Switching From Clozapine to Zotepine in Patients With Schizophrenia A 12-Week Prospective, Randomized, Rater Blind, and Parallel Study

open access: yes, 2014
Clozapine is the most effective antipsychotic for patients with treatment-refractory schizophrenia, but many adverse effects are noted. Clinicians usually hesitate to switch from clozapine to other antipsychotics because of the risk of a re-emergence or ...

Extending the ATP9A‐Related Phenotypic Spectrum: Indication of Schizophrenia Susceptibility

open access: yesAmerican Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT ATP9A, which belongs to the P4‐ATPase family of proteins, is involved in the efficient transport of vesicles from the Golgi apparatus to the plasma membrane, as well as the release of extracellular vesicles from human cells. In 2021, a loss‐of‐function variant of this gene was identified as being associated with a recessive neurodevelopmental ...

Clozapine-induced gastrointestinal hypomotility: presenting features and outcomes, UK pharmacovigilance reports, 1992-2017

open access: yes, 2022
Background: Clozapine-induced gastrointestinal hypomotility (CIGH) affects some 75% of patients treated with clozapine. Aims: To document the incidence of potentially harmful CIGH in the UK.

Clozapine:norclozapine ratio as a marker of metabolic risk and therapeutic response and effect of valproate on clozapine levels

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aims Clozapine is the most effective antipsychotic in treatment‐resistant schizophrenia. Clozapine causes weight gain and increased diabetes risk. The role of its metabolite norclozapine and clozapine:norclozapine ratio (CLZ/NCLZ) in metabolic effects has been debated.

The potential influence of estrogen-containing oral contraception on clozapine metabolism in a patient with known pharmacogenomic status [PDF]

open access: yesMental Health Clinician
Clozapine is primarily metabolized via cytochrome P450(CYP)1A2 and to a lesser extent CYP3A4, CYP2C19, and CYP2D6. Metabolic inhibitors of clozapine, such as fluvoxamine and ciprofloxacin, are important to recognize to avoid adverse drug events. Estrogen-

The integrated Lei‐CNS PBPK‐PD model effectively predicts clozapine brain disposition and D2 receptor occupancy in humans

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aim Clozapine, used for treatment‐resistant schizophrenia, has a narrow therapeutic window and highly variable plasma pharmacokinetics (PK), necessitating careful monitoring. Direct measurement of unbound brain PK in humans is unethical. To develop a physiologically based pharmacokinetic–pharmacodynamic (PBPK‐PD) model to predict clozapine brain ...

Evaluation of the effectiveness and acceptability of intramuscular clozapine injection:illustrative case series [PDF]

open access: yes, 2020
Aims and method: A series of eleven patients prescribed intramuscular clozapine at five UK sites is presented. Using routinely collected clinical data, we describe the use, efficacy and safety of this treatment modality.

Virtual Twin Approach Using Physiologically Based Pharmacokinetic Modeling to Support Precision Dosing of Valproic Acid in Geriatric Patients

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Personalized dosing is particularly important for drugs with narrow therapeutic indices in geriatric patients, who exhibit substantial physiological variability and limited pharmacokinetic (PK) evidence to guide individualized dose selection. Valproic acid (VPA) is an effective treatment option for bipolar disorder in older adults, yet dosing largely ...

Monitoring Injected Drug Use in Greece Through Syringe Residue Analysis: A Multicity Study Within the ESCAPE Network

open access: yesDrug Testing and Analysis, EarlyView.
A total of 2121 used syringes were analyzed in Athens, Thessaloniki, and Patras between 2022 and 2024. Distinct drug‐use patterns were observed across the three cities. Benzodiazepines, pregabalin, methadone, and fentanyl were increasingly detected in 2024.

Population‐Stratified Distributions of Post‐Mortem Blood Drug Concentrations: An Epidemiological Framework for Contextual Interpretation

open access: yesDrug Testing and Analysis, EarlyView.
Post‐mortem blood drug concentrations exhibit substantial overlap between deaths in which a drug was implicated and those in which it was not. Analysis of over 58,000 NPSUM cases demonstrates that demographic stratification does not resolve this uncertainty, reinforcing the need for contextual, evidence‐based interpretation rather than concentration ...
