Hydralazine Hydrochloride

Hydralazine Hydrochloride is a vasodilator medication used primarily for high blood pressure (hypertension) and heart failure, working by relaxing blood vessels to improve blood flow. Available as tablets or injection (brand names like Apresoline), it's given orally or intravenously, often combined with nitrates for heart failure, but can cause side effects like headaches, palpitations, or tingling (paresthesia), sometimes managed with Vitamin B6
