    • A process for producing polymorphic Form I of finasteride, 17B-(N-tert-butyl carbamoyl)-4-aza-5.alpha.-androst-1-en-3-one, in substantially pure form comprising the steps of: (1) crystallization from a solution of finasteride in a water immiscible organic solvent and 0% or more by weight of water, producing solvated and non-solvated finasteride in solution, such that the amount of organic solvent and water in the solution is sufficient to cause the solubility of the non-solvated form of finasteride to be exceeded and the non-solvated form of finasteride to be less soluble than any other form of finasteride in the organic solvent and water solution: (2) recovering the resultant solid phase; and (3) removing the solvent therefrom; wherein the water immiscible organic solvent is ethyl acetate or isopropyl acetate and the amount of water in the solvent mixture is below 4 mg./ml.

    • This invention is concerned with polymorphic forms of the compound N-�1(R)-�(1,2-dihydro-1-methanesulfonylspiro�3H-indole-3,4'-piperdin!-1'-yl)carbonyl!-2-(phenylmethyloxy)ethyl!-2-amino-2-methylpropanamide methanesulfonate which is a growth hormone secretagogue that is useful in food animals to promote their growth thereby rendering the production of edible meat products more efficient, and in humans, to treat physiological or medical conditions characterized by a deficiency in growth hormone secretion, and to treat medical conditions which are improved by the anabolic effects of growth hormone. The instant polymorphic forms have advantages over the other known forms of N-�1(R)-�(1,2-dihydro-1-methanesulfonylspiro�3H-indole-3,4'-piperdin!-1'-yl)carbonyl!-2-(phenylmethyloxy)-ethyl!-2-amino-2-methylpropanamide methanesulfonate in terms of thermodynamic stability and suitability for inclusion in pharmaceutical formulations. The present invention is also concerned with processes for preparing these polymorphic forms, pharmaceutical formulations comprising these polymorphic forms as active ingredients and the use of the polymorphic form of the compound and their formulations in the treatment of certain disorders.
