Nitroglycerin
Pharmacology
Nitroglycerin causes relaxation of vascular smooth muscle, producing a vasodilator effect on both peripheral arteries and veins. Dilation of veins promote peripheral pooling of blood and decreases venous return to the heart, thereby reducing left ventricular end-diastolic pressure (preload) and relaxation of arteries reduce systemic vascular resistance and arterial pressure (afterload).
Contraindications
Nitroglycerin dilates peripheral blood vessels and may increase the antihypertensive properties of vasodilators, calcium antagonists, beta-adrenergic blockers. Concomitant use of nitrates with tricyclic antidepressants and alcohol may cause high blood pressure. Concomitant use of nitrates with phosphodiesterase type 5 (PDE5) inhibitors, such as sildenafil, vardenafil and tadalafil cause fall in blood pressure. Aspirin decreases the clearance and enhances the hemodynamic effects of nitroglycerin. Nitroglycerin may reduce the pharmacologic effects of heparin when used concomitantly. Nitrates increase the bioavailability of dihydroergotamine.
Side Effects
Nitroglycerin is contraindicated in patients with a known hypersensitivity to nitroglycerin, other organic nitrates, or nitrites or to the excipients of the medicine. It is also contraindicated in patients with acute myocardial infarction, marked anaemia, head trauma, cerebral haemorrhage, or closed angle glaucoma.
Pregnancy And Lactation
Headache may occur at the onset of treatment but will usually subside after a few days. If the headache persists dosage should be decreased. Other side effects include tachycardia, postural hypotension and syncope, cyanosis and methaemoglobinaemia.
