Androderm,a once daily skin patch, called a transdermal delivery system, is a testosterone replacement therapy in males with a deficiency or absence of endogenous testosterone. It delivers consistent, controlled concentrations of testosterone through the skin.
The new testosterone patch which comes in smaller size and lower-dose provides 20% reduction in the active ingredient from the original strength in a smaller patch size.
The approval occured following a trial that demonstrated 97% of the subjects achieved testosterone concentrations within the normal range after 28 days of daily therapy.
