Calan – A Powerful Calcium Channel Blocker for Lowering Blood Pressure and Improving Blood Flow

Short general description of Calan

Calan is the brand name for the drug Verapamil, specifically for the sustained-release formulation known as Calan SR. Verapamil is a calcium channel blocker that helps relax and widen blood vessels in order to improve blood flow and lower blood pressure.

This medication, commonly prescribed by healthcare professionals, is highly effective in managing various conditions including:

  • Hypertension – Calan is frequently prescribed to treat high blood pressure. It works by inhibiting the entry of calcium into the muscle cells of blood vessels, causing them to relax and dilate. This process leads to a decrease in blood pressure levels.
  • Angina – Calan also plays a crucial role in managing angina, a condition characterized by chest pain or discomfort caused by reduced blood flow to the heart. By widening the blood vessels, Calan increases the blood supply to the heart muscle, relieving angina symptoms.

Calan belongs to the class of medications called calcium channel blockers, which are widely used due to their effectiveness and safety profile. Verapamil, the active ingredient in Calan, acts specifically on the calcium channels in the heart and blood vessels, providing targeted treatment for various cardiovascular conditions.
