Perlapine (AW-14233;HF-2333;Hypnodine) is a potent antihistamine that has high affinity for dopamine D1, α1, α2 and 5-HT2A receptors.

Cannabigerol is a high affinity α±2-adrenergic receptor agonist, moderate affinity 5-HT1A receptor antagonist, and low affinity CB1 receptor antagonist ; also binds to the CB2 receptor; it can relieve interocular pressure, which may be of benefit in the treatment of glaucoma.

Ritanserin is a highly effective, relatively selective, long-acting antagonist of 5-HT2 receptor (IC50: 0.9 nM), less active on Histamine H1, Dopamine D2, Adrenergic α1, Adrenergic α2 receptors.
