Polyethylene Oxide (PEO) Polymer Miisaanka Sare ee Molecular | Matrix-ka Sii-deynta Joogtada ah ee Kiniiniyada Hydrophilic | U hoggaansan USP/EP/ChP

Oxide-keena Daawada ee Polyethylene Oxide (PEO) waa homopolymer aan ionic ahayn oo miisaankiisu sarreeyo, oo biyaha ku milma oo laga heli karo noocyo badan oo kala duwan oo ah viscosity (miisaanka molecular laga bilaabo 100,000 ilaa 7,000,000)Waxay u adeegtaa sidii daawo waxtar u leh qaababka qiyaasta adag ee afka laga qaato. Codsiyada muhiimka ah waxaa ka mid ah: matrix sii-deyn joogto ah (fuuq-celin degdeg ah iyo sameynta jel muddo 10+ saacadood ah oo daawada la sii daayo), xabag-dhejin loogu talagalay habdhiska caloosha iyo mindhicirka, xidhe loogu talagalay granulation iyo cadaadis toos ah, iyo wakiilka sameynta filimada ee filimada khafiifka ah iyo dahaarka qalabka caafimaadkaWaxay la jaanqaadaysaa dawooyinka USP-NF, EP, iyo ChP iyadoo la diiwaangelinayo CDE F20220000511Waxay leedahay fuuq-bax degdeg ah, awood barar sare, sifooyin heerkul-kulul, iyo dabeecad aan ionic ahayn (aan dhadhan lahayn, midab lahayn)
