Isoptin SR (active ingredient: verapamil) is a prescription medication indicated for the following:

  1. Hypertension: Isoptin SR is used to treat high blood pressure (hypertension) to help lower and manage blood pressure levels.
  2. Angina Pectoris: It is indicated for the treatment of angina pectoris (chest pain) due to coronary artery disease, helping to prevent angina attacks.
  3. Supraventricular Tachycardia: Isoptin SR is used for the management of certain types of supraventricular tachycardia (SVT), including atrial fibrillation and atrial flutter, to help control the heart rate.

Isoptin SR belongs to a class of drugs known as calcium channel blockers, which work by inhibiting calcium influx into cardiac and smooth muscle cells, leading to relaxation of the blood vessels, reduced heart rate, and decreased myocardial oxygen demand.

Isoptin SR (Verapamil) is a medication that can be taken orally as film-coated tablets. It is usually prescribed to be taken once daily in the morning, or every 12 hours as directed by a doctor. Take the tablet with a meal and swallow it whole with a glass of water. Chewing, crushing, or cutting the medication is not recommended as it may cause the active ingredients to be released at once, which can increase the risk of side effects.

The recommended dosages of Verapamil vary depending on the condition being treated and the form of the medication being used. For example, the typical dose for hypertension in adults ranges from 80-120mg orally every 8 hours, while the usual dose for angina after a heart attack using slow-release tablets is 360mg split into 2-3 doses per day. Follow the specific dosing instructions provided by your doctor or pharmacist.

Take Verapamil tablet exactly as prescribed by the doctor. If you miss a dose, take it as soon as possible and continue with your regular schedule. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.
