Pharmacokinetic (PK) data is a key requirement in the evaluation of new drugs and formulations. A quantitative measure of drug exposure is essential for the sound interpretation of pre-clinical efficacy studies. PK data is also requisite before toxicology studies can be performed.

PK samples are collected at various time points as per protocol and analyzed for drug concentrations. The time points depending on the nature of compound and route of administration.
