Ligands of various chemical classes (e.g., indoles, indazoles, benzamides, carbazoles, and quinolines) have demonstrated high affinity for the 5-HT3 receptor in radiolabeled ligand-binding studies, and have shown 5-HT3 receptor antagonistic activity in functional assays which utilize the excitatory effects of 5-HT on enteric neurons and autonomic afferents.

The most important neurotransmitters in CINV are serotonin, dopamine, and substance P, which bind to 5HT3, dopamine-2, and NK-1 receptors, respectively.19,20 Another way of emesis activation may be the direct stimulation of CTZ by metabolites of chemotherapy or intestinal peptides circulating in the blood.

These drugs selectively and competitively bind to 5-HT3 receptors, blocking serotonin binding at vagal afferents in the gut and in the regions of the central nervous system involved in emesis, including the chemoreceptor trigger zone and the nucleus tractus solitarii [28,29].

Oral tramadol has been shown to have the same analgesic efficacy as oral diclofenac for post-tonsillectomy pain in patients 11 years and older, without the side effects of NSAIDs.29 It is important to note that the use of ondansetron to treat PONV results in the inhibition of tramadol analgesia probably due to a reduction of binding to the 5-HT3 receptors at the spinal level.30 Tramadol is currently available in a tablet form alone or in combination with acetaminophen in the USA.
5-HT3 Binding (binding) of in spinal associated with pain, tramadol, paracetamol, analgesic, analgesia, post-operative nausea, cinod and diclofenac

In view of the 5-HT releasing effects of selective 5-HT3 receptor agonists to which metformin (N-N-dimethylbiguanide) is structurally related, we investigated whether metformin directly interacts with 5-HT3 receptors.

However, the recent discovery of additional 5-HT3 subunits and the dawning realization that central and peripheral 5-HT3 receptor populations might comprise several subtypes characterized by distinct functional properties has emphasized the complexity of human 5-HT3 receptor signaling.

Palonosetron has proven to be an excellent addition to the armamentarium against CINV, specifically against delayed and overall CINV, which until now has proved difficult to treat with conventional 5-HT3 RAs.

Because local anesthetics have different clinical properties, we have tested the hypothesis that differences in interactions at the 5-HT3 receptor may be clinically relevant by investigating the effects of 4 local anesthetics on recombinant wild-type and 4 mutant 5-HT3A receptors.
