Comprehensive Nursing Pharmacology Q 223
Which of the following drugs might be given to relieve pain from corneal abrasions?
A. Proparacaine hydrochloride (Alcaine)
B. Timolol maleate (Timoptic)
C. Betaxolol hydrochloride (Betoptic)
D. Levobunolol hydrochloride (Betagan)
Correct Answer: A. Proparacaine hydrochloride (Alcaine)
This is the only drug listed that is an anesthetic eye preparation. ALCAINE (proparacaine hydrochloride ophthalmic solution) (Proparacaine Hydrochloride) Ophthalmic Solution is indicated for topical anesthesia in ophthalmic practice. Representative ophthalmic procedures in which the preparation provides good local anesthesia include measurement of intraocular pressure (tonometry), removal of foreign bodies and sutures from the cornea, conjunctival scraping in diagnosis and gonioscopic examination; it is also indicated for use as a topical anesthetic prior to surgical operations such as cataract extraction.
Option B: Ophthalmic timolol is used to treat glaucoma, a condition in which increased pressure in the eye can lead to the gradual loss of vision. Timolol is in a class of medications called beta-blockers. It works by decreasing the pressure in the eye. Timolol eye drops and gel-forming solution control glaucoma but do not cure it. Continue to use timolol even if you feel well. Do not stop using the medication without talking to a doctor.
Option C: Ophthalmic betaxolol is used to treat glaucoma, a condition in which increased pressure in the eye can lead to the gradual loss of vision. Betaxolol is in a class of medications called beta-blockers. It works by decreasing the pressure in the eye.
Option D: Ophthalmic levobunolol is used to treat glaucoma, a condition in which increased pressure in the eye can lead to a gradual loss of vision. Levobunolol is in a class of medications called beta-blockers. It works by decreasing the pressure in the eye.
