5 Conservation of Losartan Viatris
Losartan belongs to a group of medicines called angiotensin II receptor antagonists.
Angiotensin II is a substance produced in the body that binds to receptors present in blood vessels, causing them to narrow. This leads to an increase in blood pressure.
Losartan prevents angiotensin II from binding to these receptors, resulting in the relaxation of blood vessels, which in turn lowers blood pressure. Losartan reduces the worsening of kidney function in patients with high blood pressure and type 2 diabetes.
Losartan is used:
Do not take Losartan Viatris

It is not recommended to use losartan at the start of pregnancy, and in no case should it be administered after the third month of pregnancy, as it may cause serious harm to your baby when administered from that time on (see section pregnancy).
