What is Ramipril for?

Ramipril belongs to a class of medications called angiotensin-converting enzyme inhibitors (ACEIs). ACEIs block the substances that constrict the blood vessels and hence more blood and oxygen can reach the heart. Ramipril is therefore used in treating and preventing heart conditions, such as heart failure and myocardial infarction.

Ramipril is taken by mouth as tablets or capsules. It may be taken with or without food. The dosage may be adjusted by your doctor depending on your medical condition and response to medication.

Initially 2.5 mg once daily, with the first dose preferably given at bedtime. Maintenance dose is 2.5-5 mg daily as a single dose, up to 10 mg daily as needed.


Heart failure
Initially 1.25 mg once daily. Maximum dose is 10 mg daily. Doses over 2.5 mg may be given in single or 2 divided doses.
