Which of the following drugs can be classified as a miotic for glaucoma treatment?

In the context of treating glaucoma, a miotic agent is one that causes constriction of the pupil. This is beneficial in glaucoma management because increasing the outflow of aqueous humor can help lower intraocular pressure.

Timolol, which is identified as the correct choice, is a non-selective beta-adrenergic antagonist (beta-blocker) that lowers intraocular pressure but does not function through the miotic mechanism. However, while Timolol is primarily recognized for its ability to reduce aqueous humor production, the drug is often included in discussions around glaucoma treatments due to its widespread use and effectiveness.

Atenolol and Acyclovir are not used in the treatment of glaucoma. Atenolol is a cardioselective beta-blocker used primarily for hypertension and cardiovascular conditions, while Acyclovir is an antiviral medication used to treat infections caused by certain viruses, including herpes simplex.

Phenylephrine, an alpha-agonist, works by increasing the pupil size (mydriasis) and is used as a dilating agent in ophthalmology but is not effective as a miotic agent for glaucoma.

In summary, while the answer provided may have been intended to reference an agent frequently associated with glaucoma therapy, Timolol’s classification
