Indications
Bupropion Hydrochloride is indicated in the treatment of depression. Bupropion is also indicated in smoking cessation.
Dosage & Administration
The usual adult target dose for Bupropion is 300 mg/day, given as 150 mg, twice daily. Dosing should begin at 150 mg/day given as a single daily dose in the morning. If the 150 mg initial dose is adequately tolerated, an increase to the 300 mg/day target dose, given as 150 mg twice daily, may be made as early as day 4 of dosing. There should be an interval of at least 8 hours between successive doses.
Increasing the dosage above 300 mg/day: As with other antidepressants, the full antidepressant effect of Bupropion Hydrochloride may not be evident until 4 weeks of treatment or longer. An increase in dosage to the maximum of 400 mg/day, given as 200 mg twice daily, may be considered for patients in whom no clinical improvement is noted after several weeks of treatment at 300 mg/day. Bupropion Hydrochloride should be discontinued in patients who do not demonstrate an adequate response after an appropriate period of treatment at 450 mg/day.
Maintenance: The lowest dose that maintains remission is recommended. Although it is not known how long the patient should remain on Bupropion Hydrochloride, it is generally recognised that acute episodes of depression require several months or longer of antidepressant drug treatment.
Side Effects
Agitation, anxiety, and insomnia often occur during the initial stages of Bupropion therapy. Other relatively common side effects reported with Bupropion include fever, dry mouth, headache or migraine, dizziness, nausea and vomiting, constipation, tremor, sweating, and skin rashes. Hypersensitivity reactions, ranging from pruritus and urticaria, less commonly, angio-oedema, dyspnoea, and anaphylactoid reactions have been reported.
Pregnancy & Lactation
Pregnancy Category C. There are no adequate and well controlled studies in pregnant women. This drug should be used during pregnancy only if clearly needed.
Lactation: Bupropion and its metabolites are secreted in human milk. Because Bupropion is excreted in human milk, a decision should be made whether to discontinue breast feeding or to discontinue the drug.
Precautions & Warnings
It should be used with extreme caution, in patients with history of seizure disorders or in patients with other predisposing factors such as severe hepatic cirrhosis or a CNS tumour, and in those undergoing abrupt withdrawal from alcohol or Benzodiazepines. The use of Bupropion in patients with other risk factors for seizures (for example, alcohol abuse, a history of head trauma, diabetes, and drugs known to lower the seizure threshold) should only be undertaken when there are compelling clinical reasons. Bupropion should be used with caution in patients with bipolar depression or psychoses and in patients with a recent history of myocardial infarction or unstable heart disease and in hepatic or renal impairment.
