Description of PROPENOL SR 40 (Propranolol SR 40mg)

PROPENOL SR 40 contains Propranolol Hydrochloride 40 mg in a sustained-release formulation. It works by blocking the action of stress hormones (adrenaline and noradrenaline) on the heart and blood vessels. This leads to a reduction in heart rate, decreased strain on the heart, controlled blood pressure, and overall cardiovascular stability.
