The potential for a pharmacokinetic interaction between butorphanol nasal spray and cimetidine, under steady state conditions, was evaluated in 16 healthy male volunteers. Subjects received either a 1 mg butorphanol nasal spray every 6 h or a 300 mg cimetidine tablet every 6 h on days 1 4, the combination of two compounds every 6 h on days 5-8 and the original treatment as described in the firs...

The commonly accepted model for gastric emptying suggests that the 'antral mill' is responsible for the triturition and subsequent emptying of solid food from the stomach. Little is known about the contribution to solid emptying made by other digestive mechanisms such as acid-pepsin secretion. We have investigated the effect of inhibiting gastic secretion on the rate at which a solid test meal ...

A total of 9928 patients taking cimetidine and 9351 controls were recruited to a postmarketing drug surveillance study in Glasgow, Nottingham, Oxford, and Portsmouth. Takers were identified by the Prescription Pricing Bureau at Nottingham and by dispensing pharmacists at the other three centres. All but 1.2% of the takers and 1.6% of the controls were successfully followed up for one year durin...

PURPOSE To investigate the effects of probenecid and cimetidine on the pharmacokinetics of nemonoxacin in humans. METHODS Two independent, open-label, randomized, crossover studies were conducted in 24 (12 per study) healthy Chinese volunteers. In Study 1, each volunteer received a single oral dose of 500 mg of nemonoxacin alone or with 1.5 g of probenecid divided into three doses within 25 h...

The purpose of this single blind controlled multicentre trial was to compare the relative effectiveness of pirenzepine and cimetidine in healing endoscopically proven duodenal ulcers. One hundred and twenty six patients with duodenal ulcer were treated with a daily dose of 100 mg pirenzepine (50 mg each before breakfast and before the evening meal), and 128 patients were treated with 1000 mg ci...

the hematopoietic syndrome is anticipated when a dose of radiation greater than 100 cgy is received. the resulting clinical situation is life-threatening because of opportunistic infections and gradual decline in immune competency due to irradiation. because of evidence of a possible immunomodulatory role for cimetidine, an antagonist of histamine h2 receptors, we studied the effects of this dr...

The antiulcer effects of different tricyclic antidepressants (trimipramine, doxepin, imipramine, and amitriptyline) in comparison with those of cimetidine, pirenzepine and omeprazole were investigated in male rats with acute gastric ulcer. Acute gastric ulcer was induced by oral administration of O. 6N HCl solution, 1 mL/rat. Pretreatment of animals with doxepin, trimipramine, amitriptylin...

OBJECTIVE To test the hypothesis that the administration of cimetidine will modify the chronotropic response to exercise testing through a random clinical trial. METHODS The study selected 24 eligible healthy subjects, ages between 20 and 68 years, not athletes, who agreed to undergo cardiopulmonary exercise testing after the administration of placebo and 400 mg of cimetidine twice a day for ...

Fifteen patients with cystic fibrosis and pancreatic insufficiency were studied during four randomised seven day treatment periods in which they received only pancreatic supplement (Pancrelipase, 27 capsules per day) or supplement plus cimetidine (20 mg/kg body weight/24 h) or sodium bicarbonate (15 g/m2/24 h) alone or in combination. Dietary intake was not fixed but was restricted to foods of ...

Background. Functional dyspepsia is a common chronic disorder with non specific upper abdominal pain or discomfort. Different approaches with anti-secretory, spasmolytic, prokinetic and anti-inflammatory effects and most preferably reduction of visceral hypersensitivity seem logical. In this study, we compared the effectiveness of the four most drugs used for treatment of dyspepsia in children....
