiac disease [see WARNINGS AND PRECAUTIONS].
Blood Pressure And Heart Rate Increases
Instruct patients that ADZENYS ER can cause elevations of their blood pressure and pulse rate and they should be monitored for such effects [see WARNINGS AND PRECAUTIONS].
Advise patients that ADZENYS ER at recommended doses, may cause psychotic or manic symptoms even in patients without prior history of psychotic symptoms or mania [see WARNINGS AND PRECAUTIONS].
Long-Term Suppression Of Growth
Advise patients, family members, and caregivers that ADZENYS ER may cause slowing of growth including weight loss [see WARNINGS AND PRECAUTIONS].
Circulation Problems In fingers And Toes [Peripheral Vasculopathy, Including Raynaud’s Phenomenon]
Instruct patients beginning treatment with ADZENYS ER about the risk of peripheral vasculopathy, including Raynaud’s phenomenon, and in associated signs and symptoms: fingers or toes may feel numb, cool, painful, and/or may change color from pale, to blue, to red.
Instruct patients to report to their physician any new numbness, pain, skin color change, or sensitivity to temperature in fingers or toes.
Instruct patients to call their physician immediately with any signs of unexplained wounds appearing on fingers or toes while taking ADZENYS ER.
Further clinical evaluation (e.g., rheumatology referral) may be appropriate for certain patients [see WARNINGS AND PRECAUTIONS].
Caution patients about the risk of serotonin syndrome with concomitant use of ADZENYS ER and other serotonergic drugs including SSRIs, SNRIs, triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, tryptophan, buspirone, St. John’s Wort, and with drugs that impair metabolism of serotonin (in particular MAOIs, both those intended to treat psychiatric disorders and also others such as linezolid [see CONTRAINDICATIONS, WARNINGS AND PRECAUTIONS and DRUG INTERACTIONS]. Advise patients to contact their healthcare provider or report to the emergency room if they experience signs or symptoms of serotonin syndrome.
Advise patients to notify their physicians if they are taking, or plan to take, any prescription or over-the-counter drugs because there is a potential for interactions [see DRUG INTERACTIONS].
Advise patients that there is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to ADZENYS ER during pregnancy [see Use In Specific Populations].
Advise patients to notify their healthcare provider if they become pregnant or intend to become pregnant during treatment with ADZENYS ER. Advise patients of the potential fetal effects from the use of ADZENYS ER during pregnancy [see Use In Specific Populations].
Advise patients not to breastfeed if they are taking ADZENYS ER [see Use In Specific Populations].
Advise patients to avoid alcohol while taking ADZENYS ER. Consumption of alcohol while taking ADZENYS ER may result in a more rapid release of the dose of amphetamine [see CLINICAL PHARMACOLOGY].
Carcinogenesis, Mutagenesis, Impairment Of Fertility
No evidence of carcinogenicity was found in studies in which d,l-amphetamine sulfate (enantiomer ratio of 1:1) was administered to mice and rats in the diet for 2 years at doses of up to 30 mg/kg/day in male mice, 19 mg/kg/day in female mice, and 5 mg/kg/day in male and female rats. These doses are approximately 3, 2, and 1 (equivalent) times, respectively, the maximum recommended human dose of 18.8 mg/day (as base) given to children on a mg/m2 basis.
Amphetamine, in the enantiomer ratio (d-to l-ratio of 3:1), was not clastogenic in the mouse bone marrow micronucleus test in vivo and was negative when tested in the E. coli component of the Ames test in vitro. d,l-Amphetamine (1:1 enantiomer ratio) has been reported to produce a positive response in the mouse bone marrow micronucleus test, an equivocal response in the Ames test, and negative responses in the in vitro sister chromatid exchange and chromosomal aberration assays.
Impairment Of Fertility
Amphetamine, in the enantiomer ratio d-to l-ratio of 3:1, did not adversely affect fertility or early embryonic development in the rat at doses of up to 20 mg/kg/day [approximately 12.4 times the maximum recommended human dose of 12.5 mg/day (as base) given to adolescents on a mg/m2 basis].
Use In Specific Populations
Pregnancy Exposure Registry
There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to ADZENYS ER during pregnancy. Healthcare providers are encouraged to register patients by calling the National Pregnancy Registry for Psychostimulants at 1-866-961-2388.
The limited available data from published literature and postmarketing reports on the use of prescription amphetamine in pregnant women are insufficient to inform a drug-associated risk for major congenital malformations or miscarriage. Adverse pregnancy outcomes, including premature delivery and low birth weight, have been seen in infants born to mothers dependent on amphetamines (see Clinical Considerations).
No effects on morphological development were observed in embryo-fetal development studies with oral administration of amphetamine to rats and rabbits during organogenesis at doses 4 and 20 times, respectively, the maximum recommended human dose (MRHD) of 12.5 mg/day (as base) given to adolescents, on a mg/m2 basis. However, in a pre-and post-natal development study, amphetamine (d-to l-ratio of 3:1) administered orally to pregnant rats during gestation and lactation caused a decrease in pup survival and a decrease in pup body weight that correlated with a delay in developmental landmarks at clinically relevant doses of amphetamine. In addition, adverse effects on reproductive performance were observed in pups whose mothers were treated with amphetamine. Long-term neurochemical and behavioral effects have also been reported in published animal developmental studies using clinically relevant doses of amphetamine (see Data).
The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.
Fetal/Neonatal adverse reactions
Amphetamines, such as ADZENYS ER, cause vasoconstriction and thereby may decrease placental perfusion. In addition, amphetamines can stimulate uterine contractions increasing the risk of premature delivery. Infants born to amphetamine dependent mothers have an increased risk of premature delivery and low birth weight.
Monitor infants born to mothers taking amphetamines for symptoms of withdrawal, such as feeding difficulties, irritability, agitation, and excessive drowsiness.
Amphetamine (d-to l-enantiomer ratio of 3:1) had no apparent effects on embryofetal morphological development or survival when administered orally to pregnant rats and rabbits throughout the period of organogenesis at doses of up to 6 and 16 mg/kg/day, respectively. These doses are approximately 4 and 20 times, respectively, the MRHD of 12.5 mg/day (as base) given to adolescents, on a mg/m2 basis. Fetal malformations and death have been reported in mice following parenteral administration of d-amphetamine doses of 50 mg/kg/day (approximately 15 times the MRHD given to adolescents on a mg/m2 basis) or greater to pregnant animals. Administration of these doses was also associated with severe maternal toxicity.
A study was conducted in which pregnant rats received daily oral doses of amphetamine (d-to lenantiomer ratio of 3:1) of 2, 6, and 10 mg/kg from gestation day 6 to lactation day 20. These doses are approximately 1, 4, and 6 times the MRHD of 12.5 mg/day (as base) given to adolescents, on a mg/m2 basis. All doses caused hyperactivity and decreased weight gain in the dams. A decrease in pup survival was seen at all doses. A decrease in pup body weight was seen at 6 and 10 mg/kg which correlated with delays in developmental landmarks, such as preputial separation and vaginal opening. Increased pup locomotor activity was seen at 10 mg/kg on day 22 postpartum but not at 5 weeks postweaning. When pups were tested for reproductive performance at maturation, gestational weight gain, number of implantations, and number of delivered pups were decreased in the group whose mothers had been given 10 mg/kg.
A number of studies in rodents indicate that prenatal or early postnatal exposure to amphetamine (d-or d, l-), at doses similar to those used clinically, can result in long-term neurochemical and behavioral alterations. Reported behavioral effects include learning and memory deficits, altered locomotor activity, and changes in sexual function.
Based on limited case reports in published literature, amphetamine (d-or d, l-) is present in human milk, at relative infant doses of 2% to 13.8% of the maternal weight-adjusted dosage and a milk/plasma ratio ranging between 1.9 and 7.5. There are no reports of adverse effects on the breastfed infant. Long term neurodevelopmental effects on infants from stimulant exposure are unknown. It is possible that large dosages of amphetamine might interfere with milk production, especially in women whose lactation is not well established. Because of the potential for serious adverse reactions in nursing infants, advise patients that breastfeeding is not recommended during treatment with ADZENYS ER.
Safety and effectiveness have been established in pediatric patients with ADHD ages 6 to 17 years of age in three adequate and well-controlled clinical trials of up to 4 weeks in duration [see ADVERSE REACTIONS , CLINICAL PHARMACOLOGY, Clinical Studies]. Safety and efficacy in pediatric patients younger than 6 years of age with ADHD have not been established.
Long-Term Growth Suppression
Growth should be monitored during treatment with stimulants, including ADZENYS ER, and children who are not growing or gaining weight as expected may need to have their treatment interrupted [see WARNINGS AND PRECAUTIONS].
Juvenile Animal Toxicity Data
Juvenile rats treated with mixed amphetamine salts early in the postnatal period through sexual maturation demonstrated transient changes in motor activity. Learning and memory was impaired at approximately 10 times the maximum recommended human dose (MRHD) given to children on a mg/m2 basis. No recovery was seen following a drug free period. A delay in sexual maturation was observed at a dose approximately 10 times the MRHD given to pediatric patients on a mg/m2 basis, although there was no effect on fertility.
In a juvenile developmental study, rats received daily oral doses of amphetamine (d to l enantiomer ratio of 3:1) of 2, 6, or 20 mg/kg on days 7-13 of age; from day 14 to approximately day 60 of age these doses were given twice daily for total daily doses of 4, 12, or 40 mg/kg. The latter doses are approximately 1, 3, and 10 times the MRHD of 18.8 mg/day (as base) given to children on a mg/m2 basis. Post-dosing hyperactivity was seen at all doses; motor activity measured prior to the daily dose was decreased during the dosing period but the decreased motor activity was largely absent after an 18 day drug-free recovery period. Performance in the Morris water maze test for learning and memory was impaired at the 40 mg/kg dose, and sporadically at the lower doses, when measured prior to the daily dose during the treatment period; no recovery was seen after a 19 day drug-free period. A delay in the developmental milestones of vaginal opening and preputial separation was seen at 40 mg/kg but there was no effect on fertility.
Clinical studies of ADZENYS ER did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should start at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
Consult with a Certified Poison Control Center (1-800-222-1222) for up-to-date guidance and advice for treatment of overdosage. Individual patient response to amphetamines varies widely. Toxic symptoms may occur idiosyncratically at low doses.
Manifestations of amphetamine overdose include restlessness, tremor, hyperreflexia, rapid respiration, confusion, assaultiveness, hallucinations, panic states, hyperpyrexia and rhabdomyolysis. Fatigue and depression usually follow the central nervous system stimulation. Other reactions include arrhythmias, hypertension or hypotension, circulatory collapse, nausea, vomiting, diarrhea, and abdominal cramps. Fatal poisoning is usually preceded by convulsions and coma.
DZENYS ER is contraindicated:
- In patients known to be hypersensitive to amphetamine, or other components of ADZENYS ER. Hypersensitivity reactions such as angioedema and anaphylactic reactions have been reported in patients treated with other amphetamine products [see ADVERSE REACTIONS].
- In patients taking monoamine oxidase inhibitors (MAOIs), or within 14 days of stopping MAOIs (including MAOIs such as linezolid or intravenous methylene blue), because of an increased risk of hypertensive crisis [see WARNINGS AND PRECAUTIONS and DRUG INTERACTIONS].
Mechanism Of Action
Pharmacokinetic studies of d-and l-amphetamine after oral administration of ADZENYS ER have been conducted in healthy adults (20 to 70 years) and pediatric patients (6 to 12 years) with ADHD. The mean (±SD) elimination half-life for d-amphetamine is 11.4 (2.3) hours in adults and 12.7 (6.4) hours in pediatric patients aged 6 to 12 years. For l-amphetamine, the mean (±SD) elimination half-life in adults is 14.1 (3.5) hours and 15.3 (14.4) hours in pediatric patients aged 6 to 12 years.
Following a single, 18.8 mg oral dose of ADZENYS ER in 42 healthy adult subjects in a crossover study under fasting conditions, d-amphetamine mean (±SD) peak plasma concentrations of 47.2 (±7.7) ng/mL occurred at a median (range) time of 5.0 (3, 7.5) hours after dosing, and l-amphetamine mean (±SD) peak plasma concentrations of 14.9 (±2.4 ng/mL occurred at a median (range) time of 5.0 (3, 8) hours after dosing (Figure 1).
The mean pharmacokinetic profiles for d-amphetamine and l-amphetamine after administration of ADZENYS ER and Mixed Salts of a Single Entity Amphetamine Extended Release Capsules in a crossover study are provided in Figure 1.
Figure 1: Mean Concentration of D-Amphetamine and L-Amphetamine vs Time for a 15 mL Dose of ADZENYS ER (18.8 mg amphetamine base equivalent) and Mixed Salts of a Single-Entity Amphetamine Product Extended-Release Capsules (MAS ER 30 mg) in the Fasted State
A single 15 mL dose of ADZENYS ER (18.8 mg amphetamine base equivalent) provided comparable plasma concentration profiles of both d-amphetamine and l-amphetamine to mixed salts of a single-entity amphetamine product extended-release capsules (MAS ER) 30 mg.
ffect of Food
High fat meal does not affect the extent of absorption of d-amphetamine and l-amphetamine but caused an 11% reduction in Cmax after administration of ADZENYS ER with or without food. This change is not considered clinically significant. The mean time to peak concentration (Tmax) for d-and l-amphetamine was about 5 hours after administration of ADZENYS ER with or without food.
Effect of Alcohol
In an in vitro alcohol-induced dose dumping study, a substantial increase in amphetamine release occurred in the presence of 40% alcohol but not with 5%, 10% and 20% alcohol.
Metabolism and Excretion
Amphetamine is reported to be oxidized at the 4 position of the benzene ring to form 4hydroxyamphetamine, or on the side chain α or ` β carbons to form alpha-hydroxy-amphetamine or norephedrine, respectively. Norephedrine and 4-hydroxy-amphetamine are both active and each is subsequently oxidized to form 4-hydroxy-norephedrine. Alpha-hydroxy-amphetamine undergoes deamination to form phenylacetone, which ultimately forms benzoic acid and its glucuronide and the glycine conjugate hippuric acid. Although the enzymes involved in amphetamine metabolism have not been clearly defined, CYP2D6 is known to be involved with formation of 4-hydroxy-amphetamine. Since CYP2D6 is genetically polymorphic, population variations in amphetamine metabolism are a possibility.
Amphetamine is known to inhibit monoamine oxidase, whereas the ability of amphetamine and its metabolites to inhibit various P450 isozymes and other enzymes has not been adequately elucidated. In vitro experiments with human microsomes indicate minor inhibition of CYP2D6 by amphetamine and minor inhibition of CYP1A2, 2D6, and 3A4 by one or more metabolites. However, due to the probability of auto-inhibition and the lack of information on the concentration of these metabolites relative to in vivo concentrations, no predications regarding the potential for amphetamine or its metabolites to inhibit the metabolism of other drugs by CYP isozymes in vivo can be made.
With normal urine pHs, approximately half of an administered dose of amphetamine is recoverable in urine as derivatives of alpha-hydroxy-amphetamine and approximately another 30-40% of the dose is recoverable in urine as amphetamine itself. Since amphetamine has a pKa of 9 .9, urinary recovery of amphetamine is highly dependent on pH and urine flow rates. Alkaline urine pHs result in less ionization and reduced renal elimination, and acidic pHs and high flow rates result in increased renal elimination with clearances greater than glomerular filtration rates, indicating the involvement of active secretion. Urinary recovery of amphetamine has been reported to range from 1% to 75%, depending on urinary pH, with the remaining fraction of the dose hepatically metabolized. Consequently, both hepatic and renal dysfunction have the potential to inhibit the elimination of amphetamine and result in prolonged exposures. In addition, drugs that effect urinary pH are known to alter the elimination of amphetamine, and any decrease in amphetamine’s metabolism that might occur due to drug interactions or genetic polymorphisms is more likely to be clinically significant when renal elimination is decreased [see DRUG INTERACTIONS].
Comparison of the pharmacokinetics of d-and l-amphetamine after oral administration of MAS ER in children (6-12 years) and adolescent (13-17 years) ADHD patients and healthy adult volunteers indicates that body weight is the primary determinant of apparent differences in the pharmacokinetics of d-and l-amphetamine across the age range. Systemic exposure measured by area under the curve to infinity (AUC∞) and maximum plasma concentration (Cmax) decreased with increases in body weight, while oral volume of distribution (VZ/F), oral clearance (CL/F), and elimination half-life (t1/2) increased with increases in body weight.
The pharmacokinetics of d-and l-amphetamine in pediatric patients has been evaluated based on the pharmacokinetics after administration of MAS ER to pediatric patients. On a mg/kg weight basis, pediatric patients eliminate amphetamine faster than adults. The elimination half-life (t1/2) is approximately 1 hour shorter for d-amphetamine and 2 hours shorter for l-amphetamine in pediatric patients than in adults. However, for a given dose of MAS ER, pediatric patients had higher systemic exposure to amphetamine (Cmax and AUC) than adults which was attributed to the higher dose administered to pediatric patients on a mg/kg body weight basis compared to adults. Upon dose normalization on a mg/kg basis, pediatric patients showed 30% less systemic exposure compared to adults.
The pharmacokinetics of d-and l-amphetamine after administration of ADZENYS ER was evaluated in a single dose pharmacokinetic study in 29 pediatric patients 6 -12 years with attention deficit hyperactivity disorder (ADHD). The patients were administered ADZENYS ER 18.8 mg orally in a single dose. The mean weight-normalized CL/F values for d-amphetamine and l-amphetamine increased 19.8% and 35.9% respectively, with an increase in age, while the V/F values for d-amphetamine and l-amphetamine decreased 22.2% and 21.5% respectively. Mean (±SD) T ½ decreased as age increased, ranging from 9.7 (1.0) hours in 10-12 years old to 16.7 (10.7) hours in 6-7 years old for d-amphetamine and from 10.6 (1.0) hours (10-12 years) to 24.6 (25.9) hours (6-7 years) for l-amphetamine.
Male And Female Patients
Systemic exposure to amphetamine was 20-30% higher in women (N=20) than in men (N=20) due to the higher dose administered to women on a mg/kg body weight basis. When the exposure parameters (Cmax and AUC) were normalized by dose (mg/kg), these differences diminished. Gender had no direct effect on the pharmacokinetics of d-and l-amphetamine.
Formal pharmacokinetic studies for race have not been conducted. However, amphetamine pharmacokinetics appeared to be comparable among Caucasians (N=33), Blacks (N=8) and Hispanics (N=10).
Animal Toxicology And/Or Pharmacology
Acute administration of high doses of amphetamine (d-or d,l-) has been shown to produce long-lasting neurotoxic effects, including irreversible nerve fiber damage, in rodents. The significance of these findings to humans is unknown.
The safety and efficacy of ADZENYS ER has been established based on adequate and well-controlled studies of mixed salts of a single-entity amphetamine product extended-release capsules in the treatment of ADHD. Below is a description of the results of the adequate and well-controlled studies of mixed salts of a single-entity amphetamine product extended-release capsules (MAS ER) in the treatment of ADHD.
A double-blind, randomized, placebo-controlled, parallel-group study was conducted in pediatric patients 6 to 12 years of age (N=584) who met DSM-IV criteria for ADHD (either the combined type or the hyperactive-impulsive type). Patients were randomized to fixed-dose treatment groups receiving final doses of 10, 20 or 30 mg of mixed salts of a single-entity amphetamine product extended-release capsules or placebo once daily in the morning for three weeks.
The primary efficacy variable was the Attention Deficit Hyperactivity Disorder-Rating Scale IV (ADHD-RS-IV) total score for the primary cohort. The ADHD-RS-IV is an 18-item scale that measures the core symptoms of ADHD. Significant improvements on the ADHD-RS-IV, based upon teacher ratings of attention and hyperactivity, were observed for all doses compared to patients who received placebo, for all three weeks, including the first week of treatment, when all subjects were receiving a dose of 10 mg/day. Patients who received MAS ER showed improvements on the ADHD-RS-IV total score in both morning and afternoon assessments compared to patients on placebo.
In a classroom analogue study, patients (N=51) receiving fixed doses of 10 mg, 20 mg or 30 mg MAS ER demonstrated statistically significant improvements on teacher-rated Swanson, Kotkin, Agler, M-Flynn, and Pelham (SKAMP) scale Attention and Deportment variables and Permanent Product Measure of Performance (PERMP) scales compared to patients treated with placebo. SKAMP is a validated 13-item teacher-rated scale that assesses manifestations of ADHD in a classroom setting. PERMP is a skill-adjusted math test that measures attention in ADHD.
A double-blind, randomized, multi-center, parallel-group, placebo-controlled study was conducted in pediatric patients 13 to 17 years of age (N=327) who met DSM-IV® criteria for ADHD. The primary cohort of patients (n=287, weighing ≤ 75kg) was randomized to fixed-dose treatment groups and received four weeks of treatment. Patients were randomized to receive final doses of 10 mg, 20 mg, 30 mg, and 40 mg MAS ER or placebo once daily in the morning. Patients randomized to doses greater than 10 mg were titrated to their final doses by 10 mg each week. Improvements in the primary cohort were statistically significantly greater in all four primary cohort active treatment groups (MAS ER 10 mg, 20 mg, 30 mg, and 40 mg) compared with the placebo group. There was not adequate evidence that doses greater than 20 mg/day conferred additional benefit.
A double-blind, randomized, placebo-controlled, parallel-group study was conducted in adults (N=255) who met DSM-IV® criteria for ADHD. Patients were randomized to fixed-dose treatment groups receiving final doses of 20, 40, or 60 mg of MAS ER or placebo once daily in the morning for four weeks. Improvements, measured with the Attention Deficit Hyperactivity Disorder-Rating Scale (ADHD-RS), were observed at endpoint for all MAS ER doses compared to patients who received placebo for all four weeks. However, there was not adequate evidence that doses greater than 20 mg/day conferred additional benefit.
