    Product Description

    Guvacine is an amino acid found in A. catechu (Betel nut).1 It competitively inhibits GABA uptake (IC50 = 10 μM; Ki = 14 μM) in rat hippocampal brain slices.1,2 In vivo, guvacine, at doses ranging from 50-100 mg/kg, decreases spontaneous activity in mice.1 Administration of guvacine also decreases tail flick reaction time in a rat model of morphine analgesia.3

    WARNING This product is not for human or veterinary use.
