werapamil

Werapamil is a calcium channel blocker used to treat high blood pressure and angina. It belongs to the class of drugs known as dihydropyridine calcium channel blockers. Werapamil works by relaxing the blood vessels, which helps to lower blood pressure and reduce the workload on the heart.

The drug is available in tablet form and is typically taken orally. It is usually prescribed as a once-daily dose. Werapamil is generally well-tolerated, but like all medications, it can cause side effects. Common side effects include headache, dizziness, and swelling of the ankles. More serious side effects are rare but can include severe allergic reactions and irregular heart rhythms.

Werapamil is not recommended for use in patients with severe liver or kidney disease, as these conditions can affect the drug's metabolism and elimination. It is also contraindicated in patients with certain heart conditions, such as severe bradycardia or heart block, as it can further slow the heart rate.

Werapamil is not a first-line treatment for high blood pressure or angina, but it can be used in patients who do not respond to other medications or who have specific medical conditions that make other drugs unsuitable. It is important to follow the advice of a healthcare professional when using werapamil, as they can provide guidance on dosage, potential interactions with other medications, and monitoring for side effects.
