Bupropion (HCl) is an antidepressant chemically unrelated to other classes of antidepressants. It weakly inhibits the neuronal reuptake of serotonin, dopamine and noradrenaline.Bupropion (HCl) is also used as an aid to smoking cessation in combination with motivational support.
Interactions
Bupropion (HCl) is known to interact with other drugs, the details of drug interactions is as follows:DrugDetailsSeverityOnsetManagementCarbamazepinePlasma concentration of Bupropion reduced by Carbamazepine.Cimetidine (HCl)Diphenyl PyralineFluoxetine (HCl)FluspirileneLikely interaction of FLUSPIRILENE increasing the CONVULSANT effect of BUPROPION. May need to avoid combination.ModerateIprindoleLikely interaction of IPRINDOLE increasing the CONVULSANT effect of BUPROPION. Moderate risk.ModerateMay need to avoid combination.Iproniazid PhosphateLikely interaction of IPRONIAZID increasing the CONVULSANT effect of BUPROPION. ModerateMay need to avoid combination.LevodopaIncreased risk of side effects when Bupropion given with Levodopa.LithiumLofepramine (HCl)Likely interaction of LOFEPRAMINE increasing the CONVULSANT effect of BUPROPION. ModerateMay need to avoid combinationMoclobemideADVICE: Avoid concomitant use with Moclobemide.MajorOpiumConcurrent use may increase a dose-related risk of seizures. OxymorphoneThe use of bupropion is associated with a dose-related risk of seizures. The estimated incidence of seizures is approximately 0.1% at dosages up to 300 mg/day and 0.4% at dosages between 300 to 450 mg/day, but increases almost tenfold between 450 mg and 600 mg/day. The risk may also be increased during coadministration with selective serotonin reuptake inhibitors (SSRI antidepressants or anorectics), monoamine oxidase inhibitors, neuroleptic agents, central nervous system stimulants, opioids, tricyclic antidepressants, other tricyclic compounds (e.g., cyclobenzaprine, phenothiazines), systemic steroids, and/or any substance that can reduce the seizure threshold (e.g., carbapenems, cholinergic agents, fluoroquinolones, interferons, chloroquine, mefloquine, lindane, theophylline). These agents are often individually epileptogenic and may have additive effects when combined.MajorExtreme caution is advised if bupropion is administered with any substance that can reduce the seizure threshold, particularly in the elderly and in patients with a history of seizures or other risk factors for seizures (e.g., head trauma; brain tumor; severe hepatic cirrhosis; metabolic disorders; CNS infections; excessive use of alcohol or sedatives; addiction to opiates, cocaine, or stimulants; diabetes treated with oral hypoglycemic agents or insulin). Bupropion as well as concomitant medications should be initiated at the lower end of the dose range and titrated gradually if feasible. The total dose of bupropion should generally not exceed 450 mg/day (or 150 mg every other day in patients with severe hepatic cirrhosis). Bupropion should be discontinued and not restarted in patients who experience a seizure during treatment.OxypertineLikely interaction of OXYPERTINE increasing the CONVULSANT effect of BUPROPION.
