title: Prolonged plasma half-life after oral isosorbide dinitrate in patients with angina pectoris.
abstract: The plasma concentration of isosorbide dinitrate (ISDN) was monitored up to 24 h after a chronic oral dose of 60 mg in six patients with coronary artery disease. A terminal half-life of 7.7 +/- 2.6 h (mean +/- s.d.) was observed. The presence of this prolonged disappearance phase provided at least a partial explanation for the observed accumulation of ISDN in plasma after chronic dosing on a six hourly regimen.
