Glyceryl trinitrate relieves angina pectoris by reduction of cardiac work and dilation of the coronary arteries. In this way, not only is there a lessening in arterial oxygen requirement but the amount of oxygenated blood reaching the ischaemic heart is increased.
The pharmacokinetics of glyceryl trinitrate are complex; venous plasma levels of the drug show wide and variable fluctuations and are not predictive of clinical effect. In a human pharmacodynamic study, pharmacological activity had commenced one minute after dosing and was obvious by two minutes.
None stated.
