A pharmacology student asks the instructor what an accurate description of a drug agonist is. What is the instructors best response?
- A. A drug that reacts with a receptor site on a cell preventing a reaction with another chemical on a different receptor site
- B. A drug that interferes with the enzyme systems that act as catalyst for different chemical reactions
- C. A drug that interacts directly with receptor sites to cause the same activity that a natural chemical would cause at that site
- D. A drug that reacts with receptor sites to block normal stimulation, producing no effect
Correct Answer: C
Rationale: Agonists are drugs that produce effects similar to those produced by naturally occurring neurotransmitters, hormones, or other substances found in the body. Noncompetitive antagonists are drugs that react with some receptor sites preventing the reaction of another chemical with a different receptor site. Drug-enzyme interactions interfere with the enzyme systems that stimulate various chemical reactions.
