These tablets are available in two different strengths and your doctor will have decided which is the most suitable for you.

Co-tenidone 100/25 mg Tablets contain 100 mg of atenolol and 25 mg of chlortalidone as the active ingredients.
Atenolol belongs to a group of medicines known as beta blockers which work on receptors in the heart to lower blood pressure, and chlortalidone belongs to a group of medicines known as diuretics which work by increasing the amount of urine passed (a diuretic action), also helping to lower blood pressure.
Co-tenidone Tablets are used to treat hypertension (high blood pressure).
