Hauv kev kho mob pharmacology, thawj xaj kinetics raug suav hais tias yog kab tawm txheej txheem », vim hais tias tus nqi ntawm kev tshem tawm yog proportional rau cov tshuaj concentration. Qhov no txhais tau hais tias qhov siab dua cov tshuaj concentration, nws qhov kev tshem tawm ntau dua.

Hais txog qhov no, qhov txawv ntawm thawj qhov kev txiav txim thiab xoom xaj kinetics yog dab tsi?

Qhov tseem ceeb qhov sib txawv ntawm xoom thiab ua ntej - xaj kinetics yog lawv tshem tawm tus nqi piv rau tag nrho cov ntshav plasma concentration. Zero - xaj kinetics Kev tshem tawm tas li tsis hais txog ntawm cov ntshav plasma concentration, tom qab ib theem tshem tawm raws li qhov system ua kom txaus.

Tsis tas li ntawd, yog thawj qhov kev txiav txim kinetics nyob ntawm qhov concentration? Thawj qhov kev txiav txim tshem tawm kinetics : ib qhov ratio (eg. Thawj qhov kev txiav txim kinetics yog a concentration - nyob txheej txheem (piv txwv li qhov siab dua concentration , qhov nrawm dua qhov clearance), whereas zero xaj tshem tawm tus nqi yog ywj siab ntawm concentration.

Ib sab saum toj no, thawj qhov kev txiav txim kinetics txhais li cas?

Thawj qhov kev txiav txim kinetics tshwm sim thaum ib qho kev faib ua feem ntawm cov tshuaj raug tshem tawm ib lub sijhawm. Tus nqi ntawm kev tshem tawm yog proportional rau tus nqi ntawm cov tshuaj nyob rau hauv lub cev. Qhov siab dua qhov concentration, qhov ntau dua cov tshuaj tshem tawm ib lub sijhawm.

Qhov kev txiav txim xoom yog dab tsi?

Kev txhais ntawm xoom - xaj tshuaj tiv thaiv : ib chemical tshuaj tiv thaiv uas tus nqi ntawm tshuaj tiv thaiv yog tas li thiab ywj siab ntawm cov concentration ntawm cov tshuaj reacting - piv xaj ntawm a tshuaj tiv thaiv.
