HydroxyPropyl Methyl Cellulose mu Diso Drops

Hydroxypropyl methylcellulose (HPMC) amagwiritsidwa ntchito kwambiri m'madontho a m'maso chifukwa chopaka mafuta komanso ma viscoelastic. Nazi njira zina zomwe HPMC imagwiritsidwira ntchito m'maso:

Kupaka mafuta: HPMC imagwira ntchito ngati mafuta m'madontho a maso, kupereka chinyezi ndi mafuta pamwamba pa diso. Izi zimathandiza kuchepetsa kusapeza bwino kwa maso owuma pochepetsa kukangana pakati pa chikope ndi cornea.

Kupititsa patsogolo Viscosity: HPMC imawonjezera kukhuthala kwa madontho a diso, zomwe zimathandiza kutalikitsa nthawi yolumikizana ndi malo owoneka. Nthawi yotalikirapo iyi imawonjezera mphamvu ya madontho a diso pakunyowetsa ndi kutonthoza maso.

Kusunga: Mawonekedwe a viscous a HPMC amathandizira madontho a diso kumamatira kumtunda, kukulitsa nthawi yawo yosungira padiso. Izi zimathandiza kugawa bwino kwa zosakaniza zomwe zimagwira ntchito ndikuonetsetsa kuti hydration ndi mafuta ochuluka.

Chitetezo: HPMC imapanga filimu yoteteza pamwamba pa maso, ndikuyiteteza ku zowononga zachilengedwe ndi zowononga. Chotchinga chotetezachi chimathandizira kuchepetsa kukwiya komanso kutupa, kupereka mpumulo kwa anthu omwe ali ndi maso owuma kapena owuma.

Chitonthozo: Kupaka mafuta ndi kunyowa kwa HPMC kumathandizira kutonthoza kwa madontho a maso. Zimathandizira kuchepetsa kukhumudwa, kuyaka, ndi kuyabwa, zomwe zimapangitsa kuti madontho am'maso azikhala omasuka kugwiritsa ntchito.

Kugwirizana: HPMC ndi biocompatible ndi bwino kulolerana ndi maso, kupanga kukhala oyenera ntchito ophthalmic formulations. Sichimayambitsa kupsa mtima kapena zoyipa zikagwiritsidwa ntchito pamtunda, kuonetsetsa chitetezo ndi chitonthozo kwa wogwiritsa ntchito.

Zopangira Zopanda Zodzitetezera: HPMC ikhoza kugwiritsidwa ntchito popanga madontho opanda maso, omwe nthawi zambiri amakondedwa ndi anthu omwe ali ndi maso ozindikira kapena omwe amakonda kusagwirizana ndi zoteteza. Izi zimapangitsa HPMC kukhala yoyenera kugwiritsidwa ntchito pazinthu zosiyanasiyana zosamalira maso.

Hydroxypropyl methylcellulose (HPMC) imagwira ntchito yofunika kwambiri pakugwetsa m'maso popereka mafuta, kukulitsa kukhuthala, kusunga, chitetezo, chitonthozo, komanso kugwirizanitsa. Kugwiritsiridwa ntchito kwake kumathandizira kuti mawonekedwe a ophthalmic apangidwe komanso otetezeka, kupereka mpumulo kwa anthu omwe akuvutika ndi maso owuma, kuyabwa, ndi kusapeza bwino.
