Trial Outcomes & Findings for To Investigate the Gastrointestinal Behaviour of Two Triple Combination Products in Healthy Male Volunteers (NCT NCT03415243)

NCT ID: NCT03415243

Last Updated: 2019-06-24

Results Overview

Mean time to onset of gastric emptying in participants who did not vomit shortly (within 60 minutes) after study drug administration was evaluated by scintigraphic imaging, performed immediately after ingestion of the investigational drug formulation (radiolabeled with not more than 108 microcurie \[mcCi\] isotope-technetium-99m-diethylene-triamine-pentaacetate \[DTPA\]). Data images were analyzed in a time-lapse format and corrected for radioactive decay and background radiation. Regions of interest (ROI) included the stomach, proximal small intestine, distal small intestine and colon.

Measure
Treatment Group A
Participants received single oral dose; 1 sachet of Theraflu Daytime Severe Cold and Cough radiolabeled powder (that contained Acetaminophen 650 milligrams \[mg\] + Phenylephrine 10 mg + Dextromethorphan 20 mg) for oral solution reconstituted with 225 milliliters (mL) of hot water. Participants were instructed to consume the hot drink entirely within 30 seconds on Day 1 morning after an overnight fast and no food or drink was allowed until 4 hours post-dose.
Treatment Group B
Participants received single oral dose; 2 radiolabeled caplets of Theraflu ExpressMax Daytime Severe Cold and Cough (each caplet contained Acetaminophen 325 mg + Phenylephrine 5 mg + Dextromethorphan 10 mg) with 225 mL of room temperature non-carbonated water. Participants were instructed to consume all the water (225 mL) within 30 seconds on Day 1 morning after an overnight fast and no food or drink was allowed until 4 hours post-dose.

Data images were analyzed and corrected for radioactive decay and background radiation.
