BACKGROUND: Clozapine is a very effective therapeutic option for schizophrenic disorders that have been refractory to most other therapies. This extremely positive aspect clashes easily with an adverse effect of the drug that is deemed to be a very dangerous one: agranulocytosis. We asked whether the mandatory strict hematological follow-up prescribed in the black box warning of clozapine's label is proportioned to the actual incidence of agranulocytosis, considering that is the main reason that such a drug is often used only late in the treatment course...

PURPOSE/BACKGROUND: Phenibut (4-amino-3-phenyl-butyric acid) is a structural analog of GABA with central nervous system depressant and anxiolytic properties, developed in the former Soviet Union for anxiety, insomnia, and alcohol withdrawal. Its primary mechanism of action is believed to be a GABA-B receptor agonist-with high affinity at the α2δ subunit-containing voltage-dependent calcium channels and therefore gabapentinoid activity-as well as, to a lesser extent, GABA-A agonist activity...

In our report, and review of the literature, we present an important clinical lesson for the recognition and treatment of alprazolam withdrawal with complicated delirium and psychosis, and present a strong case for future treatment algorithms. Our case is unique due to the severity of behavioral disturbance associated with acute psychosis secondary to alprazolam withdrawal and the significant quantity of alprazolam consumed. The use of high cumulative doses of longer-acting benzodiazepines resulted in rapid improvement in symptoms with full resolution of psychosis...

BACKGROUND: Since insomnia and depression are interrelated, improved sleep early in antidepressant pharmacotherapy may predict a positive treatment outcome. We investigated whether early insomnia improvement (EII) predicted treatment outcome in psychotic depression (PD) and examined if there was an interaction effect between EII and treatment type to assess if findings were treatment-specific. METHODS: This study is a secondary analysis of a randomized trial comparing 7 weeks treatment with the antidepressants venlafaxine, imipramine and venlafaxine plus the antipsychotic quetiapine in PD (n = 114)...

Many women with bipolar disorder experience episodes of illness or relapses over the perinatal period, especially in the immediate postpartum period. Risks associated with treated/untreated psychopathologies and fetal exposure to bipolar medications make the management of bipolar disorder during these periods challenging for clinicians and patients. In light of the available effectiveness and reproductive safety data, the current clinical update based on the opinions of a group of international perinatal psychiatry authors recommends general considerations and specific management strategies for each possible clinical scenario, including mixed features, predominant polarity, diagnosis of subtypes of bipolar disorder, severity of previous episodes, and risk of recurrence of mood episodes...

BACKGROUND: The purpose of this study was to review the association between the SLC6A4 5-HTTLPR polymorphism and antidepressant (AD)-associated treatment emergent mania (TEM) in bipolar disorder alongside starting a discussion on the merits of developing risk stratification models to guide when not to provide AD treatment for bipolar depression. METHODS: Studies that examined the association between clinical and genetic risk factors, specifically monoaminergic transporter genetic variation, and TEM were identified...

BACKGROUND: The clinical assessment of adherence to clozapine may prove difficult. METHOD: We studied the incidence of nonadherence (plasma clozapine <0.01 mg L -1 ) in samples submitted to a clozapine therapeutic drug monitoring (TDM) service, 1993-2017. RESULTS: Clozapine was not detected in 2865 samples from men (2214 patients, 1.1% of all samples from men) and 1068 samples from women (822 patients, 1.0% of all samples from women). Information on the prescribed dose was supplied for 1623 of these samples from men and 492 of these samples from women...

BACKGROUND: Little information is available on clozapine discontinuation rates in developing country settings. AIM: The present study aimed to evaluate the incidence and reasons clinicians stopped clozapinine in patients after initiating treatment with the same. In addition, the study also aimed to assess the rechallenge rate, that is, restarting clozapine after a decision to discontinue the same by the clinicians. METHODOLOGY: The treatment records of 859 patients started on clozapine were reviewed to identify the patients for whom the clinician stopped clozapine at least once because of any reason...
