1. The pharmacokinetics of mifentidine, a new long acting histamine H2-receptor antagonist, were studied using two protocols. 2. In one study, on 5 different days six normal male subjects were given 2.5, 5, 10, or 20 mg mifentidine or placebo orally 60 min before starting a 3 h continuous gastric aspiration during which time blood samples were taken for(More)
Some drugs, including nonsteroidal antiinflammatory compounds, can be hemolytic in glucose-6-phosphate dehydrogenase-deficient patients. We have studied the potential hemolytic activity of feprazone, a nonsteroidal antiinflammatory compound in vitro and in vivo. Agents that may be hemolytic for glucose-6-phosphate dehydrogenase-deficient erythrocytes will(More)
In linear pharmacokinetics, the time course of the plasma concentration of a drug, Ct, is expressed by the sum of exponential terms, (formula; see text) This article proposes a new statistical criterion for discriminating between alternate polyexponential models. According to this new criterion, the model that best interprets a set of experimental data(More)
There have been few studies of the motility of the colon proximal to the rectosigmoid area. For this purpose we evaluated (1) fasting and postprandial transverse and sigmoid colon motor activity and (2) the effects of a new nonselective anticholinergic drug, cimetropium bromide, on transverse and sigmoid motor responses to eating. Two paired studies were(More)
There are at present few therapeutic alternatives to calcium channel blockers for the medical treatment of patients with nutcracker oesophagus. For this reason, we evaluated by means of a low-compliance manometric system the effect of a new anticholinergic compound, cimetropium bromide (10 mg intravenously), on oesophageal variables of eight patients with(More)
Gastric cytoprotective effects of vagotomy, PGE2 and antimuscarinic compounds (pirenzepine, atropine) were studied in the rat. Both pharmacological and surgical treatment prevented the gastric damage induced by intragastric administration of acetylsalicylic acid plus hydrochloric acid. The mechanisms of action are discussed.
In a 6-month, double-blind multicenter trial conducted over the winter, the effects of daily administration of ambroxol retard (75 mg) were compared with those of placebo in preventing exacerbations and improving symptoms and clinical signs in chronic bronchitis patients. The trial was completed by 110 patients in the ambroxol group and by 104 in the(More)
The pharmacokinetic profiles of cimetropium bromide, after either intravenous injection of 10 mg or oral ingestion of 200 mg, were determined in eight healthy volunteers. After intravenous administration, the plasma levels and urinary excretion indicated that the drug is distributed and eliminated at a rapid rate (terminal half-life, 50 +/- 8 min) and that(More)
Most drugs are ineffective for the long-term treatment of irritable bowel syndrome (IBS). The beneficial effects of medical treatment of IBS are poor and last for only a relative short time. Over a period of 6 months, we investigated the effectiveness of cimetropium bromide, a new antimuscarinic compound, in patients with IBS. Forty-eight patients were(More)
Fifty patients (with non-ulcer dyspepsia) were admitted to a double-blind, placebo-controlled trial to study the effects of pirenzepine (100 mg/daily) on non-ulcer dyspepsia. Ten patients did not complete the trial. After 4 weeks of treatment, statistically significant improvement (P less than 0.001) was observed endoscopically in the pirenzepine group. The(More)
