1. What Securon SR / Half Securon SR is and what is it used for

Securon SR and Half Securon SR tablets belong to a group of medicines called calcium channel blockers. Calcium channel blockers change the amount of calcium getting into the muscle cells in your heart and blood vessels. This can change the strength and speed with which your heart beats. It also opens up the blood vessels so blood can be pumped around the body more easily. This helps more oxygen to get to your heart muscle and can lower your blood pressure.

Securon SR and Half Securon SR tablets are used to treat hypertension (high blood pressure) and to prevent angina (chest pain) attacks. The tablets may also be prescribed following a heart attack, to prevent another attack occuring.

The active ingredient in Securon SR and Half Securon SR tablets is verapamil hydrochloride.
