Drugs targeting the 5-HT system
Full Agonists
A serotonin full agonist is a chemical that binds to and activates a serotonin receptor and triggers a response, displaying full efficacy at that receptor.
A few psychedelic drugs are full agonists of the 5-HT2A receptor; among them are 25I-NBOMe and Bromo-DragonFLY.
