Mucinex First, Then Vicks
Treatment Sequences 1: Treatment A in Period 1, then Treatment B in Period 2 Test (Treatment A): Subjects received a single PO dose of 1 Mucinex® 600 mg guaifenesin ER bi-layer tablet administered with 240 mL of water. Reference (Treatment B): Subjects received a single PO dose of 15 mL (200 mg) Vicks Cough Syrup for Chesty Coughs Containing Guaifenesin every 4 hours (q4h) x 3 doses each administered with 240 mL of water. There was a 7 days washout period between each administration.

Population: PK Data Sets

Apparent first-order terminal elimination rate constant calculated from a semi-log plot of the plasma concentration versus time curve. The parameter was calculated by linear least-squares (LS) regression analysis using the maximum number of points (e.g. 3 or more non-zero plasma concentrations) in the terminal log-linear phase.

SECONDARY outcome

Timeframe: Upto Day 2

Mild = AE does not limit usual activities;subject may experience slight discomfort; Moderate = AE results in some limitation of usual activities; subject may experience significant discomfort; Severe = AE results in an inability to carry out usual activities; Probable = Most likely that the AE was caused by study drug; Possible = Reasonable suspicion that the AE was caused by the study drug; Unlikely = Slight but remote chance that the AE was caused by study drug but the balance of judgment is that it was most likely not due to the study drug.
