HydroxypropenCellulose (HPMC) thiab Carboxymethylcelleculose (CMC) yog ob hom kev poob hauv qhov muag poob tsim, feem ntau siv los ua kom cov tsos mob qhuav. Txawm hais tias lawv qhia qee yam sib xws, ob lub tebchaw muaj qhov sib txawv ntawm lawv cov qauv tshuaj, cov khoom, cov ntawv thov kev kho mob.
HydroxyPropyyl methylcellulose (HPMC) qhov muag poob qis:
1. Dememical qauv:
HPMC yog hluavtaws derivative ntawm cellulose, lub ntuj polymer pom hauv tsob ntoo cell phab ntsa.
Hydroxypropyl thiab methyl pawg tau qhia rau hauv cov qauv cellulose, muab HPMC cov khoom muaj txiaj ntsig.
2. Viscosity thiab rheology:
HPMC qhov muag poob feem ntau muaj viscosity ntau dua li ntau lwm lub raj raj lubricating qhov muag poob.
Cov viscosity ntau ntxiv pab kom poob qis nyob rau ntawm ormular sab ntev, muab lub sijhawm ntev.
3. Mechanism ntawm Kev Ua:
HPMC ua cov txheej txheem tiv thaiv thiab lubricating thiab lubricating txheej nyob rau hauv ovular nto, txo kev sib txhuam thiab txhim kho kua muag stability stability.
Nws pab txhawb cov tsos mob qhuav los ntawm kev tiv thaiv ntau dhau ntawm evaporation ntawm kua muag.
4. Cov Ntawv Thov Kev Kho Mob:
HPMC qhov muag poob qis yog siv tau los kho qhov muag qhuav.
Lawv kuj tseem siv hauv Ophthalmic kev phais thiab phais kom tswj tau cornation hydration.
5. Cov txiaj ntsig:
Vim yog cov viscosity siab dua, nws tuaj yeem txuas lub sijhawm nyob ntawm qhov chaw ntawm Ocular.
Cov tsos mob ua tau qhov muag qhuav thiab muab kev nplij siab.
6. Qhov tsis zoo:
Qee tus neeg yuav muaj kev tsaus muag pom kev sai tom qab tau nyiaj ntxiv vim muaj viscosity ntau ntxiv.
Carboxymetylcelleculose (cmc) qhov muag poob:
1. Dememical qauv:
CMC yog lwm cov cellulose derivative hloov nrog pawg carboxymethyl.
Cov lus qhia ntawm Carboxymethyl pab pawg txhim kho cov dej solubility, ua CMC lub solub-soluble polymer.
2. Viscosity thiab rheology:
CMC qhov muag poob feem ntau muaj qhov qis viscosity piv rau HPMC qhov muag poob.
Qhov qis viscosity tso cai rau cov nyiaj tau yooj yim thiab nrawm dua li ntawm qhov chaw ntawm Ocular.
3. Mechanism ntawm Kev Ua:
CMC ua raws li cov roj nplua nyeem thiab nyiam, txhim kho kua muag zaj duab xis nyob ruaj khov.
Nws pab txhawb kev cov tsos mob qhuav los ntawm kev txhawb cov dej noo kev khaws cia ntawm lub qhov muag nto.
4. Cov Ntawv Thov Kev Kho Mob:
CMC qhov muag poob tau dav siv los daws cov tsos mob qhuav.
Lawv feem ntau pom zoo rau cov neeg uas muaj mob me rau cua daj cua dub.
5. Cov txiaj ntsig:
Vim nws cov viscosity qis, nws kis tau sai thiab yog qhov yooj yim txia.
Ua tau zoo thiab thim rov qab sai sai.
6. Qhov tsis zoo:
Yuav tsum tau siv ntau zaus yuav tsum tau muab piv rau cov qauv visciority siab dua.
Qee qhov kev npaj yuav muaj ncua sijhawm luv ntawm kev nqis tes ua ntawm qhov chaw ntawm Ocular.
Kev Tshaj Tawm:
1. Viscosity:
HPMC muaj viscosity ntau dua, muab kev tiv thaiv ntev dua thiab muaj kev tiv thaiv ntau dua.
CMC muaj cov viscosity qis dua, pub rau cov kis las nrawm dua thiab yooj yim.
2. Kev txiav txim siab Duration:
HPMC feem ntau muab sijhawm ntev ntawm kev txiav txim siab vim nws cov viscosity ntau dua.
CMC yuav xav tau kev tshuaj ntau ntau, tshwj xeeb yog nyob rau lub qhov muag qhuav heev.
3. Tus neeg mob nplij:
Qee tus neeg yuav pom tias HPMC qhov muag poob rau thaum pib blurring ntawm lub zeem muag vim lawv ntau hom viscosity.
CMC qhov muag poob tau feem ntau zoo zam rau thiab ua rau muaj tsawg dua kev ua plooj plooj.
4. Cov lus pom zoo saib xyuas:
HPMC feem ntau pom zoo rau cov neeg uas muaj mob hnyav rau qhov muag tsis qhuav.
CMC feem ntau yog siv rau cov me me mus rau lub qhov muag qhuav thiab rau cov neeg uas nyiam cov mis uas tsis muaj peev xwm ua kom muaj kuab.
Hydroxypropylencellulose (HPMC) thiab carboxymethylcelleculose (cmc) qhov muag poob yog ob qho txiaj ntsig zoo rau kev kho cov tsos mob qhuav. Qhov kev xaiv ntawm ob qho ntawm tus neeg mob tus nyiam nyiam, qhov mob hnyav ntawm lub qhov muag qhuav, thiab lub sijhawm xav tau ntawm kev nqis tes ua. HPMC cov viscosity siab dua muab kev tiv thaiv ntev dua, thaum cmc qhov qis viscosity muab kev pab sai thiab yuav yog thawj qhov kev xaiv rau cov neeg muaj lub zeem muag. Ophthalmologist thiab cov neeg saib xyuas qhov muag feem ntau xav txog cov kev tsim nyog ntawm cov tee rau lawv cov neeg mob, tsim tau kom muaj cov tsos mob qhuav.
