HPMC nyob rau hauv qhov muag tee

Hydroxypropyl methyl celluloseHPMC yog siv los tsim qhov muag tee, thiab suav nrog cov kauj ruam hauv qab no: ua ntej, hauv cov khoom hauv qab no los ntawm qhov hnyav xaiv cov khoom siv raw, hydroxypropyl methyl cellulose HPMC hauv 3 daim, 40℃rau 70℃nyob rau hauv dej rau kev txhaj tshuaj hauv 300-800, ntxiv cov hydroxypropyl methyl celluloseHPMCmus rau cov dej saum toj no, tshaj thiab tshaj 30 feeb, tom qab tag nrho cov sib npaug sib npaug, txais yuav tsis kub preservation, paub tseeb tias qhov kub cia yog tswj ntawm 0℃-30℃, khaws cia rau ntau tshaj 12 teev, tuaj yeem siv tau; Tom qab ntawd noj 150 qhov chaw los ntawm qhov hnyav ntawm cov dej rau kev txhaj tshuaj kom yaj lwm cov ntaub ntawv nyoos thiab cov khoom siv ntawm qhov muag tee, thiab sib tov sib npaug nrog cov npaj hydroxypropyl methyl cellulose.HPMCtshuaj nyob rau hauv chav tsev kub. Thaum kawg, ntxiv dej rau cov dej sib tov kom txog thaum qhov loj / ntim piv concentration ntawm hydroxypropyl methyl cellulose HPMC yog 0.3%, thiab do tusyees kom tau lub qhov muag tas lawm. Kev tsim kho tuaj yeem tau txais hydroxypropyl methyl celluloseHPMCkev daws teeb meem nrog qhov siab tshaj plaws viscosity thiab clarity, daws qhov teeb meem ntawm nag lossis daus ntawm cov khoom muag qhov muag kawg, thiab txhim kho cov khoom zoo.

Formula ntawm qhov muag tee

Qhov hnyav feem pua ​​​​ntawm txhua yam ntawm qhov muag tee yog: povidone iodine 0.1% ~ 0.5%, lidocaine 0.5% ~ 1%, hydroxypropyl methyl cellulose HPMC 0.5% ~ 1.5%, flumeilon 0.05% ~ 0.15%, sodium hyaluronate 0.01% 0.05%. %. Cov txheej txheem kev npaj tau piav qhia, nrog cov dej distilled raws li thawj povidone iodine, lidocaine, fluorine zaj, hydroxypropyl methyl cellulose, sodium hyaluronate ua los ntawm dissolving povidone iodine tov, lidocaine tov, fluorine zaj tov, hydroxypropyl methyl cellulose tov, sodium hyaluronate tov, ces iodine hyaluron. tshuaj, lidocaine tov, fluorine zaj tov thiab / los yog thiab hydroxypropyl methyl cellulose tov / los yog sodium hyaluronate tov yog tov los tsim ib tug tov tov tom qab kev npaj ntawm qhov muag tee. Lub invention zoo heev broadens lub dav spectrum ntawm qhov muag tee thiab txo cov irritation rau lub cornea.
