Drug Uses

This medication is a beta-blocker, used to treat high blood pressure. Lowering high blood pressure helps prevent strokes, heart attacks and kidney problems. This drug works by blocking the action of certain natural chemicals in your body (such as epinephrine) that affect the heart and blood vessels. This results in a lowering of heart rate, blood pressure, and strain on the heart.

How to use

Take this medication by mouth usually once daily at bedtime; or as directed by your doctor. Swallow the capsules whole; do not crush or chew the capsules. Use this medication regularly in order to get the most benefit from it. Remember to use it at the same time each day. This drug is not effective if you use it only when a chest pain or a migraine headache occurs. It is very important to take this medication regularly as prescribed to help prevent these conditions. The dosage is based on your medical condition and response to therapy. It may take 1 or 2 weeks before the full benefit of this drug takes effect. It is important to continue taking this medication even if you feel well. Most people with high blood pressure do not feel sick. Do not suddenly stop taking this medication without consulting your doctor. Your condition may become worse when the drug is suddenly stopped.

Drug Class and Mechanism

The mechanism of the antihypertensive effects of innopran XL has not been established. Among the factors that may be involved are decreased cardiac output, inhibition of renin release by the kidneys, and diminution of tonic sympathetic nerve outflow from vasomotor centers in the brain. It has been suggested, but not established, that propranolol may achieve a better antihypertensive effect in patients with normal or elevated plasma renin activity (PRA) than those with low PRA.

Missed Dose

If you miss a dose, take it as soon as you remember, but not if it is within 8 hours of the next dose. If it is within 8 hours of the next dose, skip the missed dose and resume your usual dosing schedule. Do not double the dose to catch up.

Storage

Store at room temperature (77 degrees F or 25 degrees C) away from light and moisture. Brief storage between 59-86 degrees F (15-30 degrees C) is permitted. Do not store in the bathroom. Keep all medicines away from children and pets.
