Pheej Yig Tswj Kev Tso Tshuaj Xa Khoom Siv

Kab lus no tshawb txog cov toj roob hauv pes uas pheej yig thiab siv tau zoo pheej yig tswj tso tshuaj xa tshuab. Peb mam li tshuaj xyuas ntau yam thev naus laus zis, lawv qhov zoo thiab qhov tsis zoo, thiab cov yam ntxwv cuam tshuam rau kev siv nyiaj. Kawm paub txog ntau txoj hauv kev kom ua tiav cov tshuaj tso tawm thiab tshawb pom cov kev xaiv twg zoo tshaj plaws rau cov kev xav tau kho mob tshwj xeeb. Cov lus qhia dav dav no yuav pab koj taug qab qhov nyuaj ntawm thaj chaw tseem ceeb hauv kev txhim kho tshuaj.

Nkag siab Kev Tswj Tso Tawm Technology

Pheej yig tswj kev tso tshuaj xa muab cov txiaj ntsig tseem ceeb tshaj li kev tswj hwm tshuaj. Los ntawm kev tswj hwm tus nqi ntawm cov tshuaj tso tawm, cov tshuab no tuaj yeem txhim kho kev kho mob, txo cov kev mob tshwm sim, thiab txhim kho kev ua raws li tus neeg mob. Qhov no yog ua tiav los ntawm ntau yam mechanisms, txhua tus nrog nws tus nqi cuam tshuam.

Mechanisms ntawm Tswj Tso Tawm

Ob peb lub tswv yim pab tswj cov tshuaj tso tawm. Cov no suav nrog:

• Matrix systems: Cov tshuaj yog dispersed nyob rau hauv ib tug polymeric matrix uas tswj nws tso tawm tus nqi. Tus nqi-kev ua tau zoo ntawm txoj hauv kev no yog nyob ntawm qhov kev xaiv ntawm polymer.
• Reservoir systems: Cov tshuaj yog encapsulated nyob rau hauv lub reservoir, thiab nws tso tawm yog tswj los ntawm tus nqi-tswj daim nyias nyias. Txoj kev no tuaj yeem muab kev tswj xyuas meej tab sis tej zaum yuav kim dua li matrix systems.
• Erosion systems: Kev xa khoom maj mam erodes, tso cov tshuaj ntawm tus nqi tswj. Tus nqi yaig yog txiav txim los ntawm cov khoom ntawm cov khoom siv system.
• Osmotic systems: Cov tshuab no siv osmotic siab los tsav cov tshuaj tso tawm. Lawv feem ntau muab cov ntawv tso tawm tsis tu ncua tab sis tuaj yeem ua haujlwm nyuaj rau kev tsim khoom.

Cov yam ntxwv cuam tshuam rau tus nqi ntawm Cov Txheej Txheem Tshaj Tawm

Tus nqi ntawm ib pheej yig tswj tso tshuaj xa system nyob ntawm ntau yam. Cov no suav nrog:

Cov nqi khoom siv

Kev xaiv cov ntaub ntawv cuam tshuam rau tag nrho cov nqi. Biodegradable polymers, thaum muab cov txiaj ntsig zoo xws li txo qis kev cuam tshuam, tuaj yeem kim dua li lwm yam uas tsis yog biodegradable. Kev xaiv cov khoom tsim nyog, raug nqi zoo yog qhov tseem ceeb rau kev tsim cov tshuab kev lag luam.

Manufacturing Complexity

Cov txheej txheem tsim khoom nyuaj, xws li cov uas xav tau rau microspheres lossis nanoparticles, tuaj yeem nce nqi ntau lawm. Cov txheej txheem yooj yim xws li cov ntsiav tshuaj yooj yim nrog cov txheej txheem tso tawm tuaj yeem muab cov txiaj ntsig zoo dua.

Scale of Production

Tus nqi ntawm ib chav tsev feem ntau txo qis nrog kev nce qib ntau lawm. Kev tsim khoom loj tuaj yeem tau txais txiaj ntsig los ntawm kev lag luam ntawm cov nplai, muaj peev xwm ua tau pheej yig tswj tso tshuaj xa siv tau ntau dua.

Piv txwv ntawm Cheap Controlled Release Drug Delivery Systems

Ntau yam piv txwv qhia txog ntau yam uas muaj pheej yig tswj tso tshuaj xa technologies:

Oral Controlled-Release Tablets

Ntau cov tshuaj muaj nyob hauv khw muag khoom siv cov tshuaj tswj-tso tawm, feem ntau siv cov polymers pheej yig thiab cov txheej txheem tsim khoom kom tau txais txiaj ntsig zoo. Cov no yog dav siv rau cov mob ntev uas yuav tsum tau muaj cov tshuaj zoo ib yam.

Transdermal Patches

Txawm hais tias feem ntau nyuaj dua li lub qhov ncauj, cov tshuaj tiv thaiv kab mob ua rau muaj txiaj ntsig zoo rau kev xa tshuaj mus ntev. Kev tsim kho tshiab hauv cov nplaum nplaum thiab cov tshuab membrane yog tsav kev rau siab rau cov kev xaiv zoo.

Yav tom ntej Trends nyob rau hauv pheej yig tswj kev tso tshuaj xa

Kev tshawb fawb niaj hnub thawb cov ciam teb ntawm kev tswj cov tshuaj xa. Txoj kev loj hlob ntawm cov khoom siv biomaterials tshiab, cov txheej txheem tsim khoom siab heev, thiab cov qauv tshuaj tshiab yuav tsum tau ua kom txo qis tus nqi ntawm cov tshuab no, ua rau lawv nkag tau mus rau cov pej xeem dav.

Rau kev tshawb fawb ntxiv thiab cov kev xaiv kho mob tshwj xeeb, koj tuaj yeem xav sab laj cov peev txheej xws li Shandong Baofa Cancer Research Institute.

Kev lees paub: Kab lus no muab cov lus qhia dav dav thiab yuav tsum tsis txhob suav hais tias yog cov lus qhia kho mob. Tham nrog tus kws kho mob rau txhua yam kev txhawj xeeb txog kev noj qab haus huv lossis ua ntej txiav txim siab txog koj txoj kev noj qab haus huv lossis kev kho mob.
