Tolerance to isosorbide dinitrate: rate of development and reversal.
The circulatory response and plasma concentrations of isosorbide dinitrate (ISDN) were determined in 10 patients with chronic, stable angina after administration of 5 mg of sublingual ISDN during the control stage, after 48 hr of therapy with 15 mg of ISDN orally every 6 hr, and subsequently after a 48 hr period when ISDN was substituted by placebo four times daily. Initially, sublingual ISDN i...
متن کاملTolerance to the circulatory effects of oral isosorbide dinitrate. Rate of development and cross-tolerance to glyceryl trinitrate.
The effects of 15, 30, 60 and 120 mg of isosorbide dinitrate (ISDN) on systolic blood pressure (SBP) and heart rate (HR) were compared after acute oral administration and during sustained therapy four times daily with ISDN in six patients. After any given dose, plasma ISDN levels were higher during sustained therapy than during acute therapy. The average peak reduction in standing SBP occurred ...
متن کاملPreventive administration of intravenous N-acetylcysteine and development of tolerance to isosorbide dinitrate in patients with angina pectoris.
BACKGROUND Development of tolerance to organic nitrates may be related to depletion of sulfhydryl groups in vascular smooth muscle. N-Acetylcysteine (NAC), a sulfhydryl donor, has been reported to potentiate the effect of nitroglycerin and reverse tolerance in humans. However, its ability to prevent or delay the development of nitrate tolerance in patients with angina pectoris has not been esta...

متن کاملEndoscopic variceal pressure measurements: response to isosorbide dinitrate.
An endoscopic pressure sensor has been evaluated in the measurement of oesophageal variceal pressure and its response to drug ingestion. The variceal pressure showed a highly significant correlation with the splenic pulp pressure (r = 0.97) in six patients with liver disease of diverse aetiology and with hepatic venous wedge pressure (r = 0.92) in eight alcoholic cirrhotic men. Intraduodenal in...
