Brief summary

For six hours following drug administration, subjects will rate the severity of specific symptoms. At the end of the six hour study, subjects will rate the overall effectiveness of the product.

Detailed description

A six-hour study to evaluate multiple early efficacy endpoints in loperamide-simethicone therapy to help identify speed of onset of symptomatic treatment of acute nonspecific diarrhea (ANSD).

Interventions

DRUGloperamide-simethicone

Four caplets containing 2 mg loperamide HCl and 125 mg of simethicone each, administered orally with 4-8 oz. of water according to the labeled directions of the currently marketed product (i.e., 2 caplets after first loose stool, followed by 1 caplet after each subsequent loose stool, not to exceed 4 caplets in 24 hours). The treatment period will last six hours.

DRUGmatching placebo

Four placebo caplets matching the caplets in Arm 1, administered orally with 4-8 oz. of water according to the labeled directions of the currently marketed product (i.e., 2 caplets after first loose stool, followed by 1 caplet after each subsequent loose stool, not to exceed 4 caplets in 24 hours). The treatment period will last six hours.
