About Cozaar Tablet 50mg

Cozaar Tablet 50mg Uses

• High blood pressure (hypertension) management
• Reducing the risk of stroke in patients with high blood pressure and thickened heart muscle
• Slowing kidney damage progression in people with type 2 diabetes and kidney disease
• Long term heart protection when other blood pressure medicines are not tolerated

Drug Class

• Angiotensin II receptor blocker (ARB)

What Experts Say

Losartan works by blocking angiotensin II, a hormone that narrows blood vessels and raises blood pressure. By stopping this hormone from binding to its receptor, blood vessels relax and blood flows more easily, which lowers overall pressure on the heart and reduces the workload placed on it over time.

The 50mg strength is a common starting dose for adults with hypertension, and doctors may adjust it upward based on response after a few weeks of consistent use. Losartan is often chosen over ACE inhibitors for people who develop a persistent dry cough on that other drug class, since ARBs rarely cause this side effect while offering a similar level of blood pressure control.

Regular blood pressure checks and periodic kidney function or potassium level tests are recommended during treatment, especially in the first few months or after any dose change. Staying well hydrated and avoiding sudden dose changes helps prevent drops in blood pressure that can cause dizziness or fainting, particularly in warmer weather or during illness with fluid loss.

Drug Interactions

• NSAIDs such as ibuprofen: May reduce the blood pressure lowering effect and raise kidney risk.
• Potassium sparing diuretics and potassium supplements: Combined use can push potassium levels too high.
• Lithium: Blood lithium levels may rise, increasing toxicity risk.
• Other blood pressure medicines: Additive effect can cause excessive blood pressure drops.
• Rifampicin: May reduce losartan's effectiveness by speeding up its breakdown.
• Fluconazole: Can reduce conversion of losartan to its active form.

Risks and warnings

• Pregnancy: Contraindicated, as ARBs can cause fetal injury and death when used during the second and third trimesters.
• Kidney artery narrowing: Use with caution in patients with renal artery stenosis.
• High potassium: May raise blood potassium levels, especially with kidney impairment.
• Dehydration: Low fluid or salt levels before starting treatment can cause a sharp blood pressure drop.
• Liver disease: Lower doses are usually needed in significant hepatic impairment.
• Allergic reaction: Rare cases of facial or throat swelling have been reported.
