Amlodipine is used to treat high blood pressure (hypertension), some types of angina and other conditions caused by coronary artery disease. Amlodipine is a calcium channel blocker that works by changing the movement of calcium in the heart and blood vessel cells. This widens the blood vessels which increases the blood and oxygen supply to the heart and also lowers blood pressure.

You should take it regularly as prescribed for this medicine to be most effective, even if you feel better.

In Prevention of Angina (heart-related chest pain)

Stamlo 5 Tablet relaxes the blood vessels and improves blood flow around your body. This means that more oxygen gets to your heart and reduces the risk of getting chest pain (angina). This medicine should not be used to treat chest pain which is already happening. It is used to prevent or reduce the frequency of angina attacks. This medicine needs to be taken regularly as prescribed for it to work effectively. So, it is important to keep taking it even if you feel well and have no symptoms.

Directions for use

Take this medicine in the dose and duration as advised by your doctor. Swallow it as a whole. Do not chew, crush or break it. Stamlo 5 Tablet may be taken with or without food, but it is better to take it at a fixed time.

How it works?

Stamlo 5 Tablet is a calcium channel blocker. In high blood pressure, it normalizes the blood pressure by relaxing the blood vessels to reduce the pressure on them, thereby improving the blood flow in the body. In heart-related chest pain (angina), the enhanced blood flow in the body relaxes the heart muscles by reducing the workload on the heart. It also improves the oxygen flow in the body, thereby, preventing any heart-related chest pain.
