Daim Ntawv Thov Hydroxypropyl Methylcellulose (HPMC) ua ib qho Tshuaj Excipient hauv Kev Npaj

1. Cov khoom siv tshuaj lom neeg ntawm HPMC

HPMC yog cov khoom siv polymer semi-synthetic tau los ntawm methylating thiab hydroxypropylating natural cellulose, nrog rau kev yaj dej zoo heev thiab biocompatibility. Nws qhov kev yaj tsis cuam tshuam los ntawm qhov kub thiab pH, thiab nws tuaj yeem o hauv dej los ua cov kua nplaum, uas pab tswj kev tso tawm tshuaj. Raws li viscosity, HPMC tuaj yeem muab faib ua peb pawg: viscosity qis (5-100 mPa · s), viscosity nruab nrab (100-4000 mPa · s) thiab viscosity siab (4000-100000 mPa · s), uas tsim nyog rau ntau yam kev xav tau npaj.

2. Daim ntawv thov ntawm HPMC hauv kev npaj tshuaj

2.1 Daim ntawv thov hauv cov ntsiav tshuaj
HPMC tuaj yeem siv los ua cov khoom siv khi, cov khoom tawg, cov khoom siv txheej thiab cov khoom siv pob txha tswj hwm hauv cov ntsiav tshuaj.
Cov Ntawv Txuas:HPMC tuaj yeem siv los ua tus binder hauv cov granulation ntub lossis cov granulation qhuav los txhim kho lub zog ntawm cov khoom me me, cov ntsiav tshuaj tawv thiab kev ruaj khov ntawm cov tshuaj.
Ua kom tawg:HPMC uas muaj viscosity tsawg tuaj yeem siv los ua cov tshuaj disintegrant los txhawb kev tawg ntawm cov ntsiav tshuaj thiab ua rau cov tshuaj yaj sai dua tom qab o vim yog kev nqus dej.
Cov khoom siv txheej:HPMC yog ib qho ntawm cov ntaub ntawv tseem ceeb rau kev txheej ntsiav tshuaj, uas tuaj yeem txhim kho qhov tsos ntawm cov tshuaj, npog qhov saj tsis zoo ntawm cov tshuaj, thiab tuaj yeem siv rau hauv kev txheej enteric lossis txheej zaj duab xis nrog cov yas.
Cov khoom siv tswj tau tso tawm: HPMC uas muaj viscosity siab siv tau ua cov khoom siv pob txha los ncua kev tso tawm tshuaj thiab ua tiav kev tso tawm tshuaj mus tas li lossis tswj tau. Piv txwv li, HPMC K4M, HPMC K15M thiab HPMC K100M feem ntau siv los npaj cov ntsiav tshuaj tswj tau tso tawm.

2.2 Daim ntawv thov rau kev npaj tshuaj ntsiav
HPMC siv tau los tsim cov tshuaj ntsiav uas tsis muaj qab hau los hloov cov tshuaj ntsiav gelatin, uas tsim nyog rau cov neeg tsis noj nqaij thiab cov neeg uas ua xua rau cov tshuaj ntsiav uas muaj qab hau los ntawm tsiaj. Tsis tas li ntawd, HPMC siv tau rau kev sau cov kua lossis cov tshuaj ntsiav semisolid kom txhim kho kev ruaj khov thiab tso tawm cov yam ntxwv ntawm cov tshuaj.

2.3 Daim ntawv thov rau kev npaj kho qhov muag
HPMC, ua cov khoom tseem ceeb ntawm cov kua muag dag, tuaj yeem ua rau cov tshuaj qhov muag viscosity nce ntxiv, ua kom lub sijhawm nyob ntawm cov tshuaj ntawm qhov muag ntev dua, thiab txhim kho kev siv tau. Tsis tas li ntawd, HPMC kuj tseem siv tau los npaj cov tshuaj qhov muag gels, zaj duab xis qhov muag, thiab lwm yam, los txhim kho cov nyhuv tso tawm ntawm cov tshuaj qhov muag.

2.4 Kev siv rau kev npaj tshuaj rau sab nraud
AnxinCel®HPMC muaj cov khoom zoo rau kev tsim cov zaj duab xis thiab kev sib haum xeeb ntawm lub cev, thiab siv tau los npaj cov ntawv nplaum, cov gels thiab cov tshuaj pleev rau ntawm daim tawv nqaij. Piv txwv li, hauv cov txheej txheem xa tshuaj rau ntawm daim tawv nqaij, HPMC tuaj yeem siv ua cov khoom siv matrix los ua kom cov tshuaj nkag mus rau hauv daim tawv nqaij ntau dua thiab ua kom lub sijhawm ua haujlwm ntev dua.
