INTRODUCTION
INDERAL 20MG contains Propranolol which belongs to a group of medicines called beta-blockers, which have effects on the heart and circulation of the body. It is used to treat hypertension, angina, arrythmias (disorders of heart rhythm), migraine and proliferating infantile hemangioma.
Propranolol is a nonselective beta-adrenergic receptor blocking agent which specifically competes with beta-adrenergic receptor agonist agents for available receptor sites. By blocking the response to beta 1 and beta 2 adrenergic stimulation, it helps in decreasing the heart rate, myocardial contractility, blood pressure, and myocardial oxygen demand. It reduces portal pressure by producing splanchnic vasoconstriction thereby reducing portal blood flow.
Before taking INDERAL 20MG, tell your doctor if you have asthma, heart, kidney or liver problems. It is not recommended for use during pregnant and breastfeeding. The common side effects are tiredness, weakness cold fingers and toes, irregular or slow heartbeat, numbness in your fingers and breathlessness.
