Elzasonan (CP-448,187) is a selective 5-HT_1B and 5-HT_1D receptor antagonist that was under development by Pfizer for the treatment of depression but was discontinued, possibly due to poor efficacy. By preferentially blocking 5-HT_1B and 5-HT_1D autoreceptors, elzasonan is thought to enhance serotonergic innervations originating from the raphe nucleus, thereby improving signaling to limbic regions like the hippocampus and prefrontal cortex and ultimately resulting in antidepressant effects.
