Pactorin Retard 2.6 mg is a sustained-release tablet used primarily for the prevention of angina pectoris (chest pain) in individuals with coronary artery disease. This formulation ensures a prolonged action, preventing angina episodes throughout the day. Nitroglycerin, the active ingredient in Pactorin, works by relaxing the blood vessels, allowing blood to flow more easily, and reducing the workload on the heart.
Nitroglycerin (Glyceryl Trinitrate) helps in the relaxation of smooth muscles in the blood vessels, leading to vasodilation (widening of blood vessels). This action helps to alleviate chest pain and improves oxygen delivery to the heart.
