Effect of treatment with Scutellaria baicalensis extract on delayed gastric emptying induced by ritonavir in rats. When compared with normal gastric emptying, ritonavir (20 mg kg−1) significantly reduced gastric emptying (P < 0.001). Administering S. baicalensis extract to ritonavir-treated rats attenuated the delayed gastric emptying significantly in a dose-dependent manner, suggesting that the extract reduces gastrointestinal dysfunction induced by ritonavir (P < 0.05; n = 5–8). Veh, vehicle; Rit, ritonavir; SbE, S. baicalensis extract; SbE low dose, 0.7 mg kg−1; SbE high dose, 2 mg kg−1. *Significantly different compared with control; #significantly different compared with the Rit + Veh group.
