Dilatation of the coronary arteries also occurs. The relative importance of preload reduction, afterload reduction, and coronary dilatation remains undefined. Pharmacodynamics Dosing regimens for most chronically used drugs are designed to provide plasma concentrations that are continu-ously greater than a minimally effective concentration. This strategy is inappropriate for organic nitrates. Several well-controlled clinical trials have used exercise testing to assess the antianginal efficacy of continuously delivered nitrates.
In the large majority of these trials, active agents were indistinguishable from placebo after 24 hours or less of continuous therapy. Attempts to overcome tolerance by dose escalation, even to doses far in excess of those used acutely, have consistently failed. Only after nitrates have been absent from the body for several hours has their antianginal efficacy been restored.
The drug-free interval sufficient to avoid tolerance to isosorbide mononitrate has not been completely defined. In the only regimen of twice-daily isosorbide mononitrate that has been shown to avoid development of tolerance, the two doses of Ismo tablets are given 7 hours apart, so there is a gap of 17 hours between the second dose of each day and the first dose of the next day.
Taking account of the relatively long half-life of isosorbide mononitrate this result is consistent with those obtained for other organic nitrates. The incidence and magnitude of such phenomena have appeared, in studies of other nitrates, to be highly dependent upon the schedule of nitrate administration.
Could You Be At Risk? Pharmacokinetics In humans, isosorbide mononitrate is not subject to first pass metabolism in the liver.

None of these metabolites is vasoactive. The overall elimination half-life of isosorbide mononitrate is about 5 hours; the rate of clearance is the same in healthy young adults , in patients with various degrees of renal, hepatic, or cardiac dysfunction, and in the elderly. In a single-dose study, the pharmacokinetics of isosorbide mononitrate were dose-proportional up to at least 60 mg. Clinical Trials Controlled trials of single doses of Ismo tablets have demonstrated that antianginal activity is present about 1 hour after dosing, with peak effect seen from 1 to 4 hours after dosing.
In placebo-controlled trials lasting 2 to 3 weeks, Ismo tablets were administered twice daily, in asymmetric regimens with interdosing intervals of 7 and 17 hours designed to avoid tolerance.
One trial tested doses of 10 mg and 20 mg; one trial tested doses of 20 mg, 40 mg, and 60 mg; and three trials tested only doses of 20 mg. In each trial, the subjects were persons with known chronic stable angina, and the primary measure of efficacy was exercise tolerance on a standardized treadmill test. After initial dosing and for at least 3 weeks, exercise tolerance in patients treated with Ismo 20 mg tablets was significantly greater than that seen in patients treated with placebo, although there was some attenuation of effect with time.
Treatment with Ismo tablets was superior to placebo for at least 12 hours after the first dose i. Isosorbide Nombre de marca: La farmacia en linea accesible con el surtido grande, los precios bajos, el servicio de alta calidad y.
