1. What Coracten XL is and what it is used for
Coracten XL contains nifedipine, which belongs to a group of medicines called calcium-channel blockers.
Used to treat:
• high blood pressure in adults To prevent:
• chronic stable angina pectoris (heart/chest pain) in adults.
For high blood pressure: Coracten XL works by relaxing and expanding the blood vessels. This makes the blood flow more easily and lowers blood pressure. Lower blood pressure reduces the strain on your heart.
For angina: Coracten XL works by relaxing and expanding the arteries supplying the heart. This allows more blood and oxygen to reach the heart and decreases the strain on it. Your angina attacks will be less severe and less frequent if there is less strain on the heart.
PLEASE NOTE: These capsules are sustained-release capsules which release the active ingredient slowly over 12 hours. Do not use to treat attacks of angina or heart attacks when they happen. See your doctor if you are unsure why you have been prescribed these capsules.
