I-Hydroxypropyl Methylcellulose (HPMC) 2910 E15, USP 42 ibhekisela ebangeni elithile le-HPMC elithobelana namazinga achazwe e-United States Pharmacopeia (USP) 42. Ake sihlole ukuthi lokhu kuqokwa kuhlanganisani:

1. I-HPMC 2910 E15: I-HPMC 2910 E15 icacisa ibanga noma uhlobo lwe-HPMC. Izinombolo nezinhlamvu ekuqokweni zihlinzeka ngolwazi mayelana nezakhiwo nezici ze-HPMC:

• “2910″ ngokuvamile isho ibanga le-viscosity le-HPMC lapho incibilika emanzini endaweni ethile kanye nezinga lokushisa.
• I-“E15″ iphinde icacise ibanga elingaphakathi kwesigaba se-HPMC 2910. Lokhu kuqokwa kungase kubonise amapharamitha ekhwalithi engeziwe, njengokusatshalaliswa kosayizi wezinhlayiyana, okuqukethwe umswakama, noma ezinye izibaluli ezifanele.

2. I-USP 42: I-USP 42 ibhekisela ku-United States Pharmacopeia, ebeka izindinganiso zobunikazi, ikhwalithi, ubumsulwa, amandla, nokuvumelana kwezinto zemithi, amafomu omthamo, nezithako zokudla. Ukuthobela izindinganiso ze-USP kuqinisekisa ukuthi imikhiqizo yemithi ihlangabezana nezidingo eziqinile zekhwalithi nokuphepha.

3. Indima kanye Nesicelo: I-HPMC 2910 E15, i-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

4. Ukuthobela Ikhwalithi Nokulawula: Njengebanga le-HPMC elivumelana namazinga e-USP, i-HPMC 2910 E15, i-USP 42 ihlangabezana nekhwalithi eqinile nezimfuneko zokulawula. Lokhu kuqinisekisa ukuvumelana, ubumsulwa, nokuphepha ekwakhekeni kwemithi. Abakhiqizi nezinkampani zemithi zingathembela ku-HPMC 2910 E15, USP 42 ekusebenzeni okungaguquki nokuthobela izindinganiso zokulawula.

Kafushane, i-Hydroxypropyl Methylcellulose (HPMC) 2910 E15, USP 42 iyibanga elithile le-HPMC elihlangabezana nezindinganiso zekhwalithi ezivezwe e-United States Pharmacopeia (USP) 42. Ukuqokwa kwayo kubonisa izinga layo le-viscosity, amapharamitha ekhwalithi eyengeziwe, nokuhambisana ne-USP. amazinga, okuyenza ifanelekele ukusetshenziswa kwemithi ehlukahlukene lapho ukuhambisana nekhwalithi kanye nezidingo zokulawula kubalulekile.
