Background:
Cyclizine is a histamine H1receptor antagonist.1,2,3It binds selectively to histamine H1receptors (Kd= 5 nM) over H2and H3receptors (Kds = 1,600 and >580 nM, respectively).3Cyclizine inhibits anti-IgE-induced histamine release from isolated human lung fragments with an IC50value of 5.42 ?M but induces histamine release with a 50% release concentration (RC50) of 10.81 ?M.4It reduces LPS-induced nitrite accumulation and protein levels of induced nitric oxide synthase (iNOS) in RAW 264.7 cells when used at a concentration of 100 nM.2Cyclizine (10 and 20 mg/kg) reduces immobility in the forced swim test in rats.5
