Hydroxypropylmethmethcellulose (hpmc) ndi Carboxymethylcellulose (CMC) ndi mitundu iwiri yosiyanasiyana ya ma polima omwe amagwiritsidwa ntchito m'maso amaso, nthawi zambiri amagwiritsa ntchito zizindikiro zowuma. Ngakhale amagawana zofananira, zinthu ziwiri izi zili ndi kusiyana koonekera m'mankhwala, katundu, makina ochita, komanso ntchito zamankhwala.
Hydroxypypyl methylcellulose (HPMC) Diso:
Kapangidwe ka 1.Chemical:
HPMC ndi yopanga zopangidwa ndi cellulose, polymer yachilengedwe imapezeka mu makhoma a cell.
Magulu a hydroxypropyl ndi methyl amayambitsidwa mu ma cellulose, kupereka chuma chapadera cha HPMC.
2. Maonekedwe ndi Rhelogy:
Madontho a HPMC nthawi zambiri amakhala ndi mawonekedwe apamwamba kuposa madontho ena ambiri opangira mafuta.
Makutu owonjezereka amathandizira madonthowo kukhala ozizira kwambiri, popereka mpumulo wautali.
3. Makina a zochita:
HPMC imapanga zoteteza komanso zopaka mafuta pamtunda wa ocrur, ndikuchepetsa kupsinjika ndikuwongolera kukhazikika kwa mafayilo.
Zimathandiza kuthetsa zizindikiro zowuma ndi kupewa misozi.
4.. Ntchito zamankhwala:
Madontho a HPMC nthawi zambiri amagwiritsidwa ntchito pochiza matenda a syndrome.
Amagwiritsidwanso ntchito maopaleshoni a opulmic ndi opaleshoni kuti azikhala ndi thanzi labwino.
5. Zabwino:
Chifukwa cha mafayilo apamwamba, imatha kuwonjezera nthawi yopuma.
Imathetsa bwino zizindikiro zowuma zamaso ndipo zimapereka chitonthozo.
6. Zovuta:
Anthu ena amatha kuwona masomphenya osawoneka bwino atathandizira pakuwonjezereka.
Carboxymethylcellulose (madontho a cmc):
Kapangidwe ka 1.Chemical:
CMC ndi cellulose ina yopangidwa ndi mabatani a Carboxymethyl.
Kuyambitsa kwa carbobobobotthyl gulu kumawonjezera kusungunuka kwamadzi, kupanga masentimita osungunuka madzi.
2. Maonekedwe ndi Rhelogy:
Maso amaso a CMC nthawi zambiri amakhala ndi mamasukidwe otsika poyerekeza ndi madontho a HPMC.
Mafayilo otsika amalola kusungitsa zinthu mosavuta ndikufalikira mwachangu pamwamba pa ocular.
3. Makina a zochita:
CMC imachita ngati mafuta ndi ukazi, kukonza mafayilo okhazikika.
Zimathandiza kuthetsa zizindikiro zowuma ndi kulimbikitsa chinyontho.
4.. Ntchito zamankhwala:
Madontho amaso a CMC amagwiritsidwa ntchito kwambiri kuti athetse zizindikiro zowuma.
Amalimbikitsidwa kwa anthu omwe ali ndi vuto louma lofiirira.
5. Zabwino:
Chifukwa cha mafadwe ake otsika, imafalikira mwachangu ndipo ndizosavuta kugwa.
Moyenera komanso amathetsa matenda owuma.
6. Zovuta:
Kuchepetsa pafupipafupi kungafunikire kuyerekeza ndi mawonekedwe apamwamba a mafayilo.
Kukonzekera kwina kumatha kukhala ndi nthawi yochepa kwambiri yochita zokongoletsera.
Kusanthula Kufananiza:
1. Makutu:
HPMC ili ndi mamasukidwe apamwamba, akupereka mpumulo nthawi yayitali komanso kutetezedwa kwambiri.
CMC ili ndi mamasukidwe otsika, kulola kufalitsa mwachangu komanso kosavuta.
2. Kutenga Nthawi:
HPMC nthawi zambiri imapereka nthawi yayitali chifukwa cha mamasukidwe ake apamwamba.
CMC ingafunikire kuchepa pafupipafupi, makamaka pamaso owuma kwambiri.
3. Chilimbikitso Choleza:
Anthu ena amatha kupeza kuti madontho a HPMC poyamba amayambitsa masomphenya osakhalitsa chifukwa cha mafayilo apamwamba.
Madontho amaso a CMC nthawi zambiri amaloledwa bwino ndipo amapangitsa kuti kusokonezeka koyambirira.
4. Malangizo azachipatala:
HPMC imalimbikitsidwa kwa anthu omwe ali ndi vuto lalikulu lowuma.
CMC imagwiritsidwa ntchito mofatsa kuti ikhale youma komanso yopanda mawonekedwe osakhalitsa.
Hydroxypropylmethmethcellulose (hpmc) ndi Carboxymethylcellulose (madontho a CMC) ndi njira zabwino zothandizira kuchiza matenda a shope. Kusankha pakati pa awiriwo kumatengera zomwe wodwala amakonda, kuopsa kwa diso lowuma, komanso nthawi yomwe mukufuna. Mavinyewa apamwamba a HPMC amateteza mpaka kalekale, pomwe mamasukidwe ocheperako a CMC amapereka mpumulo mwachangu ndipo ungakhale chisankho choyambirira kwa anthu omwe amazindikira masomphenya osakwiya. Oputikitala a Ophthalmogists ndi Maso nthawi zambiri amaganiza izi posankha diso loyenera kwambiri madontho kwa odwala awo, zomwe zidapangidwa kuti zithetse chitonthozo ndikuchiritsa bwino.
