DMPK (Drug Metabolism and Pharmacokinetics) is critical for successful drug discovery and development because it provides essential knowledge about how a drug is absorbed, metabolized, and excreted by the body. This knowledge is necessary for determining the safety and efficacy of a drug, and for understanding the pharmacokinetic and pharmacodynamic properties that affect its therapeutic action. DMPK data allows researchers to gain a better understanding of the pharmacological properties of a drug, and to better predict its pharmacokinetic and pharmacodynamic behavior in humans. This knowledge is essential for designing successful clinical trials and optimizing the dose and delivery of a drug. Additionally, DMPK data can help determine the most appropriate route of administration, or whether a drug should be formulated for intravenous, oral, topical, or other delivery.
