Clinical notes

Applications:
  • Severe hypertension
Indication Notes:
Nitroglycerin is indicated for the prophylaxis of angina pectoris. The onset of action is not sufficiently rapid for this form to be useful in aborting an acute anginal episode.
Avoid In:

N/A

Contraindication Notes:
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.
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).
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.
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.
Nitroglycerin should not be used during pregnancy or lactation unless considered essential by the physician.
Nitroglycerin should be used with caution in patients who are predisposed to closed-angle glaucoma. As with other drugs for the treatment of angina pectoris, abrupt discontinuation of therapy may lead to exacerbation of symptoms. When discontinuing long term treatment, the dosage should be reduced gradually over several days, and the patient carefully monitored. The use of nitroglycerin during the early days of acute myocardial infarction requires particular attention to hemodynamic monitoring and clinical status to avoid the hazards of hypotension and tachycardia.
