1.    What Istin 5mg Tablets are and what they are used for

Istin 5mg Tablets contain the active substance amlodipine which belongs to a group of medicines called calcium antagonists.

Istin 5mg Tablets are used to treat high blood pressure (hypertension) or a certain type of chest pain called angina, a rare form of which is Prinzmetal’s or variant angina.

In patients with high blood pressure this medicine works by relaxing blood vessels, so that blood passes through them more easily. In patients with angina Istin 5mg Tablets work by improving blood supply to the heart muscle which then receives more oxygen and as a result chest pain is prevented. This medicine does not provide immediate relief of chest pain from angina.
