Xalatan: Latanoprost ist ein Prodrug-Ester, der durch korneale Esterasen zu seiner aktiven freien Säure hydrolysiert wird, welche selektiv an den Prostaglandin-F-(FP)-Rezeptor bindet. Sitagliptin: Sitagliptin hemmt reversibel DPP-4, die Serinprotease, die für den schnellen Abbau von Glucagon-like Peptid 1 (GLP-1) und glukoseabhängigem insulinotropen Polypeptid (GIP) verantwortlich ist.
