Hydroxypropyl methylcellulose (HPMC) ni ibintu byinshi byimiti ikoreshwa cyane mubikorwa byinganda. Nibintu bitari ionic selulose ether, ahanini biboneka muguhindura imiti ya selile naturel. Ibigize shingiro ni uko amatsinda ya hydroxyl muri molekile ya selile asimburwa na mikorobe na hydroxypropyl. HPMC ikoreshwa cyane mubice byinshi nko kubaka, gutwikira, ubuvuzi, ibiryo, no kwisiga kubera imiterere yihariye yumubiri nubumara.
1. Imiterere yumubiri nubumara
HPMC ifite amazi meza kandi irashobora gushonga vuba mumazi akonje kugirango ibe igisubizo kiboneye cyangwa cyamata yoroheje. Igisubizo cyacyo cyamazi gifite ubukonje bwinshi, kandi ubukonje bwacyo bujyanye nubushuhe, ubushyuhe nintera yo gusimbuza igisubizo. HPMC ihagaze neza mugace ka pH kandi ifite kwihanganira acide na alkalis. Mubyongeyeho, ifite firime nziza cyane yo gukora, gufatira hamwe, gufata amazi no kubyimba.
2. Gahunda yumusaruro
Ibikorwa byo gukora HPMC bikubiyemo ahanini intambwe nko kuvura alkali, reaction ya etherification na nyuma yo kuvurwa. Ubwa mbere, selile naturel isanzwe itegurwa mugihe cya alkaline kugirango ikore, hanyuma igashyirwa hamwe na mikorobe ikoreshwa na hydroxypropylating, hanyuma amaherezo ibicuruzwa byanyuma biboneka binyuze mukutabogama, gukaraba, gukama no kumenagura. Mugihe cyo kubyara umusaruro, ibintu byifata nkubushyuhe, umuvuduko, igihe cyo kubyitwaramo nubunini bwa reagent zitandukanye bizagira ingaruka kumiterere no mumikorere ya HPMC.
3. Imirima yo gusaba
3.1 Inganda zubaka
Mu nganda zubaka, HPMC ikoreshwa cyane cyane mubyimbye, binder hamwe nogusigarana amazi ya sima. Irashobora kunoza imikorere, imikorere yubwubatsi hamwe nimbaraga zihuza za minisiteri, mugihe kugabanya kugabanuka no guturika kwa minisiteri.
3.2 Inganda
HPMC ikoreshwa nkibyimbye, ikwirakwiza na stabilisateur mu nganda zitwikiriye. Irashobora kunonosora imiterere yimiterere yikibiriti, ikoroshya gukaraba, kandi igateza imbere hamwe nuburinganire.
3.3 Inganda zimiti n’ibiribwa
Mu rwego rwa farumasi, HPMC ikoreshwa nkibikoresho bikora firime, umukozi urekura-uhoraho hamwe na stabilisateur kubinini byibiyobyabwenge. Irashobora kugenzura igipimo cyo kurekura ibiyobyabwenge no guteza imbere ibiyobyabwenge. Mu nganda z’ibiribwa, HPMC ikoreshwa nk'inyongera mu kubyimba, kwigana, guhagarika no guhagarika ibiryo.
3.4 Inganda zo kwisiga
Mu kwisiga, HPMC ikoreshwa nkibyimbye, firime yahoze hamwe na stabilisateur. Irashobora kuzamura imiterere nuburambe bwo kwisiga, no kunoza ituze hamwe nubushuhe bwibicuruzwa.
4. Ibyiza n'ibibazo
Nka miti itandukanye ikora, HPMC yerekanye ibyiza byo gukoresha mubikorwa bitandukanye byinganda. Ubwa mbere, ikomoka kuri selile karemano kandi ifite biocompatibilité nziza hamwe no kurengera ibidukikije. Icya kabiri, HPMC ifite imiti ihamye kandi irashobora gukomeza imikorere yayo mubihe bitandukanye bidukikije. Nyamara, inzira yo gukora HPMC iragoye kandi ifite ibisabwa byinshi mubikoresho byikoranabuhanga nikoranabuhanga. Mubyongeyeho, ubuziranenge buhoraho hamwe nibikorwa bihamye hagati yibicuruzwa bitandukanye nabyo nibibazo bikeneye kwitabwaho.
5. Iterambere ry'ejo hazaza
Hamwe niterambere rya siyanse nikoranabuhanga hamwe nimpinduka zikenewe ku isoko, ibyifuzo bya HPMC bizaba binini. Mubikorwa byubwubatsi, HPMC izagira uruhare runini mubikoresho bishya byubaka ninyubako zicyatsi. Mu rwego rw'ubuvuzi n'ibiribwa, HPMC izakoreshwa cyane uko ubuzima n'umutekano bizamuka. Byongeye kandi, nkuko abantu bitondera cyane kurengera ibidukikije n’iterambere rirambye, HPMC, nkumutungo ushobora kuvugururwa, izerekana ibyiza by’ibidukikije mu nzego nyinshi.
Hydroxypropyl methylcellulose (HPMC) yabaye ibikoresho byingenzi bya shimi mu musaruro w’inganda kubera imiterere yihariye n’imirima yagutse. Mu bihe biri imbere, hamwe n’iterambere rikomeje gutera imbere mu ikoranabuhanga no gukomeza kwagura ibikorwa, HPMC izagira uruhare runini mu nzego nyinshi, izana amahirwe mashya n’imbogamizi mu iterambere ry’inganda zitandukanye.
