Understanding the kinetics of how a drug is removed from the body is foundational for creating and adjusting rational dosage plans tailored to individual patient needs. Three key pharmacokinetic parameters must be comprehended: bioavailability (F), volume of distribution (Vd), and clearance (CL). The first two have been previously discussed. Drug Elimination Drug elimination comprises both … Read more
