Abstract

The pain is an universal experience, and frequently follows anxiety and depression cases. Some specific drugs used in depression and anxiety treatment are also used for the relief of pain. There are evidences showing that exposure to threatening situations can result in pain inhibition. In this way, studies involving pain and anxiety use animal models as tools for potential therapeutic agents screening as well as for enhance the knowledge about the neurobiology of emotions. This study investigated the following effects: acute and chronic fluoxetine treatment; microinjections of 5-HT1A and 5HT2C receptors agonists intra-periaqueductal gray matter (PAG), and the administration combined of these drugs on antinociception induced by the open arms (OAA) of the elevated plus maze (EPM). Furthermore, we investigated the effects of fluoxetine chronic treatment on serotonin, 5-HIAA, 5-HT1A and 5HT2C receptors levels within PAG. (AU)
