Monitoring of blood pressure is recommended in patients who receive the combination of bupropion and nicotine replacement.
There are no controlled trials assessing the safety of bupropion in patients with a recent history of myocardial infarction or unstable cardiac disease. The risk appears to be increased in patients with bipolar disorder or who have risk factors for bipolar disorder. Some of these patients had a diagnosis of bipolar disorder. Reactions have been characterized by pruritus , urticaria , angioedema , and dyspnea requiring medical treatment.
In addition, there have been rare, spontaneous postmarketing reports of erythema multiforme , Stevens-Johnson syndrome , and anaphylactic shock associated with bupropion. There are reports of arthralgia , myalgia , fever with rash and other serum sickness-like symptoms suggestive of delayed hypersensitivity. Instruct patients, their families, and their caregivers to read the Medication Guide and assist them in understanding its contents.

Each tablet contains the labeled amount of bupropion hydrochloride and the inactive ingredients: Bupropion is a relatively weak inhibitor of the neuronal uptake of norepinephrine and dopamine, and does not inhibit monoamine oxidase or the re-uptake of serotonin.
Bupropion is a racemic mixture. The pharmacologic activity and pharmacokinetics of the individual enantiomers have not been studied. There was equivalence for bupropion AUCs, as well as equivalence for both peak plasma concentration and AUCs for all 3 of the detectable bupropion metabolites. Thus, at steady state, bupropion hydrochloride extended-release tablets SR , given twice daily, and the immediate-release formulation of bupropion, given 3 times daily, are essentially bioequivalent for both bupropion and the 3 quantitatively important metabolites.
Following oral administration of bupropion hydrochloride extended-release tablets SR to healthy volunteers, peak plasma concentrations of bupropion are achieved within 3 hours. The extent of protein binding of the hydroxybupropion metabolite is similar to that for bupropion, whereas the extent of protein binding of the threohydrobupropion metabolite is about half that seen with bupropion. Bupropion is extensively metabolized in humans. Three metabolites have been shown to be active: In vitro findings suggest that cytochrome PIIB6 CYP2B6 is the principal isoenzyme involved in the formation of hydroxybupropion, while cytochrome P isoenzymes are not involved in the formation of threohydrobupropion.
Oxidation of the bupropion side chain results in the formation of a glycine conjugate of meta-chlorobenzoic acid, which is then excreted as the major urinary metabolite. The potency and toxicity of the metabolites relative to bupropion have not been fully characterized. However, it has been demonstrated in an antidepressant screening test in mice that hydroxybupropion is one-half as potent as bupropion, while threohydrobupropion and erythrohydrobupropion are 5-fold less potent than bupropion.
This may be of clinical importance because the plasma concentrations of the metabolites are as high or higher than those of bupropion. Following a single dose in humans, peak plasma concentrations of hydroxybupropion occur approximately 6 hours after administration of bupropion hydrochloride extended-release tablets SR. Peak plasma concentrations of hydroxybupropion are approximately 10 times the peak level of the parent drug at steady state. Do not take extra medicine to make up the missed dose.
