Pharmaceutical Qib HPMC
Pharmaceutical qib HPMCHydroxypropyl methylcellulose yog dawb los yog milky dawb, tsis muaj ntxhiab, tsis qab, fibrous hmoov los yog granule, qhov hnyav poob ntawm ziab tsis tshaj 10%, soluble nyob rau hauv dej txias tab sis tsis kub dej, maj mam nyob rau hauv dej kub o, peptization, thiab tsim ib tug viscous colloidal tov. , uas dhau los ua kev daws teeb meem thaum txias, thiab dhau los ua gel thaum rhuab. HPMC yog insoluble hauv ethanol, chloroform thiab ether. Nws yog soluble nyob rau hauv ib qho hnyav hnyav ntawm methanol thiab methyl chloride. Nws kuj yog soluble hauv cov kuab tshuaj sib xyaw ntawm acetone, methyl chloride thiab isopropanol thiab qee cov kuab tshuaj organic. Nws cov tshuaj aqueous tuaj yeem tiv taus ntsev (nws cov tshuaj colloidal tsis raug puas tsuaj los ntawm ntsev), thiab pH ntawm 1% aqueous tov yog 6-8. Cov mis mos molecular ntawm HPMC yog C8H15O8-(C10H18O6) -C815O, thiab cov txheeb ze molecular loj yog li 86,000.

Nta thiab Cov txiaj ntsig:
HPMC muaj dej solubility zoo heev hauv dej txias. Nws tuaj yeem yaj mus rau hauv cov tshuaj pob tshab nrog me ntsis nplawm hauv dej txias. Ntawm qhov tsis sib xws, nws yog qhov yooj yim insoluble hauv dej kub tshaj 60℃thiab tsuas tuaj yeem o. Nws yog non-ionic cellulose ether. Nws cov tshuaj tsis muaj ionic nqi, tsis cuam tshuam nrog hlau ntsev los yog ionic organic tebchaw, thiab tsis hnov mob nrog lwm cov ntaub ntawv raw thaum lub sij hawm npaj; nws muaj zog los tiv thaiv rhiab heev, thiab raws li qib ntawm kev hloov pauv hauv cov qauv molecular nce, nws muaj zog tiv thaiv kev ua xua thiab ruaj khov dua; Nws tseem yog metabolically inert. Raws li ib tug kws tshuaj excipient, nws tsis yog metabolized los yog absorbed. Yog li ntawd, nws tsis muab cua sov hauv cov tshuaj thiab khoom noj. Nws yog cov calories tsawg, tsis muaj ntsev, thiab tsis muaj ntsev-dawb rau cov ntshav qab zib. Cov tshuaj tsis haum thiab cov khoom noj muaj qhov tshwj xeeb siv tau; Nws yog qhov ruaj khov rau cov kua qaub thiab alkalis, tab sis yog tias PH tus nqi siab tshaj 2 ~ 11 thiab cuam tshuam los ntawm qhov kub thiab txias dua lossis muaj lub sijhawm cia ntev dua, nws cov viscosity yuav txo; nws cov tshuaj aqueous tuaj yeem muab cov dej num hauv qhov chaw, qhia qhov nro nruab nrab ntawm qhov nro thiab qhov cuam tshuam ntawm qhov nro; nws muaj emulsification zoo nyob rau hauv ob-theem systems, yuav siv tau raws li ib tug zoo stabilizer thiab tiv thaiv colloid; nws cov tshuaj aqueous muaj cov yeeb yaj kiab zoo heev, thiab yog cov ntsiav tshuaj thiab ntsiav tshuaj Cov khoom siv zoo. Cov zaj duab xis txheej tsim los ntawm nws muaj qhov zoo ntawm cov xim tsis muaj xim thiab toughness. Ntxiv glycerin tuaj yeem txhim kho nws cov yas.
