Schizophrenia is a chronic and severe mental illness associated with substantial morbidity and mortality. Antipsychotics primarily rely on direct dopamine blockade, leading to potential life-interfering adverse events. The purpose of this review is to describe the safety and efficacy of xanomeline-trospium (Cobenfy), a Food and Drug Administration approved treatment for schizophrenia in adults.

Introduction/objective: Schizophrenia with substance use disorder is a complex clinical condition that may increase treatment resistance. Cannabis use disorder is frequently associated with psychosis and the causal link has still to be defined. Partial D2/3 agonists may ensure limbic dopamine release normalization while avoiding reduced frontocortical dopamine release, which would contribute to negative symptoms.

Dopamine (DA) is an important catecholamine neurotransmitter and its abnormal concentration is closely related to diseases such as hypertension, Parkinson's disease and schizophrenia. Due to the advantages of high sensitivity and fast response for electrochemiluminescence (ECL), developing ECL sensors for detecting DA was very critical in clinical diagnosis. ECL resonance energy transfer (ECL-RET) was an effective signaling mechanism.

Olanzapine (OLZ) is widely used in the treatment of schizophrenia, and its metabolic side effects have garnered significant attention in recent years. Despite this, the specific side effects of OLZ and the underlying mechanisms remain inadequately understood. To address this gap, zebrafish (Danio rerio) were exposed to OLZ at concentrations of 35.

Population pharmacokinetics of blonanserin in Japanese adolescent and adult patients with schizophrenia.

The second-generation antipsychotic blonanserin is a highly selective, full antagonist of dopamine D and D and serotonin 5-HT receptors. It is currently prescribed for patients with schizophrenia in Japan. We aimed to develop a population pharmacokinetic model of oral blonanserin, including data from 12 to 77 years old patients, to assess the covariates that influence blonanserin pharmacokinetics and evaluate appropriate dosage regimens in adolescents versus adults.
