However, there is substantial evidence from placebo-controlled maintenance trials in adults with depression that the use of antidepressants can delay the recurrence of depression. All patients being treated with antidepressants for any indication should be monitored appropriately and observed closely for clinical worsening, suicidality, and unusual changes in behavior, especially during the initial few months of a course of drug therapy, or at times of dose changes, either increases or decreases [see BOX WARNING ].

The following symptoms, anxiety, agitation, panic attacks, insomnia, irritability, hostility, aggressiveness, impulsivity , akathisia psychomotor restlessness , hypomania , and mania , have been reported in adult and pediatric patients being treated with antidepressants for major depressive disorder as well as for other indications, both psychiatric and nonpsychiatric.

Families and caregivers of patients being treated with antidepressants for MDD or other indications, both psychiatric and nonpsychiatric, should be alerted about the need to monitor patients for the emergence of agitation, irritability, unusual changes in behavior, and the other symptoms described above, as well as the emergence of suicidality, and to report such symptoms immediately to healthcare providers.

Such monitoring should include daily observation by families and caregivers. Serious neuropsychiatric adverse events have been reported in patients taking bupropion for smoking cessation. These postmarketing reports have included changes in mood including depression and mania , psychosis , hallucinations, paranoia, delusions, homicidal ideation, aggression, hostility, agitation, anxiety, and panic, as well as suicidal ideation, suicide attempt, and completed suicide [see ADVERSE REACTIONS ].

Some patients who stopped smoking may have been experiencing symptoms of nicotine withdrawal, including depressed mood. Depression, rarely including suicidal ideation, has been reported in smokers undergoing a smoking cessations attempt without medication.

However, some of these adverse events occurred in patients taking bupropion who continued to smoke. Neuropsychiatric adverse events occurred in patients without and with pre-existing psychiatric disease; some patients experienced worsening of their psychiatric illnesses. Observe patients for the occurrence of neuropsychiatric adverse events. In many postmarketing cases, resolution of symptoms after discontinuation of bupropion was reported.

However, the symptoms persisted in some cases; therefore, ongoing monitoring and supportive care should be provided until symptoms resolve. The risk of seizure is dose-related. The dose should not exceed mg per day.

Increase the dose gradually. The risk of seizures is also related to patient factors, clinical situations, and concomitant medications that lower the seizure threshold. The following conditions can also increase the risk of seizure: Data from a comparative trial of the sustained-release formulation of bupropion HCl, nicotine transdermal system NTS , the combination of sustained-release bupropion plus NTS, and placebo as an aid to smoking cessation suggest a higher incidence of treatment-emergent hypertension in patients treated with the combination of sustained-release bupropion and NTS.

In this trial, 6. The majority of these subjects had evidence of pre-existing hypertension. 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. Instruct patients to contact a healthcare professional if such reactions occur. 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.

Patients should be given the opportunity to discuss the contents of the Medication Guide and to obtain answers to any questions they may have. The complete text of the Medication Guide is reprinted at the end of this document. Advise families and caregivers of patients to observe for the emergence of such symptoms on a day-to-day basis, since changes may be abrupt. Symptoms such as these may be associated with an increased risk for suicidal thinking and behavior and indicate a need for very close monitoring and possibly changes in the medication.

Inform patients that some patients have experienced changes in mood including depression and mania , psychosis, hallucinations, paranoia, delusions, homicidal ideation, aggression, hostility, agitation, anxiety, and panic, as well as suicidal ideation and suicide when attempting to quit smoking while taking bupropion. Advise patients to minimize or avoid use of alcohol. Pre-existing glaucoma is almost always open-angle glaucoma because angle-closure glaucoma, when diagnosed, can be treated definitively with iridectomy.

Open-angle glaucoma is not a risk factor for angle-closure glaucoma. Three metabolites are active: In vitro findings suggest that CYP2B6 is the principal isoenzyme involved in the formation of hydroxybupropion, while cytochrome P enzymes 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. The times to peak concentrations for the erythrohydrobupropion and threohydrobupropion metabolites are similar to that of hydroxybupropion. Population Subgroups Factors or conditions altering metabolic capacity e. The elimination of the major metabolites of bupropion may be affected by reduced renal or hepatic function, because they are moderately polar compounds and are likely to undergo further metabolism or conjugation in the liver prior to urinary excretion.

Renal Impairment There is limited information on the pharmacokinetics of bupropion in patients with renal impairment. An inter-trial comparison between normal subjects and subjects with end-stage renal failure demonstrated that the parent drug Cmax and AUC values were comparable in the 2 groups, whereas the hydroxybupropion and threohydrobupropion metabolites had a 2.

A second study, comparing normal subjects and subjects with moderate-to-severe renal impairment GFR Bupropion is extensively metabolized in the liver to active metabolites, which are further metabolized and subsequently excreted by the kidneys. The elimination of the major metabolites of bupropion may be reduced by impaired renal function.

Hepatic Impairment The effect of hepatic impairment on the pharmacokinetics of bupropion was characterized in 2 single-dose trials, one in subjects with alcoholic liver disease and one in subjects with mild to severe cirrhosis. The differences in half-life for bupropion and the other metabolites in the 2 groups were minimal. The second trial demonstrated no statistically significant differences in the pharmacokinetics of bupropion and its active metabolites in 9 subjects with mild to moderate hepatic cirrhosis compared to 8 healthy volunteers.

In addition, in patients with severe hepatic cirrhosis, the bupropion Cmax and AUC were substantially increased mean difference: Left Ventricular Dysfunction During a chronic dosing study with bupropion in 14 depressed patients with left ventricular dysfunction history of CHF or an enlarged heart on x-ray , there was no apparent effect on the pharmacokinetics of bupropion or its metabolites, compared to healthy volunteers.

A single-dose pharmacokinetic study demonstrated that the disposition of bupropion and its metabolites in elderly subjects was similar to that in younger subjects. These data suggest that there is no prominent effect of age on bupropion concentration; however, another single-and multiple-dose pharmacokinetic study suggested that the elderly are at increased risk for accumulation of bupropion and its metabolites [see Use in Specific Populations ].

Gender A single-dose study involving 12 healthy male and 12 healthy female volunteers revealed no sex-related differences in the pharmacokinetic parameters of bupropion. In addition, pooled analysis of bupropion pharmacokinetic data from 90 healthy male and 90 healthy female volunteers revealed no sex-related differences in the peak plasma concentrations of bupropion. Smokers The effects of cigarette smoking on the pharmacokinetics of bupropion hydrochloride were studied in 34 healthy male and female volunteers; 17 were chronic cigarette smokers and 17 were nonsmokers.

Following oral administration of a single mg dose of bupropion, there was no statistically significant difference in Cmax, half-life, Tmax, AUC, or clearance of bupropion or its active metabolites between smokers and nonsmokers.

In addition, in vitro studies suggest that paroxetine, sertraline, norfluoxetine, fluvoxamine, and nelfinavir inhibit the hydroxylation of bupropion. The exposures of hydroxybupropion were decreased. Following oral administration of bupropion mg with and without cimetidine mg in 24 healthy young male volunteers, the pharmacokinetics of bupropion and hydroxybupropion were unaffected. Citalopram did not affect the pharmacokinetics of bupropion and its three metabolites.

While not systematically studied, these drugs may induce the metabolism of bupropion. In a study of 8 healthy male volunteers, following a day administration of bupropion mg three times per day, there was no evidence of induction of its own metabolism.

Nevertheless, there may be the potential for clinically important alterations of blood levels of coadministered drugs. The effect was present for at least 7 days after the last dose of bupropion. Concomitant use of bupropion with other drugs metabolized by CYP2D6 has not been formally studied. Multiple oral doses of bupropion had no statistically significant effects on the single-dose pharmacokinetics of lamotrigine in 12 healthy volunteers.

Clinical Studies Major Depressive Disorder The efficacy of bupropion in the treatment of major depressive disorder was established with the immediate-release formulation of bupropion hydrochloride in two 4-week, placebo-controlled trials in adult inpatients with MDD and in one 6-week, placebo-controlled trial in adult outpatients with MDD. The second study included 2 fixed doses of bupropion mg and mg per day and placebo. This trial demonstrated the efficacy of bupropion for only the mg dose. In the third study, outpatients were treated with bupropion mg per day.

A longer-term, placebo-controlled, randomized withdrawal trial demonstrated the efficacy of bupropion HCl sustained-release in the maintenance treatment of MDD. The trial included adult outpatients meeting DSM-IV criteria for MDD, recurrent type, who had responded during an 8-week open-label trial of bupropion mg per day. Responders were randomized to continuation of bupropion mg per day or placebo for up to 44 weeks of observation for relapse.

Response during the open-label phase was defined as a CGI-Improvement Scale score of 1 very much improved or 2 much improved for each of the final 3 weeks. Relapse during the double-blind phase was defined as the investigator's judgment that drug treatment was needed for worsening depressive symptoms. Patients in the bupropion group experienced significantly lower relapse rates over the subsequent 44 weeks compared to those in the placebo group.

The primary efficacy endpoint was the onset of a seasonal major depressive episode. The criteria for defining an episode included: The primary analysis was a comparison of depression-free rates between the bupropion and placebo groups. In these 3 trials, the percentage of patients who were depression-free did not have an episode of MDD at the end of treatment was significantly higher in the bupropion group than in the placebo group: More What is bupropion?

Bupropion is an antidepressant medication used to treat major depressive disorder and seasonal affective disorder. The Zyban brand of bupropion is used to help people stop smoking by reducing cravings and other withdrawal effects. Bupropion may also be used for purposes not listed in this medication guide.
