Which class of drugs is used to increase aqueous humor outflow in glaucoma treatment?

Beta-blockers
Carbonic anhydrase inhibitors
Prostaglandin analogs
Alpha-2 agonists

The correct answer is: Prostaglandin analogs

Prostaglandin analogs are the correct class of drugs used to increase aqueous humor outflow in glaucoma treatment. Prostaglandin analogs work by increasing uveoscleral outflow, which leads to a reduction in intraocular pressure. This class of medications is commonly used as first-line therapy due to their efficacy and once-daily dosing convenience. Beta-blockers, carbonic anhydrase inhibitors, and alpha-2 agonists are also classes of drugs used in glaucoma treatment, but they work through different mechanisms and are not primarily used to increase aqueous humor outflow like prostaglandin analogs. Beta-blockers reduce aqueous humor production, carbonic anhydrase inhibitors decrease aqueous humor production by inhibiting carbonic anhydrase enzyme, and alpha-2 agonists decrease aqueous humor production and slightly increase uveoscleral outflow.
