We studied six dogs to determine the hemodynamic response to and pharmacokinetics of intravenous nitroglycerin (i.v. GTN) before and after a five-day treatment with placebo ointment. On the first study day, the major hemodynamic response to 21 micrograms/min i.v. GTN was an 11.4% +/- 5.6 (S.D.) fall in systolic blood pressure (SBP) from a control of 180 mmHg +/- 16 to 158 mmHg at 21 micrograms/min i.v. GTN. This finding was reproduced (a 12.6% +/- 5.6 fall in SBP) on the second study day. On the first day, the relationship between the arterial GTN concentration and the infusion rate was linear, the arterial t1/2 for GTN was short (1.9 min +/- 0.6) and there was an 80% arterial-venous extraction for GTN; these values were unchanged by five days of treatment with placebo. We conclude that this model is a sensitive and reproducible system for studying the in vivo effects of sustained drug treatment.
