Farmatseutiline hüpromelloosatsetaat-suktsinaat (HPMCAS)

Uquick hüpromelloosatsetaat-suktsinaat (HPMCAS, tuntud ka kui hüdroksüpropüülmetüültselluloosatsetaat-suktsinaat) on tselluloosester, mida kasutatakse tavaliselt ravimitööstuses tahkete ravimvormide enterilise kattematerjalina.

CASi number: 71138-97-1

Farmatseutiline hüpromelloosatsetaat-suktsinaat (HPMCAS)

Hüdroksüpropüülmetüültselluloosatsetaat (HPMCAS) on polümeer, mis on osutunud tõhusaks autoimmuunhaiguste ravis. See on mudelsüsteemiks polümeeri ja valgu vastastikmõjude uurimiseks. Selle polümeeri struktuur sisaldab hüdroksüpropüül-, suktsinoüül- ja atsetaatkomponente. Selle veevaba naatriumisisaldus ja amorfsed omadused võimaldavad tal moodustada vesiniksidemeid teiste polümeeride ja valkudega.

Keemilised omadused

Uquick HPMCAS on valge kuni valkjas pulber või graanulid, millel on nõrk äädikalõhn ja peaaegu olematu maitse. See on saadaval erinevates kvaliteediklassides, mis põhinevad lahustamise pH-l ja osakeste suurusel.

HPMCASi rakendused farmaatsiatööstuses

01

Veesisaldusega pinnakatte dispersioon

Hüdroksüpropüülmetüültselluloosatsetat-suktsinaat (HPMCAS) on suurepärane polümeer, mida kasutatakse tahkete ravimvormide, näiteks tablettide, graanulite ja kapslite enteriliseks katmiseks.

02

Ammoniaagiga täielikult neutraliseeritud enterilise kattekihi koostis

Pindaktiivsete ainete ja plastifikaatorite vältimiseks võib HPMCAS-i täielikult neutraliseerida, et see lahustuks vees, moodustades läbipaistva lahuse. Ammoniaak on osutunud parimaks neutraliseerivaks aineks, kuna seda saab eemaldada kuivatamise käigus.

03

Lahustipõhine pinnakate

Hüdroksüpropüülmetüültselluloosatsektsinaat (HPMCAS) on suurepärane polümeer, mida kasutatakse tahkete ravimvormide (tabletid, tabletid, kapslid) enteriliseks katmiseks.

Lisaks vesipõhistele kattevahenditele saab HPMCASi kasutada ka orgaanilistes koostistes, sest see lahustub mitmesugustes orgaanilistes lahustites.
