Comparison of dose-response curves between acid and pepsin to betazole hydrochloride in the dog with gastric fistula.
Secretory responses to subcutaneously or intravenously administered betazole hydrochloride of graded doses were compared between acid and pepsin in the dog with gastric fistula. Although the dose related increments in acid and pepsin outputs were parallel in the range of lower doses than 2.0 to 3.0 mg/kg body weight of betazole hydrochloride, higher doses caused in decrease in pepsin output, but did not in acid output. It was pointed out that the dose of betazole hydrochloride that stimulates acid secretion maximally dose not correspond to the maximal stimulation for pepsin secretion in the dog.
