Pharmacokinetics is the branch of pharmacology that studies how drugs move through the body. It involves the processes of absorption, distribution, metabolism, and excretion (ADME) of pharmaceutical compounds. Understanding pharmacokinetics helps in determining the appropriate dosages and timing for medications to achieve the desired therapeutic effects. The field of pharmacokinetics is crucial for drug development and clinical practice. By analyzing how a drug is absorbed into the bloodstream, how it is distributed to various tissues, how it is metabolized by the liver, and how it is ultimately excreted, healthcare professionals can optimize treatment plans for patients, ensuring safety and efficacy.
