    One unstated fact that needs to be made clear: Reaching "steady state" requires *repeated* constant doses of the drug being taken, not a mere single dose followed by a number of half-lives.
    Taking a drug once will result in elimination until it's all gone from the body, never reaching "steady state".
    Another subtopic worthy of attention is the affect of an initial *"loading dose"* (typically a double dose) on kinetics and attainment of steady state at a serum level that is still determined based on the subsequent regular dose -- *not* based on the loading dose.
    Naproxen is a familiar nonprescription drug that has label directions that allow for an initial *double* (loading) dose followed by the normal dose at regular intervals of 12 hours.

      Yes to reach steady state there must be constant dosing, this was implied

      I was looking for this comment, because this was indeed not mentioned clearly in the video. Imagine a single dose getting you to steady state and that the level of steady state would depend on the size of the dose... That means if you get high once you would be high till eternity hahaha

      @@Guidus125 that needed to be explained? He said "you're taking the drug as prescribed", not "you took the drug".
      These videos are designed for medical students so it is expected people watching would have at least know these things. But it is understandable it may be hard for you if you have no medical background.

    Good lecture overall. Though probably not pertinent to USMLE questions, I would point out though that 1/2 life is NOT the time for which 1/2 the amount of drug is eliminated from the body, but the time needed to cut the the plasma concentration of a drug in half (and those measurements are not the same nor the same amount of time required necessarily ).... A clinically relevant clarification, though, again, maybe not important for USMLE purposes. I am a physician/pharmacist.
