Measure
Test Drug/Reference Drug
Participants received new paracetamol suspension (Test drug) orally as a single 42 milliliter (mL) (1 gram \[g\] paracetamol) dose in treatment period 1. In treatment period 2, participants received marketed paracetamol suspension (Reference drug) orally as a single 42 mL (1 g paracetamol) dose. There was a washout period of 3 days between two treatment periods.
Reference Drug/Test Drug
Participants received marketed paracetamol suspension (Reference drug) orally as a single 42 mL (1 g paracetamol) dose in treatment period 1. In treatment period 2, participants received new paracetamol suspension (Test drug) orally as a single 42 mL (1 g paracetamol) dose. There was a washout period of 3 days between two treatment periods.

AUC (0-inf) = AUC (0-tlast) + Clast/ λz, where Clast is the concentration at the last measurable sampling time point and λz is the terminal elimination rate constant. Blood samples were collected at the indicated time points for for the analysis of AUC (0-inf). PK parameters were calculated by standard non-compartmental analysis.
