Aplenzin (bupropion hydrobromide) is an antidepressant used to treat major depressive disorder (MDD) and seasonal affective disorder. The Zyban brand of bupropion is used to help people stop smoking by reducing cravings and other withdrawal effects. Common side effects include dry mouth, sore throat, nausea, vomiting, stomach/abdominal pain, flushing, headache, loss of appetite, constipation, trouble sleeping, increased sweating, strange taste in mouth, joint aches, dizziness, or blurred vision. Antidepressants may increase the risk of suicidal thinking and behavior (suicidality) in children, adolescents, and young adults. Tell your doctor if this occurs.

The recommended starting dose of Aplenzin for MDD is 174 mg once daily in the morning. After 4 days, the dose may be increased to the target dose of 348 mg once daily in the morning. Aplenzin may interact with medication used to prevent blood clots, cancer medicines, heart or blood pressure medications, HIV/AIDS medications, other antidepressants, medicines to treat psychiatric disorders, antihistamines, asthma medications or bronchodilators, birth control pills or estrogens, bladder or urinary medications, antibiotics, diet pills, stimulants, ADHD medications, insulin or oral diabetes medications, medications for nausea, vomiting, or motion sickness; anti-malarials; Parkinson's medications, restless leg syndrome, or pituitary gland tumor (prolactinoma); organ transplant medicines, narcotics, sedatives, steroids, street drugs, theophylline, or ulcer or irritable bowel medications. Tell your doctor all medications and supplements you use. Aplenzin should be used only when prescribed during pregnancy. Infrequently, newborns whose mothers have used certain antidepressants during the last 3 months of pregnancy may develop symptoms including persistent feeding or breathing difficulties, jitteriness, seizures or constant crying. Tell your doctor if you notice these symptoms in your newborn. Do not stop taking this medication unless your doctor directs you to do so. Aplenzin passes into breast milk and may have undesirable effects on a nursing infant. Consult your doctor before breastfeeding.

Tell your doctor right away if you have any serious side effects, including: fast/pounding/irregular heartbeat, mental/mood changes (such as anxiety, agitation, confusion, unusual behavior/thinking, memory loss), unusual weight loss or gain.

Stop taking bupropion and get medical help right away if you have any very serious side effects, including: seizure.

A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), painful sores in the mouth/around the eyes, severe dizziness, trouble breathing.

(Adverse Reactions)

SIDE EFFECTS

The following adverse reactions are discussed in greater detail in other sections of the labeling:

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.

Commonly Observed Adverse Reactions in Controlled Clinical Trials of Sustained-Release Bupropion Hydrochloride

Adverse reactions that occurred in at least 5% of patients treated with bupropion HCl sustainedrelease (300 mg and 400 mg per day) and at a rate at least twice the placebo rate are listed below.

300 mg/day of bupropion HCl sustained-release (equivalent to APLENZIN 348 mg/day): anorexia, dry mouth, rash, sweating, tinnitus, and tremor.

400 mg/day of bupropion HCl sustained-release (equivalent to APLENZIN 464 mg/day): abdominal pain, agitation, anxiety, dizziness, dry mouth, insomnia, myalgia, nausea, palpitation, pharyngitis, sweating, tinnitus, and urinary frequency.

APLENZIN is bioequivalent to bupropion HCl extended-release, which has been demonstrated to have similar bioavailability both to the immediate-release formulation of bupropion and to the sustained-release formulation of bupropion. The information included under this subsection and under the subsections 6.2 and 6.3 is based primarily on data from controlled clinical trials with the sustained-release and extended-release formulations of bupropion hydrochloride.

Major Depressive Disorder

Adverse Reactions Leading to Discontinuation of Treatment with Bupropion HCl Immediate-Release, Bupropion HCl Sustained-Release, and Bupropion HCl Extended- Release in Major Depressive Disorder Trials

In placebo-controlled clinical trials with bupropion HCl sustained-release, 4%, 9%, and 11% of the placebo, 300 mg/day and 400 mg/day groups, respectively, discontinued treatment because of adverse reactions. The specific adverse reactions leading to discontinuation in at least 1% of the 300 mg/day or 400 mg/day groups and at a rate at least twice the placebo rate are listed in Table 3.

Table 3: Treatment Discontinuation Due to Adverse Reactions in Placebo-Controlled Trials in MDD

Migraine 0.3% 0.0% 1.8%
* Equivalent to 348 mg/day bupropion HBr
** Equivalent to 464 mg/day bupropion HBr

In clinical trials with bupropion HCl immediate-release, 10% of patients and volunteers discontinued due to an adverse reaction. Reactions resulting in discontinuation, (in addition to those listed above for the sustained-release formulation), included vomiting, seizures, and sleep disturbances.

Adverse Reactions Occurring at an Incidence of > 1% in Patients Treated with Bupropion HCl Immediate-Release or Bupropion HCl Sustained-Release in MDD

Table 4 summarizes the adverse reactions that occurred in placebo-controlled trials in patients treated with bupropion HCl sustained-release 300 mg/day and 400 mg/day. These include reactions that occurred in either the 300 mg or 400 mg group at an incidence of 1% or more and were more frequent than in the placebo group are included.

The following additional adverse reactions occurred in controlled trials of bupropion HC1 immediate-release (300 to 600 mg per day) at an incidence of at least 1% more frequently than in the placebo group were: cardiac arrhythmia (5% vs. 4%), hypertension (4% vs. 2%), hypotension (3% vs. 2%), tachycardia (11% vs. 9%), appetite increased (4% vs. 2%), dyspepsia (3% vs. 2%), menstrual complaints (5% vs. 1%), akathisia (2% vs. 1%), impaired sleep quality (4% vs. 2%), sensory disturbance (4% vs. 3%), confusion (8% vs. 5%), decreased libido (3% vs. 2%), hostility (6% vs. 4%), auditory disturbance (5% vs. 3%), and gustatory disturbance (3% vs. 1%).

Seasonal Affective Disorder

In placebo-controlled clinical trials in SAD, 9% of patients treated with bupropion HCl extended-release and 5% of patients treated with placebo discontinued treatment because of adverse reactions. The adverse reactions leading to discontinuation in at least 1% of patients treated with bupropion and at a rate numerically greater than the placebo rate were insomnia (2% vs. < 1%) and headache (1% vs. < 1%).

Table 5 summarizes the adverse reactions that occurred in patients treated with bupropion HCl extended-release for up to approximately 6 months in 3 placebo-controlled trials. These include reactions that occurred at an incidence of 2% or more and were more frequent than in the placebo group.
