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