Table of contents:

Ranexa, also known as ranolazine, is a prescription medication used to treat chronic angina, a type of chest pain that occurs when the heart muscle does not receive enough oxygen. This type of angina is caused by reduced blood flow to the heart and can lead to chest pain or discomfort. Ranexa works by improving oxygen delivery to the heart, which helps reduce the severity and frequency of angina episodes.

Ranexa is intended to be used in combination with other angina medications, such as beta-blockers or calcium channel blockers. It helps improve blood flow by helping the heart relax and expand during activity. For some individuals, Ranexa can provide long-term relief from angina symptoms when used as part of a comprehensive treatment plan. It is supplied in Prolonged Release, extended-release tablets in 500 mg and 1000 mg strengths.

Uses and Dosage

Ranolazine is available in tablet form to be taken orally with or without food, as directed by a healthcare provider, usually twice daily. To reduce the risk of side effects, swallow the tablet whole and do not crush, split, or chew it.

Inform your doctor and pharmacist of all products you use, including prescription drugs, non-prescription drugs, and herbal products. Do not take more than the prescribed amount. Speak with your doctor or pharmacist for further information. If a dose of RANEXA tablet is missed, take the prescribed dose at the next scheduled time; do not double the next dose.
