A nurse administers warfarin (Coumadin) to a patient who is concurrently taking drug X, which also is highly protein bound. The nurse would anticipate that drug X will act at the receptor site as a
a. competitive agonist.
b. sympathomimetic.
c. competitive antagonist.
d. parasympathomimetic.
C
Because both drugs are highly protein bound, they will be competing for the same receptor site; they therefore are competitive antagonists, which increases the risk of toxicity.
Competitive agonists are drugs that compete for the same receptor site but do not potentiate the effects of the drugs.
A sympathomimetic effect mimics the effects of the sympathetic nervous system.
A parasympathomimetic effect mimics the effects of the PNS.
