Tonorma [atenolol, chlorthalidone, nifedipine] (30 tablets)

Description

Tonorma (Atenolol, Chlorthalidone, Nifedipine) – 30 Coated Tablets

Tonorma is a combination antihypertensive medication formulated to provide comprehensive blood pressure control through multiple pharmacological mechanisms. It contains atenolol, chlorthalidone, and nifedipine — three well-established agents that act synergistically to reduce blood pressure and improve cardiovascular outcomes.

This multi-component formulation is commonly used in the management of moderate to severe hypertension, especially in patients requiring combination therapy. The presence of different active ingredients allows for improved efficacy compared to monotherapy.

Mechanism of Action

This medication combines three complementary mechanisms:

• Atenolol reduces heart rate and cardiac output by blocking β1-adrenergic receptors
• Chlorthalidone promotes diuresis and reduces plasma volume
• Nifedipine relaxes vascular smooth muscle and dilates blood vessels

The combined effect results in sustained blood pressure reduction and improved cardiovascular function.
