I-Hydroxypropyl Methylcellulose (HPMC) 2910, E5 iyibanga elithile le-HPMC elivumelana namazinga achazwe e-United States Pharmacopeia (USP) 42.
1. I-HPMC 2910: I-HPMC 2910 ibhekisela ebangeni elithile noma uhlobo lwe-HPMC.Izinombolo kugama zisho izakhiwo nezici ezihlukahlukene ze-HPMC, njengokubonakala kwayo, izinga lokushintshwa, kanye nokusatshalaliswa kwesisindo samangqamuzana.Esimeni se-HPMC 2910, i-“2910″ ngokuvamile ibonisa i-viscosity ye-HPMC uma incibilika emanzini endaweni ethile kanye nezinga lokushisa.
2. E5: “E5″ icacisa futhi ibanga le-HPMC ngaphakathi kwesigaba se-HPMC 2910.Lokhu kuqokwa kungase kubhekisele kumapharamitha ekhwalithi athile, njengokusatshalaliswa kosayizi wezinhlayiyana, okuqukethwe umswakama, noma ezinye izibaluli zekhwalithi ezifanele kuhlelo oluhlosiwe.
3. I-USP 42: I-USP 42 ibhekisela ku-United States Pharmacopeia, okuyinhlanganisela ebanzi yolwazi lwezidakamizwa, izindinganiso, nemihlahlandlela eyaziwayo futhi esetshenziswa emhlabeni wonke.I-USP ibeka izindinganiso zobunikazi, ikhwalithi, ubumsulwa, amandla, nokuvumelana kwezinto ezithaka imithi, amafomu omthamo, nezithako zokudla.Ukuthobela izindinganiso ze-USP kuqinisekisa ukuthi imikhiqizo yemithi ihlangabezana nezidingo eziqinile zekhwalithi nokuphepha.
4. Indima kanye Nesicelo: I-HPMC 2910, E5 USP 42 ivame ukusetshenziswa ekwenziweni kwemithi lapho kudingeka khona ukuhambisana nezindinganiso ze-USP.Ibanga layo elithile le-viscosity nemingcele yekhwalithi iyenza ifanelekele izinhlelo zokusebenza ezihlukahlukene, okuhlanganisa:
- Izingubo zethebhulethi
- Ukwakhiwa kokukhishwa okulawulwayo
- Izixazululo ze-Ophthalmic
- Ukwakhiwa kwezihloko
- Ukumiswa kanye emulsions
- I-Binder kanye ne-disintegrant kumaphilisi namaphilisi
5. Ukuthobela Ikhwalithi Nokulawula: Njengebanga le-HPMC elivumelana namazinga e-USP, i-HPMC 2910, E5 ihlangabezana nekhwalithi eqinile nezidingo zokulawula ezibekwe yi-USP.Lokhu kuqinisekisa ukuvumelana, ubumsulwa, nokuphepha ekwakhekeni kwemithi.Abakhiqizi nezinkampani zemithi zingathembela ku-HPMC 2910, E5 USP 42 ekusebenzeni okungaguquguquki nokuhambisana nezindinganiso zokulawula.
Kafushane, i-Hydroxypropyl Methylcellulose (HPMC) 2910, E5 USP 42 iyibanga elithile le-HPMC elihlangabezana nezindinganiso zekhwalithi ezivezwe e-United States Pharmacopeia (USP) 42. Ukuqokwa kwayo kubonisa izinga layo le-viscosity, imingcele yekhwalithi, kanye nokuhambisana nezindinganiso ze-USP. , okwenza ifanelekele ukusetshenziswa kwemithi ehlukahlukene lapho ukuhambisana nezidingo zekhwalithi nokulawula kubalulekile.
