레보세티리진이염산염

용도Levocetirizine dihydrochloride has been used as standard in the thin layer chromatography optimization and in preparation of racemic cetirizine standard for subcritical fluid chromatography-tandem mass spectrometry analysis.

일반 설명Levocetirizine dihydrochloride,(R)-[2-[4-[(4-chlorophenyl) phenylmethyl]-1-piperazinyl] ethoxy] acetic acid dihydrochloride, (Xyzal) is awhite, crystalline powder and is water soluble. ThisR-enantiomer is has a 30-fold higher affinity than the S-enantiomer,and dissociates more slowly from H1-receptors.Pharmacologically, it displays the same receptor and CNSselecitivity profile as the racemate, cetirizine,and thus the same therapeutic advantages. Levocetirizine isindicated for the relief of symptoms associated with allergicrhinitis (seasonal and perennial) in adults and children 6 yearsof age and older and for the treatment of the uncomplicatedskin manifestations of chronic idiopathic urticaria in adultsand children 6 years of age and older. Its pharmacokineticsand clearance profile are essentially the same as the racemate,cetirizine .
