Spiperone hydrochloride (Spiroperidol hydrochloride) is a selectivedopamineD₂receptor(K_ivalues of 0.06 nM, 0.6 nM, 0.08 nM, ~350 nM, ~3500 nM forD₂, D₃, D₄, D₁and D₅receptors, respectively) and5-HT_2A/5-HT_1Areceptor(K_is of 1 nM/49 nM) antagonist. Spiperone hydrochloride is also a selectiveα1B-adrenoceptorantagonist. Spiperone hydrochloride activatescalcium-activatedchloride channel(CaCC). Antipsychotic and anti-inflammatory activities^{[1][2][3][4][5]}.

Spiperone is a potent intracellular Ca²⁺enhancer (EC₅₀=9.3 μM) and stimulates intracellular Ca²⁺through a protein tyrosine kinase-coupled phospholipase C-dependent pathway, which results in increased secretion of Cl^-in Calu-3 and CFBE41o^-cell monolayers^[2].
Spiperone significantly decreases the production of nitric oxide in lipopolysaccharide-stimulated BV-2 microglia cells, primary microglia and primary astrocyte cultures. Spiperone also significantly inhibits nitric oxide production in ATP-stimulated primary microglia cultures. Spiperone markedly decreases the production of TNF-α in BV-2 microglia cells. Spiperone attenuates the expression of inducible nitric oxide synthase and proinflammatory cytokines such as IL-1β and TNF-α at mRNA levels in BV-2 microglia cells^[3].

Spiperone (1.5 mg/kg; intraperitoneal injection; on days 1, 3, 6, 7, and 13-21; C57Bl/6 mice) treatment reduces infiltration of the alveolar interstitium and alveolar ducts with inflammatory cells and prevents the growth of the connective tissue in the parenchyma of Bleomycin lungs^[6].
