Dab tsi yog qhov txawv ntawm cetirizine hydrochloride thiab Levocetirizine dihydrochloride?
Muaj qhov sib txawv ntawm cov qauv molecular thiab kev ua tau zoo ntawmLevocetirizine dihydrochloridethiab cetirizine hydrochloride.
1, Txawv molecular qauv:Cetirizine dihydrochloride yog ib daim ntawv racemic uas muaj ob sab laug-tes qauv thiab sab tes xis qauv; Cov khoom xyaw ntawm Levocetirizine dihydrochloride tsuas muaj cov qauv sab laug xwb. Cov txiaj ntsig tau pom tau tias cov qauv sab laug yog cov khoom muaj txiaj ntsig zoo ntawm cetirizine, nrog rau kev xaiv siab rau H1 receptors uas yog 30 npaug ntawm cetirizine. Nyob rau tib lub sijhawm, cov khoom no tsis muaj qhov tseem ceeb anticholinergic lossis los tiv thaiv serotonin, thiab nws cov nyhuv inhibitory hauv nruab nrab yog me me. Txawm li cas los xij, nws tuaj yeem cuam tshuam qhov sib txuam ntawm eosinophils. Tsim nyog siv cov khoom no yog txoj hauv kev kom tau txais txiaj ntsig zoo, xaiv, thiab kev sib tw peripheral H1 receptor antagonists.
2, Txawv pharmacological teebmeem:Raws li cov ntaub ntawv kev sim cuam tshuam, qhov kev sib khi muaj peev xwm ntawm levocetirizine hydrochloride rau tib neeg H1 histamine receptor yog 30 npaug ntawmCetirizine hydrochloride. Yog li ntawd, nyob rau tib koob tshuaj,Levocetirizine dihydrochloride USPmuaj cov nyhuv antihistamine muaj zog dua li Cetirizine dihydrochloride, thiab ua rau muaj kev phiv tshuaj txo qis. Tsis tas li ntawd, kev faib tawm thiab kev tswj hwm ntawm ob cov tshuaj no kuj txawv. Txawm li cas los xij, tsis hais txog qhov sib txawv ntawm lawv, nws yuav tsum sab laj nrog koj tus kws kho mob ua ntej thaum lub sijhawm tshawb fawb lossis kev siv theem.
Peb lub tuam txhab tuaj yeem muab Levocetirizine dihydrochloride, cetirizine hydrochloride, loratadine, ebastine, Mizolastine,Fexofenadinethiab lwm yam. ntawm tus nqi qis. Yog tias koj txaus siab, thov sau ntawv los ntawmemail:sales6@faithfulbio.com
