Impromidine (SK & F 92676) acts as a partial agonist on the isolated whole stomach of the rat.
The present secretory studies on the isolated stomach of the rat provide evidence that impromidine acts as a partial agonist at the histamine H2-receptors. It was found to be 100 times more potent than histamine but with a maximal response only 50% that obtained with histamine.
