Glyceryl trinitrate ointment in angina pectoris

Glyceryl trinitrate ointment in angina pectoris.

Skin absorption of glyceryl trinitrate (GTN) has been recognized for a long time. The effect of GTN and a placebo ointment in prevention of chest pain has been assessed and compared by studying the exercise capacity in 17 patients with angina pectoris. The placebo cream was ineffective but the GTN ointment was found to have beneficial effect in relief of pain in 16 cases. This was established b...

Influence of glyceryl trinitrate during supine and upright exercise in patients with angina pectoris.

Efficacy of transdermal glyceryl trinitrate in the treatment of chronic stable angina pectoris.

A study was carried out to assess the efficacy of a new transdermal preparation of glyceryl trinitrate (Transiderm-Nitro 5) in the 24 hour prophylaxis of angina and to determine the duration of effect of a single patch application. Twelve men with chronic stable angina were studied in a randomised, placebo controlled, double blind trial. By serial treadmill exercise testing a therapeutic effect...

Assessment of dermal glyceryl trinitrate and isosorbide dinitrate for patients with angina pectoris.

Dermal nitrate preparations are claimed to be useful in the treatment of angina, as their slow absorption by-passing the liver leads to a sustained action. Ten patients with angina were exercised on a treadmill after dermal application of 16.64 mg glyceryl trinitrate or 100 mg isosorbide dinitrate or placebo. Exercise duration was significantly increased at one and three hours for both nitrate ...

Increased coronary sinus lactate concentration during pacing induced angina pectoris after clinical improvement by glyceryl trinitrate.

Ten patients with stable angina pectoris and obstructed coronary arteries (greater than 75% reduction in diameter) were studied before and during two periods of pacing, the second of which was preceded by sublingual administration of glyceryl trinitrate (mean dose 0.78 mg). Coronary sinus blood flow measurements and aortocoronary sinus blood sampling for metabolite determinations were carried o...
