Abstract
Description
technical field
[0001] The present invention relates to novel galenic forms of selective progesterone receptor modulators (SPRMs), more particularly to solid dispersions and pharmaceutical compositions containing said galenical forms. Background technique
[0002] Ulipristal acetate (abbreviated as UPA) corresponds to 17α-acetoxy-11β-[4-(N,N-dimethylamino)phenyl]-19-norpregna-4,9-diene- 3,20-Diketones (IUPAC nomenclature) and have the following chemical formula:
[0003]
[0004] Its synthesis is described inter alia in patent EP0422100 and patent application EP1602662.
[0005] Ulipristal acetate is a synthetic selective progesterone receptor modulator (SPRM). Ulipristal acetate acts as a contraceptive by inhibiting or delaying ovulation by virtue of its action on progesterone receptors. Clinical studies have shown that ulipristal acetate administered in a single dose of 30 mg makes it possible to prevent unwanted pregnancy when administered within 120 hours after unp...
