This is a single-dose, randomized, two-period cross-over study with 72 healthy male and female volunteers. The investigational products will be given (after fasting overnight) at separate visits separated by 7 ± 3 days. Blood for pharmacokinetic analyses will be drawn pre-dose and at 5, 10, 15, 20, 25, 30, 40, 60, 75, 90, 105 minutes, as well as 2, 2.25, 3, 4, 5, 6, 8, and 12 hours after drug administration. Subjects will also be monitored to capture any adverse events that may occur. Bioequivalence will be assessed based on the single-dose pharmacokinetics of paracetamol, guaifenesin and phenylephrine, respectively
