Mechanism and action
Xalatan: Latanoprost is a prodrug ester hydrolysed by corneal esterases to its active free acid, which selectively binds the prostaglandin F (FP) receptor. Vardenafil: The mechanism is identical to original Levitra: vardenafil selectively inhibits PDE5 in penile smooth muscle, allowing cyclic GMP produced during sexual arousal to accumulate.
When Xalatan is preferred

When Vardenafil is preferred
Generic vardenafil shares the indication of the originator: erectile dysfunction in adult men.
