To determine the need for prophylactic nasogastric decompression following laparotomy and the influence of cimetidine, 200 consecutive patients who underwent major abdominal procedures were prospectively randomized into one of four limbs: no tube-placebo; no tube-cimetidine; tube-placebo; and tube-cimetidine. Patients were evenly distributed among these groups with respect to age, sex, alcohol and tobacco use, previous operations, and types of operations. There was significantly longer time until passage of flatus, bowel movement, and cessation of intravenous fluids in the tube group (p less than 0.05). Duration of postoperative stay increased from 11.4 to 14.1 days in the intubated patients (p less than 0.05). There was also significantly more pain with and frequency of swallowing, and nose/throat discomfort in the tube group. Nasogastric tubes reduced the incidence of vomiting from 28 in the no-tube group to 10 in the tube group (p less than 0.05), but most had only one or two episodes. Cimetidine did not affect either the incidence of vomiting or the duration of intubation, but was associated with a significant increase in pneumonias (p less than 0.05). Five patients without tubes initially, and seven patients with tubes had to have them inserted or replaced for vomiting or abdominal distention, which occurred equally in the placebo and cimetidine limbs. There were no cases of aspiration pneumonia, gastric dilatation, or wound dehiscence in the trial, and the four anastomotic leaks were divided equally between the tube and no-tube groups. The results indicated that prophylactic decompression was unnecessary in most patients and associated with increased morbidity and delayed return of gastrointestinal function. Cimetidine lowered nasogastric output on the first postoperative day (p less than 0.05), but did not prevent vomiting.

The results are reported from the treatment of 30 patients with the Bulgarian preparation biomet, which is a blocker of histamine H2-receptors. The treatment lasted 20 days with 3 X 20 mg biomet, after meals, and 400 mg in the evening before going to bed. Pains disappeared in 86,6 per cent with biomet treatment, pyrosis--in 95,8 per cent, eructation--in 95,3 per cent, nausea--in 84,7 per cent, vomiting--in 100 per cent of the patients, etc. (the clinical symptoms completely disappeared in 76,7 per cent after the treatment and were substantially reduced in 16,7 per cent). A statistically significant reduction of the basic parameters of gastric secretion and acid output occurred after biomet treatment as compared with the initial values. The fibroendoscopic study of the duodenal ulcer, after the treatment, revealed a complete epithelization in 52 per cent and diminished ulcer size--in 44 per cent. No pronounced adverse effects were observed during biomet treatment. The Bulgarian preparation biomet is fully equivalent to the English Cimetidine (the latter being more expensive) and should find a broad application in the treatment of duodenal ulcer.

The etiology, pathogenesis, diagnosis, and treatment of reflux esophagitis are reviewed. Reflux esophagitis is the subjective or objective response to gastroesophageal reflux (GER), which is defined as the entrance of gastroduodenal contents into the esophagus not associated with vomiting or belching. The pathogenesis of reflux esophagitis may involve a number of mechanisms, including changes in lower esophageal sphincter pressure, gastric volume, composition of the refluxate, esophageal acid clearance, and esophageal tissue resistance. The most common symptom of reflux esophagitis is heartburn. Regurgitation of fluid into the mouth, usually after bending or during the night, is an unequivocal symptom of GER. Treatment can be divided into three phases. Phase 1 involves the avoidance of certain foods and habits, elevation of the bed head, antacid, and alginic acid-antacid therapy. Phase 2 involves drug therapy with agents not yet approved by the FDA for this indication: bethanechol chloride, cimetidine, and metoclopramide hydrochloride. Bethanechol chloride 25 mg is generally given four times daily. Cimetidine is given in doses of 300-400 mg after meals and at bedtime. Metoclopramide hydrochloride is administered in doses of 10 mg before meals and at bedtime. Phase 3 is antireflux surgery. Clinical experience has shown that phase 1 therapy is successful for about 75% of all patients. Of the 25% that do not respond to phase 1 therapy, about 90% will respond to phase 2 therapy, leaving only 5-10% of all patients with this disorder who will require phase 3 treatment. Current data favor cimetidine and bethanechol over metoclopramide. The least proof of efficacy and the most frequent adverse side effects are seen with metoclopramide. Cimetidine and bethanechol appear to have similar efficacy and relatively infrequent side effects. Evidence confirming the superiority of cimetidine over bethanechol is lacking. Further research is needed to determine the optimal pharmacologic combinations and treatment regimens.

Long-term oral treatment with cimetidine is recommended to reduce vomiting in dogs with chronic gastritis. Despite this, few studies have specifically examined the plasma disposition and pharmacokinetics of cimetidine in dogs, particularly following repeated oral administration. The pharmacokinetics of cimetidine following oral administration as tablets was investigated in healthy dogs. Cimetidine was absorbed rapidly post-treatment (t(max) = 0.5 h). A mean absolute bioavailability of 75% was calculated following a single oral administration of 5 mg cimetidine/kg body weight. After intravenous administration, a plasma half-life of 1.6 h was calculated. Repeated oral administration at the recommended dose rate and regime (5 mg/kg body weight three times daily) for 30 consecutive days did not lead to any accumulation of cimetidine in plasma. Food intake concomitant with oral administration of cimetidine delayed (t(max) = 2.25 h) and decreased the rate and extent of absorption (AUC) by about 40%. Cimetidine was well absorbed in fasted dogs. Administration of food decreased the bioavailability of cimetidine by 40%. Cimetidine does not accumulate over time in plasma when administered long term to dogs.
