Response to pentagastrin in man. III. Comparison of two formulations

Gastric secretion has been studied in response to the standard preparation of pentagastrin and a new, more stable preparation (pentagastrin meglumine). The sensitivity to, and maximal outputs of acid and pepsin elicited by, the two preparations of pentagastrin did not differ. However, the pentagastrin meglumine evoked a better sustained acid secretion with all dose rates than did the standard pentagastrin.
