[Inhibition of stimulated gastric secretion with simultaneous administration of cimetidine and somatostatin].

In four gastric fistula dogs we studied the effect of cimetidine (5 mg/kg/h) and somatostatin (10 microgram/kg/h), alone or in combination, on gastric secretion stimulated by histamine (160 microgram/kg/h) or pentagastrin (6 microgram/kg/h). Acid and pepsin output after histamine stimulation was more reduced by cimetidine than after pentagastrin stimulation. Somatostatin showed an inhibitory effect only after pentagastrin stimulation. The most effective reduction, both on the degree of inhibition and on duration after cessation of the inhibitors, was seen after the combination of cimetidine/somatostatin. These results give some clinical aspects for the use of these two agents.
