HydroxyPropyl Methyl Cellulose mumatonyanga y'amaso

Hydroxypropyl methylcellulose (HPMC) ikoreshwa cyane mubitonyanga byamaso kugirango ibashe gusiga hamwe na viscoelastic. Dore inzira zimwe HPMC ikoreshwa mubitonyanga byamaso:

Gusiga: HPMC ikora nk'amavuta mu bitonyanga by'amaso, itanga ubushuhe n'amavuta hejuru yijisho. Ibi bifasha kugabanya ibibazo biterwa nijisho ryumye mugabanya ubushyamirane buri hagati yijisho na cornea.

Kongera imbaraga za Viscosity: HPMC yongerera ubwiza bwibitonyanga byamaso, bifasha kongera igihe cyo guhura kwabo hejuru ya ocular. Iki gihe kinini cyo guhura cyongera imbaraga zijisho ryijisho mugutobora no guhumuriza amaso.

Kugumana: Imiterere ya HPMC ifasha ibitonyanga by'amaso kwizirika hejuru ya ocular, bikongerera igihe cyo kugumana ijisho. Ibi bituma habaho gukwirakwiza neza ibintu bikora kandi bikanatanga amazi menshi hamwe no gusiga amavuta.

Kurinda: HPMC ikora firime ikingira hejuru ya ocular, ikayirinda ibidukikije byangiza ibidukikije. Iyi barrière ikingira ifasha kugabanya uburakari no gutwika, itanga ihumure kubantu bafite amaso yumye cyangwa yumye.

Ihumure: Amavuta yo kwisiga hamwe nubushuhe bwa HPMC agira uruhare muburyo bwiza bwo gutonyanga amaso. Ifasha kugabanya ibyiyumvo byo kwinuba, gutwika, no guhinda, bigatuma ijisho ritonyanga neza gukoresha.

Guhuza: HPMC ni biocompatable kandi yihanganira neza n'amaso, bigatuma ikoreshwa muburyo bwo kuvura amaso. Ntabwo itera kurakara cyangwa kwitwara nabi iyo ikoreshejwe hejuru ya ocular, itanga umutekano no guhumuriza uyikoresha.

Kutagira imiti igabanya ubukana: HPMC irashobora gukoreshwa muburyo bwo kubika amaso adafite imiti igabanya ubukana, bikunze gukundwa nabantu bafite amaso yunvikana cyangwa abafite ingaruka ziterwa na allergique kubibungabunga. Ibi bituma HPMC ikwiriye gukoreshwa muburyo butandukanye bwo kwita kumaso.

Hydroxypropyl methylcellulose (HPMC) igira uruhare runini mugutonyanga amaso itanga amavuta, kongera ububobere, kugumana, kurinda, guhumuriza, no guhuza. Imikoreshereze yacyo igira uruhare mu mikorere n’umutekano by’amaso, bitanga ihumure kubantu barwaye amaso yumye, kurakara, no kutamererwa neza.
