About

Losartan is a widely prescribed angiotensin II receptor blocker (ARB) primarily indicated for the effective management of essential hypertension and for reducing cardiovascular risk in specific patient populations. Its therapeutic action involves selectively blocking the binding of angiotensin II, a potent vasoconstrictor, to the AT1 receptor found in various tissues, including vascular smooth muscle and the adrenal glands. By preventing these effects, losartan induces vasodilation, lowers systemic blood pressure, and reduces aldosterone secretion, which in turn decreases sodium and water retention. A key advantage of losartan over ACE inhibitors is its mechanism of action, which does not involve the inhibition of bradykinin breakdown, thereby significantly reducing the incidence of the persistent dry cough commonly associated with ACE inhibitors. This makes it a valuable alternative for patients who cannot tolerate ACE inhibitors.

Uses

• Treatment of essential hypertension
• Reduction of stroke risk in hypertensive patients with left ventricular hypertrophy
• Management of diabetic nephropathy in type 2 diabetes
• Treatment of heart failure (off-label or specific indications)

Directions For Use

Take one tablet orally once daily, with or without food, as prescribed by your physician. Do not stop taking this medication without consulting your doctor.

Benefits

• Effective blood pressure reduction
• Lowers risk of stroke in specific populations
• Protects kidneys in diabetic patients
• Well-tolerated with low incidence of cough
• Helps manage heart failure symptoms
• Provides cardiovascular protection

Side Effects

• Dizziness
• Fatigue
• Hypotension (low blood pressure)
• Hyperkalemia (high potassium levels)
• Renal dysfunction
• Back pain
• Upper respiratory infection
• Cough (less common than ACE inhibitors)
• Diarrhea
• Nausea

• Muscle cramps

Safety Measures

• Alcohol - Avoid or limit alcohol consumption as it can further lower blood pressure and increase dizziness.
• Pregnancy - Contraindicated in the second and third trimesters due to risk of fetal injury or death. Avoid in first trimester.
• Breastfeeding - Not recommended. Losartan may pass into breast milk and could harm a nursing infant.
• Liver - Use with caution in patients with hepatic impairment; a lower starting dose may be considered.
• Kidney - Use with caution in patients with renal artery stenosis or severe renal impairment; monitor kidney function closely.
• Lung - Generally safe for patients with lung conditions; less likely to cause cough compared to ACE inhibitors.
