How CARVISTAR 12.5MG TABLET Works
CARVISTAR 12.5MG TABLET contains a medicine called Carvedilol which is a beta-blocker that works by blocking both beta and alpha receptors on blood vessels and the heart.
For hypertension, carvedilol blocks beta-1 receptors in the heart, which slows the heart rate and reduces the force of heart contractions, lowering blood pressure. It also blocks alpha-1 receptors on blood vessels, causing them to relax and widen, which further reduces blood pressure.
For angina (chest pain), carvedilol decreases the workload on the heart by reducing the heart rate and lowering blood pressure, which helps improve oxygen supply to the heart muscle and relieves chest pain.
In heart failure, carvedilol’s effects on both beta and alpha receptors reduce strain on the heart, improve heart function over time, and help prevent worsening of symptoms by protecting the heart muscle from stress and damage.
