Hydroxypropylmethylcellulose (HPMC) na carboxymethylcellulose (CMC) ni ubwoko bubiri bwa polymers bukoreshwa muburyo bwo guta amaso, akenshi bukoreshwa mugukuraho ibimenyetso byamaso yumye. Nubwo basangiye bimwe, ibyo bice byombi bifite itandukaniro rigaragara muburyo bwimiti, imiterere, uburyo bwibikorwa, hamwe nubuvuzi bukoreshwa.
Hydroxypropyl methylcellulose (HPMC) ibitonyanga by'amaso:
1.Imiterere yimiti:
HPMC ni intungamubiri ikomoka kuri selile, polymer karemano iboneka murukuta rw'utugingo ngengabuzima.
Hydroxypropyl na methyl matsinda byinjizwa mumiterere ya selile, biha HPMC ibintu byihariye.
2. Viscosity and rheology:
HPMC ibitonyanga by'amaso muri rusange bifite ubukonje burenze ubwinshi bwibitonyanga byamaso.
Ubwiyongere bwiyongera bufasha ibitonyanga kuguma hejuru ya ocular hejuru, bitanga ubutabazi burambye.
3. Uburyo bwibikorwa:
HPMC ikora urwego rwo gukingira no gusiga amavuta hejuru ya ocular, kugabanya ubukana no kunoza amarira ya marira.
Ifasha kugabanya ibimenyetso byamaso yumye birinda guhumeka cyane amarira.
4. Gusaba ivuriro:
HPMC ibitonyanga byamaso bikoreshwa mugukiza syndrome yumaso.
Zikoreshwa kandi mububaga bw'amaso no kubagwa kugirango ibungabunge amazi ya corneal.
5. Ibyiza:
Bitewe n'ubukonje buhanitse, irashobora kongera igihe cyo gutura hejuru ya ocular.
Kuraho neza ibimenyetso byamaso yumye kandi bitanga ihumure.
6. Ibibi:
Abantu bamwe barashobora kubona ibyerekezo bidahita nyuma yo gushiramo kubera kwiyongera kwijimye.
Carboxymethylcellulose (CMC) ibitonyanga by'amaso:
1.Imiterere yimiti:
CMC nubundi selile ikomoka kuri selile ya carboxymethyl.
Itangizwa ryitsinda rya carboxymethyl ryongera imbaraga zo gukama amazi, bigatuma CMC ikora polymer-amazi.
2. Viscosity and rheology:
Amaso ya CMC muri rusange afite ubukonje buke ugereranije n'amaso ya HPMC.
Ubukonje bwo hasi butuma byoroha gushiramo no gukwirakwira vuba hejuru ya ocular.
3. Uburyo bwibikorwa:
CMC ikora nk'amavuta kandi yoroheje, igateza imbere amarira ya firime.
Ifasha kugabanya ibimenyetso byamaso yumye biteza imbere kugumana ubushuhe hejuru yijisho.
4. Gusaba ivuriro:
Ibitonyanga by'amaso bya CMC bikoreshwa cyane mu kugabanya ibimenyetso by'amaso yumye.
Mubisanzwe birasabwa kubantu bafite syndrome yumaso yoroheje kandi yoroheje.
5. Ibyiza:
Bitewe n'ubukonje buke, ikwirakwira vuba kandi byoroshye gutonyanga.
Muburyo bwiza kandi bwihuse kugabanya ibimenyetso byamaso yumye.
6. Ibibi:
Kurenza urugero birashobora gukenerwa ugereranije nibisobanuro bihanitse.
Imyiteguro imwe irashobora kugira igihe gito cyibikorwa hejuru ya ocular.
Isesengura rigereranya:
1. Viscosity:
HPMC ifite ububobere buke, butanga ubutabazi burambye kandi burinda umutekano burambye.
CMC ifite ububobere buke, butuma ikwirakwira vuba kandi byoroshye.
2. Igihe cyibikorwa:
HPMC muri rusange itanga igihe kirekire cyibikorwa kubera ubwinshi bwayo.
CMC irashobora gusaba inshuro nyinshi kunywa, cyane cyane mugihe amaso yumye cyane.
3. Guhumuriza abarwayi:
Abantu bamwe bashobora gusanga ibitonyanga byamaso ya HPMC byambere bitera guhubuka kwigihe gito kubera iyerekwa ryinshi.
Ibitonyanga by'amaso bya CMC muri rusange byihanganirwa kandi bigatera kutitonda kwambere.
4. Ibyifuzo byubuvuzi:
HPMC muri rusange irasabwa kubantu bafite syndrome yumaso yoroheje kandi ikabije.
Ubusanzwe CMC ikoreshwa mumaso yoroheje cyangwa yoroheje yumye kandi kubantu bakunda amata make.
Hydroxypropylmethylcellulose (HPMC) hamwe na carboxymethylcellulose (CMC) ibitonyanga byamaso byombi ni uburyo bwiza bwo kuvura ibimenyetso byamaso yumye. Guhitamo byombi biterwa numurwayi ku giti cye, ubukana bwijisho ryumye, nigihe cyigihe cyo gukora. Ububasha bukabije bwa HPMC butanga uburinzi burambye, mugihe ubukonje buke bwa CMC butanga ubutabazi bwihuse kandi birashobora kuba amahitamo yambere kubantu bumva neza kutabona neza. Abaganga b'amaso n'abakora ubuvuzi bw'amaso bakunze gutekereza kuri izi ngingo muguhitamo ibitonyanga bikwiriye amavuta kubarwayi babo, bigamije koroshya ihumure no kugabanya neza ibimenyetso byamaso yumye.
