Clozapine is associated with various haematological adverse effects, including leukopenia, neutropenia, agarnulocytosis, leukocytosis, anaemia, eosinophilia, thrombocytopenia and thrombocythaemia. Recognition and treatment of clozapine-related seizures also will become increasingly important as clozapine use grows in the 1990s. The decision to stop clozapine as a result of haematological advers...

Clozapine, an ideal antipsychotic drug for the treatment of resistant schizophrenia, is considered the most underutilised treatment for schizophrenia. However, safety concerns have been raised about clozapine-induced cardiotoxicity, which may lead to sudden death, particularly in young patients. The exact mechanism of clozapine cardiotoxicity has not yet been thoroughly studied. This study aime...

Clozapine is an atypical antipsychotic with therapeutic efficacy in treatment-resistant schizophrenia patients and low incidence of extrapyramidal side effects. However, the use of clozapine has been limited by its adverse effects on metabolism. Artesunate is a semisynthetic derivative of artemisinin and was shown to decrease the plasma cholesterol and triglyceride in rabbits and rats in recent...

OBJECTIVE To compare the efficacy and safety of clozapine in drug induced psychosis in Parkinson's disease (PD). METHODS A four week, randomised, double blind, parallel comparison of clozapine and placebo, followed by a 12 week clozapine open period, plus a one month period after drug discontinuation, in 60 patients with PD. The primary efficacy outcome was the "clinical global impression sca...

Materials and methods The subjects were hospitalized schizophrenic patients who began to receive clozapine and subsequently had monthly body weight monitoring during the entire study period. Chart reviews were conducted to obtain gender, age at initiation of clozapine treatment, baseline Body Mass Index (BMI), BMI changes after the initiation of clozapine treatment, treatment duration with cloz...

Clozapine is a second-generation antipsychotic agent from the benzodiazepine group indicated for treatment-resistant schizophrenia and other psychotic conditions. Using clozapine earlier on once a case appears to be refractory limits both social and personal morbidity of chronic psychosis. However treatment with second-generation antipsychotics is often complicated by adverse effects. We presen...

Clozapine is an antipsychotic medication with superior efficacy in treatment refractory schizophrenia. The molecular basis of clozapine's therapeutic profile is not well understood. We studied behavioral effects of clozapine in Caenorhabditis elegans to identify novel pathways that modulate clozapine's biological effects. Clozapine stimulated egg laying in C. elegans in a dose-dependent manner....

Clozapine is one of the most promising medications for managing schizophrenia but it is under-utilized because of the challenges of maintaining serum levels in a safe therapeutic range (1-3μM). Timely measurement of serum clozapine levels has been identified as a barrier to the broader use of clozapine, which is however challenging due to the complexity of serum samples. We demonstrate a robust...

OBJECTIVE This study examined the utility of adenine for preventing clozapine-induced neutropenia. METHODS This retrospective study examined the effect of adenine on clozapine-induced neutropenia in patients with treatment- resistant schizophrenia and was conducted at Okehazama Hospital in Japan from July 2010 to June 2013. Adenine was available for use from June 2011 onwards. Twenty-one pati...

BACKGROUND Clozapine is currently restricted to patients who have failed at least two trials of other antipsychotic medications because of concerns that its use as a first-line agent would lead to greater mortality, mainly through agranulocytosis. AIMS OF THE STUDY We sought to determine the cost-effectiveness of allowing clozapine to be a first-line treatment versus the current policy of res...
