Formulation comprising testosteron undecanoate and castor oil

摘要

Disclosed is a pharmaceutical formulation in the form of a capsule for oral administration comprising testosterone undecanoate as an active ingredient dissolved in a pharmaceutically acceptable liquid carrier, characterised in that the liquid carrier comprises at least 50 % by weight of castor oil. The choice of castor oil as the liquid carrier, in conjunction with the choice of testosterone undecanoate as the androgen, makes for a solution which can comprise about 200-250 mg/ml of TU. This is a novel achievement for any orally administerable solution of testosterone. The solution may also contain a lipophilic surfactant such as lauroglycol.
