Opiates are widely used analgesics in anesthesiology, but they have serious adverse effects such as depression of breathing. This is caused by direct inhibition of rhythm-generating respiratory neurons in the Pre-Boetzinger complex (PBC) of the brainstem. We report that serotonin 4(a) [5-HT4(a)] receptors are strongly expressed in respiratory PBCneurons and that their selective activation protects spontaneous respiratory activity. Treatment of rats with a 5-HT4 receptor–specific agonist… Expand
