Nyob rau hauv daim teb ntawm cov kws tshuaj, ntau cov tshuaj siv tau zoo heev yog qhov nyuaj rau tib neeg lub cev vim lawv insolubility hauv dej. Txij ntawm no, muaj qhov tsis zoo hu ua "HydroxyPropyl Beta {}} dextrin (hp}} cd)" ua si lub luag haujlwm tseem ceeb. Nws yog zoo li cov tshuaj ntsiav heev "molecular capsule", ntsiag to hloov cov hmoo ntawm cov tshuaj tsis txheeb.
CyclodExtrin nws tus kheej yog cov qauv ua qauv los ntawm kev sib txuas ntawm cov piam thaj molecules xaus. HydroxyPropyl Beta - Cyclodextrin yog ib qho khoom siv tshuaj hloov kho tshiab los ntawm kev qhia txog hydroxyproproyl ntawm lub hauv paus. Qhov kev hloov kho no coj cov ntsiab lus tseem ceeb: nws khaws cov hydrophobic (lipophilic) kab noj hniav sab hauv tus thawj cyclodextrin, thaum ua rau sab nrauv ntau hydrophilic. Xib fwb Chen Ming, ib tug tswv cuab ntawm National Medical Medicial Commissionia, thaum lub Plawv Tsis Muaj Cov Hluav Taws Xob Cov pob no tau txhim kho rau solubility thiab ruaj khov ntawm cov tshuaj tsis zoo (xws li qee cov tshuaj tiv thaiv kab mob, tshuaj tiv thaiv kab mob, thiab tshuaj mormatural) hauv cov dej.
Piv nrog ntxov cyclodextrins (xws li - cyclodextrin), hp - - Cd tau lees paub Biocompatibility zoo dua thiab txo qis raum toxicity. Qhov no tseem yog qhov tseem ceeb vim li cas nws tuaj yeem siv dav hauv lub siab- kev txhaj tshuaj tiv thaiv xws li kev txhaj tshuaj. Ob qho Medicget Minister and Dra) thiab European Pharpacopoia (pH. EUR.) Tau suav nrog qhov kev tswj hwm thiab nruj me ntsis thiab kev nyab xeeb hauv ntau yam kev npaj. Cov ntaub ntawv tshawb fawb qhia tau tias thaum siv nyob rau hauv kev pom zoo ntau npaum li cas, nws muaj kev nyab xeeb yog qhov zoo.
Cov kws tshaj lij qhia tias nrog kev txhim kho txuas ntxiv ntawm cov khoom siv tshuaj ntsuab uas muaj kev nyab xeeb thiab kev txhim kho cov qhov rooj kev ua tau zoo dua qub, thiab nws yog tus yuam sij qhib cov qhov rooj mus rau cov ntawv thov kev kho mob ntawm ntau qhov kev thov tshuaj.
