The gastric secretory response to pentagastrin and histamine administered jointly in maxiumum does by the subcutaneous route and in intravenous infusion, and  in lower doses in infusion has been compared to the response to each of the two drugs administered by itself. No potentiating action was observed, some additive action was found on infusion of the drugs and even this action was confined to the lowest dose-levels.
