Abstract
In conscious cats provided with chronic gastric fistulas, metiamide, an H2-receptor antagonist, when given intravenously in a dose of 12 μmol/kg-hr, strongly inhibited gastric acid output stimulated maximally with histamine, pentagastrin, caerulein, insulin, urecholine, and peptone meal. Atropine sulfate administered in a dose of 0.288 μmol/kg-hr also inhibited gastric response to all these stimulants except histamine. These results can be explained by the hypothesis of interaction of various receptors of parietal cells, might be regarded as evidence for histamine mediation in the physiological stimulation of parietal cells, or may suggest the nonselectivity of the action of metiamide on parietal cell receptors.
