Hydroxypropyl methylcellulose (HPMC)ni eteri ya cellulose itari ionic ifite ubushobozi bwo guhuza neza ibintu, ihamye mu binyabutabire, kandi ikora filime. Ikoreshwa cyane mu nganda zikora imiti mu binini, mu makapisule, muri gels, mu nganda zikoreshwa mu gupima no mu gutunganya imiti. Nk'umuti wizewe kandi utari ufite uburozi, HPMC ihuza ibyiza bya polimeri karemano n'izikozwe mu nganda, bigatuma iba umusemburo w'ingenzi mu nganda zikora imiti zigezweho.
HPMC igira uruhare runini mu mikorere y'ibinini. Ikunze gukoreshwa nk'ibikoresho bifunga, bivamo aside, kandi bisiga. Nk'ibikoresho bifunga, HPMC yongera imbaraga zo gufatanya kw'uduce tw'ifu mu gihe cyo guteranya ibinini, igatuma ibinini bikomera kandi bigakomera. Byongeye kandi, ubushobozi bwayo bwo gutandukana no kubyimba butuma imiti isohoka mu nzira y'igifu. Iyo ikoreshejwe nk'ibikoresho bifunganya, agahu kabonerana cyangwa kabonerana kakozwe na HPMC gakuramo ubushuhe na ogisijeni neza, kakongera ubushobozi bwo gufatanya n'imiti. Uburyo bwayo bwiza bwo gukora firime, kurwanya aside, no kudakoresha uburyohe bituma iba ibikoresho byiza byo gusiganya gelatin.
HPMC igira uruhare runini mu mikorere yo gusohora imiti igenzurwa. Bitewe n'ubushobozi bwayo bwo kubyimba no gukora gel mu mazi, ikunze gukoreshwa nk'igikoresho cya matrix mu buryo bwo gusohora imiti igenzurwa cyangwa igenzurwa. Iyo ikinini kigeze ku mazi yo mu gifu, urwego rw'inyuma rwa HPMC rukora vuba uruzitiro rwa gel ya viscoelastic, aho umuti urekurwa buhoro buhoro binyuze mu gukwirakwira cyangwa gushonga, bigatuma irekurwa burundu. Mu guhindura urwego rwo gusimbuza (methoxy na hydroxypropoxy) hamwe n'uburemere bwa molekile ya HPMC, umuvuduko n'igihe cyo gusohora imiti bishobora kugenzurwa neza. Iyi miterere ni ingenzi cyane mu kuvura indwara zidakira nka umuvuduko ukabije w'amaraso, diyabete, n'indwara z'umutima, aho kugumana ingano y'imiti mu maraso ari ingenzi cyane.
Mu buryo bw'ingano ya capsule, HPMC ikoreshwa cyane nk'ibikoresho by'ibanze mu gusya ibishyimbo by'ibimera. Ugereranyije na capsule za gelatin gakondo, capsule za HPMC ntiziterwa n'inyamaswa, bigatuma zikwiriye abarya imboga gusa n'abadafite amategeko agenga amadini. Byongeye kandi, ntizishobora kwihanganira ihindagurika ry'ubushyuhe n'ubushuhe kandi zifite imbaraga nziza za mekanike n'ubushobozi bwo kuzifunga, bigatuma imiti ikomeza kubikwa neza. Capsule za HPMC zishobora kandi gusigwa n'udupira twacitse cyangwa twa enteric, bigatuma habaho igishushanyo mbonera cy'ahantu hatandukanye ho gusohora imiti.
HPMC ikoreshwa kandi mu mavuta yo mu maso no mu mavuta yo mu maso. Mu mavuta yo mu maso n'amata y'amaso, HPMC ikora nk'umuti uhindura ubushyuhe n'amavuta yo kwisiga, ikomeza gufata imiti ku buso bw'amaso, ikagabanya ibimenyetso by'amaso yumye kandi ikanoza uburyo imiti yinjirwamo. Mu mavuta yo mu maso, gel, cyangwa uduce duto, HPMC igaragaza ubushobozi bwiza bwo gukora firime no koroshya, bigatuma iba igikoresho cy'ingirakamaro cyo kongera uburyo imiti ifatana n'uruhu kandi ikarumbuka. Uburyo bwayo bwo kudatera umujinya kandi idatera ubwivumbure byatumye ikoreshwa cyane mu mavuta yo mu maso no mu mavuta yo mu maso.
Umutekano wa HPMC n'uburyo yangirika nabyo ni ingenzi cyane mu ikoreshwa ryayo rikwirakwira hose. Ntiyinjizwa cyangwa ngo ikoreshwe mu mubiri w'umuntu, ntabwo itera uburozi kandi ntitera allergie, kandi ivanwa mu mazi y'umubiri, byujuje ibisabwa ku bintu bikoreshwa mu miti byashyizweho n'imiti mpuzamahanga. Irahamye mu buryo bw'imiti, ntigira ingaruka ku miti myinshi, kandi igumana imiterere yayo haba mu duce duto twa aside na alkaline.
Hydroxypropyl methylcellulose, ifite imiterere yihariye y’umubiri n’imiti ndetse n’uburyo ikora neza mu buzima, igaragaza akamaro kayo mu rwego rw’imiti. Kuva ku binini kugeza ku buryo bwo kugenzura, kuva ku bikombe bya capsule kugeza ku miti ikoreshwa mu gusiga,HPMCNtibituma imiti ikomeza guhagarara neza no kugenzura irekurwa ryayo gusa, ahubwo binatuma habaho udushya n'iterambere mu ikoranabuhanga rigezweho ryo gukora imiti. Uko inganda z'imiti zigenda zitera imbere zigana ku miti ishimishije, yizewe kandi isobanutse neza, amahirwe yo gukoresha HPMC azakomeza kwaguka, bigatuma iba ingenzi mu bikoresho by'imiti bikora neza cyane.
