    When Half-Lives Lie: Drug Redistribution vs Elimination

    Melhor citação de When Half-Lives Lie: Drug Redistribution vs Elimination

    “

    Steady state is a beautiful equilibrium where the rate of drug going in equals the rate of drug coming out, typically reached after four to five half-lives. However, clinicians must distinguish between redistribution and elimination half-lives, as using the wrong one can lead to significant errors in predicting drug accumulation and therapeutic effect.
