, Quiz: efficacy examples
Ans: -Agonist (Efficacy = 100)
-Partial Agonist (Efficacy = > 0 < 100)
-Antagonist (Efficacy = 0.0)
-Inverse Agonist (Efficacy = < 0)
Quiz: Agonist:
Ans: Compounds which give maximal response after receptor occupation and
activation.
-Example: Oxycodone
Quiz: Partial Agonists:
Ans: Compounds which activate the receptor but not at the maximal
response.
-Example Buprenorphine (Suboxone) or Buspirone

, Ans: Absorption: Drugs cross a barrier.
-Involves bioavailability or Quantity of drug reaching circulation/quantityof the
drug administered.
• Our own barriers such as skin and mucous membranes as well as food,
molecular weight, chemical, biological barriers, etc. reduce how much drug is
actually absorbed and available. IV route has 100% bioavailability. All other
routes <100%
Quiz: First pass metabolism
Ans: -reduces the concentration of a drug
• travels through digestive system & entering the liver.
• reducing the bioavailability of the drug
Quiz: rate is reduced by:
Ans: -Route (IV, PO, Rectum, etc.)
-Dosage (Concentration)
-Lipid Solubility
Quiz: Drugs that cross the BBB are _____________
