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)
Characteristics of inflammatory bowel diseases have been hypothesized to resemble those of the syndrome of intestinal ulceration induced in the rat by non-steroidal anti-inflammatory compounds. However, no systematic studies have been undertaken to examine this possibility. Therefore, we have studied the influence of some pharmacological agents, such as(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)
The colonic motor response to eating requires cholinergic transmission. Recent studies have identified two subclasses of muscarinic receptor, the M1 and the M2 subtype. The aim of this study was to evaluate the muscarinic receptor subtype responsible for mediating the gastrocolonic response. Spike potential (SP) activity and intraluminal pressure were(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)
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)
Oral beta 2-agonists (carbuterol, pirbuterol, procaterol, bitolterol, clenbuterol) are drugs widely used as bronchodilators. The efficacy and selectivity of bronchodilators drugs depend on their intrinsic pharmacological properties and on the route of administration. The characteristics of the oral route are easy usage, precise dosage and assured effects.(More)
Fifty-five outpatients with chronic duodenal erosions and no previous ulcer history were treated, in a double-blind fashion, with either pirenzepine (50 mg twice daily) or ranitidine (150 mg twice daily) for 6 weeks. The drugs were equally effective in inducing symptomatic relief. At endoscopic control, 70.4% of subjects in the pirenzepine group and 39.3%(More)
Ten patients with endoscopically proven duodenal ulcers participated in a double-blind, placebo-controlled, cross-over trial to investigate the effect of pirenzepine on nocturnal gastric acid secretion. Pirenzepine, 50 mg orally at bedtime, inhibited acid secretion all night long: the overall volume secreted and acid output (midnight to 7 a.m.) were(More)
The purpose of the present study was to compare the effectiveness of pirenzepine and carbenoxolone in accelerating the healing of chronic gastric ulcer. Sixty-six out-patients with endoscopically proven gastric ulcer, without major systemic diseases, were admitted to the study. Patients were randomly allocated to either pirenzepine, 50 mg three times a day(More)
