Sulfonamides muaj qhov zoo ntawm cov kab mob dav dav, cov khoom ruaj khov, tus nqi qis thiab ntau yam kev npaj xaiv los ntawm. Lub hauv paus qauv ntawm sulfonamides yog p-sulfanilamide. Nws tuaj yeem cuam tshuam nrog kev sib txuas ntawm cov kab mob folic acid thiab cuam tshuam rau nws txoj kev loj hlob thiab kev loj hlob, yog li inhibiting feem ntau cov kab mob Gram-zoo thiab qee cov kab mob tsis zoo.

Cov kab mob uas nkag siab zoo rau sulfa muaj xws li: Streptococcus, Pneumococcus, Salmonella, thiab lwm yam, thiab cov kab mob me me yog: Staphylococcus, Escherichia coli, Pasteurella, Shigella, Listeria, qee qhov Actinomyces thiab Treponema hyodysenteriae Kuj nkag siab rau sulfonamides; kuj zoo tiv thaiv qee yam protozoa xws li coccidia. Cov kab mob rhiab heev rau sulfonamides tuaj yeem tsim kev tiv thaiv.

Hauv kev siv tiag tiag, sulfonamides feem ntau siv nrog rau lwm cov tshuaj. Feem ntau ntawm qhov tsis zoo ntawm kev siv cov sulfonamides mus sij hawm ntev yog kev cuam tshuam ntawm cov zis, lub raum tsis zoo thiab txo qis kev noj zaub mov.

Txhawm rau txo nws cov tshuaj lom thiab cov kev mob tshwm sim, thawj zaug, qhov ntau npaum li cas yuav tsum tsim nyog, thiab nws yuav tsum tsis txhob nce lossis txo qis ntawm qhov xav tau. Yog tias qhov ntau npaum li cas, nws yuav ua rau muaj tshuaj lom thiab cov kev mob tshwm sim, thiab yog tias qhov ntau npaum li cas me me, nws yuav tsis tsuas yog tsis muaj cov nyhuv kho, tab sis yuav ua rau cov kab mob pathogenic tuaj yeem tsim cov tshuaj tiv thaiv. Qhov thib ob, siv nrog lwm cov tshuaj, xws li amproline thiab sulfonamide synergists, kom txo tau cov koob tshuaj. Thib peb, yog tias cov mis tso cai, qhov sib npaug ntawm sodium bicarbonate tuaj yeem ntxiv. Plaub, cov kab mob tuaj yeem tsim cov qib sib txawv ntawm kev sib txawv ntawm cov tshuaj sulfa, yog li thaum lawv tiv taus cov tshuaj sulfa, nws tsis tsim nyog hloov mus rau lwm cov tshuaj sulfa. Feem ntau hais lus, thawj koob tshuaj sulfa yuav tsum tau muab faib ua ob npaug, thiab tom qab lub sijhawm mob hnyav, cov tshuaj yuav tsum tau hais kom noj nws li 3-4 hnub ua ntej nws tuaj yeem nres.
