Zanidip is a prescription medication primarily used to treat high blood pressure (hypertension) in adults. It contains the active ingredient lercanidipine, which belongs to a class of medicines called dihydropyridine calcium channel blockers.
Zanidip works by blocking the entry of calcium ions into the muscle cells that make up the walls of blood vessels. This results in the relaxation and widening of the blood vessels, which then allows blood to flow more easily and effectively through them. This in turn lowers blood pressure, which can help to reduce the strain on the heart and lower the risk of associated complications.
Use and Dosage
Lercanidipine tablets are available in two strengths, 10 mg, and 20 mg. The tablets should be swallowed whole with water, if possible. You should take the tablets as directed by your doctor, with a drink of water and approximately 30 minutes before a meal, on an empty stomach. This is because fatty foods can increase the amount of lercanidipine that your body absorbs, which may lead to side effects.
- For adults, the usual dose is one 10 mg film-coated tablet taken daily at the same time each day. Take it in the morning, at least 15 minutes before breakfast, as a high-fat meal may increase blood levels of the drug. Your doctor may increase your dose to one Zanidip 20 mg film-coated tablet daily, if necessary but follow their advice carefully.
- Elderly patients do not require a daily dose adjustment but should be monitored carefully. Patients with liver or kidney problems need care when starting treatment, and a daily dose increase to 20 mg should be approached with caution.
- Zanidip should not be used in children under 18 years of age. If you have any further questions about the use of Zanidip, consult your doctor.
If you miss to take your lercanidipine tablet at the usual time, take it 30 minutes before your next meal. If you do not remember until the following day, skip the missed dose and do not take two doses together to make up for it.
