Ntchito Zoyambitsa HPMC mu PpmcCatics

Hydroxypylmyl methylcellulose (hpmc) imagwiritsidwa ntchito kwambiri mu ma garmaceustics chifukwa cha malo ake apadera komanso ntchito zosiyanasiyana. Nazi ntchito zofala za hpmc mu malonda ogulitsa mankhwala:

1. Piritsi lokutidwa: hpmc nthawi zambiri imagwiritsidwa ntchito ngati othandizira mafilimu mu piritsi yophimba. Amapanga kanema woonda, wofowoka pamtunda wamapiritsi, ndikuteteza ku chinyezi, kuwala, ndi zachilengedwe. Zovala za HPMC zitha kusokosera kukoma kapena fungo la zosakaniza ndi kuwongolera kumeza.
2. Zosintha zomasulira: hpmc zimagwiritsidwa ntchito pakutulutsa kosinthika kuti muchepetse kutulutsa kwa mankhwala opangira mankhwala (apis) kuchokera mapiritsi ndi makapisozi. Mwa kusiyanasiyana kalasi ya Visctring ndi Kukhazikika kwa HPMC, kukhazikika, kuchedwa, kapena kupanikizika kwa mankhwalawa kungachitike, kulola kuti zigwirizane ndi kuleza mtima komanso kuwongolera wodwala.
3. Mapiritsi a Matrix: HPMC imagwiritsidwa ntchito ngati matrix omwe anali m'mapiritsi omwe amachotsedwa matrix. Imapereka digiri yolumikizira aPis mkati mwa matrix matrix, kulola kumasulidwa kwa mankhwalawa nthawi yayitali. Ma Matrices a HPMC akhoza kupangidwa kuti atulutsidwe mankhwala mu zero-dongosolo, woyamba - kapena kuphatikiza kinetics, kutengera njira zomwe mukufuna.
4. Kukonzekera kwa ophthalmic: HPMC imagwiritsidwa ntchito mu ma ophthalmic mafomu monga wamaso, ma gels, ndi mafuta osintha, mafuta, ndi kangaodive. Zimalimbikitsa nthawi yokhazikika yazomera pamtunda wa ocrur, kukonza mayamwidwe mankhwala, kumatha kudziwa bwino mankhwala, komanso kutonthoza mtima kulephera.
5. Mapangidwe apamwamba: hpmc amagwiritsidwa ntchito kwambiri monga mafuta, ma gels, ndi zotupa ngati phhelsifier, ndi kukhazikika kwa emulsifier, ndi kukhazikika. Imapatsa mafano, kufalitsa, komanso kusasinthika kumapangitsa kugwiritsa ntchito yunifolomu komanso kumasulidwa kwa zosakaniza zakhungu.
6. Zakunja zamanja ndi kuyimitsidwa: HPMC imagwiritsidwa ntchito pakamwa ndikuyimitsidwa ngati mawonekedwe oyimilira, Thicker, ndi kukhazikika. Zimalepheretsa kukhazikika ndikukhazikika kwa tinthu tating'onoting'ono, ndikuwonetsetsa kuti agawidwe a apis motsatizana. HPMC imasinthanso zochulukirapo komanso zophika za pakamwa pakamwa.
7. Wowuma ufa wa inwder (dpis): hpmc amagwiritsidwa ntchito mu mawonekedwe owuma a ufa monga kubalalitsa ndikugulitsa bankha. Imathandizira kupezeka kwa tinthu ta mankhwala osokoneza bongo ndikuwonjezera mphamvu zawo, ndikuonetsetsa kuti apis a APSIS mpaka m'mapapu opuma.
8. Mavalidwe a mabala a mabala: hpmc amaphatikizidwa ndi kuvala kovala bala ngati biohedive ndi chinyezi-chonyowa. Amapanga chipongwe chotetezera pamwamba pa bala, ndikulimbikitsa machiritso, kusinthika kwa minofu, ndi epitheliran. Mavalidwe a HPMC amaperekanso chotchinga ndi kuipitsidwa kwachiporobichi ndikusunga batala yonyowa yoyenera kuchiritsa.

HPMC imachita mbali yovuta kwambiri yopanga mankhwala opangira mankhwala opangira mankhwala opangira mankhwala opangira mankhwala opangira mankhwala osiyanasiyana mafomu osiyanasiyana ndi othandizira. Kuwongolera kwake, chitetezo, ndi kuvomerezedwa kwa owongolera zimapangitsa kuti ikhale yosangalatsa kuti ichulukitse mankhwala osokoneza bongo, kukhazikika, komanso kuvomerezedwa modekha pa malonda ogulitsa mankhwala.
