Beschreibung

Biochem./physiol. Wirkung

Remimazolam (CNS 7056) is a benzodiazepine derivative with positive allosteric modulator (PAM) activity toward γ-aminobutyric acid type A (GABAA) receptor (pKi = 7.53/7.50/7.56 against 2.5 nM flunitrazepam for binding human/rat/yucatan micropig brain homogenates; pEC50/Emax = 6.44/375% (α1β2γ2), 6.18/186% (α2β2γ2), 6.04/210% (α3β2γ2), 5.86/289% (α5β2γ2s) by whole cell patch clamp using cells expressing respective rat αβγ complex). Intravenous injection (25 mg/kg rats, 15-30 mg/kg mice) causes fast onset and short duration of sedative action with rapid recovery when compared with midazolam.
