Hypromellose madontho a maso

Hydroxypropyl methylcellulose (HPMC) amagwiritsidwa ntchito kwambiri popanga madontho a m'maso chifukwa amatha kuchita ngati mafuta owonjezera komanso mafuta. Madontho a m'maso omwe ali ndi HPMC nthawi zambiri amagwiritsidwa ntchito pochotsa maso owuma komanso kupereka mpumulo kwakanthawi kukwiya komanso kusapeza bwino.

Limagwirira ntchito HPMC mu diso madontho zachokera mphamvu yake kupanga zoteteza filimu padziko diso. Firimuyi imathandiza kusunga chinyezi ndikuletsa kutuluka kwa misozi, zomwe zingayambitse kuuma ndi kusapeza bwino. Kuonjezera apo, mafuta opangira mafuta a HPMC amathandizira kuchepetsa kukangana pakati pa chikope ndi pamwamba pa diso, zomwe zingathe kuchepetsa kukhumudwa.

Madontho a maso a HPMC amapezeka mosiyanasiyana komanso mosiyanasiyana, kutengera zosowa za wodwalayo. Madonthowa amatha kukhala ndi zinthu zina, monga zosungira ndi zoteteza, kuti ziwongolere magwiridwe antchito awo komanso kukhazikika. PH ya madontho imayendetsedwanso mosamala kuti iwonetsetse kuti imalekerera bwino ndipo sizimayambitsa kupsa mtima kapena kuwononga diso.

Kugwiritsa ntchito madontho a maso a HPMC, odwala nthawi zambiri amathira dontho limodzi kapena awiri m'diso lililonse ngati pakufunika. Madonthowa amatha kugwiritsidwa ntchito kangapo patsiku, malingana ndi kuopsa kwa zizindikirozo. Odwala ayenera kupewa kukhudza nsonga ya dontho m'diso lawo kapena malo ena aliwonse kuti apewe kuipitsidwa ndi madonthowo.

Ponseponse, madontho a maso a HPMC ndi njira yotetezeka komanso yothandiza pakupumula kwa maso owuma ndi zizindikiro zina zakupsa mtima. Amapereka mafuta odzola komanso oteteza omwe angathandize kuchepetsa kukhumudwa komanso kulimbikitsa machiritso a ocular. Odwala ayenera kukambirana ndi achipatala kuti adziwe chithandizo choyenera kwambiri cha matenda awo enieni.
