Recently, there has been interest in melperone

as a possible alternative to clozapine. This retrospective case series examines the outcomes for enough patients with refractory schizophrenia treated with melperone at the South London and Maudsley NHS Foundation Trust where it was first used in the UK. The South London and Maudsley NHS Foundation Trust provides a range of mental health and Inhibitors,research,lifescience,medical substance misuse services in the UK. It provides care and treatment for a local population of 1.1 million people in South London. In addition, there are specialist services for people from across the selleck chemicals Volasertib country. The National Psychosis Unit is one of such tertiary referral services for the treatment of patients with refractory schizophrenia and melperone was first used here in the UK in 2005. This is thus the first published evidence of the experience with melperone in the UK. Method Using the pharmacy database, we identified all patients prescribed melperone from April 2005 to July 2010. From patient medical notes we extracted relevant information on past antipsychotic Inhibitors,research,lifescience,medical treatments and reasons

for prescribing of melperone. For patients treated and discharged from the National Psychosis Unit, we contacted the care team to find out what the current anti-psychotic treatment was. The main outcome was to determine proportion of patients discharged on melperone: a proxy for acceptable treatment outcome. Results In Inhibitors,research,lifescience,medical total, 22 patients were treated with melperone. One patient was excluded as she Inhibitors,research,lifescience,medical was treated for less than a week. Tables 1 and ​and22 give patient characteristics.

Table 1. Patient characteristics: summary. Table 2. Patient characteristics and outcome. This sample comprised patients with severe and treatment-refractory illness. The average age of onset Inhibitors,research,lifescience,medical of illness was 19 years of age. Almost all patients (18/21, 86%) had a prior exposure to clozapine. Of these, 10 patients had discontinued it because of adverse effects, 6 because of noncompliance with medication or blood tests and 2 patients because of inadequate response. Three patients had no prior exposure to clozapine. In two patients, this was because they had low baseline neutrophil counts and so they were ineligible for clozapine treatment. The third patient had not been exposed to clozapine because of a refusal to comply. Duration of treatment Three (14%) patients were discharged on melperone and 18 patients discontinued treatment Batimastat during their stay on the unit. Of those who stopped treatment, the mean duration of treatment was 5.4 months. Of the three patients who were discharged on melperone, one was lost to follow up while two continued to take melperone at follow up, one for 4 years 11 months and the other for 4 years. Reason for discontinuation of treatment The primary reason for discontinuation of melperone was lack of efficacy in 13/18 (72%) of patients. Four patients were poorly compliant and so melperone was stopped.
