Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is designed to compare the pharmacokinetics of four products used for treatment of acute diarrhea.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study will be a single dose, randomized, four -way, four-sequence crossover study in 24 healthy subjects, with equal numbers of males and females (minimum of 10 of either gender). Subjects who drop out will not be replaced. The four doses of medication given in the study (a single dose in each of the four study periods) will be separated by a washout period of at least 7 calendar days. In each study period, 17 blood samples for pharmacokinetic analysis will be taken over 12 hours. Blood samples will be centrifuged and concentrations of thiorphan (the active metabolite) in plasma will be measured using a validated chromatographic assay. Pharmacokinetic parameters will be calculated from plasma concentration data.

* Non- or ex-smokers; an ex-smoker being defined as someone who completely stopped smoking for at least 12 months before day 1 of this study.
* Clinical laboratory values within the laboratory's stated normal range; if not within this range, they must be without any clinical significance
* Have no clinically significant diseases captured in the medical history or evidence of clinically significant findings on physical examination and/or clinical laboratory evaluations Has signed and dated the informed consent document, indicating that the subject has been informed of all pertinent aspects of the study
* Willingness and ability to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures

Exclusion Criteria

* Seated pulse rate and blood pressure within protocol-specified parameters.
* Relationship to persons involved directly with the conduct of the study (i.e., principal investigator; sub-investigators; study coordinators; other study personnel; employees or contractors of the sponsor or Johnson \& Johnson subsidiaries; and the families of each)
* Females who are pregnant or are lactating
