The Improvement of the Dissolution Rate of Ziprasidone Free Base from Solid Oral Formulations.
Abstract This work aims at increasing solubility and dissolution rate of ziprasidone free base-Biopharmaceutics Classifaction System (BCS) class II compound. The authors describe a practical approach to amorphization and highlight problems that may occur during the development of formulations containing amorphous ziprasidone, which was obtained by grinding in high-energy planetary ball mills or cryogenic mills. The release of ziprasidone free base from the developed formulations was compared to the reference drug product containing crystalline ziprasidone hydrochloride-Zeldox® hard gelatin capsules.

QT Interval Prolongation Associated with Intramuscular Ziprasidone in Chinese Patients: A Case Report and a Comprehensive Literature Review with Meta-Analysis.
Authors: Li XB, Tang YL, Zheng W, Wang CY, de Leon J Abstract Intramuscular (IM) ziprasidone has been associated with QTc interval prolongations in patients with preexisting risk factors. A 23-year-old male Chinese schizophrenia patient experienced an increase of QTc interval of 83 milliseconds (ms) after receiving 20 mg IM ziprasidone (baseline and increased QT/QTc were, respectively, 384/418 and 450/501). This was rated as a probable adverse drug reaction (ADR) by the Liverpool ADR causality assessment tool. A systematic review including all types of trials reporting the effect of IM ziprasidone on the QTc...

Hyperprolactinemia and estimated dopamine D2 receptor occupancy in patients with schizophrenia: Analysis of the CATIE data
Conclusion The threshold for hyperprolactinemia in D2 occupancy may lie somewhat on a lower side of the established therapeutic window with antipsychotics (i.e. 65–80%). This finding highlights the need for the use of the lowest possible dose to avoid this hormonal side effect in the treatment of schizophrenia.

New Drugs of Abuse
Drug abuse is a common problem and growing concern in the United States, and over the past decade, novel or atypical drugs have emerged and have become increasingly popular. Recognition and treatment of new drugs of abuse pose many challenges for health care providers due to lack of quantitative reporting and routine surveillance, and the difficulty of detection in routine blood and urine analyses. Furthermore, street manufacturers are able to rapidly adapt and develop new synthetic isolates of older drugs as soon as law enforcement agencies render them illegal. In this article, we describe the clinical and adverse effects...

Ziprasidone monotherapy is ineffective for bipolar-associated anxiety
What is already known on this topic? Anxiety disorders are common among patients with bipolar disorder. Bipolar patients with anxiety disorders have poorer treatment outcomes, greater numbers of suicide attempts, higher rates of substance abuse and lower quality of life.1 Complicating treatment, standard antianxiety agents, such as antidepressants, may worsen the course of bipolar disorder, and there is conflicting evidence about antipsychotics. Some data support the use of quetiapine2 or olanzapine for the treatment of bipolar anxiety, while one trial found risperidone to be ineffective.3 What does this paper add? Ziprasi...

Comparative efficacy and acceptability of drug treatments for bipolar depression: a multiple‐treatments meta‐analysis
ConclusionOlanzapine + fluoxetine should be first‐line treatment. Olanzapine, quetiapine, lurasidone, valproate and selective serotonin re‐uptake inhibitors are also recommended. Tricyclic antidepressants and lithium are worthy of consideration but lamotrigine (high risk of switching, less robust efficacy) and MAOIs, ziprasidone, aripiprazole and risperidone (no evidence of efficacy) should not be used.

Management of Psychosis and Agitation in Medical-Surgical Patients Who Have or Are at Risk for Prolonged QT Interval
We review the literature on management of psychosis and agitation in medical-surgical patients who have or are at risk for prolonged QT interval, a risk factor for torsade de pointes (TdP), and we describe our protocols for treating these patients. We searched PubMed and PsycInfo for relevant studies and found few papers describing options for treating psychosis and agitation in these patients. Prolonged QTc interval has been more often associated with low-potency phenothiazines such as thioridazine; however, it may occur with high potency typical antipsychotics such as fluphenazine and haloperidol as well as with atypical...

Conclusions: This method for determining antipsychotic dose equivalence entails an operationalized and evidence-based approach that can be applied to the various antipsychotic drugs. As a limitation, the results are not applicable to specific populations such as first-episode or refractory patients. We recommend that alternative methods also be updated in order to minimize further differences between the methods and risk of subsequent bias. (Source: Schizophrenia Bulletin)

[Correspondence] Efficacy of antipsychotic drugs for schizophrenia
We read with great interest Stefan Leucht and colleagues' meta-analysis (Sept 14, p 951). It is remarkable that the five newest antipsychotics—ziprasidone, aripiprazole, asenapine, iloperidone, and lurasidone—are at the bottom of the efficacy and all-cause discontinuation figures, although there are no known pharmacological differences to explain these findings. Here, we suggest that they form a subclass of antipsychotics with administration issues that lower total drug exposure. We believe that pharmacokinetics can explain the differences in efficacy of antipsychotics. (Source: LANCET)

[Correspondence] Efficacy of antipsychotic drugs for schizophrenia – Authors' reply
Philippe Vincent and Edouard Kouassi make a valid point about the complex pharmacokinetics of some newer antipsychotic drugs. We believe that knowledge of these pharmacokinetics is essential for getting the best results from treatment and that these issues might be under-recognised in clinical practice. For example, even though the majority of the trials included in our meta-analysis were phase 3 studies with strict protocols, it cannot be ruled out that ziprasidone or lurasidone were sometimes taken without sufficient food.

Clinical and regulatory implications of active run‐in phases in long‐term studies for bipolar disorder
ConclusionExtrapolation of results from enrichment studies to the more general population of patients should be carried out cautiously because average treatment benefits are likely to be less in unselected patients. Clear guidance for regulatory submission of RCTs is needed. (Source: Acta Psychiatrica Scandinavica)

Effectiveness of antipsychotic drugs against hostility in patients with schizophrenia in the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) study.
This study aimed to compare the effects of olanzapine, perphenazine, risperidone, quetiapine, and ziprasidone on hostility in schizophrenia. METHODS: We used the data that were acquired in the 18-month Phase 1 of the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) study. We analyzed the scores of the Positive and Negative Syndrome Scale (PANSS) hostility item in a subset of 614 patients who showed at least minimal hostility (a score ≥ 2) at baseline. RESULTS: The primary analysis of hostility indicated an effect of difference between treatments (F4,1487 = 7.78, P

Quetiapine versus other atypical antipsychotics for schizophrenia.
CONCLUSIONS: Available evidence from trials suggests that most people who start quetiapine stop taking it within a few weeks (around 60%). Comparisons with amisulpride, sertindole and zotepine do not exist. Although efficacy data favour olanzapine and risperidone compared with quetiapine, the clinical meaning of these data remains unclear. Quetiapine may produce fewer parkinsonian effects than paliperidone, aripiprazole, ziprasidone, risperidone and olanzapine. Quetiapine appears to have a similar weight gain profile to risperidone, as well as clozapine and aripiprazole (although data are very limited for the latter t...

Association of ADRA2A and MTHFR gene polymorphisms with weight loss following antipsychotic switching to aripiprazole or ziprasidone
ConclusionThe study data indicated that carriage of the ADRA2A rs1800544 GG genotype and the MTHFR rs1801131 C allele are associated with BMI reduction in this population following switching of antipsychotics to aripiprazole and ziprasidone.
