BETACAP 20 TABLET

💓🧠 Propranolol 20mg Tablet: A Complete Medical Overview

Propranolol 20mg is a non-selective beta-blocker medication commonly used to treat heart conditions, anxiety, and neurological disorders. By blocking the action of stress hormones like adrenaline (epinephrine) on beta-adrenergic receptors, Propranolol helps reduce heart rate, blood pressure, and symptoms associated with overactive sympathetic nervous system activity.

🔬 Mechanism of Action

Propranolol acts by blocking β1 and β2 receptors:

• β1 receptors (in the heart): Blocking them slows the heart rate and reduces cardiac output, which lowers blood pressure and oxygen demand.

• β2 receptors (in lungs and blood vessels): Blocking these can constrict airways and reduce tremors.

This dual action makes it effective for cardiovascular and neurological indications but requires caution in respiratory conditions like asthma.

📌 Clinical Indications

Propranolol 20mg is prescribed for several medical conditions, including:

🫀 Cardiovascular Uses:

• Hypertension (high blood pressure)

• Cardiac arrhythmias (irregular heartbeat)

• Myocardial infarction (to prevent future heart attacks)

• Hypertrophic subaortic stenosis

🧠 Neurological and Other Uses:

• Migraine prevention

• Essential tremors

• Performance anxiety / situational anxiety

• Thyrotoxicosis (managing symptoms like palpitations)

💊 Dosage and Administration

• Usual adult dose: 20mg taken 2 to 4 times a day, depending on the condition.

• For anxiety, a single 20–40mg dose may be taken 1 hour before a stressful event.

• The dosage may be increased or adjusted based on therapeutic response and patient tolerance.

⚠️ Never stop Propranolol abruptly, especially in heart patients, as it can lead to rebound hypertension, angina, or even heart attack.

⚠️ Precautions and Warnings

• Asthma/COPD: Avoid, as β2 blockade may cause bronchospasm.

• Diabetes: Can mask hypoglycemia symptoms such as fast heartbeat.

• Bradycardia or heart block: Use with caution in patients with slow or irregular heartbeats.

• Pregnancy and breastfeeding: Use only under medical supervision.

• Peripheral artery disease: May worsen symptoms like cold extremities.

🔄 Drug Interactions

Propranolol can interact with:

• Calcium channel blockers (e.g., verapamil, diltiazem): Increased risk of heart block or low heart rate

• Antidiabetic medications: May mask symptoms of low blood sugar

• Clonidine: Risk of rebound hypertension if stopped abruptly

• NSAIDs: May reduce blood pressure-lowering effects
