title: Anti-inflammatory and anti-nociceptive activity of disodium glycyrrhetinic acid hemiphthalate.
abstract: The anti-inflammatory and anti-nociceptive effects of disodium glycyrrhetinic acid hemiphthalate (glycyrrhetinic acid 3 beta-O-hemiphthalate sodium) after parenteral administration were determined in several animal models. Disodium glycyrrhetinic acid hemiphthalate (GAP) significantly inhibited the rat paw edema induced by carrageenin (ID50 = 21.37 mg/kg), and mice writhing responses caused by acetic acid (ID50 = 9.12 mg/kg). The potency of disodium glycyrrhetinic acid hemiphthalate was about 13.05 times higher than acetylsalicylic acid in inhibiting rat paw edema and 12.84 times higher in inhibiting abdominal constrictions in mice.
