  • Patent number: 6977083
    Abstract: 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.

  • Patent number: 6855836
    Abstract: The invention relates to 17-methylene steroids, process for their production and pharmaceutical compositions that contain these compounds. The compounds according to the invention have a hybrid-type profile of action in the sense that they act as inhibitors of 5?-reductase and simultaneously as gestagens. They are therefore suitable for treating diseases that are the result of elevated androgen levels in certain organs and tissues in men and women. Together with other hormonal substances, such as an estrogen, testosterone or a strong androgen, the compounds according to the invention are suitable as contraceptive agents for women and for men.

  • Patent number: 6815469
    Abstract: A biodegradable, injectable oligomer-polymer composition is described, which consists of a combination of at least two biologically degradable inert materials and at least one biologically active ingredient. The inventive, oligomer-polymer composition coagulates when injected into the body of a mammal and forms an implant, from which the biologically active ingredient is released. The rate of release can be adjusted by controlling the type and amount of the ingredients of the oligomer-polymer composition.

  • Patent number: 6290931
    Abstract: A homogeneous steroid-containing preformulation for production of solid and semi-solid pharmaceutical preparations containing a uniform constant dosage of at least one steroid in a range from 0.001 to 1 percent by weight is described. This steroid-containing preformulation contains of from 0.001 to 50 percent by weight of the at least one steroid. The homogeneous steroid-containing preformulation is made by a method including dissolving the at least one steroid in a solvent to form a dispersant; dispersing an adjuvant consisting of adjuvant particles in the dispersant in a mass ratio of the adjuvant to the at least one steroid of 1:1 to 1000:1 to form a suspension; and creating a spray-mist of the suspension so as to evaporate and remove the solvent from the suspension and thus to form a dried particulate which includes steroid-containing particles. The droplets in the spray mist have a droplet diameter greater than a mean diameter of the adjuvant particles.

  • Patent number: 6245756
    Abstract: Pharmaceutical preparations containing selected steroid compounds and methods of treating estrogen deficiency in the central nervous system (CNS) without influencing other organs or systems are described. These steroids have selective neurotropic estrogen-like transcription action in contrast to the systemically acting natural and synthetic estrogen compounds, such as 17&agr;-estradiol. The selected steroids surprisingly have a selective influence on the transcription estrogen-dependent gene in the CNS and cause changes of physiological parameters as well as CNS-specific transcription effects in the dosages used with no biological effects in reproductive system tissues. They have CNS specific transcription effects at those dosages at which neither 17 &bgr;-estradiol nor 17&agr;-estradiol had any action and the transcription estrogen-dependent gene in the CNS is not influenced by secondarily formed 17&bgr;-estradiol.
