Disintegrant
Lub disintegrant yog ib qho ntxiv uas txhawb kev tawg, uas yog kev tawg ntawm cov ntsiav tshuaj mus rau hauv cov khoom me me thaum sib cuag nrog cov kua nruab nrab. Disintegrants thiab superdisintegrant excipients yog cov khoom siv tseem ceeb siv hauv kev lag luam kws tshuaj los txhim kho kev sib cais thiab bioavailability ntawm cov khoom xyaw tshuaj nquag (APIs). Cov excipients no pab txhawb kev tawg thiab tawg sai ntawm cov ntsiav tshuaj lossis tshuaj ntsiav, uas thaum kawg ua rau lawv qhov kev nqus ntawm lub cev.
Qhov zoo ntawm Disintegrant
Capillary kev ua
Hom disintegrant no tuaj yeem tswj xyuas qhov pore qauv ntawm cov ntsiav tshuaj compressed hauv cov ntsiav tshuaj, tsim cov kab capillary uas yooj yim rau ntub thiab nthuav tawm qhov qis ntawm qhov sib txuam hauv qhov nruab nrab aqueous. Thaum cov ntsiav tshuaj muab tso rau hauv dej, dej tuaj yeem nkag mus rau hauv cov ntsiav tshuaj sai sai nrog lub raj capillary, kom tag nrho cov ntsiav tshuaj ntub thiab tawg. Cov hmoov txhuv nplej siab thiab nws cov derivatives, thiab cellulose derivatives tag nrho yog cov hom disintegrant.
Hom disintegrant no feem ntau ntxiv ob qho tib si sab hauv thiab sab nraud. Txoj kev sib ntxiv sab nraud yog qhov tsim nyog rau kev tawg sai ntawm cov ntsiav tshuaj mus rau hauv cov khoom, thaum txoj kev sib ntxiv sab hauv yog qhov tsim nyog rau cov khoom tawg yooj yim ntawm cov khoom thiab tuaj yeem txhim kho qhov hardness ntawm tus neeg sawv cev.
Cov nyhuv o
Ntxiv nrog rau qhov kev txiav txim ntawm capillary, qee cov disintegrants lawv tus kheej tuaj yeem swell nrog dej ua rau cov ntsiav tshuaj tawg. Piv txwv li, cov hmoov txhuv nplej siab derivative sodium carboxymethyl hmoov txhuv nplej siab tuaj yeem o hauv dej txias, thiab cov nyhuv o ntawm nws cov granules tseem ceeb heev, ua rau cov ntsiav tshuaj tawg sai heev.
Gas ntau lawm
Disintegrants uas tsim cov roj yog tsuas yog siv rau cov ntsiav tshuaj uas yuav tsum tau disintegrate los yog yaj sai sai, xws li effervescent ntsiav tshuaj, ua npuas ncauj ntsiav tshuaj, thiab lwm yam. Nyob rau hauv lub effervescent disintegrant, citric acid los yog tartaric acid ntxiv rau sodium carbonate los yog sodium bicarbonate feem ntau yog siv. Thaum nws ntsib dej, cov pa roj carbon dioxide tsim tawm, thiab cov ntsiav tshuaj disintegrates nrog kev pab ntawm cov pa nthuav dav.
Enzymatic hydrolysis
Qee cov enzymes muaj kev cuam tshuam rau qee cov tshuaj ntxiv hauv cov ntsiav tshuaj. Thaum lawv tau tsim nyob rau hauv tib lub ntsiav tshuaj, lawv tuaj yeem tawg sai sai hauv kev sib cuag nrog dej. Piv txwv li, thaum cov hmoov txhuv nplej siab slurry yog siv los ua ib daim ntawv khi, amylase tuaj yeem muab ntxiv rau cov granules qhuav, thiab cov ntsiav tshuaj compressed tsim los ntawm txoj kev no tuaj yeem tawg sai sai thaum sib cuag nrog dej. Feem ntau siv cov nplaum thiab lawv cov enzymes sib xws yog cov hmoov txhuv nplej siab thiab amylase, cellulose thiab cellulose, pos hniav thiab hemicellulose, gelatin thiab protease, sucrose thiab invertase, alginates thiab carrageenase, thiab lwm yam.
