Ikoreshwa rya HPMC mu nganda zikora imiti

Hydroxypropyl methylcellulose (HPMC)ni eteri ya cellulose idafite ionic ikozwe muri cellulose karemano ya polymer binyuze mu guhindura imiti. Ifite ubushobozi bwo gushonga neza, ikorana neza n'ibinyabuzima kandi ikora filime. Bitewe n'umutekano wayo mwinshi n'uburozi buke, ikoreshwa cyane mu nganda zikora imiti nk'umusemburo w'ibinini, ibikoresho birekura burundu, ibikoresho byo gusiga, ibikoresho bya capsule, nibindi, kandi igira uruhare runini mu gutegura ibintu bikomeye, gutegura ibintu by'amazi no gutegura ibintu birekura neza.

1. Gukoresha HPMC mu binini

Nk'igikoresho cyo gufunga

Iyo HPMC ikoreshejwe nk'ikintu gifunga mu binini, akenshi yongerwamo mu buryo bw'amazi cyangwa ifu y'amazi ivanze n'inzoga, bishobora kunoza neza imbaraga zo guhuza hagati y'ifu y'imiti, bityo bikongera ubukana n'ubudahangarwa bw'ibinini. Muri icyo gihe, ishobora no kunoza imikorere y'ibinini n'imikorere yabyo, no kwemeza ko ibinini bihuye kandi bifite ubuziranenge bwo gushushanya.

Nk'umuntu witandukanyije n'abandi

Nubwo HPMC ifite ubukana runaka, ifite ubukana bwiza kandi ifata amazi ku rugero ruto, ishobora kwinjiza umutobe w'igifu cyangwa amazi vuba, kandi igatuma ibinini bishonga nyuma yo kwaguka. Kubwibyo, ubukana buke bwa HPMC bukunze gukoreshwa nk'uburyo bwo gushonga mu gutegura vuba.

Ibikoresho by'amagufwa birekura mu buryo bugenzurwa

HPMC ishobora gukora urwego rwa gel mu mazi yo mu gifu kugira ngo igabanye igipimo cy’amazi n’imiti bikwirakwira. Kubwibyo, ikoreshwa cyane mu gutegura ibinini birekura burundu, ibinini birekura bigenzurwa n’ibindi binini binywa. Akenshi ikoreshwa hamwe n’izindi polymer zikoresha amazi (nka PVP, carbomer, nibindi) kugira ngo ikore sisitemu ihamye yo kurekura imiti.

2. Gukoresha HPMC mu gusiga ibinini

HPMC ifite ubushobozi bwiza bwo gukora firime no gukorera mu mucyo, kandi ni kimwe mu bikoresho bikunze gukoreshwa mu gusiga firime ku binini. Ugereranyije n'isukari isanzwe cyangwa polimeri ishongeshwa n'amazi, firime ya HPMC ifite ibyiza bikurikira:

Ikorwa ryihuse rya firime, rigenda neza kandi ryiza;

Imikorere yo gusohora ishobora guhindurwa;

Uburinzi bwiza ku binini, burinda ubushuhe kandi burwanya ogisijeni;

Ishobora gukoreshwa hamwe n'ibindi bikoresho bya pulasitiki (nk'ibice bya PEG, triacetin, nibindi) kugira ngo ihindure uburyo urwego rwa filime ruhagaze neza;

Ishobora gushonga mu bintu bitandukanye (amazi, etanoli, ibinyabutabire bivanze n'amazi n'inzoga, nibindi), ikoreshwa mu buryo butandukanye bwo kuyitegura.

Gukingira HPMC bikunze gukoreshwa mu gutegura irangi ryo mu nda, irangi rituma irabagirana kandi rigakingira kugira ngo risa neza.

3. Gukoresha HPMC mu tunyangingo

Ibikoresho fatizo by'ibimera

HPMC ni ubwoko bwa selulosi bukomoka ku bimera, bushobora gusimbura gelatin nk'igikoresho cy'ingenzi cy'agashishwa ka capsule kugira ngo hakorwe "capsules z'ibimera". Ugereranyije na capsules za gelatin z'amatungo, capsules za HPMC zifite ibyiza bikurikira:

Nta bintu bigize inyamaswa, bikwiriye abarya inyama n'abantu bo mu madini runaka;

Ubudahangarwa bwinshi, ntibugira ingaruka ku bushyuhe n'ubushuhe;

Kugabanya hygroscopicity no gukomera kurushaho mu buryo bw'ikoranabuhanga, bikongera igihe imiti imara;

Byoroshye kuzuza no gufunga, bikwiranye n'ibikoresho byo kuzuza capsule neza cyane.

Ibikoresho byo gupfunyikamo udupira duto tw’ingufu duto (microcapsule) bigenzurwa

Muri sisitemu zimwe na zimwe zigenzurwa na microcapsule release, HPMC ishobora no gukoreshwa nk'ibikoresho byo ku rukuta, ikorana n'izindi polymer kugira ngo imiti igabanuke mu mubiri binyuze mu kugabanya ubunini n'umuvuduko wo gushonga.

4. Gukoresha HPMC mu gutegura amazi

Mu bitonyanga by'amaso, imiti inyobwa n'imiti ikoreshwa mu guteka, HPMC ikunze gukoreshwa nk'umuti ukomeza ubushyuhe, utuma umubiri uhora umeze neza kandi ufata neza:

Ibitonyanga by'amaso: HPMC ikoreshwa nk'amavuta yo kwisiga kugira ngo yongere igihe ibitonyanga by'amaso bimara ku buso bw'ijisho, yongere imikorere y'umuti, kandi igatuza ibimenyetso by'amaso yumye.

Imiti y'amazi inyobwa: yongera ubukana bw'umuti, yongera uburyohe, kandi ikarinda imvura kugwa.

Amavuta yo guteka ku ruhu: nka jeli, amavuta yo kwisiga, amavuta yo kwisiga, nibindi, HPMC ishobora kunoza imikorere yayo yo gusiga no gufatana kw'uruhu, kandi ikanoza ubunararibonye bw'umukoresha.

5. Ukwemeza umutekano n'amategeko agenga

HPMC ni umuti ugabanya ubukana bw’imiti wemewe na FDA na EU EMA, kandi wujuje ibisabwa na farumasi zitandukanye (nka USP, Ph. Eur., JP, nibindi). Ufite uburozi buke, ntushobora guhuza neza n’imiti, kandi ntutera allergie. Ni umuti ugabanya ubukana kandi ukoreshwa cyane mu kunywa no mu guteka imiti.

6. Iterambere ry'ejo hazaza rijyanye n'iterambere

Bitewe n’iterambere ry’ibitekerezo by’imiti ku bidukikije kandi bitangiza ibidukikije ndetse no kwiyongera kw’abarya imboga gusa, amahirwe yo gukoresha HPMC mu bimera bya capsules no mu gutegura imiti igenzurwa ni menshi. Ubushakashatsi ku miti igezweho ya HPMC (nk’iyahinduwe yihariye) mu gutanga imiti, gutanga imiti igenzurwa n’ubuhanga, n’ibindi, nabwo burimo kugenda burushaho gukora, ibi bikazatuma ikoreshwa mu bijyanye n’imiti igezweho.

Nk'igikoresho gifite imikorere myinshi kandi gifite umutekano mwinshiumuti ufasha mu gufata imiti HPMCIfite uruhare runini cyane mu nganda zikora imiti. Kuva ku bikoresho gakondo byo gusiga ndetse n'ibikoresho byo gusiga kugeza ku bikoresho bigezweho bigenzurwa n'ibikomoka ku bimera, ikoreshwa ryayo rikomeje kwaguka kandi ni kimwe mu bintu by'ingenzi mu gutegura imiti igezweho.
