Thank you ElMaestro. I share of your position.

There is a same situation to Nepafenac 0,1% and 0,3%. The FDA suggest bioequivalence studies with clinical endpoints, however there are data that indicating low plasma concentrations, but quantifiable, of nepafenac and amfenac observed in most individuals 2 and 3 hours post dose, respectively, after bilateral ocular topical dose 3 times per day nepafenac ophthalmic suspension 0.1%. Therefore, if there are levels measurable in human plasm a pharmacokinetic approach could be applied. I could be wrong, but I do not understand the reason for option clinical. If you or anybody else can explain, I really appreciate!

Regards!
