Iloperidone hydrochloride is eliminated slowly, with a mean t 1/2 of 13.5 to 14.0 hours. Coadministration with food did not significantly affect AUC, t max , or C max . These results indicate that the rate of iloperidone's absorption is decreased, but the overall bioavailability is unchanged, when the drug is taken with food. Orthostatic hypotension, dizziness, and somnolence were the most commonly reported adverse events.

Iloperidone hydrochloride displays higher affinity for the dopamine D 3 receptor (K i =7.1 nM) than for the dopamine D 4 receptor (K i =25 nM). Iloperidone displays high affinity for the 5-HT 6 and 5-HT 7 receptors (K i =42.7 and 21.6 nM, respectively), and is found to have higher affinity for the 5-HT 2A (Ki=5.6 nM) than for the 5-HT 2C receptor (K i =42.8 nM).

Iloperidone hydrochloride (HP 873 hydrochloride) 是一种 D2/5-HT2 受体拮抗剂，可作用于精神分裂症的非典型抗精神病药。
