摘要:
Antiandrogenic gestagens in a daily dosage unit, corresponding to no more than two times the dosage required to suppress ovulation, are used in combination with (6S)-5-methyltetrahydrofolate for the production of pharmaceutical preparations for the therapy of endometrioses with simultaneous reduction of therapy side effects, such as the negative impact on bone density/bone metabolism and the risk for osteoporosis, and in the event of pregnancy, the reduction of the risk on congenital malformations, such as neural tube defects, cheilognathopalatoschisis and complications during pregnancy, such as the detachment of the placenta and premature birth. The invention is suitable for long-term use.
摘要:
The present invention relates to solid pharmaceutical compositions, in particular to oral contraceptives, comprising a progestogen, such as drospirenone; an estrogen, such as ethinylestradiol; a tetrahydrofolic acid or a pharmaceutically acceptable salt thereof, such as calcium 5-methyl-(6S)-tetrahydrofolate; and at least one pharmaceutical acceptable excipient or carrier. The compositions of the invention provide good stability of the tetrahydrofolic acid upon storage while still ensuring a fast and reliable release of the estrogen and the progestogen present in the composition.
