1. Chigadzirwa sumo
Ichi CHIKAMU IS A NON-IONIC CELLULOSE ETHER, kunze inoonekwa sehupfu chena, isinganhuhwi uye isinganakidze, inonyungudika mumvura uye yakawanda polar organic solvents, kuzvimba mumvura inotonhora kujekesa kana zvishoma turBIdized colloidal solution. Mushonga wemvura une basa repamusoro, kujeka kwepamusoro uye kushanda kwakagadzikana. HPMC ine pfuma yejeri rinopisa. Mushure mekupisa, chigadzirwa chine aqueous solution inoumba gel precipitation, uye inonyunguduka mushure mekutonhora. Iyo tembiricha yegel yezvakasiyana zvakasiyana zvakasiyana. Solubility inoshanduka ne viscosity, viscosity zhao yakaderera, iyo yakanyanya kunyungudika, zvakasiyana-siyana zveHPMC zvivakwa zvine mimwe misiyano, HPMC yakanyungudika mumvura haina kukanganiswa ne pH kukosha.
Iyo tembiricha yekupisa inongoerekana yavapo, yakasununguka density, density yechokwadi uye tembiricha yegirazi yekuchinja yaive 360 ℃, 0.341g/cm3, 1.326g/cm3 uye 170 ~ 180 ℃, zvichiteerana. Mushure mekupisa, inoshanduka shava pa190 ~ 200 ° C uye inopisa pa225 ~ 230 ° C.
HPMC inenge isinganyungudike muchloroform, ethanol (95%), uye diethyl ether, uye yakanyungudutswa mumusanganiswa we ethanol uye methylene chloride, musanganiswa wemethanol uye methylene chloride, uye musanganiswa wemvura uye ethanol. Mamwe mazinga eHPMC anonyungudika mumisanganiswa yeacetone, methylene chloride, uye 2-propanol, pamwe chete mune mamwe organic solvents.

2. Zvigadzirwa zvechigadzirwa
2.1 Hydroxypropyl methylcellulose inonyungudutswa mumvura inotonhora kuita viscous colloidal solution. Chero bedzi iyo yakawedzerwa kumvura inotonhora uye zvishoma inobvongodzwa, inogona kunyungudutswa mumhinduro yakajeka. Pane kudaro, haina kunyungudika mumvura inopisa pamusoro pe60 ℃ uye inogona kungozvimba. Mukugadzirira kwehydroxypropyl methiculose aqueous solution, zviri nani kuwedzera chikamu chehydroxypropyl methiccellulose mune imwe huwandu hwemvura, kubvongodza zvine simba, kupisa kusvika 80 ~ 90 ℃, uye wobva wawedzera yasara hydroxypropyl methiculose, uye pakupedzisira shandisa mvura inotonhora kuwedzera. kusvika pamari inodiwa.
2.2 Hydroxypropyl methylcellulose isiri-ionic cellulose ether, mhinduro yayo haitakuri ionic charge, haipindirani nesimbi yemunyu kana ionic organic compounds, kuitira kuti ive nechokwadi chokuti HPMC haiiti nezvimwe zvinhu zvakasvibirira uye zvinobatsira mukugadzirisa. production.
2.3 Hydroxypropyl methylcellulose ine simba rinopesana nekunzwa, uye nekuwedzera kwekutsiva dhigirii mukugadzirwa kwema molecular, anti-sensitivity inowedzerwawo. Mishonga inoshandisa HPMC sezvishandiso zvine hutsika hwakagadzikana mukati menguva inoshanda kupfuura zvinodhaka zvinoshandisa zvimwe zvechinyakare excipients (starch, dextrin, powdered sugar).
2.4 Hydroxypropyl methylcellulose ine metabolically inert. Semushonga wemishonga, haisi kushandiswa kwemasabolism kana kubatwa, saka haipi kupisa mumishonga uye zvokudya. Iyo ine yakasarudzika inoshanda kune yakaderera calorific kukosha, munyu-isina, isiri-allergenic zvinodhaka uye chikafu chevane chirwere cheshuga.
2.5HPMC haina kugadzikana kune maasidhi nemabhesi, asi kana pH ikadarika 2 ~ 11 uye ikakanganiswa netembiricha yepamusoro kana nguva yakareba yekuchengetedza, inoderedza dhigirii rekuibva.
2.6 Hydroxypropyl methylcellulose aqueous solution inogona kupa basa repamusoro, richiratidza mwero wepamusoro uye kupindirana kwehutano hwehutano. Iine emulsification inoshanda mune maviri-phase system uye inogona kushandiswa seyakasimba stabilizer uye inodzivirira colloid.
2.7 Hydroxypropyl methylcellulose aqueous solution ine yakanakisa kugadzira firimu zvinhu, uye yakanaka coating material yemapiritsi nemapiritsi. Iyo membrane inoumbwa nayo haina ruvara uye yakaoma. Kana glycerol yakawedzerwa, plastiki yayo inogona kuwedzerwa. Mushure mekurapwa kwepamusoro, chigadzirwa chinoparadzirwa mumvura inotonhora, uye chiyero chekunyungudika chinogona kudzorwa nekushandura pH nharaunda. Inoshandiswa mukunonoka-kusunungurwa kugadzirira uye enteric-coated kugadzirira.
3. Chigadzirwa chekushandisa
3.1. Inoshandiswa seanonamatira uye inoparadzanisa agent
HPMC inoshandiswa kusimudzira kuparara kwezvinodhaka uye dhigirii rekuburitsa zvikumbiro, inogona kunyungudika zvakananga mukunyungudika sekunamira, yakaderera viscosity yeHPMC yakanyungudika mumvura kuti iite pachena kune yenzou inonamira colloid mhinduro, mahwendefa, mapiritsi, granules pane adhesive uye disintegrated. mumiririri, uye iyo yakakwira viscosity yeglue, shandisa chete nekuda kwemhando dzakasiyana uye zvakasiyana zvinodiwa, general i2% ~ 5%.
HPMC aqueous solution uye imwe concentration ye ethanol kuita composite binder; Muenzaniso: 2% HPMC mvura yemushonga yakasanganiswa ne55% ethanol solution yakashandiswa kupeta macapsules eamoxicillin, kuitira kuti avhareji yekunyunguduka kweamoxicillin capsules iwedzere kubva pa38% kusvika 90% pasina HPMC.
HPMC inogona kugadzirwa necomposite adhesive ine dzakasiyana siyana ye starch slurry mushure mekuparara; Kunyungudutswa kwemapiritsi erythromycin ane enteric-coated kwakawedzera kubva pa38.26% kusvika pa97.38% pakasanganiswa 2% HPMC ne8% starch.
2.2. Gadzira firimu rekuvhara zvinhu uye firimu kugadzira zvinhu
