    Notes: Evidence has accumulated that nitric oxide is involved in the regulation of gastrointestinal motor activity. We investigated whether nitric oxide derived from a sustained-release isosorbide dinitrate (Cedocard retard) had an effect on gastric emptying and on subjective feelings.〈section xml:id="abs1-2"〉〈title type="main"〉Methods:Twelve healthy males aged 23–32 years received at weekly intervals, for 3 days twice daily, either 20 mg isosorbide dinitrate, 40 mg isosorbide dinitrate, or placebo, under random double-blind conditions. After a further dose on day 4, subjects ate a 1168 kJ semisolid meal, the emptying of which was recorded scintigraphically for 50 min.〈section xml:id="abs1-3"〉〈title type="main"〉Results:Neither dosage of isosorbide dinitrate had an effect on emptying which differed from the effect of placebo and the effects of the two dosages were the same. The radioactivity remaining in the stomach 50 min postprandially was 68.5% ± 4.5 S.E.M. after placebo, 65.4 ± 5.6% after 20 mg isosorbide dinitrate and 66.1 ± 4.4% after 40 mg isosorbide dinitrate. With 40 mg isosorbide dinitrate, all 12 subjects complained of persistent headache, whereas only slight headache was reported by 7 subjects on 20 mg isosorbide dinitrate and by 1 subject on placebo.〈section xml:id="abs1-4"〉〈title type="main"〉Conclusion:Twenty and 40 mg doses of sustained-release isosorbide dinitrate twice daily had no effect on the gastric emptying of a semisolid meal, but dose-dependently induced headaches.
