Provanol SR 80 Tablet

Provanol SR 80 Tablet contains propranolol hydrochloride 80 mg in each sustained-release tablet. It belongs to the beta-blocker class and is used to help manage conditions such as high blood pressure, chest pain (angina), certain fast or irregular heart rhythms, and tremor. Because it is an extended-release tablet, Provanol SR 80 Tablet is designed to release medicine gradually over time rather than all at once.

How it works: Propranolol works by blocking beta receptors, which slows the heart rate and reduces the force with which the heart pumps. In the sustained-release Provanol SR 80 Tablet, this effect is delivered gradually, helping provide longer-lasting control from a single tablet.

Provanol SR 80 Tablet is a higher-strength, sustained-release option compared with Provanol 10 Tablet, Provanol 20 Tablet, and Provanol SR 40 Tablet. A doctor may choose this strength for people who need steadier all-day control and are already assessed to tolerate propranolol; it is not the usual starting strength for everyone.

• High blood pressure
• Angina (chest pain)
• Certain irregular heart rhythms
• Tremor
• Migraine prevention
• Anxiety-related physical symptoms in selected patients

• Swallow Provanol SR 80 Tablet whole with water; do not crush, chew, or split it because it is a sustained-release tablet.
• Take it at the same time each day to keep a steady level of medicine in your body.
• It can be taken with or without food, but taking it the same way each day is best.
• If it upsets your stomach, taking it with food may help.
• Do not stop taking it suddenly unless your doctor tells you to, because that can worsen heart symptoms.
• If you miss a dose, take it when you remember unless it is close to the next dose; do not double up.

Each Provanol SR 80 Tablet provides propranolol 80 mg in a sustained-release form. The exact dose and how often it is taken vary by condition and response, but this strength is often used once daily or as directed by the prescriber. Your doctor decides the maximum daily amount for you based on your heart rate, blood pressure, and other medicines.

Do not change your dose or stop the medicine without speaking to your doctor.
