Introduction to Cozaar (Losartan) 20mg
Cozaar (Losartan) 20mg is a powerful prescription medicine used to manage high blood pressure (hypertension) and protect the kidneys in patients with type 2 diabetes or cardiovascular risk. Presulock 20mg, a generic version, contains the same active ingredient, offering similar therapeutic effects under medical supervision.
Cozaar (Losartan) 20mg is classified under Prescription Medicines, Antihypertensive Drugs, Angiotensin II Receptor Blockers (ARBs), and Oral Cardiovascular Therapy. It works by relaxing blood vessels, reducing blood pressure, and improving blood flow to the heart and kidneys.
What Is Cozaar (Losartan)?
Cozaar is the brand name for Losartan, an oral medication widely used for managing hypertension and related heart or kidney conditions.
Losartan belongs to a class of medicines known as Angiotensin II Receptor Blockers (ARBs). These medicines prevent blood vessels from narrowing, thereby lowering blood pressure and reducing the risk of heart attack, stroke, and kidney damage.
Generic versions such as Presulock 20mg may be used depending on physician recommendation and regional availability.
Drug Class and Mechanism of Action
Losartan is classified as an ARB with strong antihypertensive and organ-protective properties.
How Losartan Works
- Blocks the action of angiotensin II, a hormone that narrows blood vessels
- Relaxes blood vessels to reduce blood pressure
- Protects the kidneys from damage in diabetic patients
- Helps prevent stroke, heart attack, and other cardiovascular complications
How Cozaar Works in the Body
After oral administration, Losartan blocks angiotensin II receptors in blood vessels, causing them to relax and improving blood flow. This lowers blood pressure and reduces stress on the heart and kidneys.
Key Actions of Losartan
- Reduces high blood pressure
- Protects kidneys in diabetic patients
- Improves blood flow to the heart

Generic versions such as Presulock deliver the same active compound, providing similar antihypertensive therapy under professional supervision.
