Propranolol SR 40 mg (Sustained-Release) tablets are beta-blockers used to manage hypertension, angina, arrhythmias, and prevent migraines and tremors.

It slows the heart rate and relaxes blood vessels, allowing better blood flow and reducing heart strain.

It must be taken whole, usually on an empty stomach, to manage conditions like tremor and anxiety.

Hypertension Management: It lowers high blood pressure by reducing the heart rate and force of contraction, which helps prevent strokes, heart attacks, and kidney damage.

Migraine Prevention: It is effective in preventing migraine headaches, reducing their frequency and severity by improving blood flow to the brain.

Anxiety and Physical Symptoms: Propranolol is often used off-label to manage physical symptoms of anxiety (performance anxiety, social anxiety) such as a rapid heart rate (palpitations), shaking, sweating, and trembling.
