Abstract
A találmány tárgyát stavudint tartalmazó olyan elnyújtotthatóanyagkibocsátású, extrudált-szferonizált, záróbevonattal ésmódosított hatóanyagkibocsátású bevonattal ellátott szemcsék képezik,amelyek a stavudin hatásos vérszintjét körülbelül 24 órán átbiztosítják. A stavudinnak az extrúziós-szferonizációs eljáráshozszükséges korlátozott mennyiségű víz hatására létrejöhetőhidrolíziséből származó bomlása megakadályozására a szemcsék astavudin jelenlévő tömegére vonatkoztatott körülbelül 0,5 és 3,0tömeg% közötti mennyiségű magnézium-sztearátot, továbbá egyszferonizáló ágenst, előnyösen mikrokristályos cellulózt, egyhígítószert, előnyösen laktózt tartalmaznak. Az estrudált-szferonizáltszemcsék záróbevonata egy filmképző anyagot, előnyösen(hidroxipropil)-metil-cellulózt és egy tapadásgátló anyagot, előnyösentalkumot tartalmaznak. A módosított hatóanyagkibocsátású bevonat egypolimer záróanyagot, előnyösen etil-cellulózt és egy lágyítószert,előnyösen desztillált acetilezett monoglicerideket tartalmaz. Az így,kettős bevonattal ellátott szemcséket keményzselatin kapszulákbatöltik, amelyekbe tölthetnek még a retrovírusos fertőzések kezelésérealkalmas egyéb terápiás szereket tartalmazó hasonló szemcséket is.
