(amphetamine sulfate) Orally Disintegrating Tablets, CII
ABUSE AND DEPENDENCE
CNS stimulants, including EVEKEO ODT, 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 WARNINGS AND PRECAUTIONS, and Drug Abuse And Dependence].
EVEKEO ODT orally disintegrating tablets contain amphetamine sulfate, a CNS stimulant, as a 1 to 1 ratio of dextroamphetamine sulfate and levoamphetamine sulfate (d- and l-amphetamine sulfate). Amphetamine sulfate is a white, odorless crystalline powder. It has a slightly bitter taste. Its solutions are acid to litmus, having a pH of 5 to 8. It is freely soluble in water, slightly soluble in alcohol and practically insoluble in ether.
Each EVEKEO ODT tablet contains 5 mg, 10 mg, 15 mg, or 20 mg of racemic amphetamine sulfate. Each tablet also contains the following inactive ingredients: amino methacrylate copolymer, citric acid, crospovidone, ethylcellulose, dibutyl sebacate, magnesium stearate, malic acid, mannitol, microcrystalline cellulose, and sucralose.
EVEKEO ODT is indicated for the treatment of Attention Deficit Hyperactivity Disorder (ADHD) in pediatric patients 6 to 17 years of age [see Clinical Studies].
DOSAGE AND ADMINISTRATION
Prior to treating patients with EVEKEO ODT, 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 EVEKEO ODT use [see WARNINGS AND PRECAUTIONS, and Drug Abuse And Dependence].
Administer EVEKEO ODT orally in the morning with or without food or liquid.
The recommended starting dose of EVEKEO ODT for patients 6 to 17 years of age is 5 mg once or twice daily. If necessary, administer an additional dose after 4 to 6 hours. Titrate the dosage in increments of 5 mg at weekly intervals until optimal response is obtained. Only in rare cases will it be necessary to exceed a total of 40 mg daily.
Where possible, drug administration should be interrupted occasionally to determine if there is a recurrence of behavioral symptoms sufficient to require continued therapy.
Amphetamine should be administered at the lowest effective dosage and dosage should be individually adjusted.
Instruct the patient or caregiver on the following administration instructions:
- Do not remove the tablet from the blister pack until just prior to dosing. Do not store the tablet for future use.
- Use dry hands to open the blister.
- Remove the tablet by pushing it through the back of the foil-lined blister pack.
- As soon as the blister is opened, remove the tablet and place the tablet on the patient’s tongue.
- Place the whole tablet on the tongue and allow it to disintegrate without chewing or crushing.
- The tablet will disintegrate in saliva so that it can be swallowed. No liquid is needed to take the tablet. The tablet can be actively moved around between the tongue and the roof of the mouth until it disintegrates.
Switching From Other Amphetamine Products
Switching from EVEKEO to EVEKEO ODT can be done on a milligram-per-milligram basis.
When switching from other amphetamine products, discontinue treatment and titrate with EVEKEO ODT using the titration schedule above. Do not substitute for other amphetamine products on a milligram-per-milligram basis because of different amphetamine salt compositions and differing pharmacokinetic profiles [see DESCRIPTION, CLINICAL PHARMACOLOGY].
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 EVEKEO ODT dosage accordingly [see DRUG INTERACTIONS].

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.
Study 1 was conducted with EVEKEO tablets (i.e., not the ODT formulation) in children ages 6 to 12 years who met Diagnostic and Statistical Manual of Mental Disorders, 4th edition, Text Revision (DSM-IV-TR) criteria for ADHD. This study began with an 8-week, open-label, dose-optimization phase followed by a 2-week double-blind, placebo-controlled, randomized, crossover phase. Adverse reactions reported in > 5% of patients (N=105; doses of 10 to 40 mg/day) during the open-label phase included: decreased appetite (28%), infections (22%), abdominal pain (15%), irritability (14%), headache (13%), nausea (6%), vomiting (6%), affect lability (includes mood swings; 9%), tachycardia (9%), insomnia (10%), fatigue (10%),and dry mouth (6%). During the open-label phase, six patients discontinued due to adverse reactions: irritability (n=3), affect lability (n=1), initial insomnia (n=1), and rash (n=1).
Table 1 lists the adverse reactions reported during the double-blind, cross-over phase. No patient discontinued the study for an adverse reaction during the double-blind crossover phase. Because of the trial design (an initial 8-week, open-label, active treatment phase), the adverse reaction rates described in the double-blind phase are lower than expected in clinical practice.

Drugs Having Clinically Important Interactions With Amphetamines
Table 2: 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 EVEKEO ODT during or within 14 days following the administration of MAOI [see CONTRAINDICATIONS].|
|Examples||selegiline, isocarboxazid, phenelzine, tranylcypromine, linezolid, methylene blue|
|Clinical Impact||The concomitant use of EVEKDO ODT 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 EVEKEO ODT initiation or dosage increase. If serotonin syndrome occurs, discontinue EVEKEO ODT and 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||May increase exposure to amphetamine and exacerbate the action of amphetamine.|
|Intervention||Caution should be taken when co-administering EVEKEO ODT and gastrointestinal and urinary alkalinizing agents.|
|Examples||Gastrointestinal alkalinizing agents (e.g., sodium bicarbonate; proton pump inhibitors [e.g. omeprazole]) Urinary alkalinizing agents (e.g. acetazolamide, some thiazides)|
|Clinical Impact||Lower blood levels and efficacy of amphetamines.|
|Intervention||Increase dose of EVEKEO ODT based on clinical response.|
|Examples||Gastrointestinal acidifying agents (e.g., guanethidine, reserpine, glutamic acid HCl, ascorbic acid) Urinary acidifying agents (e.g., ammonium chloride, sodium acid phosphate, methenamine salts)|
|Clinical Impact||May enhance the activity of tricyclic or sympathomimetic agents causing sustained increases in the concentration of d- amphetamine in the brain; cardiovascular effects can be potentiated.|
|Intervention||Monitor frequently and adjust EVEKEO ODT dose or use alternative therapy based on clinical response.|
|Clinical Impact||The concomitant use of EVEKEO ODT and CYP2D6 inhibitors may increase the exposure of EVKEO ODT compared to the use of the drug alone and increase the risk of serotonin syndrome.|
|Intervention||Initiate with lower doses and monitor patients for signs and symptoms of serotonin syndrome particularly during EVEKEO ODT initiation and after a dosage increase. If serotonin syndrome occurs, discontinue EVEKEO ODT and the CYP2D6 inhibitor. Alternatively, consider using a drug that does not inhibit CYP2D6 [see WARNINGS AND PRECAUTIONS and OVERDOSAGE].|
|Examples||paroxetine and fluoxetine (also serotonergic drugs), quinidine, ritonavir.|
Drug-Laboratory Test Interactions
Drug Abuse And Dependence
EVEKEO ODT contains amphetamine, a Schedule II controlled substance.
EVEKEO ODT is a CNS stimulant that contains amphetamine which has a high potential for abuse. Abuse is characterized by impaired control over drug use, compulsive use, continued 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 seen. Abusers of amphetamine may use unapproved routes of administration which can result in overdose and death [see OVERDOSAGE].
To reduce the abuse of CNS stimulants, including EVEKEO ODT, assess the risk of abuse prior to prescribing. After prescribing, keep careful prescription records, educate patients and their families about abuse and on proper storage and disposal of CNS stimulants. Monitor for signs of abuse while on therapy, and re-evaluate the need for EVEKEO ODT use.
Tolerance (a state of adaptation in which exposure to a specific dose of a drug results in a reduction of the drug's desired and/or undesired effects over time, in such a way that a higher dose of the drug is required to produce the same effect that was once obtained at a lower dose) may occur during the chronic therapy of CNS stimulants including EVEKEO ODT.
Physical dependence (a state of adaptation 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 EVEKEO ODT. 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; psychomotor retardation or agitation.
Included as part of the PRECAUTIONS section.
Potential For Abuse and Dependence
CNS stimulants, including EVEKEO ODT, 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 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 pediatric patients 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 EVEKEO ODT treatment.
Blood Pressure And Heart Rate Increases
Psychiatric Adverse Reactions
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 EVEKEO ODT. 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 EVEKEO ODT.
Patients who are not growing or gaining height or weight as expected may need to have their treatment interrupted [Use in Specific Populations (8.4)].
There is some clinical evidence that stimulants may lower the convulsive threshold in patients with prior history of seizures, in patients with prior EEG abnormalities in absence of seizures, and, very rarely, in patients without a history of seizures and no prior EEG evidence of seizures. In the presence of seizures, discontinue EVEKEO ODT.
Peripheral Vasculopathy, Including Raynaud’s Phenomenon
Stimulants, including EVEKEO ODT, 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 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 EVEKEO ODT. 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 EVEKEO ODT and any concomitant serotonergic agents immediately if the above symptoms occur, and initiate supportive symptomatic treatment. If concomitant use of EVEKEO ODT with other serotonergic drugs or CYP2D6 inhibitors is clinically warranted, initiate EVEKEO ODT 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.
Patient Counseling Information
Advise the patient to read the FDA-approved patient labeling (Medication Guide).
Controlled Substance Status/Potential For Abuse, Misuse, And Dependence

Serious Cardiovascular Risks
Advise patients, caregivers, and family members that there is a potential serious cardiovascular risk (including sudden death, myocardial infarction, stroke, and hypertension) with EVEKEO ODT. 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 and their caregivers that EVEKEO ODT can cause elevations of their blood pressure and pulse rate and that patients should be monitored for such effects [see WARNINGS AND PRECAUTIONS].
Advise patients and their caregivers that EVEKEO ODT, at recommended doses, may cause psychotic symptoms or mania 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 EVEKEO ODT 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 and their caregivers beginning treatment with EVEKEO ODT about the risk of peripheral vasculopathy, including Raynaud's phenomenon, and associated signs and symptoms: fingers or toes may feel numb, cool, painful, and/or may change 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 EVEKEO ODT. Further clinical evaluation (e.g. rheumatology referral) may be appropriate for certain patients [see WARNINGS AND PRECAUTIONS].
Caution patients and their caregivers about the risk of serotonin syndrome with concomitant use of EVEKEO ODT 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 and their caregivers 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 EVEKEO ODT 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 EVEKEO ODT [see Use In Specific Populations ]. Advise patients of the potential fetal effects from the use of EVEKEO ODT during pregnancy [see Use In Specific Populations].
Advise patients not to breastfeed if they are taking EVEKEO ODT [see Use In Specific Populations].
Carcinogenesis, Mutagenesis, Impairment Of Fertility
No evidence of carcinogenicity was found in studies in which d-, l-amphetamine (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 2, 1, and 0. 5 times, respectively, the maximum recommended human dose of 40 mg/day given to children, on a mg/m² basis.
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.
Use In Specific Populations
Pregnancy Exposure Registry
There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to EVEKEO ODT during pregnancy. Healthcare providers are encouraged to register patients by calling the National Pregnancy Registry for Psychostimulants at 1-866961-2388 or visiting online at https://womensmentalhealth.org/clinical-and-research-programs/pregnancyregistry/othermedications/.
Available data from published epidemiologic studies and postmarketing reports on use of prescription amphetamine in pregnant women have not identified a drug-associated risk of major birth defects and miscarriage. Adverse pregnancy outcomes, including premature delivery and low birth weight, have been seen in infants born to mothers taking amphetamines during pregnancy (see Clinical Considerations).
Dextroamphetamine sulfate has been shown to have embryotoxic and teratogenic effects when administered to A/Jax mice and C57BL mice in doses approximately 41 times the maximum human dose. Embryotoxic effects were not seen in New Zealand white rabbits given the drug in doses 7 times the human dose nor in rats given 12.5 times the maximum human dose.
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% to 4% and 15 to 20%, respectively.
Fetal/Neonatal Adverse Reactions
Amphetamines, such as EVEKEO ODT, cause vasoconstriction and thereby decrease placental perfusion. In addition, amphetamines can stimulate uterine contractions, increasing the risk of premature delivery. Infants born to mothers taking amphetamines during pregnancy 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.
Based on limited case reports in published literature, amphetamine (d- or d1) 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 amphetamine 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 breast feeding is not recommended during treatment with EVEKEO ODT.
The safety and effectiveness of EVEKEO ODT have been established in pediatric patients 6 years and older. Use of EVEKEO ODT is based on one adequate and well-controlled study with another immediate-release amphetamine sulfate product (EVEKEO) in pediatric patients 6 to 12 years [see Clinical Studies], along with dosing and safety information for other amphetamine products.
Safety and efficacy in pediatric patients below the age of 6 years have not been established.
Long-Term Growth Suppression
Growth should be monitored during treatment with stimulants, including EVEKEO ODT. Pediatric patients aged 6 to 17 years who are not growing or gaining weight as expected may need to have their treatment interrupted [see WARNINGS AND PRECAUTIONS, ADVERSE REACTIONS].
EVEKEO ODT has not been studied in patients over the age of 65 years.
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.
D-amphetamine is not dialyzable.
EVEKEO ODT is contraindicated in patients:
- With known hypersensitivity to amphetamine, or other components of EVEKEO ODT. Hypersensitivity reactions such as angioedema and anaphylactic reactions have been reported in patients treated with other amphetamine products [see ADVERSE REACTIONS].
- Receiving concomitant treatment with monoamine oxidase inhibitors (MAOIs), or within 14 days following discontinuation of treatment with an MOAI (including MAOIs such as linezolid or intravenous methylene blue), because of an increased risk of hypertensive crisis [see WARNINGS AND PRECAUTIONS, DRUG INTERACTIONS].
Mechanism Of Action
Amphetamines are non-catecholamine sympathomimetic amines with central nervous system (CNS) stimulant activity. The mode of therapeutic action in ADHD is not known.
EVEKEO ODT is a 1:1 racemic mixture of d- and l-amphetamine. The l-isomer is more potent than the d-isomer in cardiovascular activity while the d-isomer is more potent than the l-isomer in causing CNS excitatory effects.
Amphetamine demonstrates linear pharmacokinetics over the dose range of 5 to 40 mg.
Following a single-dose oral administration of Evekeo ODT 20 mg disintegrated/dissolved in the oral cavity in healthy subjects in a crossover study, exposures (Cmax and AUC) to d-and l-amphetamine were comparable to that after administration of equal dose of immediate-release amphetamine sulfate tablets (Evekeo) tablets swallowed intact with water.
Median (range) Tmax of d- and l-amphetamine was reached at approximately 3.5 (2-8) hours and 3.0 (1 -6) hours after administration without water and with water, respectively.
Effect Of Food
Administration of food (a high fat meal) does not affect the observed AUC and Cmax of d-and l-amphetamine after single-dose oral administration of EVEKEO ODT (20 mg) in healthy adults who allowed the tablet to be disintegrated/dissolved in their oral cavity prior to swallowing without water. Median (range) Tmax increased from 2.5 (1.5 – 6) hours to 4.5 (2.5 – 8.0) hours when administration without compared to with food.
Amphetamine undergoes both hepatic and renal elimination. The plasma elimination half-life of d- and l-amphetamine averaged 10.0 and about 11.7 hours in healthy adult volunteers.
Amphetamine d-and l- enantiomers are highly metabolized largely by two primary oxidative pathways, one via CYP2D6 to produce active metabolite 4-hydroxyamphetamine, and the other by oxidative deamination. CYP2D6 is one of several enzymes involved in the biotransformation of amphetamine.
Amphetamine is renally eliminated in a pH-dependent manner. The renal excretion rate of unchanged amphetamine at a urine pH of 6.6 averages 70% versus 17% - 43% at urine pH of >6.7.
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 effectiveness of EVEKEO ODT for the treatment of ADHD has been established based on an adequate and well-controlled study of immediate-release amphetamine sulfate (EVEKEO). Below is a description of this study and its results.
Study 1 (NCT01986062) was conducted with EVEKEO tablets in children ages 6 to 12 years who met DSM-IV-TR criteria for ADHD. Following 8 weeks of open-label dose optimization, patients were randomly assigned to continue their optimized dose of EVEKEO (10 to 40 mg/day in divided doses) or placebo for 1 week. After 1 week, patients crossed-over to receive the alternate treatment. At the end of each treatment week, efficacy assessments were conducted at 0.75, 2, 4, 6, 8, and 10 hours post-dose using the Swanson, Kotkin, Agler, M-Flynn, and Pelham (SKAMP) rating scale. SKAMP is a 13-item teacher-rated scale that assesses manifestations of ADHD in a classroom setting. The SKAMP-Combined score was obtained by summing items 1 through 13. The primary efficacy outcome assessed by the SKAMP-Combined score at 2 hours postdose was statistically significantly better in EVEKEO treatment compared to placebo (Table 3). Key secondary efficacy endpoints were the time-to-onset and duration-of-effect of EVEKEO using SKAMP-Combined scores. SKAMP-Combined scores were statistically significantly better for patients in the EVEKEO treatment group compared to patients in the placebo treatment group beginning at 0.75 hours post-dose and at each assessment through 10 hours post-dose.
