Zyban SR (Bupropion)

A Proven Aid to Support Smoking Cessation and Improve Mood

Zyban SR contains Bupropion hydrochloride, a unique prescription drug used to help adults stop smoking. The antidepressant qualities of this medication are also well-known. It’s prescribed for depression, anxiety, and other disorders under various brand names.

Zyban works by targeting neurotransmitters to decrease nicotine cravings, withdrawal symptoms, and increase the chance of quitting smoking. This formulation is a sustained-release formula (SR), which allows for easy twice-daily dosage and constant blood levels. It improves patient compliance and enhances therapeutic effects.

Active Ingredient

• Bupropion hydrochloride sustained release — 150 mg per tablet

Bupropion can be classified as an atypical antidepressant and a smoking cessation drug. Bupropion affects the neurotransmitters norepinephrine and dopamine, both of which play a role in regulating mood and addiction.

Indications

• Smoking cessation aid: Zyban SR is approved for adults to stop smoking. It reduces nicotine withdrawal symptoms, such as anxiety, irritability, cravings, and difficulty concentrating.
• Adjunct in depression treatment: Bupropion, marketed under the name Wellbutrin, is a mood-improvement drug that can be beneficial to patients who are quitting smoking and may have depressive symptoms.

How Zyban SR Works

Nicotine addiction causes changes in the brain’s chemistry. It affects dopamine receptors, which are responsible for reward and pleasure. The sudden absence of nicotine can cause withdrawal symptoms and lead to a relapse when a smoker quits.

Bupropion works by blocking the reuptake of dopamine and norepinephrine neurotransmitters, which influence moods and reward systems. The action of bupropion helps to reduce withdrawal symptoms and the desire to smoke.

Dosage and Administration

Typical adult dosing for smoking cessation:

• Begin treatment one to two weeks before your planned quitting date.
• Start by taking 150mg once per day for 3 days.
• From day 4, increase to 150 mg twice daily in the morning and early afternoon.
• Follow your doctor’s advice and continue treatment until 7 to 12 weeks, or for as long as you are advised.
