Yuav ua li cas kom ua tiav cov nyhuv tso tawm ntawm cov tshuaj
Muaj ob lub ntsiab ntawm kev txhawb nqa-tso thev naus laus zis rau cov ntsiav tshuaj ntawm qhov ncauj, ib qho yog membrane sustained tso tawm, thiab lwm yam yog matrix sustained tso tawm membrane sustained tso tawm, uas yog sib npaug rau lub tsev kaw cov tshuaj, tsuas yog ib lub qhov rooj me me cia. lawv tawm maj mam. Qhov kev tso tawm tsis tu ncua ntawm cov matrix yog sib npaug ntawm cov tshuaj entanglement nrog lub pob ntawm cov nroj tsuag hauv dej kom lawv tsuas tuaj yeem tso tawm maj mam. Muaj ntau yam txuj ci tshwj xeeb. Qee cov ntaub ntawv polymer tsis soluble yuav raug siv rau kev tso tawm ntawm daim nyias nyias. Lub moj khaum cov ntaub ntawv tuaj yeem yog insoluble, hydrophilic gels lossis bioerodible cov ntaub ntawv. Membrane cov ntaub ntawv tuaj yeem tso cov tshuaj los ntawm kev kho cov khoom xyaw kom tsim tau qee qhov micropores, lossis laser drilling thiab lwm txoj hauv kev. Tsis tas li ntawd, cov tshuaj pellets tuaj yeem qhwv nrog cov khoom tso tawm kom ua tiav cov nyhuv tso tawm, uas tuaj yeem ua ke ntawm cov txheej txheem sib txawv, lossis ntau txheej txheej. Sustained-release capsules siv txoj cai no. Cov pellets sab hauv muaj cov txheej txheem sib txawv, thiab lub sijhawm rau yaj cov tshuaj kuj txawv. Tom qab ntawd, kev sib xyaw ua ke ntawm ntau cov pellets nrog cov tshuaj sib txawv tso tawm nrawm yuav tso tawm ntau dua li tag nrho.
yooj yim muab:
Ntawd yog, cov tshuaj yuav tsis tso tawm tag nrho hauv lub cev tam sim ntawd.
Nws txo cov teeb meem ntawm kev noj tshuaj thiab ua kom cov ntshav siab ruaj khov, uas tuaj yeem txo cov kev mob tshwm sim ntawm cov tshuaj.
