'"`UNIQ--vote-00000073-QINU`"' The long half-life gives smooth, once-daily BP control with low rebound. CYP3A4 substrate; pedal edema is the characteristic, dose-related, non-fluid-overload side effect'"`UNIQ--ref-00000074-QINU`"'. (1) ·
'"`UNIQ--vote-00000391-QINU`"' Minimal CYP metabolism; mostly renally cleared unchanged. Cetirizine is the active racemate; levocetirizine is the active R-enantiomer marketed separately'"`UNIQ--ref-00000392-QINU`"'. (1) ·
'"`UNIQ--vote-0000061E-QINU`"' Less reliably anticholinergic than first-generation H1s; minimal antiemetic effect. Desloratadine (Clarinex) is the active enantiomer-of-metabolite version marketed as a Rx alternative. (1)
