Zyban SR (Bupropion)

Zyban SR (Bupropion) is a sustained-release oral medication that belongs to the class of antidepressants known as norepinephrine-dopamine reuptake inhibitors (NDRIs). It is primarily prescribed as a smoking cessation aid and helps reduce cravings and withdrawal symptoms associated with nicotine dependence. Unlike nicotine replacement therapies, Zyban SR does not contain nicotine; instead, it works on brain neurotransmitters (dopamine and norepinephrine) to reduce the urge to smoke.

The medication is usually started 1–2 weeks before the target quit date and continued for 7–12 weeks or as advised by a healthcare professional. In addition to its role in smoking cessation, Bupropion is also prescribed under other brand names for depression and seasonal affective disorder (SAD).

Key Benefits:

• Helps reduce nicotine cravings and withdrawal effects

Important Notes:

• Zyban SR is available only with a doctor’s prescription.

• It may cause side effects such as insomnia, dry mouth, or dizziness.
