Figure 2From: Antitussive effects of the peripherally restricted GABAB receptor agonist lesogaberan in guinea pigs: comparison to baclofen and other GABABreceptor-selective agonistsGABA B receptor agonists have differential effects on respiratory rate in awake guinea pigs. Each bar represents the mean ± sem of 5–15 experiments. An asterisk (*) indicates that the treatment reduced respiratory rate relative to that measured in animals pretreated with vehicle (p < 0.05).Back to article page
