Calan Sr, also known by its generic name verapamil hydrochloride, is a medication commonly prescribed to treat high blood pressure, angina (chest pain), and certain heart rhythm disorders.

Verapamil hydrochloride is available in extended-release form under the brand name Calan Sr. The extended-release formulation of the medication allows for once-daily dosing, providing continuous delivery of the drug over a 24-hour period.

When taking Calan Sr, it is important to follow your healthcare provider’s instructions carefully and not to exceed the prescribed dosage. This medication may interact with other drugs or medical conditions, so it is essential to inform your healthcare provider about any other medications you are taking.

In clinical studies evaluating the efficacy of Calan Sr, researchers have found that the medication effectively lowers blood pressure and reduces the frequency and severity of angina episodes in patients with coronary artery disease.

How Calan Sr (Verapamil Hydrochloride) Works

Calan Sr, also known as verapamil hydrochloride, is a calcium channel blocker that works by relaxing the muscles of your heart and blood vessels. This leads to improved blood flow and helps lower blood pressure.

Verapamil hydrochloride specifically targets calcium channels in the heart and blood vessels. By blocking these calcium channels, Calan Sr reduces the amount of calcium that enters the muscle cells of the heart and blood vessels. This action helps to slow down the heart rate, decrease the force of heart contractions, and dilate (widen) blood vessels, leading to decreased blood pressure.

Benefits of Calan Sr:

  • Improves blood flow
  • Lowers blood pressure
  • Reduces heart rate

Studies and results:
