Generic Bupropion Information

Introduction

Bupropion (hydrochloride) is an antidepressant medication classified within the atypical antidepressant group. It is widely prescribed in Hong Kong for major depressive disorder and as an aid to quit smoking. The active compound, Bupropion Hydrochloride, acts on central neurotransmitters to improve mood and reduce nicotine cravings. Several multinational manufacturers produce the drug, and it is also available in well‑known brand formulations such as Wellbutrin® (depression) and Zyban® (smoking cessation). In addition to these primary indications, clinicians occasionally use Bupropion for off‑label conditions such as attention‑deficit/hyperactivity disorder (ADHD) and seasonal affective disorder, when supported by clinical judgement.

What is Bupropion?

Bupropion is the generic name for a medication whose active ingredient is Bupropion Hydrochloride. It belongs to the class of atypical antidepressants because its pharmacological profile differs from classic serotonin‑reuptake inhibitors. The drug was first synthesized by Burroughs Wellcome (now GlaxoSmithKline) in the early 197s and received regulatory approval in the United States in 1985. In Hong Kong, the medication is registered under the Pharmacy and Poisons Ordinance and can be dispensed only with a doctor’s prescription.

Bupropion is the generic version of the original brand Wellbutrin® (depression) and Zyban® (smoking cessation). Our online pharmacy provides this generic alternative as a cost‑effective treatment option for qualified patients.

How Bupropion Works

Bupropion’s primary mechanism is inhibition of the neuronal reuptake of norepinephrine and dopamine. By blocking the transporters for these catecholamines, synaptic concentrations increase, leading to enhanced stimulation of downstream pathways that regulate mood, motivation, and reward.

Key pharmacodynamic points:

• Dopamine elevation reduces anhedonia and mitigates nicotine‑induced dopamine deficits, which explains its utility in smoking cessation.
• Norepinephrine potentiation improves alertness and counteracts depressive lethargy.

Pharmacokinetic characteristics relevant to therapy:

• Onset of therapeutic effect: Typically 2–4 weeks for depression; craving reduction may be noticeable within the first week for smoking cessation.
• Half‑life: Approximately 21 hours for the parent compound; active metabolites (hydroxy‑bupropion) have a half‑life of 30 — 40 hours, supporting once‑ or twice‑daily dosing.
• Metabolism: Hepatic cytochrome P450 2B6 is the principal enzyme; inhibitors or inducers of this pathway can alter plasma levels.

The combined neurotransmitter actions produce an antidepressant effect while preserving sexual function and causing less weight gain compared with many serotonergic agents.

Conditions Treated with Bupropion

• Major Depressive Disorder (MDD): Approved by the Hong Kong Department of Health for adult patients with moderate to severe depression. Clinical trials show response rates comparable to selective serotonin reuptake inhibitors (SSRIs) with a lower incidence of sexual dysfunction.
• Smoking Cessation: Marketed as Zyban® for reducing nicotine withdrawal symptoms. The Hong Kong Centre for Health Protection advocates Bupropion as a first‑line pharmacotherapy when behavioural support is also provided.
• Seasonal Affective Disorder (SAD): Often used off‑label because of its dopaminergic activity, which counters winter‑related low mood.
• Attention‑Deficit/Hyperactivity Disorder (ADHD) in adults: Some psychiatrists prescribe Bupropion when stimulants are contraindications, based on modest improvements in attention and impulse control.

Epidemiological context: Depression affects roughly 5 % of Hong Kong adults, and smoking prevalence remains at about 13 % among men. The availability of a single medication addressing both conditions simplifies treatment pathways for patients with comorbid depression and nicotine dependence.

Patient Groups Most Likely to Benefit

• Adults with MDD who experience sexual side effects from SSRIs or who have weight‑gain concerns.
• Smokers motivated to quit who have a history of depressive symptoms, because Bupropion treats both simultaneously.
• Patients with partial response to serotonergic antidepressants, where a switch to a norepinephrine‑dopamine agent may improve outcomes.
• Individuals with a history of seizures must avoid Bupropion, but patients with controlled epilepsy at low seizure risk may still be considered after specialist review.

Contra‑indicated or cautionary groups:

• Patients with active eating disorders (due to seizure threshold), recent seizure episodes, or abrupt discontinuation of alcohol or sedatives.
• Pregnant or breastfeeding women—use only if the potential benefit outweighs the unknown fetal risk.
• Individuals receiving monoamine oxidase‑inhibitors (MAOIs) within 14 days, as the combination can precipitate hypertensive crises.

Risks, Side Effects, and Interactions

Common

• Insomnia – may be mitigated by taking the dose in the morning.
• Dry mouth – encourage regular sips of water and sugar‑free gum.
• Headache – usually mild; acetaminophen is acceptable if needed.
• Nausea or gastrointestinal upset – often transient during the first week.
• Sweating – peripheral hyperhidrosis reported in up to 10 % of users.

Rare

• Tremor – dose reduction or slower titration may help.
• Weight loss – generally modest; monitor nutritional status in underweight patients.
• Skin rash or pruritus – discontinue if severe hypersensitivity develops.

Serious

• Seizure – risk increases with doses >450 mg/day, rapid dose escalation, or pre‑existing seizure disorders. Immediate medical attention required.
• Suicidal ideation – as with all antidepressants, monitor closely during the first few weeks, especially in younger adults.
• Hypertensive crisis – possible when combined with MAOIs or sympathomimetic agents. Blood pressure elevation may be abrupt and requires emergency care.

Clinically Relevant Drug–Drug Interactions

• CYP2B6 inhibitors (e.g., clopidogrel, ritonavir) → increase Bupropion plasma concentrations, heightening seizure risk.
• CYP2B6 inducers (e.g., carbamazepine, phenytoin) → reduce efficacy, may necessitate dose adjustment.
• Other central stimulants (e.g., methylphenidate) → additive increase in blood pressure and seizure propensity.
• Monoamine oxidase inhibitors – must be separated by at least 14 days.
• Alcohol – concurrent use lowers seizure threshold; patients should limit intake.

Patients should disclose all prescription, over‑the‑counter, and herbal products before initiating therapy.

Practical Use: Dosing, Missed Dose, Overdose

Standard adult dosing for depression (tablet formulations):

• Initiate with 150 mg once daily in the morning.
• After 3–4 days, increase to 300 mg once daily (as a single dose) or 150 mg twice daily (morning and early afternoon).
• Maximum recommended dose: 450 mg per day (split as 150 mg three times).

Smoking cessation regimen (extended‑release tablets):

• Days 1–7: 150 mg once daily (preferably morning).
• Day 8 onward: 150 mg twice daily (morning and early afternoon) for 7‑12 weeks.

Missed dose:

• If the missed dose is discovered within 8 hours, take it immediately.
• If more than 8 hours have passed, skip the missed dose and resume the regular schedule. Do not double‑dose.

Overdose management:

• Signs may include seizures, tachycardia, hypertension, agitation, or coma.
• Immediate medical attention is essential; emergency services should be contacted (HK emergency number 999).
• Activated charcoal may be administered if presentation is within one hour of ingestion, under medical supervision.

Practical precautions:

• Take tablets with a full glass of water; avoid taking the dose within  4 hours of bedtime to reduce insomnia.
• Alcohol consumption should be limited; chronic heavy drinking markedly raises seizure risk.
• Patients with hepatic impairment may require lower starting doses and slower titration.
• Renal dysfunction does not markedly affect clearance, but monitoring is advised in severe disease.

Regular follow‑up visits (every 2–4 weeks initially) allow dose titration, efficacy assessment, and safety monitoring.

Glossary

Cytochrome P450 2B6

An enzyme in the liver that metabolises Bupropion. Inhibitors can raise drug levels, while inducers can lower them.

Extended‑Release (XL)

A formulation that releases the active ingredient slowly over time, allowing once‑ or twice‑daily dosing and smoother plasma concentrations.

Seizure Threshold

The level of neuronal excitability at which a seizure may occur. Certain drugs, including high doses of Bupropion, can lower this threshold.

Monoamine Oxidase Inhibitor (MAOI)

A class of antidepressants that prevent the breakdown of monoamines. Combining MAOIs with Bupropion can precipitate hypertensive emergencies and is therefore contraindicated.
