What is Losartan

Losartan is classified as an angiotensin II receptor blocker (ARB), which functions by inhibiting the action of a substance in the body that induces constriction of blood vessels. Candesartan, Irbesartan, Olmesartan, Telmisartan, and Valsartan are additional pharmaceutical agents in the same therapeutic class.

Uses of Losartan?

Losartan is administered orally as a tablet and is predominantly marketed under the trade name Cozaar. Cozaar, a widely recognized brand name for the medication losartan, is frequently employed in the management of hypertension, a prevalent condition characterized by elevated blood pressure levels.

How does it work?

Losartan functions by inhibiting the activity of angiotensin II, thereby inducing vasodilation and promoting enhanced hemodynamic circulation, ultimately reducing arterial pressure. The vasodilation induced by this process also alleviates cardiac workload and prevents vascular damage in the brain, heart, and kidneys.

How to take Losartan?

Adherence to the dosage of Losartan and diligent blood pressure monitoring are crucial aspects of administering this medication. You can take Losartan orally, either with or without food consumption. The administration of Losartan to pregnant women during the final six months of gestation is contraindicated due to the potential risks of fetal mortality or severe harm.
