FLEZELASTINE, a phthalazinone derivative, an anti-asthmatic/anti-allergic agent. It exhibits inhibition of histamine release and 5-lipoxygenase, calcium antagonistic properties and antagonism at the histamine H1 receptor. FLEZELASTINE is a racemate consisting of (+)- and (-)-enantiomers. Both enantiomers contribute to the pharmacodynamic efficacy of racemic flezelastine.
