The invention relates to particular substituted heterocycle fused gamma-carbolines, their prodrugs, in free, solid, pharmaceutically acceptable salt and / or substantially pure form as described herein, pharmaceutical compositions thereof, and methods of use in the treatment of diseases involving 5-HT2A receptor, serotonin transporter (SERT) and / or pathways involving dopamine D1 / D2 receptor signaling systems, and / or the treatment of residual symptoms.

The invention relates to methods and compositions for the prevention, treatment, or management of gastrointestinal disorders or symptoms thereof, employing two or more agents or compounds to provide a triple site action on 5-HT3 receptors, 5-HT4 receptors, and at least one of H2 receptors and protons pumps.

The subject invention provides useful and novel 5-HT3 antagonists. The subject invention also provides methods for synthesizing the compounds of invention. The invention also provides methods for the treatment of irritable bowel syndrome and other such conditions.

Methods are provided to treat post-operative nausea and vomiting, as well as emesis generally, with 5-HT3 receptor antagonists. In particular, the invention discloses methods for reducing post-operative nausea and vomiting and other emetic events with palonosetron.

This invention provides methods and pharmaceutical compositions for preventing or treating physical dependence and / or withdrawal associated with narcotic use, in particular by modulating a 5-HT3 receptor. Using a computational genetic approach in mice, a gene conserved between mice and humans was identified as candidate as a modulator of physical dependence to morphine. Administration of compounds that modulate 5-HT3 receptors was found to control withdrawal from morphine in mice and humans.

The invention relates to serotonin 5-HT3 receptor antagonists or inhibitors of serotonin 5-HT3 receptor gene expression for use in the treatment of a lesional vestibular disorder.

Contemplated substituted arylpiperazinyl compounds, and most preferably 18F-Mefway, exhibit desirable in vitro and in vivo binding characteristics to the 5-HT1A receptor. Among other advantageous parameters, contemplated compounds retain high binding affinity, display optimal lipophilicity, and are radiolabeled efficiently with 18F-fluorine in a single step. Still further, contemplated compounds exhibit high target to non-target ratios in receptor-rich regions both in vitro and in vivo, and selected compounds can be effectively and sensitively displaced by serotonin, thus providing a quantitative tool for measuring 5-HT1A receptors and serotonin concentration changes in the living brain.

[Problem] To provide a compound which can be used in the prevention and / or treatment of diseases in which 5-HT2B receptor and 5-HT7 receptor are concerned, particularly in the treatment of irritable bowel syndrome (IBS) and / or prevention of migraine.[Means for Resolution] It was found that an acylguanidine derivative having a tricyclic structure or a pharmaceutically acceptable salt thereof has a strong antagonism to 5-HT2B receptor and 5-HT7 receptor. In addition, the compound of the present invention having antagonism to both of the receptors showed superior pharmacological action in comparison with the case of the single use of an antagonist selective for either one of the receptors. Based on the above, the compound of the present invention is useful in preventing and / or treating diseases in which 5-HT2B receptor and 5-HT7 receptor are concerned, particularly in treating irritable bowel syndrome (IBS) and / or preventing migraine.
