quetiapine-fumarate and Headache

Disruptive behavior disorders, including conduct disorder, oppositional defiant disorder, and disruptive behavior disorder not otherwise specified, are serious conditions in children and adolescents that include a behavior pattern of violating the basic rights of others and age-appropriate rules or standards and may include aggressive behavior. Although no pharmacotherapy is currently approved for use in this population, evidence suggests that atypical antipsychotic treatment may be useful in patients with these conditions who present with problematic aggression. Currently, research on risperidone shows it to be effective in treating aggressive behavior in this patient population. Limited research is also available on olanzapine, quetiapine, and aripiprazole, but more research is needed on these and other agents. As with any pharmacotherapy, adverse events (including weight gain, headache, and somnolence) should be carefully considered with these medications, especially in children and adolescents, and it is important to properly dose and monitor patients during medication therapy.

To assess the efficacy, safety, and tolerability of brexpiprazole as adjunctive treatment in adults with major depressive disorder (MDD) and an inadequate response to prior antidepressant treatment (ADT).. Patients with a current major depressive episode after prior treatment with 1-3 ADTs entered an 8- or 10-week prospective treatment phase in which they received double-blind placebo adjunct to open-label ADT. Inadequate responders were randomized (2:2:1) to brexpiprazole 2-3 mg/day, placebo, or quetiapine extended-release (XR) 150-300 mg/day, adjunct to the same ADT, for 6 weeks. The primary efficacy endpoint was the change from baseline (randomization) to week 6 in Montgomery-Åsberg Depression Rating Scale (MADRS) total score. The key secondary efficacy endpoint was the change in Sheehan Disability Scale (SDS) mean score.. Adjunctive brexpiprazole showed a greater improvement in MADRS total score than adjunctive placebo (least squares mean difference [95% confidence interval] = -1.48 [-2.56, -0.39]; p = .0078), whereas adjunctive quetiapine XR did not separate from placebo (-0.30 [-1.63, 1.04]; p = .66). Adjunctive brexpiprazole failed to separate from placebo on the SDS mean score (-0.23 [-0.52, 0.07]; p = .13), but did improve functioning on two of the three SDS items (family life and social life). The most frequent treatment-emergent adverse events in patients receiving brexpiprazole were akathisia (6.1%), somnolence (5.6%), and headache (5.6%).. Adjunctive brexpiprazole 2-3 mg/day improved symptoms of depression compared with adjunctive placebo in patients with MDD and an inadequate response to ADTs, and was well tolerated with no unexpected side effects.

Evaluate the efficacy and tolerability of extended release quetiapine fumarate (quetiapine XR) once-daily monotherapy for patients with major depressive disorder (MDD).. In this 10-week, (8-week active treatment phase and 2-week drug-discontinuation/tapering phase), multicenter, parallel-group, placebo-controlled, double-blind, randomized, Phase III study (D1448C00003: Opal), patients initially received quetiapine XR 150 mg/day or placebo. At Week 2, inadequate responders (<20% reduction in MADRS total score) were up-titrated to 300 mg/day quetiapine XR or matching placebo for the final 6 weeks. Primary endpoint: change from randomization to Week 8 in MADRS total score. Secondary endpoints included: MADRS response (≥50% reduction in total score from randomization) and changes from randomization to Week 8 in HAM-D and CGI-S.. 310 patients were randomized. At Week 8, quetiapine XR significantly reduced mean MADRS total score versus placebo (-16.49 vs -13.10, respectively; p<0.01). Mean MADRS score was significantly reduced by quetiapine XR versus placebo at Week 1 (p<0.05). MADRS response rates were significantly greater at Week 8 for quetiapine XR versus placebo (61.9% vs 48.0%, respectively; p<0.05). Significant changes in HAM-D total score and CGI-S were seen at Week 8 for quetiapine XR versus placebo. Withdrawal rates due to AEs were 9.9% and 2.6% for quetiapine XR and placebo, respectively. Common AEs (>10% any group during the randomized phase) for quetiapine XR and placebo, respectively were dry mouth (32.9% and 6.5%), sedation (21.7% and 1.9%), somnolence (20.4% and 5.2%), and headache (10.5% and 10.3%).. The study was not designed to compare quetiapine XR 150 mg/day and 300 mg/day; it was intended to reflect dose titration that might occur in clinical practice.. Quetiapine XR monotherapy is effective in patients with MDD, with symptom improvement seen as early as Week 1, and tolerability results consistent with the known profile of quetiapine.

Combining antipsychotics is common practice in the treatment of schizophrenia. This study investigated aripiprazole adjunctive to risperidone or quetiapine for treating schizophrenia and schizoaffective disorder.. In this multicenter, double-blind, 16-week, placebo-controlled study conducted at 43 American sites from July 2006 to October 2007, patients with chronic, stable schizophrenia or schizoaffective disorder diagnosed with DSM-IV-TR were randomly assigned to receive aripiprazole (2-15 mg/d) or placebo in addition to a stable regimen of quetiapine (400-800 mg/d) or risperidone (4-8 mg/d). The primary outcome measure was the mean change from baseline to endpoint (week 16, last observation carried forward) in the Positive and Negative Syndrome Scale (PANSS) total score.. 323 subjects being treated with either risperidone (n = 177) or quetiapine (n = 146) were randomly assigned to receive adjunctive aripiprazole (n = 168) or placebo (n = 155). Baseline characteristics were similar (mean PANSS total score: aripiprazole, 74.5; placebo, 75.9) except for history of suicide attempts (aripiprazole, 27%; placebo, 40%). Nearly 70% of subjects in each arm completed the trial. Adjunctive aripiprazole and placebo groups were similar in the mean change from baseline to endpoint in the PANSS total score (aripiprazole, -8.8; placebo, -8.9; P = .942). The incidence of treatment-emergent adverse events was similar between groups. Mean changes in Simpson-Angus Scale, Abnormal Involuntary Movement Scale, and Barnes Akathisia Rating Scale scores were not statistically significantly different. Adjunctive aripiprazole was associated with statistically significantly greater decreases in mean serum prolactin levels from baseline than was adjunctive placebo (-12.6 ng/mL for aripiprazole vs -2.2 ng/mL for placebo; P < .001), an effect that was seen in the risperidone subgroup (-18.7 ng/mL vs -1.9 ng/mL; P < .001) but not in the quetiapine subgroup (-3.01 ng/mL vs +0.15 ng/mL; P = .104).. The addition of aripiprazole to risperidone or quetiapine was not associated with improvement in psychiatric symptoms but was generally safe and well tolerated. Further research is warranted to explore whether antipsychotic combination therapy offers benefits to particular patient populations-for example, in cases of hyperprolactinemia.. clinicaltrials.gov Identifier: NCT00325689.

This study examined the efficacy and safety of quetiapine in combination with lithium or divalproex compared with placebo with lithium or divalproex in the prevention of recurrent mood events in bipolar I patients, most recent episode mania, depression, or mixed.. Patients received open-label quetiapine (400-800 mg/day; flexible, divided doses) with lithium or divalproex (target serum concentrations 0.5-1.2 mEq/L and 50-125 microg/mL, respectively) for up to 36 weeks to achieve at least 12 weeks of clinical stability. Patients were subsequently randomized to double-blind treatment with quetiapine (400-800 mg/day) plus lithium/divalproex or placebo plus lithium/divalproex for up to 104 weeks. The primary endpoint was time to recurrence of any mood event.. Treatment with quetiapine in combination with lithium/divalproex significantly increased the time to recurrence of any mood event compared with placebo plus lithium/divalproex. The proportion of patients having a mood event was markedly lower in the quetiapine than in the placebo group (18.5% versus 49.0%). The hazard ratio for time to recurrence of a mood event was 0.28 (P<0.001), a mania event 0.30 (P<0.001), and a depression event 0.26 (P<0.001) corresponding to risk reductions of 72%, 70%, and 74%, respectively. During the randomization phase, the most common adverse events occurring in > or =5% in the quetiapine group were somnolence, nasopharyngitis, and headache. Insomnia was more common in the placebo group. During the randomization phase, there was an increase in weight of 0.5 kg in the quetiapine group and a reduction of 1.9 kg in the placebo group. The incidence and incidence density of a single emergent fasting blood glucose value> or =126 mg/dL was higher with quetiapine than with placebo (9.3% versus 4.1%; 17.6 versus 9.5 patients per 100 patient-years).. This was an enriched sample of patients with bipolar I disorder responding to treatment with quetiapine plus lithium/divalproex.. Maintenance treatment with quetiapine in combination with lithium/divalproex significantly increased time to recurrence of any event (mania, depression, or mixed) irrespective of the polarity of the index episode compared with placebo with lithium/divalproex. Long-term treatment with quetiapine was generally well-tolerated. Quetiapine with lithium/divalproex can provide an effective long-term treatment option for bipolar I disorder to prevent recurrences not only of mania but also depression.

To study the effectiveness, safety, and tolerability of quetiapine in adolescents with psychotic disorders.. This study was an 8-week, open trial using quetiapine with 15 adolescents, ages 13-17 years, mean age 15.1 years, with a diagnosis of a psychotic disorder. Our primary instruments focused on psychotic symptomatology as measured by the Brief Psychiatric Rating Scale (BPRS), Clinical Global Impression (CGI), Positive and Negative Syndrome Scale (PANSS), and the Young Mania Rating Scale (YMRS). Other measures included adverse events, clinical laboratory tests, vital signs, electrocardiogram (ECG), extrapyramidal (EPS) measures, and ophthalmologic examination.. Quetiapine significantly reduced psychotic symptoms as measured by the BPRS, PANSS, YMRS, CGI, and CGI Severity of Illness scale. The average weight gain was 4.1 kg. After correction for expected weight gain, the mean weight gain over the 8-week period was 3.4 kg. Prolactin and cholesterol remained unchanged. Trends were found for a decrease in T4 and an increase in thyroid-stimulating hormone. Common adverse effects were somnolence, agitation, drowsiness, and headache. No significant findings were noted on repeat ECGs, EPS measures, or ophthalmic examination. The final average treatment dose was 467 mg/day (range 300-800 mg/day).. Quetiapine is suggested to be effective treatment of youths with psychotic disorders and to have a favorable side-effect profile.

Quetiapine fumarate (Seroquel [ICI 204,636]) is an atypical dibenzothiazepine antipsychotic with a greater affinity for 5-hydroxytryptamine2 (5-HT2) receptors than for D2 dopamine receptors; its efficacy in patients with schizophrenia was shown in early phase 2 trials (maximum dose, 750 mg/d).. In this multicenter, double-blind, placebo-controlled trial, 286 patients hospitalized with chronic or subchronic schizophrenia (DSM-III-R) were randomized to 6 weeks of treatment with high-dose quetiapine fumarate (< or = 750 mg/d), n = 96; low-dose quetiapine fumarate (< or = 250 mg/d), n = 94; or placebo, n = 96. The Brief Psychiatric Rating Scale (BPRS) and Clinical Global Impression Severity of Illness item scores were the primary efficacy variables. Secondary efficacy variables included the BPRS positive-symptom cluster score, the Modified Scale for the Assessment of Negative Symptoms summary score (United States only), and the total score from the negative scale of the Positive and Negative Syndrome Scale (Europe only). Scores were analyzed using an analysis of covariance for change from baseline at end point with last observations carried forward. The model included baseline score (covariate), center, and treatment. Extrapyramidal symptoms were assessed using the Simpson-Angus Scale and the Barnes Akathisia Scale; abnormal involuntary movements were assessed using the Abnormal Involuntary Movement Scale. Frequency distributions of grouped change-from-baseline scores were analyzed using chi 2 tests.. Of 280 patients in whom the efficacy of quetiapine was evaluated, 159 (42% of those receiving high-dose treatment; 57%, low-dose treatment; and 59%, placebo) withdrew before trial completion, primarily because of treatment failure. Significant (P < .001, BPRS; P = .003, Clinical Global Impression Severity of Illness item; and P = .003, BPRS positive-symptom cluster) differences were identified between patients receiving high-dose quetiapine and placebo for both primary efficacy variables, with end point differences in the BPRS positive-symptom cluster score showing quetiapine's consistency in reducing positive symptoms. The reduction of negative symptoms was less consistent; high-dose quetiapine was superior on the Modified Scale for the Assessment of Negative Symptoms but not on the negative scale of the Positive and Negative Syndrome Scale. Quetiapine was well tolerated and did not induce extrapyramidal symptoms, sustained elevations of prolactin, or clinically significant changes in hematologic parameters.. Quetiapine is an effective antipsychotic with a favorable safety profile. The optimum dose is probably greater than 250 mg/d.

Idiopathic intracranial hypertension (IIH) is a condition associated with poor vision and headaches that can cause disability and reduced quality of life. The onset of IIH is typically associated with sudden weight gain and obesity, which may be due to first-generation or second-generation antipsychotics. This case involved the use of quetiapine in an obese, 28-year-old woman; she gained significant weight after starting the antipsychotic and later developed headaches and blurred vision. Reducing quetiapine and administering acetazolamide significantly improved her symptoms within 4 weeks. This case reminds physicians to consider IIH as a cause of headache and vision loss in patients who have gained weight after starting or increasing quetiapine.
