1. Intangiriro yibanze ya HPMC
HPMC (Hydroxypropyl Methylcellulose)ni intungamubiri ya polymer ikomoka kuri selile naturel. Ikorwa cyane cyane no guhindura imiti ya selile kandi ikoreshwa cyane mubuvuzi, ibiryo, kwisiga no kubaka. Kuberako HPMC idashobora gukama amazi, idafite uburozi, uburyohe kandi idatera uburakari, yabaye ikintu cyingenzi mubicuruzwa byinshi.
Mu nganda zimiti, HPMC ikoreshwa kenshi mugutegura irekurwa rihoraho ryimiti yibiyobyabwenge, ibishishwa bya capsule, hamwe na stabilisateur kumiti. Irakoreshwa kandi cyane mubiribwa nkibibyimbye, emulifisiyeri, humectant na stabilisateur, ndetse ikoreshwa nkibigize karori nkeya mu mafunguro yihariye. Mubyongeyeho, HPMC nayo ikoreshwa nkibintu byimbitse kandi bitanga amazi mu kwisiga.
2. Inkomoko n'ibigize HPMC
HPMC ni selile ya selile yabonetse muguhindura imiti ya selile. Cellulose ubwayo ni polysaccharide ikurwa mu bimera, igize igice cyingenzi cyinkuta za selile. Mugihe cyo guhuza HPMC, amatsinda atandukanye akora (nka hydroxypropyl na methyl) atangizwa kugirango arusheho gukomera kwamazi no kubyimba. Kubwibyo, isoko ya HPMC ni ibikoresho bisanzwe byibimera, kandi uburyo bwo kubihindura bituma burushaho gushonga kandi butandukanye.
3. Gukoresha HPMC no guhura numubiri wumuntu
Urwego rw'ubuvuzi:
Mu nganda zimiti, imikoreshereze ya HPMC igaragarira cyane cyane mumyiteguro irekura-irekura. Kubera ko HPMC ishobora gukora geli kandi ikagenzura neza igipimo cyo kurekura ibiyobyabwenge, ikoreshwa cyane mugutezimbere imiti irekura-irekurwa kandi ikagenzurwa. Byongeye kandi, HPMC ikoreshwa kandi nk'igikonoshwa cya capsule ku biyobyabwenge, cyane cyane muri capsules y'ibimera (capsules y'ibikomoka ku bimera), aho ishobora gusimbuza gelatine gakondo kandi igatanga amahitamo akomoka ku bimera.
Urebye umutekano, HPMC ifatwa nkumutekano nkibigize ibiyobyabwenge kandi muri rusange bifite biocompatibilité nziza. Kubera ko idafite uburozi kandi idakangurira umubiri w'umuntu, FDA (Ikigo gishinzwe ibiryo n'ibiyobyabwenge muri Amerika) yemeje HPMC nk'inyongeramusaruro n'ibiyobyabwenge, kandi nta ngaruka z'ubuzima ziterwa no gukoresha igihe kirekire zabonetse.
Inganda zibiribwa:
HPMC ikoreshwa cyane mu nganda z’ibiribwa, cyane cyane nk'ibyimbye, stabilisateur, emulisiferi, n'ibindi. Ikoreshwa cyane mu biribwa byiteguye kurya, ibinyobwa, bombo, ibikomoka ku mata, ibiryo by'ubuzima n'ibindi bicuruzwa. HPMC ikoreshwa kandi mukubyara umusaruro muke wa calorie cyangwa ibinure bike kubera imiterere yabyo ikabura amazi, bitezimbere uburyohe nuburyo bwiza.
HPMC mu biribwa iboneka muguhindura imiti ya selile yibihingwa, kandi ubunini bwayo nimikoreshereze yabyo bigenzurwa cyane mubipimo ngenderwaho byo gukoresha inyongeramusaruro. Dukurikije ubushakashatsi bwa siyansi n’ubuziranenge bw’ibiribwa mu bihugu bitandukanye, HPMC ifatwa nk’umutekano ku mubiri w’umuntu kandi nta ngaruka mbi cyangwa ingaruka z’ubuzima.
Inganda zo kwisiga:
Mu kwisiga, HPMC ikoreshwa nkibintu byibyimbye, emulisiferi hamwe nubushuhe. Ikoreshwa cyane mubicuruzwa nka cream, isuku yo mumaso, amavuta yo kwisiga, lipstike, nibindi kugirango uhindure imiterere nibidukikije. Kubera ko HPMC yoroheje kandi idatera uruhu, ifatwa nkigikoresho kibereye ubwoko bwose bwuruhu, cyane cyane uruhu rworoshye.
HPMC ikoreshwa kandi mumavuta no gusana uruhu kugirango bifashe kuzamura ituze no kwinjira mubigize ibiyobyabwenge.
4. Umutekano wa HPMC kumubiri wumuntu
Isuzuma ry'uburozi:
Nk’ubushakashatsi buriho, HPMC ifatwa nk’umutekano ku mubiri w'umuntu. Ishami ry'Umuryango w'Abibumbye ryita ku Buzima (OMS), Ishami rishinzwe ibiribwa n'ubuhinzi (FAO), na FDA yo muri Amerika bose bakoze isuzuma rikomeye ku mikoreshereze ya HPMC kandi bemeza ko ikoreshwa mu buvuzi n'ibiribwa ku bitekerezo bitazagira ingaruka ku buzima bw'abantu. FDA itondekanya HPMC nk "ibintu bisanzwe bizwi ko bifite umutekano" (GRAS) kandi ikemerera gukoreshwa nk'inyongeramusaruro n'ibiyobyabwenge.
Ubushakashatsi ku mavuriro no gusesengura imanza:
Ubushakashatsi bwinshi bwubuvuzi bwerekanye koHPMCntabwo itera ingaruka mbi cyangwa ingaruka muburyo busanzwe bwo gukoresha. Kurugero, iyo HPMC ikoreshwa mugutegura imiti, abarwayi mubisanzwe ntibagaragaza allergie reaction cyangwa ibindi bitameze neza. Byongeye kandi, ntakibazo cyubuzima cyatewe no gukoresha cyane HPMC mubiryo. HPMC nayo ifatwa nkumutekano mubantu bamwe badasanzwe keretse niba hari reaction ya allergique kugiti cyayo.
Imyitwarire ya allergique n'ibisubizo bibi:
Nubwo HPMC idakunze gutera allergique, umubare muto wabantu bumva cyane barashobora kugira allergique kuri yo. Ibimenyetso byerekana ingaruka za allergique zishobora kuba zirimo gutukura uruhu, guhinda, no guhumeka neza, ariko ibibazo nkibi ni gake cyane. Niba gukoresha ibicuruzwa bya HPMC bitera ikibazo icyo ari cyo cyose, hagarika kuyikoresha ako kanya hanyuma ubaze muganga.
Ingaruka zo gukoresha igihe kirekire:
Gukoresha igihe kirekire HPMC ntabwo bizatera ingaruka mbi zizwi kumubiri wumuntu. Nk’uko ubushakashatsi buriho bubigaragaza, nta kimenyetso cyerekana ko HPMC izangiza ingingo nk'umwijima n'impyiko, nta nubwo izagira ingaruka ku mubiri w'umubiri cyangwa ngo itere indwara zidakira. Kubwibyo, gukoresha igihe kirekire HPMC bifite umutekano mubiribwa bihari na farumasi.
5. Umwanzuro
Nka compound ikomoka ku bimera bisanzwe bya selile, HPMC ikoreshwa cyane mubice byinshi nkubuvuzi, ibiryo ndetse no kwisiga. Umubare munini wubushakashatsi bwa siyansi hamwe nisuzuma ryuburozi bwerekanye ko HPMC ifite umutekano mugihe gikwiye gukoreshwa kandi nta burozi buzwi cyangwa ingaruka ziterwa na muntu. Haba mubitegura imiti, inyongeramusaruro cyangwa kwisiga, HPMC ifatwa nkibintu byizewe kandi byiza. Byumvikane ko, kugirango ukoreshe ibicuruzwa ibyo aribyo byose, amabwiriza ajyanye no gukoresha agomba gukomeza gukurikizwa, hagomba kwirindwa gukoreshwa cyane, kandi hagomba kwitabwaho cyane kubitekerezo bishobora kuba biterwa na allergique mugihe cyo kuyikoresha. Niba ufite ibibazo byubuzima bidasanzwe cyangwa impungenge, birasabwa kubaza umuganga cyangwa umunyamwuga.
