I-Hydroxypropyl Methylcellulose (HPMC)iyi-ether ye-cellulose engeyona i-ionic enezakhiwo ezinhle zokwakha ifilimu, ukunamathela, ukuqina kanye nokulawulwa kokukhululwa, futhi isetshenziswa kabanzi embonini yezemithi. Njenge-excipient yezemithi, i-AnxinCel®HPMC ingasetshenziswa kumathebulethi, ama-capsule, amalungiselelo okukhululwa okuqhubekayo, amalungiselelo amehlo kanye nezinhlelo zokulethwa kwemithi yangaphandle.
1. Izakhiwo ze-HPMC ze-physicochemical
I-HPMC iyinto eyenziwe nge-polymer etholakala nge-methylating kanye ne-hydroxypropylating natural cellulose, enokuncibilika kwamanzi okuhle kakhulu kanye nokuhambisana kwezinto eziphilayo. Ukuncibilika kwayo akuthinteki kakhulu izinga lokushisa kanye nenani le-pH, futhi ingavuvukala emanzini ukuze yakhe isixazululo esiqinile, esiza ukukhishwa kwemithi okulawulwayo. Ngokusho kwe-viscosity, i-HPMC ingahlukaniswa ngezigaba ezintathu: i-viscosity ephansi (5-100 mPa·s), i-viscosity ephakathi (100-4000 mPa·s) kanye ne-viscosity ephezulu (4000-100000 mPa·s), ezifanele izidingo ezahlukene zokulungiselela.
2. Ukusetshenziswa kwe-HPMC emithini yokwelapha
2.1 Ukusetshenziswa kumathebulethi
I-HPMC ingasetshenziswa njenge-binder, i-disintegrant, i-coating material kanye ne-release controlled-release material kumaphilisi.
Isibophezeli:I-HPMC ingasetshenziswa njenge-binder ekubunjweni okumanzi noma ekubunjweni okomile ukuze kuthuthukiswe amandla ezinhlayiya, ukuqina kwethebhulethi kanye nokuzinza kwemithi ngomshini.
Ukungavumelani:I-HPMC evimbekile kancane ingasetshenziswa njengesihlanzi ukukhuthaza ukubola kwamaphilisi nokwandisa izinga lokubola kwemithi ngemva kokuvuvukala ngenxa yokumuncwa kwamanzi.
Izinto zokumboza:I-HPMC ingenye yezinto eziyinhloko zokugqoka amaphilisi, ezingathuthukisa ukubukeka kwemithi, zifihle ukunambitheka okubi kwemithi, futhi zingasetshenziswa ekugqokeni kwe-enteric noma ekugqokeni ifilimu ngama-plasticizers.
Izinto ezikhishwa ngokulawulwa: I-HPMC enokuqina okuphezulu ingasetshenziswa njengento ehlanganisiwe ukuze ilibazise ukukhishwa kwemithi futhi ifinyelele ukukhishwa okuqhubekayo noma okulawulwayo. Isibonelo, i-HPMC K4M, i-HPMC K15M kanye ne-HPMC K100M zivame ukusetshenziswa ukulungiselela amaphilisi akhishwa ngokulawulwayo.
2.2 Ukusetshenziswa kumalungiselelo e-capsule
I-HPMC ingasetshenziswa ukukhiqiza ama-capsule angenalutho athathwe ezitshalweni ukuze athathe indawo yama-capsule e-gelatin, afanele abantu abadla imifino kanye nabantu abane-allergy kuma-capsule athathwe ezilwaneni. Ngaphezu kwalokho, i-HPMC ingasetshenziswa ukugcwalisa ama-capsule aketshezi noma aqinile ukuze kuthuthukiswe ukuzinza kanye nezici zokukhulula izidakamizwa.
2.3 Ukusetshenziswa kumalungiselelo amehlo
I-HPMC, njengengxenye eyinhloko yezinyembezi zokwenziwa, ingandisa ukujiya kwamaconsi amehlo, yandise isikhathi sokuhlala kwemithi ebusweni bamehlo, futhi ithuthukise ukutholakala kwayo. Ngaphezu kwalokho, i-HPMC ingasetshenziswa futhi ukulungisa amajeli amehlo, amafilimu amehlo, njll., ukuthuthukisa umphumela wokukhululwa okuqhubekayo kwemithi yamehlo.
2.4 Ukusetshenziswa ekulungiseleleni ukulethwa kwemithi nge-topical
I-AnxinCel®HPMC inezakhiwo ezinhle zokwakha ifilimu kanye nokuhambisana kwezinto eziphilayo, futhi ingasetshenziswa ukulungiselela ama-patches e-transdermal, ama-gel kanye nama-cream. Isibonelo, ezinhlelweni zokulethwa kwemithi ye-transdermal, i-HPMC ingasetshenziswa njengento ye-matrix ukwandisa izinga lokungena kwemithi nokwandisa isikhathi sokusebenza.
2.5 Ukusetshenziswa koketshezi lomlomo kanye nokumiswa
I-HPMC ingasetshenziswa njengesithambisi kanye nesiqinisi ukuthuthukisa izakhiwo ze-rheological zoketshezi oluphuzwayo kanye nokumiswa, ukuvimbela izinhlayiya eziqinile ukuthi zingahlali, kanye nokuthuthukisa ukufana kanye nokuzinza kwemithi.
2.6 Ukusetshenziswa kumalungiselelo okuphefumula
I-HPMC ingasetshenziswa njengesithwali se-dry powder inhalers (DPIs) ukuthuthukisa ukugeleza nokusabalala kwemithi, ukwandisa izinga lokufakwa kwemithi emaphashini, ngaleyo ndlela kuthuthukiswe umphumela wokwelapha.
3. Izinzuzo ze-HPMC kumalungiselelo okukhululwa okuqhubekayo
I-HPMC inezici ezilandelayo njengesithako esikhishwa njalo:
Ukuncibilika kwamanzi okuhle:Ingavuvukala ngokushesha emanzini ukuze yakhe isithiyo sejeli futhi ilawule izinga lokukhishwa kwemithi.
Ukuhambisana okuhle kwezinto eziphilayo:ayinabo ubuthi futhi ayicasuli, ayimuncwa ngumzimba womuntu, futhi inendlela ecacile yokusebenza komzimba.
Ukuzivumelanisa nezimo okuqinile:Ifanele izinhlobo ezahlukene zemithi, okuhlanganisa imithi encibilika emanzini kanye nemithi engabangeli ukungezwani kwamanzi.
Inqubo elula:Ifanelekela izinqubo ezahlukahlukene zokulungiselela njengokufaka amaphilisi ngqo kanye nokufaka i-granulation emanzini.
Njengomphelelisi obalulekile wemithi,I-HPMCisetshenziswa kabanzi emikhakheni eminingi efana namaphilisi, ama-capsule, amalungiselelo amehlo, amalungiselelo angaphandle, njll., ikakhulukazi kumalungiselelo okukhululwa okuqhubekayo. Esikhathini esizayo, ngentuthuko eqhubekayo yobuchwepheshe bokulungiselela imithi, ububanzi bokusetshenziswa kwe-AnxinCel®HPMC buzokwandiswa kakhulu, kuhlinzekwe imboni yemithi ngezinketho ezisebenza kahle neziphephile zokwengeza.
