How does the efficiency of a diclofenac patch decrease over time?
I wonder how the efficiency of a diclofenac patch decreases over time. E.g. if a patient wears a a diclofenac patch for 24 hours, how useful are the last 12 hours. Ideally I would like to see a curve (abscissa: time; ordinate: efficiency). Assume that the diclofenac patch is used to treat a lateral epicondyle of the humerus.
