Abstract
The invention comprises 2,17a -dimethyl-D 2-5a - androstene - 3,17b - diol - 4 - one and a process for the preparation thereof in which 2-hydroxymethylene - 4 - hydroxy - 17a - methyl - testosterone dissolved in an organic solvent is catalytically hydrogenated. Pharmaceutical compositions having anabolic activity and containing the above compound are administered orally in tablets, powders and pills or parenterally.
PROCESS FOR THE PREPARATION OF 1 (ALPHA), 24-DIHYDROXY-CHOLE-CALCIFEROLS, AS WELL AS DERIVATIVES AND PREPARATIONS THEREOF, AND PHARMACEUTICAL PREPARATIONS CONTAINING THESE COMPONENTS AS ACTIVE COMPONENTS.
PROCESS FOR THE PREPARATION OF AN 1-ARYLOXY-2-HYDROXY-3-ISOPROPYLAMINOPROPANE DERIVATIVE AND SALTS THEREOF, AND FOR THE PREPARATION OF (BETA) -ADRENOLYTICALLY ACTIVE PHARMACEUTICAL PREPARATIONS CONTAINING THESE PREPARATIONS.
PROCESS FOR THE PREPARATION OF 5H-DIBENZO (A, D) CYCLOHEPTES-5-CARBONAMIDES AND 10, 11-DIHYDRO-5H-DIBENZO (A, D) -CYCLOHEPTEEN-5-CARBONAMIDES, A METHOD FOR THE PREPARATION OF AN ANTI-PREPARATION METHOD ARRHYTHMIC AND ANTI-HYPERTENSIVE ACTION, AS WELL AS SUCH MEDICINAL PRODUCT.
PROCESS FOR THE PREPARATION OF PHARMACEUTICAL PREPARATIONS WITH BETA-ADRENOLYTIC ACTION CONTAINING AS THE ACTIVE INGREDIENT A 1-PHENOXY-2-HYDROXY-3-ALKYLAMINOPROPANE DERIVATIVE, AND SUITABLE COMPOUNDS FOR THIS.
