Applications in medicine

Bupropion HCL can be used to treat a number of conditions, including smoking cessation, depression and obesity. Bupropion helps with seasonal affective disorder and major depressive disorder by restoring the balance of chemicals in the brain and helping the patient take control of their symptoms. It is also prescribed to help people quit smoking by reducing nicotine cravings and acting on the brain centers responsible for the urge to smoke. Because of these effects, bupropion is also used to treat patients with obesity problems because it shuts down the brain circuits responsible for overeating, so the patient can eat less without suffering from the usual amount of food.

Bupropion is available in two dosages: Bupropion 150 mg and Bupropion 300 mg. The dose you should take will be determined based on your individual needs, as well as the presence of certain medical conditions and medications you may be taking at the time.

Side effects

Mild side effects of bupropion include sleep problems, dry mouth, skin rashes, mild itching, constipation, migraine, headache, changes in appetite, nausea, weight loss, dizziness and increased sweating. They usually go away on their own. Serious side effects of Bupropion such as seizures, general malaise, concentration problems, severe blisters, swollen glands, rashes or itching, unusual thoughts or behavior, or hallucinations should be reported to your doctor immediately.

Interactions

Bupropion is mainly metabolized to hydroxybupropion by CYP2B6. Thus, there is the possibility of drugs that are CYP2B6 inhibitors or inducers and drug interactions between ZYBAN.

CYP2B6 inhibitors

Ticlopidine and Clopidogrel: The effects of bupropion may increase but decrease the effects of hydroxybupropion. Depending on the clinical response, the dosage of ZYBAN may need to be changed when co-administered with CYP2B6 inhibitors (e.g., Ticlopidine or clopidogrel).

CYP2B6 inducers

Ritonavir, Efavirenz, and Lopinavir: the effects of bupropion and hydroxybupropion may be reduced. When co-administered with efavirenz, ritonavir, lopinavir [see the. CLINICAL PHARMACOLOGY] it may be necessary to increase the dose of ZIBAN, but it should not exceed the most recommended dose. Phenobarbital, carbamazepine, phenytoin: Although no systematic studies have been conducted, these drugs may induce bupropion metabolism and reduce bupropion exposure [see. CLINICAL PHARMACOLOGY]. If bupropion can be used with a CYP inducer, the dose of bupropion may need to be increased, but the maximum recommended dose should not be exceeded.

Other drugs that should be changed

Drugs metabolized by CYP2D6 Bupropion and its metabolites (erythrohydrobupropion, triohydrobupropion, hydroxybupropion) are CYP2D6 inhibitors. Thus, co-administration of ZYBAN with drugs that are metabolized by CYP2D6 may increase the exposure of drugs that are substrates of CYP2D6. These drugs include some 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). Dose reduction of CYP2D6 substrates may be required, especially for drugs that have a narrow therapeutic index when used with ZIBAN. Drugs that require metabolic activation of CYP2D6 to be successful (e.g.g., tamoxifen) can theoretically reduce efficacy when taken concomitantly with CYP2D6 inhibitors such as bupropion. Patients treated with these drugs and ZIBAN may require increased doses of the drug.

Drugs that lower seizure threshold

Use extreme caution when co-administering ZYBAN with other drugs that lower the seizure threshold (e.g., bupropion).g., other bupropion medications, antipsychotics, antidepressants, theophylline, or systemic corticosteroids). Increase the dose slowly and use low starting doses.

Dopaminergic drugs (levodopa and amantadine)

Bupropion, levodopa, and amantadine have dopamine agonist effects. CNS toxicity continues to be reported when bupropion is coadministered with levodopa or amantadine. Side effects include agitation, restlessness, tremors, ataxia, gait disturbance, dizziness, and lightheadedness. Toxicity is thought to result from the cumulative effect of dopamine agonists. Use caution when prescribing ZIBAN with one of these drugs.

Use with alcohol

In post-marketing experience, there have been rare reports of adverse neuropsychiatric events or decreased tolerance to alcohol in patients who have used alcohol. Alcohol intake during treatment with ZYBAN should be minimized or avoided.

MAO inhibitors

Bupropion inhibits norepinephrine and dopamine reuptake. While bupropion can be used with MAOIs, due to the increased risk of hypertensive reactions, concomitant use of bupropion and MAOIs is contraindicated. Animal studies have shown that the acute toxicity of bupropion is enhanced by the MAO inhibitor phenelzine. Must allow at least 14 days between stopping MAOIs and starting treatment. After you stop taking ZYBAN, you must wait at least 14 days before starting an MAOI for mental health treatment.

Drug interactions with laboratory tests

False-positive urine immunoassay screening tests for amphetamines have been reported in patients. This may be due to lack of specificity in some screening tests. False positive assessment results are possible after discontinuation of bupropion treatment. Confirmatory tests such as gas chromatography/mass spectrometry will identify amphetamines and bupropion.

Smoking cessation

Physical changes caused by smoking cessation, with or without treatment with ZIBAN, may alter the pharmacokinetics or pharmacodynamics of certain drugs (e.g., Theophylline, warfarin, insulin), which may require dose adjustments.

Cautions when taking bupropion during pregnancy

The manufacturer recommends using bupropion during pregnancy only if the potential benefit outweighs the possible danger to the fetus. During pregnancy, it is recommended that non-drug smoking be avoided. AU TGA pregnancy category: B2 US FDA pregnancy category: C High-dose animal studies showed no evidence of teratogenic effects, which has been a particular. In animal studies at low doses in rabbits, a slight increase in the incidence of skeletal abnormalities and fetal malformations has been reported. Epidemiologic studies of pregnant women exposed to bupropion in the first trimester found no increased risk of congenital malformations complete. International bupropion pregnancy registry data (675 first-trimester exposures), as well as a retrospective cohort study using the United Healthcare database (1,213 first-trimester exposures) and a case-control study of the National Birth Defects Prevention Study (6,853 children with cardiovascular malformations and 5,763 children with noncardiovascular malformations) showed no increased risk for malformations after bupropion exposure. A retrospective database of infants (n=7005) whose mothers took bupropion during the first trimester and after the first trimester also showed no increased risk of birth defects, especially cardiovascular defects. The results of studies on the dangers of interventricular septal defect and left ventricular outflow tract obstruction after bupropion administration in the first trimester of pregnancy are inconclusive. AU TGA pregnancy category B2: Drugs taken by a small number of girls as well as pregnant girls of childbearing age, with no evidence of increased incidence of malformations or other direct or indirect harmful effects on the human fetus. Animal studies may be lacking or insufficient, but available data show no evidence of an increased incidence of fetal injury. US FDA pregnancy category C: animal reproduction studies have shown adverse effects, and adequate and well-controlled human studies are not available, but potential benefits may justify use in pregnant women despite potential dangers.

Warnings on the use of bupropion in breastfeeding

There is reliable information that bupropion taken by the mother in oral doses of up to 300 milligrams per day is excreted into breast milk in negligible amounts. It is generally assumed not to cause adverse effects in breastfed infants; however, there are reports of possible seizures in 6-month-old partially breastfed infants. Alternative drugs to be considered in place of bupropion include sertraline, paroxetine, and nortriptyline. One case has shown that bupropion accumulates in human breast milk at concentrations significantly higher than maternal plasma concentrations. At least two metabolites of bupropion were also found in human milk. However, bupropion and its metabolites were detected in the plasma of only one nursing infant whose mother was taking bupropion. Lactation study data from 10 girls showed that the amount of the drug in breast milk was 45.2 µg/L for bupropion, and 104.6 µg/ml, 72.1 µg/mL and 459 µg/mL for its metabolites hydroxybupropion, erythrohydroxybupropion, and triohydroxybupropion, respectively. The authors of this study estimated that an exclusively breastfed baby would get an average of 0.2% of the maternal weight-adjusted dose of bupropion and an average of 2% of the maternal weight-adjusted dose of bupropion plus metabolites. Use with caution; a choice must be made between stopping breastfeeding and discontinuing the drug, considering the benefits of breastfeeding to the mother and child and the need for the drug. Another drug may be chosen, especially when breastfeeding a premature or newborn infant. Excreted in human milk: Yes.
