olanzapine and Galactorrhea

No clear recommendations exist regarding which antipsychotic drug should be prescribed first for a patient suffering from psychosis. The primary aims of this naturalistic study were to assess the head-to-head effectiveness of first-line second-generation antipsychotics with regards to time until drug discontinuation, duration of index admission, time until readmission, change of psychopathology scores and tolerability outcomes.. Patients >or= 18 years of age admitted to the emergency ward for symptoms of psychosis were consecutively randomized to risperidone (n = 53), olanzapine (n = 52), quetiapine (n = 50), or ziprasidone (n = 58), and followed for up to 2 years.. A total of 213 patients were included, of which 68% were males. The sample represented a diverse population suffering from psychosis. At admittance the mean Positive and Negative Syndrome Scale (PANSS) total score was 74 points and 44% were antipsychotic drug naïve. The primary intention-to-treat analyses revealed no substantial differences between the drugs regarding the times until discontinuation of initial drug, until discharge from index admission, or until readmission. Quetiapine was superior to risperidone and olanzapine in reducing the PANSS total score and the positive subscore. Quetiapine was superior to the other drugs in decreasing the PANSS general psychopathology subscore; in decreasing the Clinical Global Impression - Severity of Illness scale score (CGI-S); and in increasing the Global Assessment of Functioning - Split version, Functions scale score (GAF-F). Ziprasidone was superior to risperidone in decreasing the PANSS positive symptoms subscore and the CGI-S score, and in increasing the GAF-F score. The drugs performed equally with regards to most tolerability outcomes except a higher increase of hip-circumference per day for olanzapine compared to risperidone, and more galactorrhoea for risperidone compared to the other groups.. Quetiapine appears to be a good starting drug candidate in this sample of patients admitted to hospital for symptoms of psychosis..

This open-label, prospective, 4-month study in hyperprolactinemic patients with schizophrenia explored whether prolactin levels decrease after switching antipsychotic therapy to olanzapine. A secondary objective was to determine if reproductive morbidities and sexual dysfunction occurring with hyperprolactinemia improved with prolactin normalization. Clinically stable patients with schizophrenia, who had hyperprolactinemia defined as >18.8 ng/ml for males and >24.2 ng/ml for females, were randomized to: remain on current therapy (n=27) or switch to olanzapine, 5-20 mg/day, (n=27). Baseline prolactin levels in female patients randomized to receive olanzapine (n=14) were 66.3+/-38.7 ng/ml and were 82.0+/-37.6 (p=.32) in those remaining on their pre-study antipsychotic medication (n=14). In male patients, baseline prolactin levels were 33.7+/-12.1 and 33.5+/-13.8 ng/ml (p=.97), respectively, for those randomized to olanzapine (n=13) or remaining on pre-study treatment (n=13). At study end, patients switched to olanzapine experienced significant reductions in mean serum prolactin levels of 19.8+/-18.1 ng/ml in males (p=.02), and 32.3+/-47.5 ng/ml in females (p=.01), but prolactin continued to be elevated in patients who remained on pre-study antipsychotic treatment. After switching to olanzapine treatment, male patients experienced significantly (p=.03) increased free testosterone levels but there were no significant improvements in total testosterone levels; some female patients experienced improved menstrual cycling, as well as resolution of galactorrhea and gynecomastia, and sexual functioning was significantly improved in both genders. Patients switched to olanzapine, as well as those remaining on their pre-study medication, maintained clinical stability, their symptoms continued to improve, although there were no significant between-treatment differences in improvement. Treatment-emergent adverse events did occur in both treatment groups; however, they were not significantly different between groups. Olanzapine-treated patients experienced significantly lower eosinophil counts and higher elevations in low-density lipoproteins and standing blood pressure than non-switched patients. Olanzapine treatment may offer sustained reduction in serum prolactin and improvement in sexual and reproductive comorbid symptoms in patients with schizophrenia who have treatment-emergent hyperprolactinemia.

This study was conducted to prospectively examine the effect of switching from risperidone to olanzapine on female schizophrenia patients who experienced menstrual disturbances, galactorrhea, and/or sexual dysfunction.. Twenty female patients with DSM-IV schizophrenia who were taking risperidone and were suffering from menstrual disturbances, galactorrhea, and/or sexual dysfunction were enrolled. Patients were switched from risperidone to olanzapine over a 2-week period, then treated with olanzapine for 8 additional weeks. The serum prolactin concentrations were examined every 2 weeks. The Positive and Negative Syndrome Scale (PANSS), Abnormal Involuntary Movement Scale (AIMS), Simpson-Angus Scale for Extrapyramidal Symptoms (SAS), and questions from the Dickson-Glazer Sexual Functioning Scale were administered to evaluate efficacy, extrapyramidal side effects, and sexual and reproductive functioning at baseline and the endpoint of 10 weeks.. Serum prolactin levels decreased significantly (p < .01) following the switch from risperidone to olanzapine. Scores of PANSS, AIMS, and SAS at the endpoint were also significantly decreased (p < .01) compared to those of baseline. Patients experienced improvements in menstrual functioning and perceptions of sexual side effects.. Olanzapine reversed hyperprolactinemia in risperidone-treated female schizophrenic patients. This was associated with a decrease in amenorrhea, improved cycle regularity, and a decrease in sexual side effects that the women attributed to antipsychotic medication. This study suggests that switching to olanzapine is a safe and effective alternative method for patients with antipsychotic-induced hyperprolactinemia associated sexual and/or reproductive dysfunction. Long-term follow-up studies are warranted, with particular attention to the course of sexual and reproductive dysfunction.

Although these agents are used frequently, prospective data comparing serotonin/dopamine antagonists/partial agonists (SDAs) in youth regarding prolactin levels and sexual adverse effects (SeAEs) are scarce.. Youth aged 4 to 17 years, SDA-naive (≤1 week exposure) or SDA-free for ≥4 weeks were followed for ≤12 weeks on clinician's-choice aripiprazole, olanzapine, quetiapine, or risperidone. Serum prolactin levels, SDA plasma levels, and rating scale-based SeAEs were assessed monthly.. Altogether, 396 youth (aged 14.0 ± 3.1 years, male participants = 55.1%, mood spectrum disorders = 56.3%, schizophrenia spectrum disorders = 24.0%, aggressive-behavior disorders = 19.7%; SDA-naive = 77.8%) were followed for 10.6 ± 3.5 weeks. Peak prolactin levels/any hyperprolactinemia/triple-upper-limit-of-normal-prolactin level were highest with risperidone (median = 56.1 ng/mL/incidence = 93.5%/44.5%), followed by olanzapine (median = 31.4 ng/mL/incidence = 42.7/76.4%/7.3%), quetiapine (median = 19.5 ng/mL/incidence = 39.7%/2.5%) and aripiprazole (median = 7.1 ng/mL/incidence = 5.8%/0.0%) (all p < .0001), with peak levels at 4 to 5 weeks for risperidone and olanzapine. Altogether, 26.8% had ≥1 newly incident SeAEs (risperidone = 29.4%, quetiapine = 29.0%, olanzapine = 25.5%, aripiprazole = 22.1%, p = .59). The most common SeAEs were menstrual disturbance = 28.0% (risperidone = 35.4%, olanzapine = 26.7%, quetiapine = 24.4% aripiprazole = 23.9%, p = .58), decreased erections = 14.8% (olanzapine = 18.5%, risperidone = 16.1%, quetiapine = 13.6%, aripiprazole = 10.8%, p = .91) and decreased libido = 8.6% (risperidone = 12.5%, olanzapine = 11.9%, quetiapine = 7.9%, aripiprazole = 2.4%, p = .082), with the least frequent being gynecomastia = 7.8% (quetiapine = 9.7%, risperidone = 9.2%, aripiprazole = 7.8%, olanzapine = 2.6%, p = 0.61), galactorrhea = 6.7% (risperidone = 18.8%, quetiapine = 2.4%, olanzapine = 0.0%, aripiprazole = 0.0%, p = .0008), and mastalgia = 5.8% (olanzapine = 7.3%, risperidone = 6.4%, aripiprazole = 5.7%, quetiapine = 3.9%, p = .84). Postpubertal status and female sex were significantly associated with prolactin levels and SeAEs. Serum prolactin levels were rarely associated with SeAEs (16.7% of all analyzed associations), except for the relationship between severe hyperprolactinemia and decreased libido (p = .013) and erectile dysfunction (p = .037) at week 4, and with galactorrhea at week 4 (p = .0040), week 12 (p = .013), and last visit (p < .001).. Risperidone, followed by olanzapine, was associated with the largest prolactin elevations, with little prolactin-elevating effects of quetiapine and, especially, aripiprazole. Except for risperidone-related galactorrhea, SeAEs did not differ significantly across SDAs, and only galactorrhea, decreased libido, and erectile dysfunction were associated with prolactin levels. In youth, SeAEs are not sensitive markers for significantly elevated prolactin levels.

The frequency of severe adverse drug reactions (ADRs) from psychotropic drugs was investigated in hospitalised psychiatric patients in relation to their age. Specifically, the incidence of ADRs in patients up to 60 years was compared to that of patients older than 60 years.. Prescription rates of psychotropic drugs and reports of severe ADRs were collected in psychiatric hospitals in Switzerland between 2001 and 2010. The data stem from the drug surveillance programme AMSP.. A total of 699 patients exhibited severe ADRs: 517 out of 28,282 patients up to 60 years (1.8%); 182 out of 11,446 elderly patients (1.6%, ns). Logistic regression analyses showed a significantly negative relationship between the incidence of ADRs and patients' age in general and in particular for weight gain, extrapyramidal motor system (EPMS) symptoms, increased liver enzymes and galactorrhoea. A significantly negative relationship was observed for age and the dosages of olanzapine, quetiapine, risperidone, valproic acid and lamotrigine. When comparing age groups, frequency of ADRs was lower in general for antipsychotic drugs and anticonvulsants, in particular for valproic acid in the elderly. Weight gain was found to be lower in the elderly for antipsychotic drugs, in particular for olanzapine. For the group of mood-stabilising anticonvulsants (carbamazepine, lamotrigine and valproic acid) the elderly exhibited a lower incidence of reported allergic skin reactions.. The results suggest that for psychiatric inpatients the incidence of common severe ADRs (e.g., weight gain or EPMS symptoms) arising from psychotropic medication decreases with the age of patients.

The International Schizophrenia Outpatient Health Outcomes study, IC-SOHO is a three-year international observational study that investigates clinical and health outcomes of antipsychotic treatments. 7658 outpatients treated for schizophrenia were enrolled in the study, who needed an antipsychotic therapy to initiate or switch. The primary analysis compared the group taking olanzapine with the group taking any other antipsychotics, while the secondary comparison was performed between those treated with olanzapine and those with risperidone. Efficacy analysis was carried out based on changes in Clinical Global Impression of Severity scale (CGI-S), which was performed at a global symptom level, as well as with respect to the patients' positive, negative, cognitive and depressive symptoms. In addition, adverse events were also evaluated. Results of the analysis of the 3- and 6-month data from Hungary are disclosed in this publication. 200 patients were enrolled in the country. Demographics of the treatment groups were not significantly different. At 3 and 6 months after treatment initiation, there were no significant between-group differences in improvement of global symptomatology, however, cognitive symptoms improved more in the Olanzapine-group compared to those taking other antipsychotics (p<0.05). In patients showing Extrapyramidal Symptoms (EPS) at baseline, these symptoms finished to a greater extent among those receiving olanzapine than in those receiving other antipsychotics (after 6 months D<0.0001). Half a year later, significantly less patients showed extrapyramidal adverse events (p=0,0007), and the previous EPS terminated to a greater extent (p=0.0016) in the olanzapine group, as compared to those taking risperidone. No between-group differences were found in changes of sexual functions, as well as of weight and Body Mass Index measures. Switching antipsychotic initiated at study baseline, and adding-on one or more other antipsychotic to the initial one, were significantly less frequent in the Olanzapine-group compared to those initiated other antipsychotics. In the first 3 months, treatment compliance was significantly higher with olanzapine therapy than with other antipsychotic treatments, and with risperidone respectively. Results from the Hungarian sample correspond with results from higher analysis levels of wider patient populations of IC-SOHO study. Olanzapine showed outstanding efficacy in lessening cognitive disturbances and global cli

To analyze the disproportionality of reporting of hyperprolactinemia, galactorrhea, and pituitary tumors with seven widely used antipsychotic drugs.. Retrospective pharmacovigilance study.. United States Food and Drug Administration's Adverse Event Reporting System (AERS) database.. We initially identified higher-than-expected postmarketing reports of pituitary tumors associated with risperidone, a potent dopamine D2-receptor antagonist antipsychotic, by analyzing reporting patterns of these tumors in the AERS database. To further examine this association, we analyzed disproportionate reporting patterns of pituitary tumor reports for seven antipsychotics with different affinities for blocking D2 receptors: aripiprazole, clozapine, olanzapine, quetiapine, risperidone, ziprasidone, and haloperidol.. To conduct both of these analyses, we used the Multi-item Gamma Poisson Shrinker (MGPS) data mining algorithm applied to the AERS database. The MGPS uses a Bayesian model to calculate adjusted observed:expected ratios of drug-adverse event associations (Empiric Bayes Geometric Mean [EBGM] values) in huge drug safety databases. The higher the adjusted reporting ratio, or EBGM value, the greater the strength of the association between a drug and an adverse event. Risperidone had the highest adjusted reporting ratios for hyperprolactinemia (EBGM 34.9, 90% confidence interval [CI] 32.8-37.1]), galactorrhea (EBGM 19.9, 90% CI 18.6-21.4), and pituitary tumor (EBGM 18.7, 90% CI 14.9-23.3) among the seven antipsychotics, and one of the highest scores for all drugs in the AERS database. Some tumors were associated with visual field defects, hemorrhage, convulsions, surgery, and severe (>10-fold) prolactin elevations. The EBGM values for risperidone for these adverse events were higher in women, but high EBGM values for these events were also seen in men and children. Moreover, the rank order of the EBGM values for pituitary tumors corresponded to the affinities of these seven drugs for D2 receptors.. Treatment with potent D2-receptor antagonists, such as risperidone, may be associated with pituitary tumors. These findings are consistent with animal (mice) studies and raise the need for clinical awareness and longitudinal studies.

The increased serum prolactin is one of the side effects of antipsychotic treatment. The clinical signs of its elevated level are galactorrhea, gynecomastia, breast tenderness and sexual dysfunction. These symptoms can cause poor compliance and relapse of the psychiatric illnesses. The possible clinical interventions are: 1) reduce of the dose of the psychotropic drug and/or addition of a dopamine agonist; 2) switch to another drug. The aim of our study was to evaluate the results of the switch to quetiapine in the cases of elevated prolactin with galactorrhea.. Five of our patients (from the January to July in 2005) treated for more than two months with new generation antipsychotics had the symptoms of galactorrhea/breast tenderness. The diagnoses in according to ICD-10 were: schizophrenia and schizoaffective disorder. The differential-diagnostic examination were: physical, neuroimaging and laboratory including prolactin level followed up on the 4th, 8th weeks after the therapeutical intervention.. The galactorrhoea disappeared and prolactin levels normalized after the switching to quetiapine. In the case of bromocriptine addition to previous therapy symptom stopped but the hormone level did not change significantly. There was remission and/or stabilisation of psychotic symptoms with quetiapine.. The galactorrhea is one of the possible side effects of psychotropic drugs. We presented five patients with this kind of symptoms related to antipsychotic treatment. After the switch to quetiapine the galactorrhea and breast tenderness stopped, the level of prolactin normalized and the psychiatric condition of the patients showed remission. Our data support the benefit of the switch to another new generation drug, first of all to quetiapine, in the cases of galactorrhea and/or elevated prolactin level related to the antipsychotic pharmacotherapy.

The European Schizophrenia Out-patient Health Outcomes study is an observational study investigating treatment in schizophrenia. We report treatment-emergent adverse events during the first 6 months of treatment.. The rate of extrapyramidal symptoms (EPS), anticholinergic use, weight gain and sexual related dysfunctions were assessed in 8,400 out-patients.. Patients typical antipsychotics and risperidone experienced significantly more EPS and anticholinergic use than patients in the clozapine, olanzapine, and quetiapine cohorts. Patients treated with amisulpride, typical antipsychotics and risperidone were significantly more likely to have sexual related dysfunctions and/or amenorrhea. Increases in weight and body mass index occurred in all cohorts, but were significantly greater in the olanzapine and clozapine cohorts.. Patients treated with olanzapine, quetiapine and clozapine had better tolerability outcomes regarding EPS and sexual related dysfunctions compared with patients receiving risperidone, amisulpride and typicals. Patients treated with olanzapine and clozapine had higher weight increases than patients treated with risperidone, quetiapine and typicals.
