Zebeta is a prescription pill that contains bisoprolol as its sole active ingredient. Bisoprolol belongs to the beta-blocker class of medicines and is used to manage conditions that involve the heart and blood pressure. In Hong Kong, Zebeta is regulated by the Department of Health and is available in 5 mg and 10 mg tablets.
Bisoprolol is a β1-selective adrenergic blocker. It binds preferentially to β1 receptors located mainly in the heart, reducing the effects of adrenaline and noradrenaline. The result is:
Because the drug targets β1 receptors specifically, it has less impact on β2 receptors found in the lungs, making it relatively safer for patients with mild respiratory conditions. The onset of action occurs within 2 hours after oral intake, with peak plasma concentrations reached at about 4 hours. Its half-life is roughly 10-12 hours, allowing once-daily dosing.
Zebeta is FDA- and EMA-approved for the following indications, which are also recognized by Hong Kong health authorities:
These uses are supported by large randomized controlled trials and are incorporated into local clinical guidelines for cardiovascular disease management.
These effects are usually transient and improve as the body adapts to the medication.
If any of these occur, seek medical attention promptly.
Because interaction data for Zebeta specifically are limited, always inform your clinician of all medicines, supplements, and herbal products you are taking.
Standard dosing:
Hypertension: Start with 5 mg once daily. If blood pressure remains above target after 2-4 weeks, the dose may be increased to 10 mg once daily.
Heart failure: Begin with 5 mg once daily; titrate to 10 mg as tolerated, based on clinical response and heart rate.
Administration: Swallow the tablet whole with a glass of water. It may be taken with or without food.
Missed dose: Take the missed tablet as soon as you remember unless it is near the time of the next scheduled dose. Do not double the dose.
Overdose: Symptoms may include severe bradycardia, hypotension, and fainting. Seek emergency medical care; intravenous glucagon is an antidote in severe cases.
Discontinuation: Do not stop abruptly, especially if used for heart failure. Your doctor will advise a gradual taper to prevent rebound tachycardia or hypertension.
Regular follow-up appointments are essential to ensure optimal blood-pressure control and to watch for adverse effects.

Zebeta contains bisoprolol, which is highly selective for β1 receptors. This selectivity reduces the likelihood of bronchospasm compared with non-selective beta-blockers such as propranolol, making it a preferred option for patients with mild respiratory disease.
Yes, Zebeta is often combined with other antihypertensives (e.g., ACE inhibitors or thiazide diuretics) to achieve target blood pressure. However, dose adjustments may be required, and your clinician should monitor for excessive blood-pressure lowering.
Blood-pressure reduction can begin within a few days, but the full effect is usually observed after 2-4 weeks of consistent dosing, especially when the dose is titrated to 10 mg.
Bisoprolol does not affect blood-glucose control directly, but it can mask typical hypoglycaemia symptoms such as rapid heartbeat. Diabetic patients should monitor glucose levels closely and discuss any concerns with their doctor.
Take the missed tablet as soon as you remember unless it is close to the time of your next scheduled dose. Do not double-dose. Adjust the timing gradually to align with the new local schedule, and keep a consistent 24-hour interval thereafter.
Zebeta tablets are designed for whole-tablet intake. Crushing or splitting may affect drug absorption and should be avoided unless your prescriber explicitly advises otherwise.
Bisoprolol is a beta-blocker and is listed as a prohibited substance by many sports governing bodies (e.g., WADA). Athletes subject to testing should disclose its use and obtain a therapeutic use exemption if required.
Yes, bisoprolol tablets are marketed under various generic names. They contain the same active ingredient and are bioequivalent, though the brand name “Zebeta” may be preferred in some clinical settings.
Many over-the-counter cold remedies contain decongestants such as pseudoephedrine, which can increase heart rate and counteract beta-blockade. Use these products cautiously and discuss alternatives with a pharmacist.
The typical expiration period is 24 months from the date of manufacture when stored at room temperature. Always check the expiry date on the packaging and do not use the medication past that point.
