Kāwai: rauemi whakakikorua; rauemi membrane; Ko nga rauemi polymer tere-whakahaere mo nga whakaritenga tuku puhoi; Kaitohu whakau; He awhina whakatara, whakapiri papa; He kaihoko adhesion whakakaha.
1. Hua whakataki
KO TE HUA TENEI HUA KO TE IONIC CELLULOSE ETHER, ka kitea i waho he paura ma, he hongi me te kore reka, he wairewa i roto i te wai me te nuinga o nga whakarewa pararopi polar, e pupuhi ana i te wai matao ki te whakamotitia, ki te wairewa colloidal paku noa ranei. Ko te wairewa wai he mahi mata, he tino marama me te mahi pumau. Kei a HPMC te taonga o te kiri wera. Whai muri i te whakamahana, ka hangaia e te wairewa wai te wai o te wai o te hua i te rerenga wai, ka rewa i muri i te whakamatao. He rereke te pāmahana reera o nga whakaritenga rereke. Ko nga huringa o te wairewa me te viscosity, te iti o te viscosity zhao, ko te nui ake o te whakarewatanga, he rereke nga whakaritenga o nga taonga HPMC, ko te HPMC kua rewa ki te wai kaore e pa ki te uara pH.
Ko te pāmahana ngingiha mahorahora, te kiato wewete, te kiato pono me te pāmahana whakawhiti karaihe ko 360 ℃, 0.341g/cm3, 1.326g/cm3 me 170 ~ 180 ℃, ia. I muri i te whakamahana, ka huri parauri ki te 190 ~ 200 ° C ka wera ki te 225 ~ 230 ° C.
Ko te HPMC he tata kore e rewa i roto i te chloroform, te ewaro (95%), me te diethyl ether, ka rewa ki roto i te ranunga o te ewaro me te methylene chloride, te ranunga o te methanol me te methylene chloride, me te ranunga o te wai me te waihano. Ko etahi o nga taumata o te HPMC ka whakarewahia i roto i nga ranunga o te acetone, methylene chloride, me te 2-propanol, me etahi atu whakarewa pararopi.

2. Nga waahanga hua
2.1 Ka rewa te Hydroxypropyl methylcellulose ki te wai matao hei hanga i te wairewa colloidal viscous. I te mea ka taapirihia ki te wai matao me te whakaoho paku, ka taea te rewa ki te otinga marama. Engari, karekau e rewa i roto i te wai wera i runga ake i te 60 ℃ ka pupuhi noa. I roto i te whakaritenga o te wairewa wai hydroxypropyl methicellulose, he pai ake te taapiri i tetahi waahanga o te hydroxypropyl methicellulose ki roto i te nui o te wai, kia kaha te whakaoho, kia wera ki te 80 ~ 90 ℃, katahi ka taapirihia te toenga hydroxypropyl methicellulose, ka mutu te whakamahi i te wai matao hei taapiri. ki te nui e hiahiatia ana.
2.2 Ko te Hydroxypropyl methylcellulose he ether cellulose kore-ionic, kaore tana otinga e kawe i te utu katote, kaore e pahekoheko ki nga tote whakarewa, ki nga pūhui waro katote ranei, kia kore ai te HPMC e tauhohe me etahi atu rauemi mata me nga taapiri i roto i te tukanga o te whakarite. hangahanga.
2.3 Hydroxypropyl methylcellulose he kaha anti-sensitivity, me te pikinga o te tohu whakakapinga i roto i te hanganga ngota, ka whakareihia ano te anti-sensitivity. Ko nga raau taero e whakamahi ana i te HPMC hei awhina he pai ake te kounga i roto i te waa whai hua atu i nga raau taero e whakamahi ana i etahi atu rongoa tuku iho (te maaka, te dextrin, te paura huka).
2.4 Ko te Hydroxypropyl methylcellulose he mokowhiti. I te mea he rongoa rongoa, kaore i te whakakorikorihia, i te ngongo ranei, na reira kaore i te wera i roto i nga raau taero me nga kai. He mea motuhake ki te uara pukoro iti, te tote-kore, nga raau taero kore-allergenic me te kai mo te hunga mate huka.
Ko te 2.5HPMC he tino pumau ki nga waikawa me nga turanga, engari ki te nui ake te pH ki te 2 ~ 11 ka pa ki te teitei ake o te pāmahana, te roa ake ranei o te waa rokiroki, ka whakaitihia te tohu o te maoa.
2.6 Ka taea e te wairewa wairewa Hydroxypropyl methylcellulose te whakakorikori i te mata, e whakaatu ana i nga uara o te mata ngawari me nga uara riipene atanga. He emulsification whai hua i roto i te pūnaha rua-wahanga, me te taea te whakamahi hei stabilizer whai hua me te colloid tiaki.
2.7 Hydroxypropyl methylcellulose wairewa wai he pai rawa nga ahuatanga hanga kiriata, a he mea whakakikorua pai mo nga papa me nga pire. Ko te membrane i hangaia e ia he kore tae, he uaua. Mena ka taapirihia te glycerol, ka taea te whakanui ake i te kirihou. I muri i te maimoatanga o te mata, ka marara te hua i roto i te wai makariri, a ka taea te whakahaere i te tere o te whakakore ma te huri i te taiao pH. Ka whakamahia i roto i nga whakaritenga tuku puhoi me nga whakaritenga kua pania ki te enteric.
3. Tono hua
3.1. Ka whakamahia hei kaapiri me te maataki pakaru
Ka whakamahia te HPMC ki te whakatairanga i te whakakorenga tarukino me te tohu o nga tono tuku, ka taea te rewa tika i roto i te whakarewa hei whakapiri, te iti o te pokey o te HPMC kua rewa i roto i te wai ki te hanga marama ki te rei riipi otinga colloid, papa, pire, granules i runga i te whakapiri me te pakaru. kaihoko, me te pokey teitei mo te kāpia, whakamahia anake na te momo rereke me nga whakaritenga rereke, ko te whanui ko te 2% ~ 5%.
Wairewa wai HPMC me tetahi kukū o te waihā hei hanga i te herenga hiato; Hei tauira: 2%HPMC wairewa wai i konatunatua ki te 55% wairewa waihano i whakamahia mo te pelleting o te amoxicillin capsules, kia piki ake te rewa toharite o nga kapene amoxicillin mai i te 38% ki te 90% kaore he HPMC.
Ka taea te hanga HPMC ki te whakapiri hiato me te kukū rereke o te slurry māngaro i muri i te whakakorenga; Ko te whakakorenga o nga papa erythromycin enteric-coated i piki mai i te 38.26% ki te 97.38% i te wa i whakakotahihia te 2% HPMC me te 8% starch.
2.2. Hangaia he mea paninga kiriata me nga mea hanga kiriata
Ko te HPMC hei rauemi whakakikorua wai-wairewa he ahuatanga e whai ake nei: te pokey otinga ngawari; He ngawari te tukanga whakakikorua; He taonga hanga kiriata pai; Ka taea te pupuri i te ahua o te waahanga, te tuhi; Ka taea te makuku; Ka taea te tae, te kakara whakatika. HE WHAKAMAHI TENEI HUA HEI KAUPAPA KAUPAPA KAUPAPA KAUPAPA KAUPAPA MO NGA TAPU ME NGA PIRE KAUPAPA KAUPAPA KAUPAPA, MO TE KAUPAPA KAUPAPA KAUPAPA KAUPAPA KAUPAPA KAUPAPA, KO TE WHAKAMAHI KAUPAPA KO TE 2%-5%.
2.3, hei māngai mātotoru me te kāpia tiaki colloidal

2.4, hei aukati, he mea tuku puhoi, he kaihoko tuku whakahaere me te kaihoko pore
Ka whakamahia te tauira pokey teitei o te HPMC ki te whakarite i nga kaitarai me nga apiha tuku whakahaere o nga papa tuku anga angiwi whakauru me nga papa tuku totika a te anga wai. Ko te tauira iti-pokey he kaihoko pore-inducing mo nga papa tuku-whakahaere, whakahaere-whakahaere ranei kia tere te whiwhi i te horopeta haumanu tuatahi o aua papa, ka whai muri i te tuku-a-te-whakahaere, te whakahaere-whakahaere ranei ki te pupuri i nga kohinga whai hua i roto i te toto.
2.5. Karepe me te matrix suppository
Ka taea te whakareri i nga whakangao wairere me nga whakaritenga whakapiri pekitiki ma te whakamahi i nga ahuatanga o te hanga hydrogel e whakamahia ana e te HPMC ki te wai.
2.6 Nga rauemi whakapiri koiora
I konatunatuahia te Metronidazole ki te HPMC me te polycarboxylethylene 934 i roto i te whakaranu hei hanga i nga papa tuku tuku koiora kei roto te 250mg. I whakaatuhia e te whakamatautau whakangao in vitro he tere te pupuhi o te whakareri i roto i te wai, a ko te tukunga o te raau taero i whakahaerehia e te whakamaarama me te whakangawari mekameka waro. Ko te whakatinanatanga kararehe i whakaatu ko te punaha tuku rongoa hou he nui nga ahuatanga o te piri koiora ki te mucosa sublingual bovine.
2.7, hei awhina whakatara
Ko te pokey HIGH o tenei hua he awhina whakatārewatanga pai mo te whakarite wai whakatārewatanga, ko tana inenga o mua ko te 0.5% ~ 1.5%.
