Glyceryltrinitrate is a smooth muscle relaxant with vascular effects manifested predominantly by venous dilation with pooling.
The major beneficial effect of glyceryltrinitrate in angina pectoris is a reduction in myocardial oxygen consumption secondary to vascular dilation with resultant reduction in cardiac preload and afterload.
Continuous glyceryltrinitrate infusion at 3.1 to 4.0 mg/hr for 2-4 weeks in 36 patients resulted in an average methaemoglobin level of 0.2%, which was comparable to the level observed in patients receiving placebo.
