- Therapeutic Use: Primary treatment for hypertension, adjunct therapy for edema and congestive heart failure
- Delivery Forms: Oral tablets, various dosage strengths (e.g., 25 mg/25 mg, 25 mg/50 mg)
- Generic Availability: Widely available, patent expirations largely occurred in the late 2000s
Mechanism of Action:
- Hydralazine lowers blood pressure via direct arteriolar vasodilation.
- Hydrochlorothiazide enhances sodium excretion, reducing blood volume and pressure.
- Synergistically, it provides a comprehensive approach to blood pressure control.
