Sanlol Sr 40mg Tab (Propranolol) is a beta-blocker. It works by blocking the effects of adrenaline (epinephrine) and noradrenaline (norepinephrine) on the heart and blood vessels. This reduces heart rate, blood pressure, and the force of heart contractions. In migraine prevention, it's thought to affect blood vessel constriction.
