Key differences
Trulicity belongs to Diabetes Treatment while Xalatan belongs to Eye Care and Ophthalmic Treatments. Indications, mechanisms and target populations differ. The comparison is most useful when a clinician has mentioned both medications and the patient wants to understand where each fits.
Mechanism and action
Trulicity: After subcutaneous injection, dulaglutide is gradually absorbed and circulates with greater than 99% albumin binding. Xalatan: Latanoprost is a prodrug ester hydrolysed by corneal esterases to its active free acid, which selectively binds the prostaglandin F (FP) receptor.
When Trulicity is preferred

When Xalatan is preferred
Xalatan is approved in adults and children for the reduction of elevated intraocular pressure in patients with chronic open-angle glaucoma or ocular hypertension.
