Mechanism and action
Yaz: Yaz prevents pregnancy through three mechanisms: ovulation suppression (the dominant effect), thickening of cervical mucus to impede sperm transit, and changes in endometrial receptivity. Xalatan: Latanoprost is a prodrug ester hydrolysed by corneal esterases to its active free acid, which selectively binds the prostaglandin F (FP) receptor.
When Yaz is preferred
Yaz is approved for contraception in adult women requesting an oral contraceptive, treatment of premenstrual dysphoric disorder (PMDD), and treatment of moderate acne in women aged ≥14 who are also requesting contraception.
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.
