1 The 5-HT1A/beta-adrenoceptor ligand (+/-)pindolol has been used in clinical trials to enhance the antidepressant effect of selective serotonin (5-HT) reuptake inhibitors (SSRIs). Pindolol 5-hydroxytryptamine receptor 1A Homo sapiens
2 The accelerating effect of (+/-)pindolol is thought to derive from its blockade of the SSRI-induced, 5-HT1A autoreceptor-mediated inhibition of serotonergic cell firing and 5-HT release. Pindolol 5-hydroxytryptamine receptor 1A Homo sapiens
3 In these regions, enriched in 5-HT1A receptors, (+/-)pindolol antagonized the stimulation of [35S]GTPgammaS binding induced by 5-HT in a concentration-dependent manner. Pindolol 5-hydroxytryptamine receptor 1A Homo sapiens
4 This suggests a higher potency of (+/-)pindolol at somatodendritic 5-HT1A receptors compared to post-synaptic 5-HT1A sites. Pindolol 5-hydroxytryptamine receptor 1A Homo sapiens
