A single dose of a drug was given to a 50 kg person at a dose level of 10 mg/kg. Blood and urine samples were collected periodically and the unchanged drug (parent drug) content in the samples was estimated. Calculate all possible pharmacokinetic parameters using the data given below. k, t1/2, Vd, AUC, ClT →→ using Blood data

k, t1/2 →→ using urine data
