Simultaneous measurement of gastric emptying of the soluble and insoluble components of a formulation using a dual isotope, gamma scintigraphic technique.

The gastric emptying of a soluble and an insoluble component of a capsule formulation has been monitored by gamma scintigraphy using a dual isotope technique. There was no significant difference between the emptying rates for the two components or between fasting and non-fasting conditions (P greater than 0.01).
