Hydralazine HydrochlorideThird Party Manufacturing in India

Hydralazine Hydrochloride works by directly relaxing arteriolar smooth muscle, causing vasodilation of peripheral blood vessels. This reduces peripheral vascular resistance, leading to a decrease in blood pressure. The exact mechanism involves interference with calcium ion transport within the vascular smooth muscle cells, preventing the contraction required for vessel constriction. Unlike other antihypertensives that primarily affect cardiac output or sympathetic nervous system activity, hydralazine acts predominantly on the arterioles with minimal effect on venous capacitance vessels. This selective arteriolar dilation triggers a reflex sympathetic response that can increase heart rate, cardiac output, and renin release, which is why it is often prescribed alongside a beta-blocker and a diuretic. It is particularly effective for managing moderate to severe hypertension and is included in the WHO Essential Medicines List.

Therapeutic Uses

Hydralazine Hydrochloride is prescribed for the treatment of:

• Hypertension: Used for moderate to severe hypertension, often as part of combination therapy with a diuretic and a beta-blocker to counteract reflex tachycardia and fluid retention.
• Hypertensive Crisis: Administered intravenously or intramuscularly in hospital settings for acute blood pressure management.
• Heart Failure: Used as an adjunct in the treatment of chronic heart failure, particularly in patients who cannot tolerate ACE inhibitors or angiotensin receptor blockers.

Why Manufacturers Choose Hydralazine Hydrochloride

Hydralazine Hydrochloride remains a cornerstone antihypertensive with consistent demand across Indian pharmaceutical markets. Its inclusion in the WHO Essential Medicines List and its proven efficacy-to-safety ratio make it a reliable molecule for PCD franchise operations and institutional supply chains. The availability of multiple tablet strengths from 10mg to 100mg provides formulation flexibility for combination products targeting different patient populations.
