• Protein Binding
o Only part not bound crosses membrane.
▪ When two highly bound drugs are given it increases the
level of both drugs.
• Ex.-coumadin, thyroid both competing for plasma
proteins which increase level of free circulating drug.
• Elderly, keketic, decrease plasma albumin, MUST decrease dosage.
• PY450
o Substrate-an agent that is metabolized by an enzyme into a
metabolite and product and eventually excreted.
o Inhibitors-compete w/other drugs for a particular enzyme
affecting the metabolism (decreases) of the substrate and
decreases the excretion of the substrate and increases the
circulating drug.
o Inducers-competes w/other drugs for a particular enzyme
affecting metabolism of the substrate (increases) decreasing the
efficacy of the drug.
▪ Inhibitors Increase
▪ Inducers Decrease
• If a pt is on medication X and you administer
medication Y, that is an inducer or an inhibitor, you
know how it will affect substrate. You will have to
decrease the amount of drug given of inhibitor and
increase drug given of inducer
o Excretion (Need to know GFR)
