Definitions
- the invention relates to a pharmaceutical composition for contraception and to reduce the risk of congenital malformations, which in a daily dose 0 - 2.0 mg 17 ⁇ -cyanomethyl-17- ⁇ -hydroxyestra-4,9-diene-3on (dienogest) and 0.015 mg 17 ⁇ - Ethinylestradiol (ethinylestradiol) and (6S) -5-methyl-tetrahydrofolate ((6S) -5-MTHF) or
- the invention relates to a kit which contains 21 daily dosage units of the aforementioned active ingredient combination and 7 daily dosage units with (6S) -5-MTHF.
- the invention also relates to a tablet, preferably a film-coated tablet, with the aforementioned active ingredient combination.
- dienogest is proportional, (6S) -5-MTHF not or proportionately or contained as total content and in the film coating, the other part of dienogest, (6S) -5-MTHF not or proportionately or as total content and ethinylestradiol as the total content. 5 State of the art
- Oral contraceptive agents consisting of a progestagen component and an estrogen component first appeared on the market in the early 1960s.
- WO 98/004269 discloses u. a. oral administration of a combination of 250 ⁇ g - 4 mg dienogest and 10 ⁇ g - 20 ⁇ g ethinylestradiol for contraception. To achieve the substantial reduction in the total contraceptive steroid administered per cycle while maintaining good cycle control, the low dose gestagen / estrogen combination is administered for 23 to 25 days of a 28-day menstrual cycle.
- the patent does not disclose any results and data demonstrating that the inventive idea is also successful and what type of release of the steroids is sought.
- Folic acid also pteroyl-mono-glutamic acid, N- (4 - (((2-amino-1,4-dihydro-4-oxo-6-pteridinyl) methyl) amino) benzoyl) glutamic acid (empirical formula: C 19 H 19 N 7 ) O 6 ), called folinic acid, is a heat- and light-sensitive, water-soluble vitamin from the vitamin B complex (vitamin B 9 ). It is known that folates predominantly exist in the diet as pteroyl polyglutamate. These are hydrolyzed after ingestion first in the mucosa cells to pteroyl monoglutamates, then mainly absorbed in the intestine by active transport.
- the predominantly unmethylated folates are converted into methylated folates and bound to the cells mainly as 5-methyltetrahydrofolate (5-MTHF) bound to albumin and ⁇ -macroglobulin, where they are taken up, demethylated and converted into the polyglutamate form.
- 5-MTHF 5-methyltetrahydrofolate
- Demethylation involves the amino acid homocysteine and an enzyme that requires vitamin B 12 as a coenzyme.
- a concentration above 10 ⁇ mol / l is considered critical and from 12 ⁇ mol / l there is need for action.
- enzyme defects can also cause an increase in the homocysteine concentration.
- the connection between increased homocysteine concentrations in the blood and vascular diseases, for example, as a risk factor for cardiovascular diseases has been discussed for some time. It is also discussed whether folic acid / folate can protect against malignant diseases because of its importance for DNA methylation and DNA strand stability.
- congenital malformations such as congenital heart defects, congenital malformations of the urinary tract, acute lymphoblastic leukemia, cleft lip and palate or malformations of the central nervous system, such as neural tube effects (spina bifida or Anencephaly).
- WO 2003/070255 discloses an oral contraceptive, or a kit for oral, hormonal contraception, which contains estrogens and / or gestogens, tetrahydrofolates and mandatory vitamin B 12 or optionally vitamin B 6 .
- WO 2005/1 15349 discloses a dosage form for hormonal contraception with hormone-containing daily units and hormone-free daily units, wherein the hormone-containing daily units contain up to 200 ⁇ folic acid and the hormone-free daily units greater than 200 ⁇ g folic acid.
- Patent EP 0 898 965 claims the use of 5-methyl- (6S) -tetrahydrofolic acid or its pharmaceutically acceptable salts for the prevention of neural tube defects.
- EP 1 044 975 discloses crystalline salts of 5-methyl- (6R 1 S) -, - (6S) -and- (6R) -tetrahydrofolic acid and use as a food supplement ingredient.
- the object of the invention is to disclose a pharmaceutical composition based on dienogest and ethinylestradiol whose steroidal dosage is reduced and which simultaneously reduces the risk of congenital malformations after the onset of pregnancy.
- a pharmaceutical composition for contraception and for reducing the risk of congenital malformations containing in a daily dose of 2.0 mg of ma- cyanomethyl-17-.beta.-hydroxyestra-4,9-dien-3-one (dienogest) and 0.015 mg 17 ⁇ -ethinylestradiol (ethinylestradiol) and (6S) -5-methyltetrahydrofolate ((6S) -5-MTHF) or 1 .5 mg dienogest and 0.015 mg ethinylestradiol and (6S) -5-methyl-tetrahydrofolate ((6S) -5 -MTHF) together with one or more pharmaceutically acceptable excipients / carriers.
- (6S) -5-MTHF or (6S) -5-methyltetrahydrofolic acid may also be referred to as 5-methyl- (6S) -tetrahydrofolate or 5-methyl- (6S) -tetrahydrofolic acid.
- (6S) -5-MTHF the free acid form and pharmaceutically acceptable salts and modifications of (6S) -5-methyltetrahydrofolic acid (N- [4 - [[(2-amino-1, 4,5, 6,7,8-hexahydro-4-oxo-5-methyl- (6S) -pteridinyl) methyl] amino] benzoyl] -L-glutamic acid).
- Pharmaceutically acceptable salts should be pharmacologically as well as pharmaceutically acceptable. Such pharmacologically and pharmaceutically ver Suitable salts may be alkali or alkaline earth metal salts, preferably sodium, potassium, magnesium or calcium salts.
- the calcium salt of (6S) -5-methyltetrahydrofolic acid (metafolin) can be used in various suitable crystalline forms.
