Bupropion HCL can be used for a number of medical conditions, including smoking cessation, depression and obesity. Bupropion works for seasonal affective disorder and major depressive disorder by restoring the balance of chemicals in the brain and helping the patient take control over their symptoms. It’s also prescribed to help people stop smoking by reducing nicotine cravings and affecting brain centers responsible for the urges. Because of those effects, Bupropion is also used for patients with obesity problem, as it switches off the brain circuits responsible for overeating, that way making sure the patient can eat less without suffering without the amount of food they are accustomed to.

Dosage and directions
Bupropion comes in two dosages: Bupropion 150 mg and Bupropion 300 mg. The dose you have to be taking will be determined based on the individual needs you have, as well as presence of certain medical conditions and drugs you may be taking at the moment.
Mild side effects of Bupropion include sleep problems, dry mouth, skin rash, mild itching, constipation, migraine, headache, appetite changes, nausea, weight loss, dizziness and increased sweating. Usually they go away on their own.

Bupropion is mainly metabolized to hydroxybupropion by CYP2B6. Thus, the possibility exists for drugs which are inhibitors or inducers of CYP2B6 and drug interactions between ZYBAN.
Inhibitors Of CYP2B6
Ticlopidine and Clopidogrel: Bupropion exposure cans raise but reduce hydroxybupropion exposure. According to clinical response, dosage alteration of ZYBAN might be needed when coadministered with CYP2B6 inhibitors (e.g., ticlopidine or clopidogrel).
Inducers Of CYP2B6
Ritonavir, Efavirenz, and Lopinavir: Bupropion and hydroxybupropion exposure cans reduce. Dosage increase of ZYBAN might be needed when coadministered with efavirenz, or ritonavir, lopinavir [see CLINICAL PHARMACOLOGY] but shouldn’t surpass the most recommended dose.
Phenobarbital, carbamazepine, Phenytoin: While not systematically examined, these drugs may cause the metabolism of bupropion and can reduce exposure that is bupropion [see CLINICAL PHARMACOLOGY]. If bupropion can be used with a CYP inducer, it might be required to raise the dose of bupropion, but the maximum recommended dose shouldn’t be surpassed.
Other Drugs To Change
Drugs Metabolized By CYP2D6
Bupropion and its metabolites (erythrohydrobupropion, threohydrobupropion, hydroxybupropion) are CYP2D6 inhibitors. Thus, coadministration of ZYBAN with drugs which are metabolized by CYP2D6 can raise the exposures of drugs which are substrates of CYP2D6. Such drugs include certain antidepressants (e.g., venlafaxine, nortriptyline, imipramine, desipramine, paroxetine, fluoxetine, and sertraline), antipsychotics (e.g., haloperidol, risperidone, thioridazine), beta blockers (e.g., metoprolol), and Type 1C antiarrhythmics (e.g., propafenone and flecainide). It might be required to reduce the dose of the CYP2D6 substrates, especially for drugs having a narrow therapeutic index when used with ZYBAN.
Drugs that need metabolic activation by CYP2D6 to be successful (e.g., tamoxifen) theoretically could have reduced effectiveness when administered concomitantly with inhibitors of CYP2D6 such as bupropion. Patients treated with such drugs and ZYBAN may need increased doses of the drug.
Drugs That Lower Seizure Threshold
Use extreme care when coadministering ZYBAN with other drugs that lower seizure threshold (e.g., other bupropion merchandises, antipsychotics, antidepressants, theophylline, or systemic corticosteroids). Raise the dose slowly and use low initial doses.
Dopaminergic Drugs (Levodopa And Amantadine)
Bupropion, levodopa, and amantadine have dopamine agonist effects. CNS toxicity continues to be reported when bupropion was coadministered with levodopa or amantadine. Adverse reactions have included agitation, restlessness, tremor, ataxia, gait disturbance, vertigo, and dizziness. It’s presumed the toxicity results from dopamine agonist effects that were accumulative. Use care when administering ZYBAN with one of these drugs.
Use With Booze
There happen to be rare reports of adverse neuropsychiatric events or reduced alcohol tolerance in patients who have been drinking alcohol, in postmarketing experience. The ingestion of alcohol during treatment with ZYBAN must be minimized or prevented.
Bupropion inhibits the reuptake of norepinephrine and dopamine. If bupropion can be used with MAOIs, because there’s a heightened threat of hypertensive responses concomitant usage of bupropion and MAOIs is contraindicated. Studies in animals show the acute toxicity of bupropion is enhanced by the MAO inhibitor phenelzine. At least 14 days should elapse between discontinuation of an MAOI and initiation of treatment. At least 14 days needs to be allowed after discontinuing ZYBAN before starting an MAOI meant to treat psychiatric illnesses.
Drug-Laboratory Test Interactions
False positive urine immunoassay screening tests for amphetamines are reported in patients. This can be due to lack of specificity of some screening tests. Evaluation results that are falsepositive may result following discontinuation of bupropion treatment. Confirmatory tests, like gas chromatography/mass spectrometry , will recognize amphetamines and bupropion.
Physical changes caused by smoking cessation, with or without treatment with ZYBAN, may change the pharmacokinetics or pharmacodynamics of particular drugs (e.g., theophylline, warfarin, insulin) for which dosage adjustment may be required.
Bupropion Pregnancy Cautions
Producer recommends that bupropion ought to be utilized during pregnancy only when the potential benefit outweighs the possible hazard to the fetus. Smoking cessation without using drugs is advisable during pregnancy. AU TGA pregnancy category: B2 US FDA pregnancy category: C
High dose animal studies have failed to show signs of teratogenic effects that were special. Low dose animal studies in rabbits have reported a marginally increased incidence of skeletal variations and fetal malformations. Epidemiological studies of pregnant women exposed to bupropion in the first trimester demonstrate no increased danger of congenital malformations complete. Data in the international bupropion pregnancy register (675 trimester exposures) as well as a retrospective cohort study utilizing the United Healthcare database (1,213 first trimester exposures) and a case-control study from the National Birth Defects Prevention Study (6,853 babies with cardiovascular malformations and 5,763 with non-cardiovascular malformations) didn’t demonstrate an increased risk for malformations complete after bupropion exposure during the first trimester. A retrospective database of babies (n=7005) whose moms were subjected to bupropion in the first trimester and beyond the first trimester also didn’t show a heightened danger of congenital malformation, particularly cardiovascular malformation. Study findings on the danger of ventricular septal defect and left ventricular outflow tract obstruction after first trimester exposure to bupropion are inconclusive. AU TGA pregnancy category B2: Drugs that have been taken by just a small amount of girls as well as pregnant girls of childbearing age, without a rise in the frequency of malformation or other direct or indirect harmful influences on the human fetus having been detected. Studies in animals may be lacking or are inadequate, but available data show no signs of a heightened incidence of fetal damage. US FDA pregnancy category C: Animal reproduction studies have demonstrated an adverse impact and there aren’t any adequate and well-controlled studies in humans, but potential benefits may justify use of the drug in pregnant women despite potential dangers.
Bupropion Breastfeeding Warnings
There’s bound information that motherly bupropion at oral doses up to 300 milligrams daily generates low amounts in breastmilk. It isn’t normally anticipated to cause adverse effects in breastfed babies; yet, there are case reports of potential seizure in partly breastfed 6-month olds. Alternative drugs that’ll be looked at in place of bupropion contain sertraline, paroxetine, and nortriptyline. One case report has indicated that bupropion piles up in human breast milk in concentrations considerably greater than in maternal plasma. At least two metabolites of bupropion will also be detectable in human milk. Yet, in the plasma of just one nursing baby whose mother took bupropion bupropion nor its metabolites might be found. Data from a lactation study in 10 girls demonstrated breastmilk amounts of 45.2 mcg/L for bupropion, and 104.6 mcg/mL, 72.1 mcg/mL, and 459 mcg/mL for it metabolites hydroxybupropion, erythrohydroxybupropion, and threohydroxybupropion, respectively. The writers with this study estimated that an exclusively breastfed baby would receive a mean of 0.2% of the maternal weight-adjusted dose of bupropion and an average of 2% of the maternal weight-adjusted dosage of bupropion plus metabolites.
Use with caution; a choice ought to be built to discontinue nursing or discontinue the drug, considering the good thing about breastfeeding to the mother to the baby and also the need for the drug. Another drug might be chosen, especially when breastfeeding a preterm or newborn infant. Excreted into milk that was human: Yes
