hydralaziini

Hydralazine is a medication primarily used to treat high blood pressure. It belongs to a class of drugs known as vasodilators, which work by relaxing and widening blood vessels. This widening allows blood to flow more easily, thereby lowering blood pressure. Hydralazine is often prescribed for moderate to severe hypertension, and it can be used alone or in combination with other antihypertensive medications.

This drug is typically administered orally in tablet form, although an intravenous formulation is available for emergency situations where rapid blood pressure reduction is needed. The exact mechanism by which hydralazine causes vasodilation is not fully understood, but it is believed to involve interference with calcium ions within the smooth muscle cells of blood vessels.

Common side effects of hydralazine can include headache, dizziness, nausea, vomiting, and rapid heart rate (tachycardia). In some individuals, it can also cause fluid retention. A more serious, though less common, side effect is a lupus-like syndrome, which usually resolves upon discontinuation of the medication. Regular monitoring of blood counts and kidney function may be recommended for patients on long-term hydralazine therapy. It is important to take hydralazine exactly as prescribed by a healthcare professional.
