I-Hydroxypropyl methylcellulose (HPMC) isetshenziswa kakhulu ekunambeni amaphilisi. Njengomsizi ojwayelekile wemithi, inemisebenzi eminingi kanye nezinzuzo.
Izinto zokwakha ifilimu: I-HPMC ingenye yezinto ezivame ukusetshenziswa ekwakhiweni kwefilimu ekuhlanganiseni ifilimu. Inezici ezinhle zokwenza ifilimu, amandla efilimu afanelekile, isendlalelo sokumboza esisobala, futhi akulula ukuqhekeka. Iyazinza uma iqhathaniswa nokukhanya, ukushisa kanye nokuswakama okuthile, futhi iyancibilika kuzincibilikisi zemvelo nasemanzini. Inomphumela omncane omubi ekuhlakazeni nasekuhlakazweni kwamaphilisi. Ngakho-ke, isetshenziswa kabanzi esiswini esincibilikayo enamathela impahla enomphumela omuhle wefilimu enamathela.
Vikela i-API: Ukugcoba kwe-HPMC kungavikela izithako ezisebenzayo zemithi (API) ezicini zemvelo ezifana nokukhanya, i-oxidation kanye nomswakama, ukuqinisekisa ukuthi umuthi ungaqhubeka nokudlala indima yawo ohlosiwe ngisho nangemva kokugcinwa isikhathi eside.
Lawula ukukhishwa kwezidakamizwa: Ngokugcotshwa kwefilimu, abakhiqizi bezidakamizwa bangalawula indawo yokukhishwa, isilinganiso nesikhathi se-API. Lokhu kubaluleke kakhulu kwezinye izidakamizwa ezidinga ukukhishwa ngokubambezeleka, noma ezidakamizweni okufanele zikhiphe inani elingashintshi le-API phakathi nenkathi ethile yesikhathi.
Thuthukisa ukuthobela kwesiguli: Amaphilisi afakwe ifilimu kulula ukuwathatha, angathuthukisa ukuthobela kwesiguli.
Thuthukisa ukubukeka kwethebhulethi: Ukumbozwa kwefilimu kunganikeza indawo ebushelelezi nemibala egqamile, kuthuthukise ukuqashelwa komkhiqizo nolwazi lwemithi yesiguli.
Njengesibophezelo kanye ne-disintegrant: I-HPMC ingasetshenziswa futhi njengesibophezelo. Isixazululo sayo se-HPMC se-viscosity ephansi singanciphisa ngempumelelo i-engeli yokuxhumana yomuthi, evumela ukumanziswa komuthi. I-coefficient yokunweba ngemva kokumunca amanzi ingafinyelela izikhathi ezingamakhulu, okungathuthukisa kakhulu izinga lokukhululwa komuthi ukuhlakazeka nokuhlakazeka.
Thuthukisa ukuzinza kwethebhulethi: I-HPMC ine-hygroscopicity ephansi, engasetshenziswa njengenzuzo ngoba inganciphisa izinkinga zokuzinza ezibangelwa ukumuncwa komswakama ngesikhathi sokugcina amaphilisi.
Njengempahla yohlaka lwamathambo okukhululwa okuqhubekayo: Emalungiselelweni okukhishwa okuqhubekayo, i-HPMC ingasetshenziswa njengezinto ze-hydrophilic skeleton. Ngokulungisa i-viscosity kanye nemithamo ye-HPMC, izinga lokukhululwa lomuthi lingalawulwa ukuze kuzuzwe umphumela wokukhishwa okuqhubekayo komuthi.
Thuthukisa ukunyibilika: Isixazululo se-ethanol se-HPMC noma isixazululo esinamanzi sisetshenziswa njenge-ejenti yokumanzisa imbudumbudu, esebenza ngempumelelo ekuthuthukiseni ukunyibilika kwamaphilisi.
Thuthukisa ikhwalithi yokumboza: Njengento yokwenza ifilimu, i-HPMC inenzuzo enkulu kunezinye izinto zokwakha ifilimu ngoba iyancibilika emanzini, ayidingi izinyibilikisi zemvelo, futhi iphephile futhi kulula ukuyisebenzisa. I-HPMC futhi inezinhlobonhlobo zokucaciswa kwe-viscosity. Uma isetshenziswe kahle, ikhwalithi nokubukeka kwamaphilisi aboshwe kungcono kunezinye izinto.
I-HPMC isetshenziswa kakhulu ekwengezeni ithebhulethi, engakwazi nje ukuthuthukisa ikhwalithi nokubukeka kwamaphilisi, kodwa futhi ivikele ngempumelelo izithako zezidakamizwa, ilawule ukukhishwa kwezidakamizwa, futhi ithuthukise ukuthobela isiguli.
