The invention further relates to a process for the synthesis of 3-A-oxy-estra-1,3,5(10),15-tetraen-17-one, wherein A is a protecting group, via said silyl enol ether derivative.
摘要:
Sampler (11) for independent taking of samples from a body cavity, such as cervical samples. Optimum accessibility of the cervix is achieved through the fact that the sampler comprises a rigid plastic tube (14) which is rounded at the front side. As a result, during its introduction by the user, the sampler can accurately be moved to the cervix. Moreover, the sampler is surrounded by the vagina and it is possible to prevent leakage of flushing liquid (15), and consequently it is possible to make do with a relatively small quantity of flushing liquid (15) while at the same time producing a sample with a high concentration of cervical cells. In this way, it is possible to reach the sampling location in a simple and more accurate way which does not damage tissue. As a result of the tube simultaneously being designed as a cylinder for a plunger (12), it is possible, firstly, to flush the desired location with a solution using a cylinder-plunger assembly obtained in this way and, secondly, to take the sample by drawing the plunger (12) back.

One aspect of the invention is concerned with the use of an estrogenic component selected from the group consisting of: substances represented by the following formula
in which formula R 1 , R 2 , R 3 , R 4 independently are a hydrogen atom, a hydroxyl group or an alkoxy group with 1-5 carbon atoms; each of R 5 , R 6 , R 7 is a hydroxyl group; and no more than 3 of R 1 , R 2 , R 3 , R 4 are hydrogen atoms; derivatives of these substances wherein the hydrogen atom of at least one of the hydroxyl groups in said formula has been substituted by an acyl radical of a hydrocarbon carboxylic, sulfonic or sulfamic acid of 1-25 carbon atoms, tetrahydrofuranyl, tetrahydropyranal, or a straight or branched chain glycosidic residue containing 1-20 glycosidic units per residue; and mixtures thereof; in the preparation of a composition for use in a method of hormone replacement therapy, which method comprises non-orally administering to a person in need of such a therapy an effective amount of the estrogenic component without adjunctive progestogen or anti-progestogen treatment, said composition containing no progestogen or anti-progestin. Another aspect of the invention relates to a drug delivery system for enteral or parenteral administration that contains at least 1 µg of the aforementioned estrogenic component and no progestogen or anti-progestin.
摘要:
The present invention relates to a method of treating uterine leiomyomas (fibroids or myomas) in mammal females. More particularly the present invention relates to such a method comprising intravaginal administration of a drug delivery vehicle to a female mammal suffering from uterine leiomyomas, said drug delivery vehicle containing an estrogen activity suppressant selected from the group consisting of aromatase inhibitors, anti-estrogens and mixtures thereof, wherein the method provides the estrogen activity suppressant in a therapeutically effective dosage to inhibit the growth and/or to achieve atrophy of the myomas. The intravaginal administration of estrogen activity suppressant, in comparison to other routes of administration, achieves the desired clinical effect at lower dosage levels and/or without seriously affecting overall estrogen blood serum levels. Another aspect of the invention is concerned with a drug delivery vehicle for intravaginal use, which drug delivery vehicle comprises at least 10 µg of an aromatase inhibitor and/or at least 10 µg of an anti-estrogen and pharmaceutically acceptable excipient.

The present invention is concerned with a pharmaceutical composition for use in a method of hormone replacement. More particularly, the present invention relates to a pharmaceutical composition for use in a method of hormone replacement therapy, which method comprises administering to a person in need of such a therapy an effective amount of an active component selected from the group consisting of:
substances represented by the following formula in which formula R 1 , R 2 , R 3 , R 4 independently are a hydrogen atom, a hydroxyl group or an alkoxy group with 1-5 carbon atoms; R 5 , R 6 , R 7 independently are a hydrogen atom or a hydroxyl group; no more than 3 of R 1 , R 2 , R 3 , R 4 , R 5 , R 6, R 7 are hydrogen atoms and at least 2 of R 5 , R 6, R 7 are a hydroxyl group; precursors capable of liberating a substance according to the aforementioned formula when used in the present method, and mixtures thereof; said composition containing virtually no progestogen or anti-progestin. An example of a known substance which may suitably be used in the method of the invention is 1,3,5 (10)-estatrien-3, 15α,16α,17β-tetrol (estetrol).
摘要:
The present invention relates to a method of improving the fertility of a male mammal. More particularly, the present invention relates to a method of improving the fertility of a male mammal, said method comprising administering to said male mammal estrogen or a combination of estrogen and oxytocin agonist in an amount effective to increase the reproductive quality of the male's semen. Generally accepted parameters that are indicative of the reproductive quality of semen include total sperm count, sperm concentration, ejaculate volume, sperm motility and sperm morphology. Another aspect of the invention relates to an intranasal drug delivery system comprising an intranasal drug delivery device and a drug delivery composition for intranasal delivery, said composition containing at least 3 µg/ml estrogen, at least 3 µg/ml oxytocin agonist and pharmaceutically acceptable excipient.

摘要:
One aspect of the present invention relates to a method of controlled ovarian hyperstimulation in a mammalian female, said method comprising administration to said female of a substance having follicle stimulating hormone activity (FSH substance) in an amount effective to stimulate follicular development and of anti-P in an effective amount to prevent a premature endogenous LH-surge, followed by the administration of a meiosis and luteinisation inducing substance (ML substance) in an amount effective to stimulate resumption of meiosis and luteinisation, and of a progestogen and/or a precursor thereof in an amount effective to prevent or suppress symptoms of progesterone antagonism and/or deficiency, wherein the progestogen and/or the precursor thereof is administered within 24 hours of the first administration of the ML substance. Another aspect of the present invention relates to a pharmaceutical kit for use in a method of controlled ovarian hyperstimulation in mammalian females, said kit comprising a parenteral dosage unit containing a FSH substance, a parenteral or oral dosage unit containing an anti-P and a parenteral or oral dosage unit containing a progestogen and/or a precursor thereof.
