    How important is distribution half-life? What is the formula to calculate it?

    It's critical for onset, loading dose, early exposure, and tissue targeting; in discovery it flags permeability and ranks tissue reach, while in development it guides loading strategies, early PK/PD timing, and sampling windows. 

    Distribution half-life can be derived by fitting IV or PO data to a compartment model (2–3).
