Nordobux Sandoz (Bupropion Hydrochloride)

Bupropion hydrochloride is employed in the management of mood disorders and nicotine dependence, acting on the central norepinephrine‑dopamine system. It is prescribed when other antidepressants are unsuitable or when a dual action on norepinephrine and dopamine is desired.

• Major depressive disorder: reduces depressive symptoms, improves energy and concentration in adults.
• Seasonal affective disorder: mitigates depressive episodes linked to seasonal changes, enhancing mood during winter months.
• Smoking cessation: lessens nicotine cravings and withdrawal, supporting quit attempts in adult smokers.

• Bupropion hydrochloride inhibits the neuronal reuptake of norepinephrine and dopamine by binding to their transporters, leading to increased synaptic concentrations of these neurotransmitters. The elevated catecholamine activity enhances neurotransmission in brain regions involved in mood regulation and reward, which underlies its antidepressant and anti‑nicotine‑craving effects. It does not significantly affect serotonin pathways, distinguishing it from many other antidepressants.

Bupropion hydrochloride may cause a range of adverse reactions, varying from mild to serious.

Common Side Effects

• Insomnia: difficulty falling or staying asleep.
• Dry mouth: reduced salivation.
• Headache: mild to moderate pain.
• Nausea: upset stomach.
• Tremor: fine shaking of the hands.

Serious or Rare Side Effects

• Seizures: risk increases at higher doses.
• Hypertensive crisis: sudden high blood pressure.
• Severe allergic reaction: rash, swelling, or breathing difficulty.

When prescribing bupropion hydrochloride, clinicians should consider several safety precautions to minimize risks.

• Assess seizure risk: evaluate history of seizures, eating disorders, or abrupt alcohol withdrawal.
• Monitor blood pressure: check for hypertension, especially in patients with cardiovascular disease.
• Review psychiatric status: watch for worsening depression or emergence of suicidal thoughts.
• Avoid concomitant MAO inhibitors: ensure a 14‑day washout period when switching.
• Caution in pregnancy: use only if benefits outweigh potential risks (Category B).
• Store at ambient temperature: keep below 25 °C in original container, protect from moisture.

Bupropion hydrochloride can interact with several medications, altering its efficacy or safety profile.

Major Interactions (Avoid)

• Monoamine oxidase inhibitors (MAOIs): risk of hypertensive crisis.
• CYP2B6 inhibitors (e.g., clopidogrel): increase bupropion levels, raising seizure risk.
• Other NDRIs or stimulant agents: additive seizure potential.

Moderate Interactions (Monitor Closely)

• CYP2B6 inducers (e.g., rifampin): may reduce bupropion effectiveness.
• Antidepressants affecting serotonin (e.g., SSRIs): monitor for serotonin syndrome signs.
• Antipsychotics (e.g., haloperidol): may increase plasma concentrations.
