Full Form of GTN
What is GTN?
Glyceryl Trinitrate (GTN) is a potent nitrate vasodilator widely used to treat and prevent angina pectoris. In India, it is available as sublingual tablets, sprays, and transdermal patches, and is a cornerstone of emergency cardiac care. GTN works by relaxing vascular smooth muscle, reducing preload and afterload, thereby decreasing myocardial oxygen demand and increasing coronary blood flow. It is commonly prescribed in hospitals and clinics by cardiologists and general physicians for patients experiencing chest pain, often during acute coronary syndrome or stable angina episodes. GTN is also used prophylactically before activities that may trigger angina. In Indian medical education, GTN is a frequently tested topic in pharmacology for MBBS, nursing, and pharmacy exams, especially in NEET PG and state-level entrance tests. Patients are educated on proper sublingual administration and storage to maintain efficacy. The drug is also known as nitroglycerin and shares similarities with other nitrates like isosorbide dinitrate. Understanding GTN's mechanism, side effects (headache, hypotension), and contraindications is essential for healthcare professionals in India.
