What condition is hydralazine hydrochloride primarily indicated for?

Hydralazine hydrochloride is primarily indicated for the treatment of hypertension. This medication acts as a direct vasodilator, which means it works by relaxing the muscles in the blood vessels, leading to their dilation. As a result, blood can flow more easily, which helps to lower blood pressure.

While hydralazine can be used in specific cases of heart failure as an adjunct therapy, its primary role is in managing high blood pressure. It is not typically indicated for arrhythmia or angina, which have different therapeutic approaches and medications associated with their management. Understanding the primary use of hydralazine emphasizes its effectiveness in treating hypertension while clarifying its role in the broader spectrum of cardiovascular conditions.
