Used primarily in the treatment of hypertension (high blood pressure), fosinopril sodium helps lower blood pressure by inhibiting the angiotensin-converting enzyme (ACE), which reduces the production of angiotensin II—a substance that narrows blood vessels. This action promotes vasodilation, easing the workload on the heart and improving blood flow. It is also prescribed for heart failure management, often in combination with diuretics or other antihypertensives. Due to its dual excretion pathway (hepatic and renal), it is considered a suitable option for patients with impaired kidney function. Fosinopril sodium is taken orally, typically once daily, and offers sustained blood pressure control with consistent use.
