Summary

This clinical study will be conducted to characterize the gastrointestinal transit of two multi-symptoms formulations by inclusion of a radiolabel marker.

Eligibility Criteria

Inclusion Criteria

  • Evidence of a personally signed and dated informed consent document indicating that the subject has been informed of all pertinent aspects of the study before any assessment is performed.
  • Healthy male participants who, at the time of screening, are between the ages of 21 and 45 years, inclusive.
  • Participants who are willing and able to comply with scheduled visits, treatment plan, bio-imaging procedure, laboratory tests and other study procedures.
  • Healthy participant which is defined as in general good physical health, as judged by the investigator and no clinically relevant abnormalities identified by a detailed medical history, full physical examination, including blood pressure and pulse rate measurement, 12-lead Electrocardiogram (ECG) or clinical laboratory tests.
  • Body Mass Index (BMI) of 17.5 to 30.5 kilogram per meter square (kg/m2); and a total body weight >50 kg (110 lbs)

Exclusion Criteria

  • Participants who are investigational site staff members directly involved in the conduct of the study and their family members, site staff members otherwise supervised by the investigator, or participants who are GSK employees directly involved in the conduct of the study.
  • Participation in other studies involving investigational drug(s) within 30 days prior to study entry and/or during study participation.
  • Acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the participant inappropriate for entry into this study.
  • Known or suspected intolerance or hypersensitivity or contraindication to the study materials (or closely related compounds) or any of their stated ingredients.
  • Participant with known allergy or intolerance to any of the contents of the standard meals.
  • Participant is vegetarian.
  • Unwilling or unable to comply with the Lifestyle guidelines described in this protocol.
  • Use of prescription or non-prescription drugs and dietary supplements within 14 days or 5 half-lives, whichever is longer, prior to the first dose of investigational product that are deemed by the investigator to have a potential impact on the study objectives results.
  • Evidence or history of clinically significant laboratory abnormality, hematological, renal, endocrine, pulmonary, cardiovascular, hepatic, psychiatric, neurologic, or allergic disease within the last 5 years that may increase the risk associated with study participation.
  • A positive urine drug screen, breath alcohol test or urine cotinine test during Screening or on Day -1 of the study.
  • Any condition possibly affecting drug absorption (e.g., gastrectomy)
  • A history of current or relevant previous non-self-limiting gastrointestinal disorders peptic ulcer disease and/or gastrointestinal bleeding.
  • Currently suffering from disease known to impact gastric emptying, e.g. migraine, insulin-dependent diabetes mellitus.
  • The participant has had radiation exposure from clinical trials, including from the present study, and from therapeutic or diagnostic exposure, but excluding background radiation, exceeding a target organ (colon) dose of 50 mSv (5 rems) from a single dose within the last 30 days or a cumulative dose of 150 mSv (15 rems) in the last 12 months. No participant whose occupation requires monitoring for radiation exposure will be enrolled in the study.
  • Participants who have been exposed to ionising radiation in excess of 10 mSv (whole body effective dose) above background over the previous 3 years period as a result of occupational exposure or previous participation in research studies. Clinically justified (therapeutic or diagnostic) exposures are not included in this calculation.
  • Renal disease or impaired renal function at screening as indicated by abnormal levels of serum creatinine or urea or t
