Background

Cyclizine is a histamine H₁ receptor antagonist.^1,2,3 It binds selectively to histamine H₁ receptors (K_d = 5 nM) over H₂ and H₃ receptors (K_ds = 1,600 and >580 nM, respectively).³ Cyclizine inhibits anti-IgE-induced histamine release from isolated human lung fragments with an IC₅₀ value of 5.42 µM but induces histamine release with a 50% release concentration (RC₅₀) of 10.81 µM.⁴ It 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.² Cyclizine (10 and 20 mg/kg) reduces immobility in the forced swim test in rats.⁵
