Pimethixene maleate is a potent antihistamine and antiserotonergic compound used as an antimigraine agent. It exhibits strong antagonistic activity at multiple receptors, including serotonin 5-HT1A (pKi 7.63), 5-HT2A (pKi 10.22), 5-HT2B (pKi 10.44), 5-HT2C (pKi 8.42), histamine H1 (pKi 10.14), dopamine D2 (pKi 8.19), dopamine D4.4 (pKi 7.54), muscarinic M1 (pKi 8.61), and muscarinic M2 (pKi 9.38) receptors. Its broad receptor-binding profile contributes to its therapeutic efficacy in migraine management.
