Hydroxypropyl methylcellulose (HPMC) ni polymer zitandukanye kandi zitandukanye kandi zikoreshwa mubikorwa bitandukanye, harimo imiti, ibiryo, ubwubatsi, no kwisiga.Ifumbire ikomoka kuri selile kandi ihindurwa hakoreshejwe imiti kugirango yongere imiterere yayo.
1. Imiterere yimiti nimiterere ya hydroxypropyl methylcellulose:
HPMC ni igice cya sintetike ya polymer yabonetse muguhindura selile karemano wongeyeho oxyde ya propylene na chloride ya methylene.Urwego rwo gusimbuza (DS) no gusimbuza umubyimba (MS) nibintu byingenzi byerekana imiterere ya HPMC.Ibipimo byerekana urwego rwa hydroxypropyl hamwe na metxy yo gusimbuza umugongo wa selile.
Imiterere yimiti ya HPMC iha polymer urutonde rwibintu byifuzwa.Nibikoresho bya hydrophilique bifite ubushobozi bwiza bwo gufata amazi, bigatuma bikenerwa mubikorwa bitandukanye aho gucunga neza ari ngombwa.Byongeye kandi, HPMC ifite imiterere yo gukora firime, ningirakamaro mu nganda nka farumasi n’imyenda.
2. Gusaba ubuvuzi:
HPMC ikoreshwa cyane mu nganda zimiti bitewe nubuzima bwa biocompatibilité, nontoxicity, nubushobozi bwo guhindura ibiyobyabwenge.Bikunze gukoreshwa mugutegura umunwa ukomeye wa dosiye nkibinini na capsules.Kugenzura ibiyobyabwenge bigenzurwa niyi dosiye bigerwaho muguhindura ibibyimba no kubyimba bya HPMC.
Byongeye kandi, HPMC ikoreshwa nka binder, disintegrant, na firime coating agent muburyo bwa tablet.Imiterere yacyo ya firime yorohereza iterambere ryimyenda yongerera imbaraga ibiyobyabwenge, uburyohe bwa mask, kandi itanga uburyo bwo kurekura.Guhuza polymer nibintu bitandukanye bikora imiti (APIs) bituma iba amahitamo menshi kubashinzwe gukora.
3. Inganda zubaka:
Mu nganda zubaka, HPMC ikoreshwa cyane nkumubyimba wibicuruzwa bishingiye kuri sima.Itezimbere imikorere kandi ihamye ya minisiteri na plaster, igabanya kugabanuka no kongera gufatira hamwe.Ibikoresho bigumana amazi ya HPMC birinda imvange ya sima gukama vuba, bigatuma habaho amazi meza ya sima kandi bigatera imbere imbaraga.
HPMC ikoreshwa kandi mubikoresho bifata tile, grout hamwe no kuringaniza ibice.Uruhare rwayo muri izi porogaramu zirimo kugenzura ububobere, gutanga igihe cyiza cyo gufungura, no kunoza imikorere rusange yibikoresho byubaka.
4. Inganda zibiribwa:
HPMC yemerewe gukoreshwa mu nganda y'ibiribwa nk'inyongeramusaruro (E464).Muri iki gihe, ikora nk'ibyimbye, stabilisateur na emulisiferi mu biribwa bitandukanye.HPMC ihabwa agaciro cyane cyane kubushobozi bwayo bwo gukora geles, kunoza imiterere no guhagarika ifuro mubiribwa.
Ibikoresho bigumana amazi ya HPMC bituma bigira akamaro mubicuruzwa byokerezwamo imigati, ibiryo byamata nisosi.Byongeye kandi, imiterere yama firime irashobora gukoreshwa mugukora firime ziribwa hamwe nudusanduku kugirango tunoze isura nubuzima bwibiryo bimwe.
5. Amavuta yo kwisiga n'ibicuruzwa byawe bwite:
Mu mavuta yo kwisiga no kwita ku muntu ku giti cye, HPMC ikoreshwa mu bicuruzwa bitandukanye, birimo amavuta, amavuta yo kwisiga, shampo n'ibicuruzwa bitunganya imisatsi.Ubushobozi bwayo bwo gukora firime bufasha gukora neza kurinda uruhu n umusatsi.
HPMC ihabwa agaciro kubera uruhare rwayo rwo guhindura umubyimba na rheologiya, itanga imiterere yifuzwa hamwe nubwiza bwo kwisiga.Ifasha kandi guhagarika emulisiyo, gukumira gutandukanya ibyiciro no kunoza ituze rusange ryamavuta yo kwisiga.
6. Ingaruka nibyiza:
Kubika Amazi: Kimwe mu byiza byingenzi bya HPMC nubushobozi bwayo bwiza bwo gufata amazi.Uyu mutungo ningirakamaro mubisabwa aho gucunga neza ari ngombwa, nka farumasi nibikoresho byubwubatsi.
Imiterere ya Firime: Imiterere ya firime ya HPMC yorohereza iterambere ryimyenda itanga uburinzi, irekurwa ryagenzuwe, hamwe nuburanga bwiza muburyo butandukanye.
Guhindura umubyimba na Rheologiya: HPMC irazwi cyane kubushobozi ifite bwo kongera ibisubizo no guhindura imiterere ya rheologiya.Ibi bituma bigira agaciro mu nganda aho kugenzura ibicucu ari ngombwa.
Biocompatibilité: Mubikorwa bya farumasi no kwisiga, biocompatibilité ya HPMC ninyungu zingenzi.Mubisanzwe byihanganirwa nabantu, bigatuma bikoreshwa mugukoresha ibicuruzwa byubuyobozi cyangwa umunwa.
Guhinduranya: Guhindura HPMC bigaragarira mubikorwa byinshi byinganda mubikorwa bitandukanye.Guhuza nibindi bikoresho no koroshya kwinjizwa mubikorwa bituma ikundwa.
7. Ibibazo n'ibitekerezo:
Hydrophilicity: Mugihe hydrophilicity ya HPMC ari akarusho mubikorwa byinshi, irashobora kwerekana imbogamizi muburyo bumwe na bumwe aho ikibazo cyo kumva amazi giteye impungenge.
Ubushyuhe bukabije: Imikorere ya HPMC iterwa nubushyuhe kandi imikorere yayo irashobora gutandukana mubihe bitandukanye ibidukikije.Abashinzwe gutegura bakeneye gusuzuma ibi bintu mugihe bategura formulaire.
Igiciro: Rimwe na rimwe, ikiguzi cya HPMC gishobora kwitabwaho, cyane cyane mu nganda aho ibikorwa-bikoreshwa neza.
8. Umwanzuro:
Hydroxypropyl methylcellulose ni polymer itandukanye igira uruhare runini mu nganda nyinshi zirimo imiti, ubwubatsi, ibiryo na cosmetike.Ihuza ryihariye ryumutungo, harimo kubika amazi, imiterere ya firime hamwe nuburyo bwinshi, bituma iba ikintu cyingirakamaro mubikorwa bitandukanye.Imikorere ya HPMC mugutanga ibiyobyabwenge, ibikoresho byubwubatsi, ibiryo no kwita kumuntu byerekana akamaro kayo mubikorwa bigezweho.
Mugihe inganda zikomeje gutera imbere, hakenewe polymers ikora kandi yizewe nka HPMC birashoboka.Imbaraga zikomeje gukorwa niterambere ryiterambere birashoboka ko bizarushaho kunoza imikorere nimikorere ya HPMC, bikomeza akamaro kayo mubice bitandukanye.Ubwanyuma, ingaruka nibikorwa bya hydroxypropyl methylcellulose byerekana ingaruka ibikoresho bishya bishobora kugira mugutezimbere inganda zitandukanye.
