Losartan je antagonist angiotenzin II receptora koji se uglavnom koristi za tretiranje visokog krvnog pritiska (hipertenzije). Losartan je bio prvi angiotenzin II antagonist na tržištu. Merck & Co. prodaje losartan kalijum pod robnim imenom Cozaar. Losartan je dostupan u generičkoj formi.

Mada klinička evidencija pokazuje da su blokatori kalcijumskih kanala i diuretici tiazidnog tipa preferentni tretmani prvog reda za većinu pacijenata (sa gledišta efikasnosti i troška), antagonist angiotenzin II receptora poput losartan se preporučuje kao tretman prvog reda za pacijente sa manje od 55 godina koji ne mogu da tolerišu ACE inhibitore.^[6]
