The method of making a bioadhesive tablet for controlling testosterone blood
level, especially in elderly men suffering from partial androgen deficiency, includes
spray-drying an alcoholic solution or suspension of testosterone and at least one
testosterone ester, preferably in a ratio of 1:10 to 1:1.5, separately or together,
with an organic polymer and optionally one or more auxiliary ingredient to form
an active ingredient premix. Then various other auxiliary ingredients are mixed,
as needed, with the active ingredient premix to form the bioadhesive tablet with
an active ingredient layer and an adhesive layer. The active ingredient layer contains
an effective amount of the active ingredient premix. The adhesive layer includes
auxiliary ingredients including the bioadhesive polymer. The bioadhesive tablet
may be buccally administered to provide a predetermined timed release profile of
testosterone, advantageously varying according to a circadian rhythm.
