The receptor subtype mediating rat alpha-calcitonin gene-related peptide (alpha-CGRP)-induced inhibition of gastric emptying of a non nutrient solution was tested in conscious rats using the CGRP1 receptor antagonist, CGRP 8-37, and the CCK antagonist, MK-329. Intravenous injection of alpha-CGRP (0.5 micrograms) decreased gastric emptying to 26.5 +/- 5.8% from 46.4 +/- 3.9% in vehicle-treated group. Intravenous injection of CGRP 8-37 (15 micrograms) did not influence gastric emptying but completely prevented alpha-CGRP inhibitory effect whereas the 47% delay in gastric emptying induced by intravenous cholecystokinin-8 (CCK, 0.25 microgram) was not modified. The CCK antagonist, MK-329 (1 mg) reversed CCK- but not alpha-CGRP-induced delay in gastric emptying. These results demonstrate that CGRP 8-37 is a specific tool to block alpha-CGRP inhibitory action on gastric motor function and suggest that gastric stasis elicited by peripheral injection of alpha-CGRP may involve an interaction with a CGRP1 receptor subtype.
