Definitions
- the invention relates to a process for the preparation of a monophasic pharmaceutical preparation for limiting / reducing the risk of deep vein thrombosis in unit with an oral contraception.
- a contraceptive combination with 2.0 mg of 17 ⁇ -cyanomethyl-17- ⁇ -hydroxyestra-4,9-diene-3on (dienogest) and 0.030 mg of 17 ⁇ -ethinylestradiol (ethinylestradiol) or 2.0 mg of dienogest and 0.020 mg of ethinylestradiol to nx21 daily
- Venous thromboembolism is rare in young women. For those under 45 who do not use oral contraceptives, 5 to 10 events per 100,000 woman-years are expected. Intake of oral contraceptives increases the risk (Birkhauser, M et al: Recommendations on hor- ovonal knee function - 34th workshop of the "Zurich Discussion Group", April 2005, Gynecological Obstlove, Rundsch 2006; 46: 58-63) It has also been found that the risk depends on the dose of ethinyl estradiol, and various observational studies have indicated that oral contraceptives containing so-called third generation progestogens such as desogestrel and gestodene may be associated with a higher risk than oral contraceptives with progestogens of the so-called second generation , such as Le-nororgestrel (Weiss, G: Risk of Venous Thromboembolism with Third Generation Oral Con- stceptives: A review, Am J Obstet Gyne
- progestogens are not a homogeneous class of hormones but differ in their hormonal activity pattern.
- progestogens with androgenic properties such as levonorgestrel, could hinder the effect of ethinylestradiol on some hemostasis factors, while progestogens lacking orrogenic activity, e.g. As chlormadinone acetate or cyproterone acetate, have no effect.
- progestradiol and the various progestogens can directly affect endothelial and smooth muscle cell function.
- progestogens such as medroxyprogesterone acetate, gestodene or 3-keto-desogestrel, which can up-regulate the thrombin receptor and tissue factor and thus the procoagulant activity in the vessel wall. This is probably due to their own glucocorticoid effect.
- the conventional oral contraceptive regimen which typically consists of 21 days of use of an estrogen / progestogen combination followed by a hormone-free interval of 7 days, was introduced about 45 years ago and is still the standard of hormonal contraception. However, there is no medical reason for the regular withdrawal bleeding, which is associated with the rapid decline in serum concentrations of contraceptive steroids during the pill-free week. This regimen was chosen to mimic the natural cycle and to promote the general acceptance of this new contraceptive method.
- a process for the preparation of a single-phase pharmaceutical preparation for limiting / reducing the risk of deep vein thrombosis in unit with an oral contraception which comprises a contraceptive combination with 2.0 mg 17 ⁇ -cyanomethyl-17- ⁇ - hydroxyestra-4,9-dien-3-one (dienogest) and 0.030 mg 17 ⁇ -ethinylestradiol (ethinylestradiol) or 2.0 mg dienogest and 0.020 mg ethinylestradiol at nx21 daily dose units with following nx21 maximally 7 daily non-occupational or placebo containing dosage units and where n equals 2 , 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, and 17.
- hemostasis factors such as factor VI I and factor VI II and the reduction of antithrombin and protein S, observed during oral contraceptive use in women receiving DVT during conventional oral contraceptive use occurred, is more pronounced.
- the results of the present study clearly show that there is no significant difference between conventional and long-cycle haemostatic parameters during treatment with ethinylestradiol / dienogest at any time. These results indicate that the intermediate increase in procoagulant and fibrinolytic activity observed after 3 months of use did not change significantly during further treatment. In addition, the results show that a steady-state of the estrogen-dependent changes is achieved after only 3 months.
- Valette is a conventional dragee for oral contraception containing
- the example describes a film tablet with matrix core.
- the core of the film-coated tablet contains 1 mg dienogest in a hydrophilic erosion matrix with the basic component metolose.
- the matrix releases the active ingredient dienogest with a sustained release.
- the core was coated with a fast-dissolving film containing 1.0 mg dienogest and 0.02 mg ethinylestradiol.
- the film-coated tablet was coated with another rapidly soluble color layer containing iron oxide pigments.
- Ethinylestradiol can also be an ethinylestradiol-beta-cyclodextrin complex. If the ethinylestradiol-beta-cyclodextrin complex (1: 2) is used, a maximum of about ten times the amount should be used.
