Dictionary > Nassa


Nassa may pertain to the gastropod genus Nassa of the taxonomic family Muricidae, class Gastropoda, phylum Mollusca. Nassa may also pertain to noradrenergic and specific serotonergic antidepressants (NaSSas), which belong to a class of psychiatric drugs. They antagonize the α2-adrenergic receptor and some serotonin receptors (e.g. 5-HT2A and 5-HT2C). Thus, they block α2-adrenergic autoreceptors and heteroceptors, and stimulate adrenergic and serotonergic neurotransmission involved in mood regulation.
