Fimasartan is used to manage high blood pressure (hypertension). It belongs to a class of medicines called angiotensin II receptor blockers (ARBs), which help relax and widen blood vessels.
Fimasartan is commonly used for:
• Hypertension: Lowers high blood pressure, reducing strain on the heart and blood vessels.
• Long-term blood pressure control: Used as an ongoing treatment to help keep blood pressure within a healthy range.
• Reducing cardiovascular risk: Helps lower the risk of complications linked to persistently high blood pressure, such as heart attack, stroke, and kidney damage, as part of overall treatment.

Fimasartan works by blocking the action of a hormone that narrows blood vessels.
The body naturally produces a hormone called angiotensin II, which causes blood vessels to constrict and raises blood pressure. Fimasartan blocks the receptors that angiotensin II acts on, preventing this narrowing effect.
By stopping angiotensin II from acting on blood vessels, Fimasartan allows the vessels to relax and widen, which reduces the resistance to blood flow and lowers blood pressure.
Fimasartan is a long-acting ARB, meaning its blood-pressure-lowering effect lasts over an extended period, allowing for once-daily dosing.
