Yes: Zaditor (ketotifen) is longer-acting and has less tendency to lose its efficacy with continued use than opcon-a.
Created for people with ongoing healthcare needs but benefits everyone.

Zaditor (ketotifen): Zaditor seems to be more effective in my experience. Both of these are less effective than prescription alternatives (pataday, lastacaft, (alcaftadine) etc).
