CERTIFICATION EVALUATION 2026
COMPLETE QUESTIONS AND ACCURATE
ANSWERS
◉ Efficacy
Answer: A drug's ability to produce the maximal desired response
◉ Efficacy
Answer: Is efficacy or potency more important to clinically
determine a drug's usefulness?
◉ Equi-potency
Answer: The relative doses of two drugs to get the same efficacy
◉ Equipotent, drug B
Answer: If you take 100mg of drug A and 10mg of dose B to get the
same effect, these drugs are considered _________
- Which drug is more potent?
,◉ Full Agonist
Answer: Produces a full response at full receptor occupancy
- If you bind 100% of receptors, you get 100% effects
- Ex.) Using methadone on a patient who has overdosed on a drug
◉ Partial Agonist
Answer: Binds to the receptor and partially activates the receptor
- Lesser response than a full agonist
- The response will not equal the maximal response of a full agonist
regardless of concentration
- Binding of 100% of receptors may only cause 50% effect
- Ex.) Using buprenorphine on a patient who as overdosed on a drug
◉ Antagonists
Answer: Drugs that block or reduce the action of agonists
- Ex.) Using Naloxone (narcan) on a patient who as overdosed on a
drug
◉ Competitive Antagonist
Answer: Type of antagonist that binds to the receptor and prevents
binding by other molecules
- When bound to the agonist, decreases the effectiveness of it
, - Ex.) Use of beta blockers to help limit epinephrine release/
increased HR
◉ Chemical Antagonism
Answer: Antagonist binding directly to the agonist
- Ex.) Pt is taking an antibiotic (ie cipro) and drinks milk (calcium
binds to the receptors that cipro is supposed to be acting on)
◉ Functional Antagonism
Answer: Antagonist that indirectly inhibits physiologic actions of the
agonist
- No activation of the receptor itself
- Ex.) Diabetic pt that is on insulin who adds a medication (ie
prednisone) which can raise blood sugar indirectly
- Solution: Increase insulin dose
◉ Reversible Antagonists
Answer: Antagonists that readily dissociate from their target
- Ex.) Ibuprofen
◉ Irreversible Antagonists
Answer: Antagonists that form a permanent, irreversible chemical
bond with their receptor
