PK

PK, or pharmacokinetics, refers to how a drug moves through the body over time. It involves four main processes: absorption (how the drug enters the bloodstream), distribution (how it spreads through tissues), metabolism (how it's broken down), and excretion (how it leaves the body). Understanding PK helps determine the right dosage and timing to ensure the medication is effective while minimizing side effects. In essence, PK studies provide critical information about what the body does to a drug, guiding safe and effective treatment.
