INNOPRAN XL (propranolol hydrochloride)

Cardiovascular Approved 2003-03-12

Innopran XL is used to lower blood pressure in patients with hypertension. By controlling high blood pressure, the medication helps reduce the likelihood of fatal and nonfatal cardiovascular events, such as strokes and heart attacks. It is typically prescribed as one component of a comprehensive management plan that may include other medications and lifestyle adjustments to reach cardiovascular health goals.

How INNOPRAN XL Works

The exact mechanism of the antihypertensive effect of Innopran XL has not been fully established. Factors thought to contribute include decreased cardiac output, inhibition of renin release by the kidneys, and a reduction in tonic sympathetic nerve outflow from the brain's vasomotor centers. Although total peripheral resistance may increase initially, it typically readjusts to or below pretreatment levels with chronic use.
