Lumina, Travatan, Xalatan are examples of which class of medications?

• A. Prostaglandin analogs
• B. Beta blockers
• C. Alpha agonists
• D. Anticholinergics

Answer: (A)

Prostaglandin analogs. Lumigan (bimatoprost), Travatan (travoprost), and Xalatan (latanoprost) are all prostaglandin F2α analogs used to lower intraocular pressure in glaucoma. They work by activating FP receptors to increase uveoscleral outflow of aqueous humor, which reduces IOP effectively. They’re typically given once daily and are favored as a first-line option because of their strong IOP-lowering effect and good tolerability. Common side effects include eye redness, slight iris color darkening, and eyelash growth. This class is distinct from beta blockers (which mainly cut aqueous production), alpha agonists (affect both production and outflow but have different profiles), and anticholinergics (which affect the eye in other ways and aren’t used as primary glaucoma therapy).
