Publication number: 20070078091Abstract: This invention relates to pharmaceutical combinations for compensating for an absolute and relative testosterone deficiency in men with simultaneous prophylaxis for the development of a benign prostatic hyperplasia (BPH) or prostate cancer. The combinations according to the invention contain a natural or synthetic androgen in combination with a gestagen, an antigestagen, an antiestrogen, a GnRH analog, a testosterone-5?-reductase inhibitor, an ?-andreno-receptor blocker or a phosphodiesterase inhibitor. In comparison to the combinations according to the invention, any active ingredient by itself cannot achieve the desired goal.Type: ApplicationFiled: September 8, 2006Publication date: April 5, 2007Inventors: Doris Hubler, Michael Oettel, Lothar Sobek, Walter Elger, Abdul-Abbas Al-Mudhaffar

Publication number: 20060142257Abstract: A formulation for male contraception comprising a progestin possessing both estrogenic and androgenic properties is remarkably effective for spermatogenesis suppression in males. The progestin Norethisterone (NET), particularly its derivatives Norethisterone acetate and Norethisterone enanthate in sufficient doses induce oligozoospermia or azoospermia in males. Formulations further comprising an androgen, such as a testosterone derivative such as a testosterone ester, particularly testosterone undecanoate, are especially effective male contraceptive formulations.Type: ApplicationFiled: February 17, 2006Publication date: June 29, 2006Inventors: Eberhard Nieschlag, Axel Kamischke, Michael Oettel, Alexander Ruebig, Ekkerhard Schillinger, Ursula-Friederike Habenicht

Patent number: 7053077Abstract: The invention relates to the use of biogenic estrogen sulfamates for the oral discontinuous application for hormone replacement therapy (HRT). The discontinuous administration takes place in intervals ranging from 2 to 40 days. The invention also provides the additional application of gestagens, preferably continuously in the form of an implant or in the form of an intrauterine releasing system (IUD). Estrone sulfamate, estradiol sulfamate or an N-acyl sulfamate of estrone, estradiol or estriol having up to 7 C-atoms in the acyl chain, or a combination comprised of two or more of said active ingredients are used as biogenic estrogen sulfamates.Type: GrantFiled: May 13, 1999Date of Patent: May 30, 2006Assignee: Schering AGInventors: Walter Elger, Pekka Lähteenmäki, Matti Lehtinen, Gudrun Reddersen, Holger Zimmermann, Michael Oettel, Sigfrid Schwarz

Patent number: 6977083Abstract: 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.Type: GrantFiled: September 30, 1999Date of Patent: December 20, 2005Assignee: Jenapharm GmbH & Co.

Patent number: 6670350Abstract: A method of administering dienogest to a women in high dosages for reducing the body of the breast is described. The dosage should be at least ten times the effective dosage for inhibiting ovulation in the women. A pharmaceutical composition for use in the method is also described. Furthermore, retrogression of mastopathic changes in the body of the breast can be brought about. Dienogest is also outstandingly suitable for the prophylaxis of mastopathies. In high dosages, dienogest prevents the formation of mastopathic changes in the body of the breast.Type: GrantFiled: January 14, 2002Date of Patent: December 30, 2003Assignee: JenaPharm GmbH & Co.

Patent number: 6432939Abstract: This invention describes 17&agr;-hydroxy-4-androstene-3-one and its derivatives of the general formula I a method for producing these compounds and pharmaceuticals containing these compounds. The compounds according to the invention can be used for regulating spermatogenesis and for hormone replacement therapy in males by stimulating the inhibin-B secretion by the Sertoli cells. The increased inhibin-B concentration suppresses spermatogenesis in the testicles as it inhibits excretion by the hypophysis of follicle-stimulating hormone (FSH) that is essential in spermatogenesis.Type: GrantFiled: November 10, 2000Date of Patent: August 13, 2002Inventors: Michael Oettel, Jens Berlau, Wolfgang Römer, Gerhard Schreiber

Patent number: 6245756Abstract: 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.Type: GrantFiled: February 19, 1999Date of Patent: June 12, 2001Assignee: Jenapharm GmbH & Co. KGInventors: Vladimir Patchev, Michael Oettel, Sigfrid Schwarz, Ina Thieme, Wolfgang Roemer

Patent number: 6225299Abstract: The pharmaceutical composition, especially for treating skin with seborrhea, Acne vulgaris and androgonically conditioned alopecia, contains a hormonal agent including the gestogen, dienogest, or a combination of dienogest and an estrogen, as active ingredient. Methods for treatment of this type of skin condition include topical application of the composition including the dienogest which results in an outstanding sebosuppression, a drastic reduction of androstandiol glucuronide and a moderate competitive blockage of androgen receptor sites. Galenic formulations are described which limit and/or prevent the permeation of the active ingredient through the skin.Type: GrantFiled: December 23, 1998Date of Patent: May 1, 2001Assignee: Jenapharm GmbH & Co.

Patent number: 6214377Abstract: The use of melatonin for the production of peroral pulsatile forms of medications assures the safeguard of an effective level of the medical substance of melatonin in the blood, and which realize a relatively short invasion phase with a controlled delivery in comparison to conventional forms of medication containing melatonin, and which simultaneously exclude the known side effects. A control of the delivery of the melatonin is effected which is associated with the precise adaptation to the illness episodes or the pain attacks of certain illnesses, which can be treated prophylactically and therapeutically with the active agent melatonin.Type: GrantFiled: December 5, 1995Date of Patent: April 10, 2001Assignee: Jenapharm GmbHInventors: Michael Dittgen, Sabine Fricke, Thomas Gräser, Hermann Osterwald, Michael Oettel, Theodor Hermann Lippert
