Txhawm rau kom tshem tawm cov ntshav qab zib thiab nws cov tsos mob, cov tshuaj tshwj xeeb tau siv uas tau txhawm rau txhawm rau txo qis qis cov ntshav qab zib hauv cov ntshav ntawm tus neeg mob. Cov kab mob antidiabetic (hypoglycemic) yuav yog rau kev siv niam txiv, nrog rau lub qhov ncauj.
Cov tshuaj hypoglycemic qhov ncauj hypoglycemic feem ntau tau muab cais raws li nram no:
- sulfonylurea derivatives (cov no yog Glibenclamide, Glikvidon, Gliklazid, Glimepirid, Glipizid, Chlorpropamide);
- alpha glucosidase inhibitors ("Acarbose", "Miglitol");
- meglitinides ("Nateglinide", "Repaglinide");
- cov lag luam loj ("Metformin", "Buformin", "Fenformin");
- thiazolidinediones (Pioglitazone, Rosiglitazon, Tsiglitazon, Englitazon, Troglitazon);
- ncetinomimetics.
Cov yam ntxwv thiab kev ua ntawm sulfonylurea derivatives
Cov khoom siv ntawm sulfonylureas tau pom los ntawm kev sib tsoo heev nyob rau hauv nruab nrab ntawm lub xyoo pua xeem. Lub peev xwm ntawm cov tebchaw tau tsim nyob rau lub sijhawm thaum nws muab tawm tias cov neeg mob uas tau siv tshuaj sulfa kom tshem tawm cov mob sib kis tseem tau txais txo qis hauv lawv cov piam thaj hauv ntshav.

Cov tshuaj yog qhov tshwj xeeb tshaj tawm tiv thaiv keeb kwm ntawm cov hnyav dhau los thiab ua tsis tau zoo ntawm kev noj haus lossis tsis muaj txiaj ntsig ntawm sulfonylurea npaj. Kev nqis tes ntawm biguanides tsis tau pom tias tsis muaj cov tshuaj insulin hauv cov ntshav.
Alpha glucose inhibitors inhibit qhov tawg ntawm polysaccharides thiab oligosaccharides. Qhov nqus thiab tsim cov piam thaj txo thiab yog li muaj kev ceeb toom ntawm kev txhim kho ntawm postprandial hyperglycemia. Tag nrho cov carbohydrates uas tau noj nrog zaub mov, hauv lawv lub xeev tsis hloov, nkag mus hauv ntu qis hauv txoj hnyuv thiab qhov loj. Qhov nqus ntawm monosaccharides kav ntev txog 4 teev.
Tsis zoo li cov tshuaj sulfa, alpha glucose inhibitors tsis nce insulin tso tawm thiab tsis tuaj yeem ua rau mob ntshav qab zib tsawg.
Raws li kev tshawb pom, nws tau ua pov thawj tias kev kho nrog kev pab ntawm "Acarbose" tej zaum yuav nrog kev txo qis hauv txoj kev loj hlob ntawm txoj kev hnyav ntawm atherosclerosis.
Kev siv cov tshuaj tiv thaiv kab mob no tuaj yeem ua hom kev kho mob monotherapy, thiab tseem txuas lawv nrog lwm cov tshuaj noj hauv qhov ncauj uas txo cov ntshav qab zib. Qhov muab tshuaj thawj zaug feem ntau yog 25 txog 50 mg tam sim ua ntej lossis thaum noj mov. Nrog rau kev kho mob tom qab, qhov ntau npaum no tuaj yeem raug nce mus txog qhov siab tshaj plaws (tab sis tsis ntau tshaj 600 mg).
Cov cim tseem ceeb rau kev teem caij alpha-glucosidase inhibitors yog: hom 2 mob ntshav qab zib mellitus nrog kev noj zaub mov tsis zoo, hom 1 mob ntshav qab zib mellitus, tab sis yuav muaj kev sib txuam nrog kev kho mob.
