Kev piav qhia
Cephalexin yog ib qho tshuaj tua kab mob cephalosporin uas yog siv los tshuaj xyuas qhov cuam tshuam ntawm kev khi, kev qhia, thiab inhibition ntawm PBP3 nrog rau ntxiv cov penicillin-binding proteins (PBPs) ntawm phab ntsa ntawm tes thaum lub sij hawm cov kab mob mucopeptide synthesis. Cephalexin yog siv los kho cov kab mob uas ua rau mob pob ntseg, ua pa, tso zis, thiab kab mob ntawm daim tawv nqaij. Cov kab mob uas tsis muaj zog tiv thaiv Cephalexin tuaj yeem suav nrog Streptococcus pneumonia, Staphylococcus aureus, E. coli, thiab Haemophilus influenza. Cephalexin tseem hu ua Keflex (hom npe), thiab nws tsis txo cov kab mob xws li mob khaub thuas lossis mob khaub thuas.
Mechanism ntawm Action
Cov txheej txheem ntawm kev txiav txim ntawm Cephalexin zoo ib yam li penicillin qhov twg nws inhibits synthesis ntawm cov kab mob ntawm cov phab ntsa, nws tsis muaj feem cuam tshuam rau kev tuag vim yog cov kab mob lysis. Cell lysis yog txuas ntxiv kho los ntawm autolytic enzymes tshwj xeeb rau cov kab mob ntawm phab ntsa, uas suav nrog autolysis. Kev tshawb fawb qhia tias muaj qhov tshwm sim uas Cephalexin cuam tshuam kev ua haujlwm ntawm autolysin inhibitor.
Kev siv cov khoom
Cephalexin yog siv los txo qis kev loj hlob ntawm cov kab mob uas tiv taus tshuaj. Txhawm rau tswj hwm qhov ua tau zoo ntawm Cephalexin, cov tshuaj yuav tsum tau muab tshuaj raws li kev kho mob rau cov kab mob uas tuaj yeem ua rau cov kab mob. Kev muaj cov ntaub ntawv raug thiab kab lis kev cai yuav tsum tau muab tso rau hauv kev txiav txim siab thaum hloov kho cov kab mob tua kab mob. Qhov tsis muaj cov ntaub ntawv no yuav raug txhawb nqa los ntawm kev raug mob thiab cov qauv kev sib kis los cuam tshuam rau kev lees paub txog kev kho mob.
Qee zaum, Cephalexin yog siv rau kev kho mob ntawm cov neeg mob uas ua xua rau penicillin thiab tej zaum yuav muaj lub plawv mob thaum lub sijhawm lawv tab tom ua cov txheej txheem ntawm lawv txoj kev ua pa, txhawm rau tiv thaiv kev kis kab mob ntawm lawv lub plawv li qub.
