Nitroglycerin (GTN) is a potent vasodilator primarily used in the management of angina pectoris, heart failure, and hypertensive emergencies. As a cornerstone in cardiovascular therapy, it rapidly alleviates chest pain by dilating coronary arteries and reducing myocardial oxygen demand. Available in sublingual tablets, sprays, transdermal patches, and intravenous formulations, nitroglycerin is a must-have for emergency medical kits and clinical settings.
This expert review covers its technical specifications (pharmacokinetics, formulations), advantages over alternatives, user ratings, and pricing to help healthcare professionals make informed decisions.
