Question

A patient walks out of the ophthalmologist's office and into bright sunlight after a comprehensive eye exam, for which he received a topical ophthalmic drug. The drug has not only dilated his pupils, but also impaired his ability to focus his eyes up-close. The drug this patient received was most likely classified as, or worked most similar to, which prototype?

a. Acetylcholine
b. Epinephrine
c. Homatropine
d. Isoproterenol
e. Pilocarpine
f. Propranolol

Answer 1

Homatropine is the drug that the patient likely received, as it causes dilation of the pupils and impairs near vision.

Step-by-step explanation:

The drug the patient received that caused dilation of the pupils and impaired ability to focus up-close is most likely classified as or works similarly to homatropine. Homatropine is a drug known as a muscarinic antagonist, which means it blocks the muscarinic receptors in the iris, leading to dilation of the pupils. It is commonly used during an eye exam to facilitate the examination of the retina and other parts of the eye.
