Losartan 12.5–100 mg Tablets
An ARB that blocks the blood-pressure-raising signal at the receptor level. A common alternative when ACE inhibitors aren't a fit. Provider-prescribed and monitored.

Supply
Losartan is an angiotensin II receptor blocker (ARB). Rather than stopping your body from making angiotensin II, it blocks the receptor that hormone binds to — so the signal to constrict blood vessels never lands. The result is more relaxed vessels and lower blood pressure.
It's typically used by adults managing hypertension, and it's a common alternative for people who develop the dry cough sometimes seen with ACE inhibitors, since ARBs work downstream of that pathway. It fits into a long-term plan built around consistent use and regular monitoring.
Losartan is a prescription medication used under medical supervision, with blood pressure checks and periodic labs guiding care. OpenDoseRx treatments are dispensed only after a licensed provider reviews your health intake and determines a prescription is appropriate for you.
