The Second-Generation Antipsychotic Perospirone Inhibits Voltage-Gated K+ Channels in Coronary Arterial Smooth Muscle Cells. (PubMed, J Appl Toxicol) - "These findings demonstrate that perospirone inhibits vascular Kv1.5 subtype channels in a concentration-dependent but use-independent manner. This previously unrecognized off-target effect suggests that perospirone can affect vascular function, highlighting its potential cardiovascular implications in clinical settings."

Delirium due to Trousseau syndrome treated with memantine and perospirone: A case report. (PubMed, PCN Rep) - "Although haloperidol, risperidone, and chlorpromazine were used, severe insomnia persisted. We report the first case of Trousseau syndrome delirium treated by memantine used with perospirone. Although further studies are needed, memantine and perospirone might be candidates for the management of psychiatric symptoms associated with Trousseau syndrome."

The effective perospirone augmentation with clonazepam for treatment-resistant burning mouth syndrome: A case report. (PubMed, Neuropsychopharmacol Rep) - "Further attempts to alleviate symptoms by combining aripiprazole with amitriptyline, aripiprazole with mirtazapine, or aripiprazole with clonazepam were limited; however, nearly all symptoms were relieved by a combination of perospirone 8.0 mg with clonazepam 1.5 mg. However, a regimen of perospirone 6.0 mg and clonazepam 1.5 mg relieved the crumb-like sensation and pain and culminated in a stabilized condition. The reported cases suggested that multiple approaches targeting the dopaminergic circuit in basal ganglia involving the serotoninergic and GABA systems, through the administration of perospirone with clonazepam is an effective adjunctive treatment for the remaining uncomfortable sensations in patients with BMS."

Adverse effects of antipsychotics on sleep in patients with schizophrenia. Systematic review and meta-analysis. (PubMed, Front Psychiatry) - "Several of the included antipsychotics were associated with a significantly increased risk of somnolence; haloperidol (OR, 1.90; 95% CrI, 1.12-3.22), lurasidone (OR, 2.25; 95% CrI, 1.28-3.97) and ziprasidone (OR, 1.79; 95% CrI, 1.06-3.02) had the narrowest confidence intervals...The evidence shows that chlorpromazine, clozapine, flupentixol, perospirone, and amisulpride had favorable safety profiles. In contrast, ziprasidone, perphenazine, haloperidol, and risperidone were the least safe for sleep. https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42017078052, identifier: PROSPERO 2017 CRD42017078052."

Exploration of interaction interface of TRKβ/BDNF through fingerprint analysis to disinter potential agonists. (PubMed, Mol Divers) - "The study revealed molecular interactions of Perospirone, Droperidol, Urapidil, and Clobenzorex with the crucial amino acids lining the active binding pocket of TRKβ...Clobenzorex displayed high stability in dynamics simulation and therefore this drug is recommended for further experimental evaluations to attain better mechanistic insights and predict its implications in correcting neuropathological aberrations. This study's focus on the interaction interface between TRKβ and BDNF, combined with the utilization of fingerprint analysis for drug repurposing, contributes to our understanding of neurotrophic signalling and holds potential for identifying new therapeutic options for neurological disorders."

Agonistic properties of a series of psychotropic drugs at 5-HT receptors in rat and human brain membranes determined by [S]GTPγS binding assay. (PubMed, Pharmacol Rep) - "Our previous studies have raised the concept of a psychoactive drug group with a common pharmacological mechanism of action, i.e., 5-HT receptor agonism, consisting of perospirone, aripiprazole, ziprasidone, clozapine, quetiapine, nemonapride, and trazodone. The present study demonstrates the data indicating that brexpiprazole and probably vortioxetine are included in this drug group. Lurasidone and asenapine are excluded from this group."

Safety and Effectiveness of Perospirone in Comparison to Risperidone for Treatment of Delirium in Patients with Advanced Cancer: A Multicenter Prospective Observational Study in Real-World Psycho-Oncology Settings.

Low-dose perospirone was thus found to be effective for the treatment of delirium in patients with advanced cancer and may be associated with fewer episodes of over-sedation as an adverse event."

Inhibitory Effects of Antipsychotics on the Contractile Response to Acetylcholine in Rat Urinary Bladder Smooth Muscles. (PubMed, Biol Pharm Bull) - "Further, 11 antipsychotics (perphenazine, fluphenazine, prochlorperazine (phenothiazines), haloperidol, bromperidol, timiperone, spiperone (butyrophenones), pimozide (a diphenylbutylpiperidine), perospirone, blonanserin (serotonin-dopamine antagonists; SDAs), and asenapine (a MARTA)) significantly suppressed ACh-induced contraction; however, suppression occurred at concentrations substantially exceeding clinically achievable blood levels. The remaining nine antipsychotics (pipamperone (a butyrophenone), sulpiride, sultopride, tiapride, nemonapride (benzamides), risperidone, paliperidone (SDAs), aripiprazole, and brexpiprazole (dopamine partial agonists)) did not inhibit ACh-induced contractions at concentrations up to 10 M. These findings suggest that chlorpromazine, levomepromazine, zotepine, olanzapine, quetiapine, and clozapine should be avoided by elderly people with urinary disorders."

[VIRTUAL] Camptocormia Secondary to Dopamine-Antagonist-Induced Dystonia of the Rectus Abdominis Muscles: A Case Report (CINP 2021) - "She was referred to our hospital at the age of 51 with mild-asymptomatic scoliosis which gradually developed after starting risperidone, and mild delusions and auditory hallucination with risperidone 2 mg/d, perospirone 12 mg/d, and sodium valproate 400 mg/d. Camptocormia resolved by reducing the dose of perospirone and adding quetiapine. This suggests that lowering the intensity of dopamine D2 receptor blockade of dopamine antagonist improved the dystonia of the rectus abdominis muscles and thereby camptocormia. Thus, in a case of camptocormia, abdominal physical examination and abdominal CT scan may be highly advisable considering the possibility of truncal dystonia."

Neuroprotective effects of the second generation antipsychotics. (PubMed, Schizophr Res) - "A review of the literature suggests that in addition to their antipsychotic efficacy and low motoric side effects, SGAs exert measurable neuroprotective effects mediated via multiple molecular mechanisms and often in a dose-dependent manner. The neuroprotective effects of SGAs range from preventative to restorative and may play a salutary role in ameliorating the neurodegenerative effects of psychosis."

Antihyperalgesic effects of intrathecal perospirone in a rat model of neuropathic pain.

We conclude that perospirone attenuates mechanical and cold hyperalgesia principally via 5-HT receptor activation in the spinal cord, and the agent is a promising novel candidate for neuropathic pain relief."

Experimental analysis of the onset mechanism of TdP reported in an LQT3 patient during pharmacological treatment with serotonin-dopamine antagonists against insomnia and nocturnal delirium. (PubMed, Heart Vessels) - "These results indicate that perospirone and blonanserin may cause the hypotension-induced, reflex-mediated increase of sympathetic tone, leading to the increase of inward Ca current in the heart except that the high dose of perospirone reversed them. Thus, blonanserin may have more potential to produce intracellular Ca overload triggering early afterdepolarization than perospirone, which might explain the onset of TdP in the LQT3 patient."
