A female client complains of periorbital aching, tearing, blurred vision, and photophobia in her right eye. Ophthalmologic examination reveals a small, irregular, nonreactive pupil - a condition resulting from acute iris inflammation (iritis). As part of the client’s therapeutic regimen, the physician prescribes atropine sulfate (Atropisol), two drops of 0.5% solution in the right eye twice daily. Atropine sulfate belongs to which drug classification?
a. Parasympathomimetic agent
b. Sympatholytic agent
c. Adrenergic blocker
d. Cholinergic blocker

Answer D.
Atropine sulfate is a cholinergic blocker. It isn’t a parasympathomimetic agent, a sympatholytic agent, or an adrenergic blocker.
