Propranolol HydrochlorideThird Party Manufacturing in India

Propranolol Hydrochloride works by competitively blocking beta-adrenergic receptors throughout the body. As a non-selective beta blocker, it antagonizes both beta-1 receptors located primarily in the heart and beta-2 receptors found in bronchial smooth muscle, vascular smooth muscle, and other peripheral tissues.

By blocking beta-1 receptors in the myocardium, propranolol reduces heart rate, myocardial contractility, and cardiac output, thereby decreasing myocardial oxygen demand. This mechanism underlies its efficacy in hypertension, angina pectoris, and post-myocardial infarction prophylaxis. The drug also suppresses renin release from the juxtaglomerular apparatus in the kidneys, reducing angiotensin II production and further contributing to blood pressure lowering.

Propranolol is unique among beta blockers because it is highly lipophilic and penetrates the central nervous system readily. This CNS penetration accounts for its efficacy in migraine prophylaxis, essential tremor, and performance anxiety, where central beta receptor blockade modulates sympathetic outflow. At higher doses, propranolol exhibits membrane-stabilizing activity and blocks sodium channels, though this quinidine-like effect is not clinically significant at therapeutic doses. The drug undergoes extensive first-pass hepatic metabolism, resulting in variable oral bioavailability between individuals, which necessitates careful dose individualization.

Propranolol Hydrochloride is a versatile non-selective beta blocker with applications spanning cardiology, neurology, and psychiatry due to its unique central nervous system penetration.

Therapeutic Uses

• Hypertension: Reduces blood pressure by decreasing cardiac output and suppressing renin release, effective as monotherapy or in combination with diuretics and vasodilators.
• Angina Pectoris: Improves exercise tolerance and reduces anginal episodes by decreasing myocardial oxygen demand through negative chronotropic and inotropic effects.
• Post-Myocardial Infarction: Reduces the risk of cardiovascular mortality and recurrent infarction when initiated early after MI.
• Migraine Prophylaxis: First-line preventive therapy for episodic migraine, reducing attack frequency and severity through central beta receptor blockade.
• Essential Tremor: The treatment of choice for essential tremor, particularly of the hands, through peripheral beta-2 receptor blockade in skeletal muscle.
• Performance Anxiety: Reduces somatic symptoms of anxiety such as palpitations, tremor, and sweating via peripheral beta blockade.
• Thyrotoxicosis: Used adjunctively to control tachycardia, tremor, and anxiety in hyperthyroid states.
• Infantile Haemangioma: Licensed for proliferating haemangiomas requiring systemic therapy.
