HPMC, cyangwa Hydroxypropyl Methylcellulose, ntabwo irinda ubwayo, ahubwo ni inyongeramusaruro ikoreshwa mu nganda zitandukanye, harimo imiti, ibiryo, amavuta yo kwisiga, n'ubwubatsi. Ikora imirimo myinshi nkibyimbye, emulisiferi, firime-yahoze, na stabilisateur, ariko ntabwo ikoreshwa cyane cyane kubibungabunga.
Kurinda ibintu ni ibintu byongewe ku bicuruzwa kugirango birinde mikorobe gukura no kwangirika. Nubwo HPMC itabuza mu buryo butaziguye imikurire ya mikorobe, irashobora kugira uruhare rutaziguye mu kubungabunga ibicuruzwa bimwe na bimwe ikora inzitizi ikingira cyangwa matrix, ishobora gufasha kuramba. Byongeye kandi, HPMC irashobora gukoreshwa ifatanije nuburinzi kugirango izamure imikorere cyangwa itezimbere muri rusange ibicuruzwa.
1.Iriburiro rya HPMC:
Hydroxypropyl Methylcellulose (HPMC) ni inkomoko ya selile, ikaba ari polymer karemano iboneka mu rukuta rw'utugingo ngengabuzima. HPMC ikomatanyirizwa hamwe hifashishijwe uburyo bwo guhindura imiti ya selile, aho hydroxypropyl na methyl matsinda byinjizwa mu mugongo wa selile. Ihinduka ritanga ibintu byihariye kuri HPMC, bigatuma bihinduka cyane kandi bifite akamaro muburyo butandukanye bwa porogaramu.
2.Umutungo wa HPMC:
Amazi meza: HPMC yerekana urugero rutandukanye rwo gukama kwamazi bitewe nuburemere bwa molekile hamwe nubunini bwo gusimburwa. Uyu mutungo utuma gutandukana byoroshye mubisubizo byamazi, bigatuma bikwiranye nibisabwa bisaba uburinganire n'ubwuzuzanye.
Gukora firime: HPMC irashobora gukora firime zibonerana kandi zoroshye mugihe zumye, bigatuma biba byiza mugukoresha ibikoresho bya farumasi ninganda zibiribwa.
Kubyimba: Imwe mumikorere yibanze ya HPMC nubushobozi bwayo bwo kubyimba ibisubizo byamazi. Itanga ubushishozi kumikorere, kunoza imiterere no guhuzagurika.
Gutuza: HPMC irashobora guhagarika emulisiyo mukurinda gutandukana kwicyiciro no kunoza ituze muri sisitemu ya colloidal.
Biocompatibilité: HPMC isanzwe ifatwa nkumutekano kugirango ikoreshwe mu miti yimiti, kwisiga, nibicuruzwa byibiribwa, kuko ishobora kwangirika kandi idafite uburozi.
3.Ibisabwa bya HPMC:
Imiti ya farumasi: Mu nganda zimiti, HPMC ikoreshwa cyane nkumuhuza mugutegura ibinini, kubyimbye muburyo bwa dosiye yamazi, umukozi wo gutwikira firime kubinini na capsules, hamwe na matrix irekura-yahoze.
Ibiryo: HPMC ikoreshwa mubicuruzwa byibiribwa nkibibyimbye, stabilisateur, na emulifier. Bikunze kuboneka mu isosi, imyambarire, ibikomoka ku migati, hamwe n’andi mata.
Amavuta yo kwisiga: Mu kwisiga, HPMC ikoreshwa muburyo bwo kwisiga nka cream, amavuta yo kwisiga, hamwe na geles kugirango itange ubwiza, yongere ubwiza, kandi ihagarike emulisiyo.
Ubwubatsi: HPMC ikoreshwa mubikoresho byubwubatsi nka minisiteri, plaster, hamwe nudukaratasi twa tile kugirango tunoze imikorere, gufata amazi, hamwe no gufatira hamwe.
4.HPMC no Kubungabunga:
Mugihe HPMC ubwayo idafite umutungo wo kubungabunga, imikoreshereze yayo irashobora kugira uruhare rutaziguye mu kubungabunga ibicuruzwa bimwe na bimwe:
Imikorere ya bariyeri: HPMC irashobora gukora inzitizi irinda ibintu bikora, ikabuza kwangirika kwayo bitewe nubushuhe, ogisijeni, cyangwa urumuri. Iyi bariyeri ifasha kongera igihe cyibicuruzwa bigabanya umuvuduko wo kwangirika kwimiti.
Guhindura ibyemezo: Mugutezimbere ubwiza nuburinganire bwimikorere, HPMC irashobora gufasha kugabura uburyo bumwe bwo kubika ibintu muri matrix yibicuruzwa. Ibi bituma habaho kubungabunga neza wirinda kwanduza mikorobe no gukura.
Kubangikanya no kubungabunga ibidukikije: HPMC irahujwe nubwoko butandukanye bwo kubika ibintu bikoreshwa mu miti yimiti, kwisiga, nibiribwa. Imiterere yacyo inert yemerera kwinjiza ibintu bitabangamiye ubunyangamugayo cyangwa imikorere yimikorere.
5.Imikoranire naba conservateurs:
Mugihe utegura ibicuruzwa bisaba kubungabungwa, nka farumasi cyangwa kwisiga, birasanzwe kwinjiza HPMC hamwe nudukingirangingo kugirango tugere kumutekano wifuzwa no kubaho neza. Imikoranire hagati ya HPMC nuburinzi irashobora gutandukana bitewe nibintu nkubwoko bwo kubungabunga, kwibanda, pH, nibisabwa byihariye.
Ingaruka zo Gukomatanya: Rimwe na rimwe, guhuza HPMC hamwe n’ibintu bimwe na bimwe birinda ibintu bishobora kwerekana ingaruka zifatika, aho ibikorwa rusange byo kubungabunga byongerewe imbaraga birenze ibyagerwaho n’ibice byonyine. Ubu bufatanye bushobora guturuka ku gukwirakwiza neza no kugumana ibintu birinda ibintu muri matrix.
pH Ibyiyumvo: Ibintu bimwe na bimwe birinda ibintu bishobora kwerekana ibikorwa biterwa na pH, aho imikorere yabyo iterwa na acide cyangwa alkaline ya formulaire. HPMC irashobora gufasha guhagarika pH yimikorere, kwemeza uburyo bwiza bwo kubungabunga ibidukikije.
Kwipimisha guhuza: Mbere yo kurangiza formulaire, hagomba gukorwa ibizamini byo guhuza kugirango harebwe imikoranire hagati ya HPMC nababigenewe. Ibi bikubiyemo gusuzuma ibipimo nkibikomeza kumubiri, mikorobe ikora neza, hamwe nubuzima bwa tekinike kugirango harebwe ubuziranenge numutekano byibicuruzwa.
Hydroxypropyl Methylcellulose (HPMC) ninyongeramusaruro inyuranye ikoreshwa mu nganda zinyuranye kugirango ibyimbye, ituze, kandi ikora firime. Mu gihe HPMC ubwayo atari uburyo bwo kubungabunga ibidukikije, kwinjizwa mu mikorere irashobora kugira uruhare rutaziguye mu kubungabunga ibicuruzwa mu gushyiraho inzitizi zo kubarinda, guhagarika imiterere, no kuzamura imikorere y’ibidukikije. Gusobanukirwa imikoranire hagati ya HPMC nuburinzi ningirakamaro mugutezimbere imiti ihamye kandi ikora neza mumiti yimiti, kwisiga, ibicuruzwa byibiribwa, nibindi bikorwa. Mugukoresha imitungo yihariye ya HPMC ifatanije nuburinda, abayikora barashobora kwemeza ubunyangamugayo, umutekano, nubuzima bwibicuruzwa byabo, byujuje ibyifuzo byabaguzi kumasoko yapiganwa uyumunsi.
