Coras is used to prevent angina.
Angina is a pain or uncomfortable feeling in the chest, often spreading to the arms or neck and sometimes to the shoulders and back. This may be caused by too little blood and oxygen getting to the heart. The pain of angina is usually brought on by exercise or stress.
Ask your doctor if you have any questions about why Coras has been prescribed for you.
Your doctor may have prescribed Coras for another reason.
Coras contains the active ingredient diltiazem hydrochloride. It belongs to a group of medicines called calcium channel blockers.
These medicines work by widening blood vessels, letting more blood and oxygen reach the heart. They do not change the amount of calcium in your blood or bones.
Coras is not recommended for use in children, as its safety and effectiveness have not been established in children.
Coras is available only with a doctor's prescription.

Your doctor may advise you to keep a supply of angina tablets or spray for use under the tongue.
