In two 12-week trials buy generic kamagra 100mg on-line impotence 101, risperidone long-acting injection was not found statistically significantly different than risperidone oral tablets in mean change in the PANSS total score or 37 discount 50mg kamagra free shipping erectile dysfunction treatment after prostatectomy, 263 secondary outcome measures order 100 mg kamagra fast delivery erectile dysfunction premature ejaculation treatment. One was a small study of inpatients in Taiwan 100 mg kamagra overnight delivery impotence following prostate surgery, and both studies required patients to be stabilized on oral risperidone prior to the study. The mean dose of oral risperidone prior to study was 3. The dose equivalency was defined as 25 mg every 2 weeks ≤ 4 mg daily oral risperidone; 37. Pain at the injection site was assessed on a 10-point visual analog scale. In the second study, dosing of oral risperidone was stabilized at 2, 4, or 6 mg daily during a run-in period. After randomization to the oral risperidone group, 27% received 2 mg daily, 39% received 4 mg daily, and 34% received 6 mg daily. Among patients randomized to the long-acting injection, 28% received 25 mg every 2 weeks, 39% received 50 mg, and 33% received 75 mg. In both studies, serum prolactin levels were elevated at baseline and decreased at 12 weeks in the risperidone long-acting injection groups (the between-group differences were statistically significant). In a 12-month open-label trial, olanzapine oral tablets were compared with risperidone long-acting injection with no statistically significant differences found between treatments at 13 53 weeks or 12 months based on mean change in PANSS or response rates. Extrapyramidal symptoms were reported in 25% with risperidone and 15% with olanzapine (P<0. In a 12-week placebo-controlled trial, patients randomized to long-acting injection risperidone at all doses had significantly greater improvements from baseline on the PANSS and 235 the CGI. An assessment of the subgroup of patients from this trial who were enrolled as 296 inpatients indicated similar results. Using the SF-36 tool to assess quality of life, the risperidone groups were shown to have greater improvement compared with placebo on 5 of 8 234 items. Short-acting injectables: aripiprazole, olanzapine, ziprasidone Acute agitation The effectiveness of aripiprazole and olanzapine injections in treatment of acute agitation over the first 24 hours in patients with schizophrenia or schizoaffective disorder was compared with 297-300 haloperidol and placebo in 2 trials of each drug. Two were fair-quality dose-ranging studies 299 of intramuscular olanzapine (2. The other 2 300 297 were studies of intramuscular olanzapine 10 mg or intramuscular aripiprazole 9. All of these studies were conducted in multiple countries and were designed to compare the atypical antipsychotic drug to placebo, with comparisons to haloperidol made in secondary analyses. Patients were similar across these trials, with baseline Positive and Negative Syndrome Scale-Excited Component (PANSS-EC) scores of 14-15 or greater, but data were not sufficient to compare other baseline features. Atypical antipsychotic drugs Page 64 of 230 Final Report Update 3 Drug Effectiveness Review Project The studies found both atypical antipsychotic drugs and haloperidol to be superior to placebo based on the mean improvement in the PANSS-EC at 2 hours, with the exception of the 1 mg dose of aripiprazole. A subgroup analysis of those with schizophrenia (excluding those 297 with schizoaffective disorder) found similar results. Data suggest that both drugs may result in statistically significantly greater reductions in PANSS-EC compared with haloperidol and time points before 2 hours. However, these results should be interpreted with caution because these are not clearly stated pre-planned analyses and because the doses of haloperidol (6. Transition to oral therapy One study each of olanzapine and ziprasidone compared with haloperidol examined the 302, 303 transition from injectable to oral dosing over 4 to 7 days. Intramuscular olanzapine 10 mg / oral 5-20 mg daily and intramuscular haloperidol 7. The ziprasidone study found ziprasidone superior to haloperidol in the reduction of 302 the agitation component of the BPRS (P<0. During the oral dosing phase (up to day 7) the differences were not statistically significant. Tolerability and adverse events Atypical antipsychotic drugs have differing adverse event profiles, both in short- and long-term. Adverse events that may lead to mortality or serious morbidity are discussed across disease populations in the section titled Serious Harms. In this section, adverse events that relate to the tolerability of the drugs are discussed for the population of patients with schizophrenia. The adverse events reported here are the overall rate of withdrawal from studies due to adverse events, extrapyramidal symptoms, sexual side effects, weight gain, serum lipids, and metabolic syndrome. Discontinuations from studies due to adverse events Adverse events that are intolerable lead to discontinuation from studies, although some may take longer to result in discontinuation. Such discontinuations take into account the patient’s evaluation of the degree to which the adverse event is tolerable. The CATIE trials included these discontinuations as a secondary outcome measure and found statistically significant differences among the drugs. In CATIE Phase 1, discontinuations due to adverse events were highest among patients taking olanzapine (primarily due to weight gain or other metabolic effects, 18%) and lowest among those taking risperidone (10%; P=0. Time to discontinuation for adverse events did not differ among the groups. In Phases 1B, 2T, and 2E, differences were not seen between groups for rate of discontinuations or time to discontinuation due to adverse events (intolerability). Data from discontinuation rates from 64 head-to-head trials were used in a mixed- treatment comparisons analysis (also known as a network meta-analysis; Table 10). This analysis used direct and indirect comparisons based on the head-to-head trials and found that clozapine resulted in discontinuation due to adverse events statistically significantly more often than olanzapine, immediate-release quetiapine, or risperidone. This analysis controlled for between study heterogeneity and dose level within study (low, medium, or high) by using the fixed- Atypical antipsychotic drugs Page 65 of 230 Final Report Update 3 Drug Effectiveness Review Project effects model. It did not control for within study heterogeneity for those studies where there were more than 2 drug arms. As noted previously, dose comparisons have been an issue in this set of studies, with early studies using doses that are not considered clinically optimal now. For example, early studies of risperidone often used doses well above those used today and clozapine and olanzapine studies used doses below those used today. In stratified sensitivity analysis (studies of greater than 6 months in duration) the findings were no longer statistically significant, although the point estimates were in the same direction was the overall analysis. This is most likely due to the lower number of studies in each stratified analysis. There are fewer data available for the newer drugs, particularly iloperidone, asenapine, and paliperidone long-acting injection. Hence, results for these drugs should be interpreted with caution.

Mixed-treatment effects model: Rates of discontinuation due to adverse events Aripiprazole Asenapine Clozapine Iloperidone Olanzapine Quetiapine Paliperidone Risperidone Ziprasidone 0. Atypical antipsychotic drugs Page 67 of 230 Final Report Update 3 Drug Effectiveness Review Project Because the 3 of 4 short-term trials of iloperidone were published in an abbreviated fashion and because the lower-dose studies did not indicate superiority over placebo in efficacy, there was very limited data available to evaluate comparative harms with iloperidone. A pooled analysis of 3 unpublished 6-week studies indicated that the proportion of patients discontinuing due to adverse events was highest in the risperidone group (6. Similar results were found in a study including 94 ziprasidone: iloperidone (5%, 24 mg daily), ziprasidone (8%, 160 mg daily), and placebo (8%), and in a pooled analysis of 3 longer-term trials (3. Extrapyramidal symptoms 60 In CATIE Phase 1, differences were not found between olanzapine, immediate-release quetiapine, risperidone, or ziprasidone in the incidence of extrapyramidal symptoms identified as an adverse event, or akathisia or movement disorders based on rating scales. Similarly, 77 64 differences were not found between drugs in the subsequent CATIE Phase 1B, Phase 2E, or 78 Phase 2T, or in another trial with multiple drugs (aripiprazole, olanzapine, immediate-release 62 quetiapine, risperidone, and ziprasidone). In a more detailed analysis of only treatment- emergent extrapyramidal symptoms among patients in CATIE, differences in incidence or severity between the atypical antipsychotic drugs were not found based on rating scales for 304 parkinsonism, dystonia, akathisia, or tardive dyskinesia. The use of antiparkinsonism medications was greater with risperidone and lower with immediate-release quetiapine (P=0. In a 52-week trial of olanzapine, immediate-release quetiapine, and risperidone in patients with early psychosis (median duration of illness 6. This study did find statistically significantly more patients taking olanzapine requiring anticholinergic medication for extrapyramidal symptoms compared with immediate- release quetiapine (4% compared with 11%; P=0. Data or analysis for comparison on immediate-release quetiapine and risperidone were not reported. A study of patients with acute schizophrenia, conducted in the inpatient setting over 3 weeks, found no statistically significant difference in symptom scores among aripiprazole, haloperidol, olanzapine, immediate-release 62 quetiapine, risperidone, or ziprasidone. This study reported that 30% of patients taking risperidone and 10% taking immediate-release quetiapine or ziprasidone required anticholinergic medication for extrapyramidal symptoms, while no patient taking aripiprazole or olanzapine did. In head-to-head trials comparing only 2 drugs, differences were not found between 55, 76, 83 olanzapine and immediate-release quetiapine in 3 studies, clozapine and olanzapine in 5 28, 68, 82, 104, 305 38, 65, 99 studies, or olanzapine and aripiprazole in 2 studies. In most cases, some proportion of patients entering the trials had pre-existing extrapyramidal symptoms, such that measures were actually improvements from baseline. Very few trials were specific about measuring new-onset extrapyramidal symptoms as a treatment-emergent adverse event. For all other comparisons made in head-to-head trials, at least some differences were found. Of 10 studies of olanzapine and risperidone (2223 patients total) reporting extrapyramidal 41, 47, 50, 52, 53, 59, symptom adverse event data, 8 found no significant differences between the drugs 82, 306 while 2 (586 patients total) found risperidone to have higher rates or worsening symptoms Atypical antipsychotic drugs Page 68 of 230 Final Report Update 3 Drug Effectiveness Review Project of extrapyramidal symptoms on measures reflecting akathisia, dyskinesia, dystonia, 80, 307 pseudoparkinsonism, and overall extrapyramidal symptoms. Mean doses of risperidone 5 and 7 mg were compared with olanzapine 13 and 17 mg of olanzapine, respectively. Across these studies, size and quality ratings were similar. One good-quality, short-term trial (N=377) was statistically powered to determine a difference in extrapyramidal adverse event reports and found no significant differences between the groups on this measure or on Extrapyramidal 41 Symptom Rating Scale (ESRS) scores or use of anticholinergic medications. In this trial the mean dose of olanzapine was below midrange, while the mean dose of risperidone was near the 23 midpoint (5 mg). The other good-quality trial found treatment-emergent and worsening pre- existing extrapyramidal symptoms in 28. Dosing in this study also had olanzapine slightly below midrange and risperidone within midrange. A 13-week study of risperidone long-acting injection compared with olanzapine found statistically significantly higher rates of extrapyramidal symptoms with risperidone (25% 53 compared with 15%; P<0. Rates of discontinuation due to these adverse events were not different between the groups. In a retrospective study of pharmacy records, new users of haloperidol, olanzapine, and risperidone were identified. Prescriptions for antiparkinson drugs taken during the first 90 days of atypical antipsychotic use were analyzed using a Cox proportional hazards model adjusting 308 for potential confounders. The analysis compared olanzapine and risperidone to haloperidol. Both drugs resulted in a lower risk for starting antiparkinson drugs even after considering prior antipsychotics and antiparkinson drug use. Although the reduction in risk was numerically greater with olanzapine, direct analysis was not conducted and the confidence intervals overlapped. Yet differences were not found on 6 other measures of extrapyramidal symptoms and higher rates of use of anticholinergic medications with higher doses of risperidone were found in another 29, 82 study. The strength of the evidence on extrapyramidal symptoms in comparisons of clozapine and risperidone was severely hampered by the dose inequities – usually higher doses 310 of risperidone (> 6 mg daily) and lower doses of clozapine than typically used. In 1 study the difference in use of anticholinergic medications at the higher but not the lower dose of risperidone supported the dose-response relationship between extrapyramidal symptoms and risperidone.
This larger decrease in A1c occurred in the glibenclamide group across strata defined by sex kamagra 100mg for sale effexor xr impotence, race kamagra 100mg with visa erectile dysfunction treatment vacuum constriction devices, age kamagra 100 mg visa impotence diabetes, baseline A1c kamagra 100mg without a prescription impotence sentence, or entry metformin dose. Comorbidities and other population characteristics Patients with impaired renal function were examined in several studies. Agrawal and 112 colleagues examined patients with renal impairment (creatinine clearance 30-80 mL/min) and found that rosiglitazone had similar effects on A1c in patients with and without renal 236 impairment. In a retrospective chart review of patients on dialysis with end stage renal disease, rosiglitazone was associated with weight gain and a decrease in hematocrit at 3-month follow-up compared with pioglitazone. Data for pioglitazone, however, were not presented, limiting conclusions that can be drawn. In a fair-quality study pooling 2 randomized controlled trials that compared rosiglitazone 118 plus metformin combined therapy with metformin monotherapy, Jones and colleagues 2 2 2 examined subgroups with body mass index < 25 kg/m , 25-30 kg/m , and >30 kg/m. They noted greater improvement in A1c with rosiglitazone 4 or 8 mg daily plus metformin than with metformin monotherapy (P=0. Weight gain 2 was noted in the obese group (body mass index > 30 kg/m ) receiving metformin plus rosiglitazone (2. Weight change was not reported for the other body mass index subgroups. Patients with diagnosed coronary artery disease were examined in 3 studies which were described above in Key Question 2, as these were the only studies that reported cardiovascular 103 outcomes. Wang and colleagues examined 70 Chinese with coronary artery disease and type 2 diabetes and noted significant improvement in A1c with rosiglitazone with change in weight similar to the to no-treatment control group. The primary and composite endpoint of coronary events (including death) was significantly decreased in the rosiglitazone group (P value reported 158 as both <0. Wang and colleagues also examined Chinese persons with metabolic syndrome and found that fasting plasma glucose did not improve significantly in either the rosiglitazone or the placebo group (A1c was not presented). At 6-month follow-up there were no significant differences in glycemic control or lipid concentrations between the 2 groups. The rate of restenosis and the stenosis diameter were less in the rosiglitazone group (between-group P=0. Thirty-one postmenopausal women were examined in a poor-quality, placebo-controlled 101 trial of rosiglitazone 4 mg daily. Results were similar to other placebo-controlled trials and no adverse events were reported. No studies explicitly examined populations with a history of hypoglycemic episodes. Nor were studies identified that examined the effect of concomitant medications on the comparative effectiveness of pioglitazone and rosiglitazone. Most studies permitted the use of a variety of antihypertensive, cardiac, and cholesterol-lowering medications among participants. Subgroup or Thiazolidinediones Page 79 of 193 Final Report Update 1 Drug Effectiveness Review Project other stratified analyses were not performed to allow examination of drug-drug interactions with the thiazolidinediones. In the updated report, we identified new data on the use of thiazolidinediones in persons with comorbidities, particularly with cardiovascular disease. Since the publication of the large 60 PROACTIVE study (discussed above) which compared pioglitazone with placebo, several additional subgroup analyses have been published, including of subjects with prior myocardial 79 80 infarction or stroke. In the subgroup of patients with a previous myocardial infarction at 79 baseline (N=2445) pioglitazone had a significant beneficial effect on fatal and nonfatal myocardial infarction (28% risk reduction, P=0. There were no significant differences between groups for cardiovascular death or nonfatal myocardial infarction, or stroke, although event rates in the pioglitazone group were consistently lower than with placebo. Rates of heart failure requiring hospitalization or fatal heart failure were not significantly different between the pioglitazone and placebo groups, but heart failure occurred in a greater proportion of patients in the myocardial infarction subgroup (11. In another prespecified subgroup analysis of the PROACTIVE trial, pioglitazone was 80 examined in subjects with (N=984) and without (N=4254) a prior stroke. In subjects with prior stroke, there was a trend towards benefit with pioglitazone for the primary composite endpoint (all-cause death, nonfatal myocardial infarction, acute coronary syndrome, and cardiac interventions, stroke, amputation above the ankle, or revascularization) (hazard ratio 0. Also in the group with prior stroke, pioglitazone reduced fatal or nonfatal stroke (hazard ratio 0. In the subgroup without prior stroke, pioglitazone did not reduce the risk of first stroke. Several other smaller recent trials also examined comorbidity subgroups with pioglitazone. In a small, open-label study in subjects with overt diabetic nephropathy (mean creatinine 2. A small, placebo- controlled pioglitazone monotherapy study in persons newly diagnosed with type 2 diabetes and 237 coronary heart disease found was no significant difference between groups in change in A1c. In a small randomized controlled trial (N=47) patients with impaired glucose tolerance or type 2 diabetes in addition to nonalcoholic steatohepatitis received either pioglitazone 45 mg 82 daily or placebo, in addition to a weight loss intervention. Glycemic control improved with pioglitazone compared with placebo (P<0. Liver aminotransferase levels normalized with pioglitazone, and plasma aspartate and alanine aminotransferase levels, along with hepatic fat content, all decreased with pioglitazone compared with placebo (P<0. Histologic changes in the liver also improved significantly with pioglitazone. In this fair-quality trial, patients were not stratified with respect to type 2 diabetes or impaired glucose tolerance status. In another small study, patients with acute coronary syndrome received pioglitazone or 93 no additional treatment starting 2 weeks after percutaneous, bare metal stent placement. Determined from quantitative angiography at 6 months, the late luminal loss was less in the pioglitazone group than in the control group (P=0. Major cardiac events (myocardial infarction or revascularization of the target lesion) were significantly decreased in the pioglitazone group at 6 months compared with the control group (7. Several studies in the updated report examined rosiglitazone with comorbidities. In a very small (N=16), poor-quality randomized controlled trial, subjects with coronary stent implantation were randomized to rosiglitazone 4-8 mg daily or placebo for 6 months. Rosiglitazone did not 108 reduce in-stent restenosis. There were no differences in cardiac events between the groups. Lautamaki and colleagues noted a decrease in A1c compared with placebo in a study of combination therapy in patients with coronary artery disease (P<0.

TZDs compared to other oral hypoglycemic agents: In a prior systematic review, there were no between-group differences between thiazolidinediones and metformin (7 randomized controlled trials) or second- generation sulfonylureas (13 randomized controlled trials). Thiazolidinedione plus metformin compared with a second-generation sulfonylurea plus metformin (2 randomized controlled trials) did not show a consistent effect favoring 1 of the combinations, nor did 2 randomized controlled trials comparing thiazolidinediones with repaglinide. One trial comparing pioglitazone to acarbose favored pioglitazone for A1c reduction.

Sedation Fair First-generation antihistamines (diphenhydramine generic kamagra 100 mg with amex erectile dysfunction treatment in tampa, chlorpheniramine) more sedating than newer-generation agents buy kamagra 100 mg fast delivery cough syrup causes erectile dysfunction. Cetirizine and levocetirizine were more sedating than loratadine and desloratadine generic 50 mg kamagra with amex erectile dysfunction protocol foods. Some evidence suggested that cetirizine may be more sedating than fexofenadine purchase 50mg kamagra free shipping impotence kidney disease. There was no significant difference in reports of sedation between loratadine and fexofenadine in 1 observational study. Headache Fair Headache was reported with similar rates in cetirizine, loratadine, and fexofenadine. Cardiac effects Fair A large, fair-quality cohort study provided evidence of a significant risk of cardiac arrhythmias with cetirizine compared with non-use. A nonsignificant increase in risk was noted with loratadine. Limited evidence suggested no QTc prolongation with loratadine and fexofenadine. Bitter taste/nasal Fair Incidence was higher with azelastine than discomfort olopatadine in head-to-head trials but indirect assessment suggested minimal difference between groups. Children No head-to-head data on adverse Insufficient evidence on comparative events except 2 events in cetirizine safety. Fair-quality evidence on the safety of cetirizine and loratadine. Limited evidence on the safety of desloratadine and fexofenadine. Fair evidence that cetirizine does not significantly prolong QTc interval. Limited evidence (1 study each) that desloratadine and fexofenadine did not prolong QTc interval. Subgroups Are there subgroups of patients based on demographics (age, racial groups, gender), concomitant medications (drug-drug interactions), co-morbidities (drug-disease interactions or pregnancy), for which one newer antihistamine is more effective or associated with fewer adverse effects? Age, gender, There was insufficient evidence to We did not identify head-to-head race/ethnicity determine whether any of the comparative studies of drug interactions. Asthma or atopic Fair There were no differences in rate of dermatitis adverse events in patients with allergic rhinitis and asthma or atopic dermatitis. Pregnancy Fair There was minimal increase risk of birth defects observed with newer antihistamines in pregnant women. Newer antihistamine drug exposure in pregnant women did not significantly increase the risk of hypospadias in male infants.
