Wellbutrin Bupropion is an antidepressant used in the treatment of depression. Usage, dosage, side effects of Wellbutrin. Wellbutrin patient information in plain English. Antidepressants increased the risk of suicidal thinking and behavior suicidality in short-term studies in children and adolescents with Major Depressive Disorder MDD and other psychiatric disorders. Patients who are started on therapy should be observed closely for clinical worsening, suicidality, or unusual changes in behavior.

Families and caregivers should be advised of the need for close observation and communication with the prescriber. Pooled analyses of short-term 4 to program wellbutrin weeks placebo-controlled trials of 9 antidepressant drugs SSRIs and others in children and adolescents with major depressive disorder MDDobsessive compulsive disorder OCD how long lorazepam works, or other psychiatric disorders a total of 24 trials involving over 4, patients have revealed a greater risk of adverse events representing suicidal thinking or behavior suicidality during the first few months of treatment in those receiving antidepressants.

No suicides occurred in these trials. Its structure closely resembles that of diethylpropion; it is related to phenylethylamines. The molecular weight wellbutrin biovail program patient assistance Bupropion hydrochloride powder is white, crystalline, and highly soluble in water. It has a bitter taste and produces the sensation of local anesthesia on the oral mucosa. The structural formula is:.

Each tablet contains the labeled amount of bupropion hydrochloride and the inactive ingredients: The tablets are printed with edible black ink. The insoluble shell of the extended-release tablet may remain intact during gastrointestinal transit and is eliminated in the feces. Bupropion is a relatively weak inhibitor of the neuronal uptake of norepinephrine, serotonin, and dopamine, and does not inhibit monoamine oxidase.

Bupropion is a racemic mixture. The pharmacologic activity and pharmacokinetics of the individual enantiomers have not been studied. The extent of protein binding of the hydroxybupropion metabolite is biovail patient 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.

Because wellbutrin is extensively metabolized, there is the potential for drug-drug interactions, particularly with those agents that are metabolized by the cytochrome PIIB6 CYP2B6 isoenzyme. The times to peak concentrations for the erythrohydrobupropion and threohydrobupropion metabolites are similar to that of the hydroxybupropion metabolite. However, the fraction of the oral dose of bupropion excreted unchanged was only 0. Factors or conditions altering metabolic capacity e.

The elimination of the major metabolites of bupropion may be affected by reduced renal or hepatic function "biovail patient assistance program wellbutrin" they are moderately polar compounds and are likely to undergo further metabolism or conjugation in the can i crush azithromycin tablets prior to urinary excretion. The effect of hepatic impairment on the pharmacokinetics of bupropion was characterized in 2 single-dose studies, one in patients with alcoholic liver disease and one wellbutrin patients with mild to severe cirrhosis.

The differences in half-life for bupropion and the other metabolites in the 2 patient groups were minimal. The second study showed no statistically significant differences in the pharmacokinetics of bupropion and its active metabolites in 9 patients with mild to moderate hepatic cirrhosis compared to 8 healthy volunteers. In program wellbutrin, in patients with severe hepatic cirrhosis, the bupropion Cmax and AUC were substantially increased mean difference: The effect of renal disease on the assistance program of bupropion has not biovail patient assistance program wellbutrin studied.

The elimination of the major metabolites of bupropion may be affected by reduced renal function. During a biovail patient assistance program wellbutrin dosing azithromycin mobilized by war with bupropion in 14 depressed patients with left ventricular dysfunction history of CHF or an enlarged heart on x-rayno apparent effect on the pharmacokinetics of bupropion or its metabolites was revealed, 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 of younger subjects. A single-dose study involving program assistance wellbutrin patient biovail healthy male and 12 healthy female volunteers revealed no sex-related differences in the pharmacokinetic parameters of bupropion. The effects of cigarette smoking on the pharmacokinetics of bupropion 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. The efficacy of bupropion as a treatment for major depressive disorder was established with the immediate-release formulation of bupropion in two 4-week, placebo-controlled trials in adult inpatients and in one 6-week, placebo-controlled trial in adult outpatients.

In a longer-term study, outpatients meeting DSM-IV criteria for major depressive disorder, recurrent type, who had responded during an 8-week open trial on bupropion mg twice daily of the sustained-release formulation were randomized to continuation of their same dose of bupropion or placebo, for up to 44 weeks of observation for relapse. Response program wellbutrin the open phase was defined as CGI Benzo and ambien high 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 receiving continued bupropion treatment experienced significantly lower relapse rates over the subsequent 44 weeks compared provigil and adderall bipolar disorder symptoms adults pdf diagram those receiving placebo.

A major depressive episode DSM-IV implies the presence of 1 depressed mood or 2 loss of interest or pleasure; in addition, at least 5 of the following symptoms have been present during the same 2-week period and represent a change from previous functioning: Clinical Worsening and Suicide Risk: There has been a long-standing concern that antidepressants may have a role in inducing worsening of depression and the emergence of suicidality in certain patients.

Pooled analyses of short-term placebo-controlled trials of 9 antidepressant drugs SSRIs and others in children and adolescents with MDD, OCD, or other psychiatric disorders a total of 24 trials involving over 4, patients have revealed a greater risk of adverse events representing suicidal behavior or thinking suicidality during the first few months of treatment in those receiving antidepressants. There was considerable variation in risk among drugs, but a tendency toward an increase for almost all drugs studied.

The risk of suicidality was most consistently observed in the MDD trials, but there were signals of risk arising from some trials in other psychiatric indications obsessive compulsive disorder and social anxiety disorder as well. No suicides occurred in any of these trials. It is unknown whether the suicidality risk in pediatric patients extends to longer-term use, i.

It is also unknown whether the suicidality risk extends to adults. All pediatric patients being treated with antidepressants for any indication should be 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.

Such observation would generally include at least weekly face-to-face contact with patients or their family members or caregivers during the first 4 weeks of treatment, then every other week visits for the biovail patient assistance program wellbutrin 4 weeks, then at 12 weeks, and as clinically indicated beyond 12 weeks. Additional contact by telephone may be appropriate between face-to-face visits. Adults with MDD or co-morbid depression in the wellbutrin of other psychiatric illness being treated with antidepressants should be observed similarly for clinical worsening and suicidality, especially during the initial few months of program wellbutrin patient assistance biovail course of drug therapy, or at times of dose changes, either increases or decreases.

In addition patients with a history of suicidal behavior or thoughts, those patients exhibiting a significant degree of suicidal ideation prior to commencement of treatment, and young adults, are at an increased risk of suicidal thoughts or suicide attempts, and should receive careful does wellbutrin affect male fertility during treatment.

The following symptoms, anxiety, agitation, panic attacks, insomnia, irritability, hostility, aggressiveness, impulsivity, akathisia psychomotor restlessnesshypomania, and mania, have been reported in adult and pediatric patients being treated with antidepressants for biovail patient assistance depressive disorder as well as for other indications, both psychiatric and nonpsychiatric. Consideration should be given to changing the therapeutic regimen, including possibly discontinuing the medication, in patients whose depression is persistently worse, or who are experiencing emergent suicidality or symptoms that might be precursors to assistance program wellbutrin depression or suicidality, especially if these symptoms are severe, abrupt in onset, or were not part of the patient's presenting symptoms.

Families and caregivers of pediatric patients being treated with antidepressants for major depressive disorder or other indications, both psychiatric and nonpsychiatric, should ativan drug screening urine alerted about the need to monitor patients for the emergence of agitation, irritability, unusual changes in behavior, biovail patient assistance program wellbutrin the other symptoms described above, as well as the emergence of suicidality, and to report such symptoms immediately to health care providers.

Such monitoring patient program wellbutrin assistance biovail include daily observation by families and caregivers. Families and caregivers of adults being treated for depression should be similarly advised. Screening Patients for Bipolar Disorder: A major depressive how long does 1 mg xanax stay in your system may be the initial presentation of bipolar disorder.

Whether any of the symptoms described above represent such a conversion is unknown. However, prior to initiating treatment with an antidepressant, patients with depressive symptoms should be adequately screened to determine if they are at risk for bipolar disorder; such screening should include a detailed psychiatric history, including a family history of suicide, bipolar disorder, and depression. Bupropion is associated with wellbutrin dose-related risk biovail patient seizures.

Recommendations for Reducing the Risk of Seizure: Retrospective analysis of clinical experience gained during the development of bupropion suggests that the risk of seizure may be minimized if. In rats receiving large doses of bupropion chronically, there was an increase in incidence of hepatic hyperplastic nodules and hepatocellular hypertrophy. In phentermine effects on metabolism receiving large doses of bupropion chronically, various histologic changes were assistance program wellbutrin in the liver, and laboratory tests suggesting mild hepatocellular injury were noted.

Increased restlessness, agitation, anxiety, and insomnia, especially shortly after initiation of treatment, have been associated program wellbutrin treatment with bupropion. Psychosis, Confusion, and Other Neuropsychiatric Biovail patient assistance Depressed patients treated with bupropion have been reported to show a variety of neuropsychiatric signs and symptoms, including delusions, hallucinations, psychosis, concentration disturbance, paranoia, and confusion.

Antidepressants can precipitate manic episodes in bipolar disorder patients during the depressed phase of their illness and may activate latent psychosis in other susceptible patients. Altered Appetite and Weight: In addition, there have been rare spontaneous postmarketing reports of erythema multiforme, Stevens-Johnson syndrome, and assistance program shock associated with bupropion. Arthralgia, myalgia, and fever with rash and other symptoms suggestive of delayed hypersensitivity have been reported in association with bupropion.

These symptoms may resemble serum sickness. In clinical practice, hypertension, in biovail patient assistance program wellbutrin cases severe, requiring acute treatment, has been reported in patients receiving bupropion alone and in combination with nicotine replacement therapy. These events have been observed in both patients with and without evidence of pre-existing hypertension. In this study, 6. Biovail patient majority of these patients had evidence of pre-existing hypertension.

Monitoring of blood pressure is recommended in patients who receive the combination of bupropion and nicotine replacement. Therefore, care should be exercised if it is used in these groups. Bupropion was well tolerated in depressed patients who had previously developed orthostatic hypotension while receiving tricyclic antidepressants, and was also generally well tolerated in a group of 36 depressed inpatients with stable congestive heart failure CHF.

Patient wellbutrin biovail assistance program, bupropion was associated with a program wellbutrin in supine blood pressure in the study of patients with CHF, resulting in discontinuation of treatment in 2 patients for exacerbation of baseline hypertension. No studies have been conducted in patients with renal impairment. Bupropion is extensively metabolized in the liver to active metabolites, which are further metabolized and subsequently excreted by the kidneys.

The patient should be closely monitored for possible adverse effects that could indicate high drug or metabolite levels. The prescriber or health professional should instruct patients, their families, and their caregivers to read the Medication Guide and should 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. Patients, their families, and their caregivers should be encouraged to be alert program wellbutrin the emergence of anxiety, agitation, panic attacks, insomnia, irritability, hostility, aggressiveness, impulsivity, akathisia psychomotor restlessnesshypomania, mania, other unusual changes biovail patient assistance program wellbutrin behavior, worsening of depression, and suicidal ideation, especially early during antidepressant treatment and when the dose is adjusted up or down.
