Quantitative Resting State Electroencephalography in Patients with Schizophrenia Spectrum Disorders Treated with Strict Monotherapy Using Atypical Antipsychotics
Original Article https://doi.org/10.9758/cpn.2021.19.2.313 pISSN 1738-1088 / eISSN 2093-4327 Clinical Psychopharmacology and Neuroscience 2021;19(2):313-322 Copyrightⓒ 2021, Korean College of Neuropsychopharmacology Quantitative Resting State Electroencephalography in Patients with Schizophrenia Spectrum Disorders Treated with Strict Monotherapy Using Atypical Antipsychotics Takashi Ozaki1,2, Atsuhito Toyomaki1, Naoki Hashimoto1, Ichiro Kusumi1 1Department of Psychiatry, Graduate School of Medicine, Hokkaido University, 2Department of Psychiatry, Hokkaido Prefectural Koyogaoka Hospital, Sapporo, Japan Objective: The effect of antipsychotic drugs on quantitative electroencephalography (EEG) has been mainly examined by the administration of a single test dose or among patients using combinations of other psychotropic drugs. We therefore investigated the effects of strict monotherapy with antipsychotic drugs on quantitative EEG among schizophrenia patients. Methods: Data from 2,364 medical reports with EEG results from psychiatric patients admitted to the Hokkaido University Hospital were used. We extracted EEG records of patients who were diagnosed with schizophrenia spectrum disorders and who were either undergoing strict antipsychotic monotherapy or were completely free of psychotropic drugs. The spectral power was compared between drug-free patients and patients using antipsychotic drugs. We also performed multiple regression analysis to evaluate the relationship between spectral power and the chlorpromazine equivalent daily dose of antipsychotics in all the patients. Results: We included 31 monotherapy and 20 drug-free patients. Compared with drug-free patients, patients receiving antipsychotic drugs demonstrated significant increases in theta, alpha and beta power. When patients taking different types of antipsychotics were compared with drug-free patients, we found no significant change in any spectrum power for the aripiprazole or blonanserin groups. -

Symptoms can be complex and expansive, often leading to symptoms representing other disorders in addition to the primary reason for treatment. In particular mental health disorders fall prey to this situation. Targeting treatment can be difficult due to the implication of receptors in more than one disorder, and more than one receptor in a single disorder. In the instance of GPCRs, receptors such as the serotonin receptors (and in particular the 5-HT2A for the interest of this research) belong to a large family of receptors, the GPCR Class A super family. -

Antipsychotics (Part-4) FLUOROBUTYROPHENONES
Antipsychotics (Part-4) FLUOROBUTYROPHENONES The fluorobutyrophenones belong to a much-studied class of compounds, with many compounds possessing high antipsychotic activity. They were obtained by structure variation of the analgesic drug meperidine by substitution of the N-methyl by butyrophenone moiety to produce the butyrophenone analogue which has similar activity as chlorpromazine. COOC2H5 N H3C Meperidine COOC2H5 N O Butyrophenone analog The structural requirements for antipsychotic activity in the group are well worked out. General features are expressed in the following structure. F AR Y O N • Optimal activity is seen when with an aromatic with p-fluoro substituent • When CO is attached with p-fluoroaryl gives optimal activity is seen, although other groups, C(H)OH and aryl, also give good activity. • When 3 carbons distance separates the CO from cyclic N gives optimal activity. • The aliphatic amino nitrogen is required, and highest activity is seen when it is incorporated into a cyclic form. • AR is an aromatic ring and is needed. It should be attached directly to the 4-position or occasionally separated from it by one intervening atom. • The Y group can vary and assist activity. An example is the hydroxyl group of haloperidol. The empirical SARs suggest that the 4-aryl piperidino moiety is superimposable on the 2-- phenylethylamino moiety of dopamine and, accordingly, could promote affinity for D2 receptors. The long N-alkyl substituent could help promote affinity and produce antagonistic activity. Some members of the class are extremely potent antipsychotic agents and D2 receptor antagonists. The EPS are extremely marked in some members of this class, which may, in part, be due to a potent DA block in the striatum and almost no compensatory striatal anticholinergic block. -

The objective of this study was to compare the efficacy and safety of blonanserin with haloperidol in Indian patients with schizophrenia. Methodology: This was an 8 week, randomized, open label, active controlled, multicentre study. Patients diagnosed with schizophrenia according to the DSM-IV criteria were enrolled in the study. Patients were randomized to receive either blonanserin (16 mg/day) or haloperidol (4.5 mg/day). Patients were assessed on an out-patient basis after every 2 weeks for clinical efficacy [Positive and Negative Syndrome Scale (PANSS) total and factor scores], Clinical Global Impressions–severity CGI-S, Clinical Global Impressions–Improvement (CGI-I), Global Assessment of Efficacy (CGI-C), adverse events and drug compliance. Results: At our centre, total 60 patients were randomized in the study with 30 patients each in Blonanserin and Haloperidol group. -

Pharmacology Review(S)
CENTER FOR DRUG EVALUATION AND RESEARCH APPLICATION NUMBER: 200603 PHARMACOLOGY REVIEW(S) Tertiary Pharmacology/Toxicology Review From: Paul C. Brown, Ph.D., ODE Associate Director for Pharmacology and Toxicology, OND IO NDA: 200603 Agency receipt date: 12/30/2009 Drug: Lurasidone hydrochloride Applicant: Sunovion Pharmaceuticals (Originally submitted by Dainippon Sumimoto Pharma America, Inc.) Indication: schizophrenia Reviewing Division: Division of Psychiatry Products Background: The pharm/tox reviewer and team leader concluded that the nonclinical data support approval of lurasidone for the indication listed above. Reproductive and Developmental Toxicity: Reproductive and developmental toxicity studies in rats and rabbits revealed no evidence of teratogenicity or embryofetal toxicity. The high doses in the rat and rabbit embryofetal toxicity studies were 3 and 12 times, respectively, the maximum recommended human dose (80 mg) based on a body surface area comparison. Carcinogenicity: Lurasidone was tested in 2 year rat and mouse carcinogenicity studies. These studies were reviewed by the division and the executive carcinogenicity assessment committee. The committee concluded that the studies were adequate and that there was a drug-related increase in mammary carcinomas in female rats at doses of 12 mg/kg and higher and a drug-related increase in mammary carcinomas and adenoacanthomas and pituitary pars distalis adenomas in female mice. The applicant also provided data from various studies showing that lurasidone significantly increases prolactin in several different species including rats and mice. Conclusions: I agree with the division pharm/tox conclusion that this application can be approved from a pharm/tox perspective. The division recommends that lurasidone be labeled with pregnancy category B.
