Mechanism and action
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. Norvasc: Amlodipin blockiert selektiv L-Typ-Calciumkanäle in der glatten Gefäßmuskulatur, reduziert den transmembranen Calciumeinstrom und bewirkt eine periphere arterielle Vasodilatation.
When Xalatan is preferred

When Norvasc is preferred
