I-Excipient Yezemithi
I-Hydroxypropyl methylcellulose (HPMC) imhlophe noma i-milky white, ayinaphunga, ayinambitheki, impushana ene-fibrous noma i-granule, ukuncipha kwesisindo lapho isomiswa akudluli u-10%, incibilika emanzini abandayo kodwa hhayi emanzini ashisayo, kancane kancane emanzini ashisayo Ukuvuvuka, ukupeptiza, nokwenza i- isixazululo se-viscous colloidal, esiba yisixazululo lapho sipholile, futhi sibe ijeli lapho sishiswa. I-HPMC ayincibiliki ku-ethanol, i-chloroform ne-ether. Incibilika ku-solvent exubile ye-methanol ne-methyl chloride. Iphinde inyibilike ku-solvent exubile ye-acetone, i-methyl chloride ne-isopropanol nezinye izinyibilikisi eziphilayo. Isixazululo saso esinamanzi singabekezelela usawoti (isixazululo saso se-colloidal asibhujiswa usawoti), futhi i-pH ye-1% yesisombululo samanzi ngu-6-8. Ifomula ye-molecular ye-HPMC yi-C8H15O8-( C10H18O6) -C815O, kanti isisindo se-molecular mass cishe yi-86,000.
I-HPMC inokuncibilika okuhle kakhulu kwamanzi emanzini abandayo. Ingancibilika ibe yisixazululo esisobala ngokunyakazisa kancane emanzini abandayo. Ngokuphambene nalokho, empeleni ayincibiliki emanzini ashisayo angaphezu kuka-60 ℃ futhi ingavuvukala kuphela. I-non-ionic cellulose ether. Isixazululo saso asinakho ukushaja kwe-ionic, asihlanganisi nosawoti wensimbi noma izinhlanganisela eziphilayo ze-ionic, futhi asisabelani nezinye izinto zokusetshenziswa phakathi nenqubo yokulungiselela; inezindawo eziqinile zokulwa ne-allergies, futhi ngokukhuphuka kwezinga lokushintshwa kwesakhiwo samangqamuzana, Iphikisana kakhulu ne-allergies futhi izinzile; futhi i-inert metabolism. Njengengxenye yezemithi, ayigaywa imetabolism noma imuncwe. Ngakho-ke, ayinikezi ama-calories emithini nasekudleni. Inekhalori ephansi, ayinawo usawoti, futhi ayinawo usawoti ezigulini ezinesifo sikashukela. Izidakamizwa ezingezwani nokudla zinokusebenza okuyingqayizivele; izinzile uma kuqhathaniswa nama-acids nama-alkali, kodwa uma inani le-PH lidlula u-2~11 futhi lithintwa amazinga okushisa aphakeme noma linesikhathi eside sokulondoloza, i-viscosity yayo izokwehla; isixazululo saso esinamanzi singanikeza umsebenzi we-Surface, okubonisa ukungezwani kwendawo okumaphakathi kanye nokungezwani kobuso; ine-emulsification ephumelelayo ohlelweni lwezigaba ezimbili, ingasetshenziswa njenge-stabilizer ephumelelayo kanye ne-colloid evikelayo; isixazululo saso esinamanzi sinezinto ezinhle kakhulu zokwenza ifilimu, ithebhulethi kanye nephilisi Into enhle yokugqoka. Ukufakwa kwefilimu okwenziwe yikho kunezinzuzo zokungabi mbala nokuqina. Ukwengeza i-glycerin nakho kungathuthukisa ipulasitiki yayo.
Imikhiqizo ye-QualiCell HPMC ingathuthuka ngalezi zakhiwo ezilandelayo ku-Pharmaceutical Excipient:
·Uma inyibilika emanzini futhi ishintshashintsha ngesincibilikisi, i-HPMC yenza ifilimu ebonisa ngale enamandla aqine kakhulu.
·Ithuthukisa amandla okubopha .
·I-Hydrophilic matrix esetshenziswa kanye nama-hydrates e-HPMC ukuze kwakheke isendlalelo sejeli, elawula iphethini yokukhululwa kwezidakamizwa.
