Atypical antipsychotic drugs Page 48 of 230 Final Report Update 3 Drug Effectiveness Review Project For olanzapine, these results compared with the results of CATIE Phase 1 as shown in Table 4, below. In comparing olanzapine with ziprasidone, the mixed-treatment comparisons analysis found a larger magnitude of effect favoring olanzapine than CATIE found. In CATIE Phase 1, risperidone, immediate-release quetiapine, and ziprasidone were not statistically significantly different from each other. Olanzapine was also found to have lower rates of discontinuations due to lack of efficacy or patient decision, and significantly longer duration of successful treatment than immediate-release quetiapine. The numbers needed to treat with olanzapine for discontinuation due to lack of efficacy were 7. A statistically significant difference was not found between risperidone and quetiapine or between risperidone and ziprasidone for either lack of efficacy or due to the patient’s decision.

An analysis of 31 trials directly comparing olanzapine with risperidone is represented in Figure 4, below. The graph indicates that olanzapine had lower rates of early discontinuation of drug compared with risperidone. This group of studies represented the largest body of direct comparison evidence in this report.

Overall, the findings of these studies were consistent with the trials in that clozapine was found to have lower discontinuation rates than other atypical antipsychotic drugs and olanzapine was found to have lower rates than the rest of the atypical antipsychotic drugs, with few exceptions. New evidence on risperidone long-acting injection indicated that oral atypical antipsychotics may have lower rates of discontinuation over longer periods of follow-up (18 months). Findings were also consistent that olanzapine resulted in a longer time to discontinuation compared with other antipsychotics, with the exception of clozapine. Clozapine was found to have a lower discontinuation rate than other atypical antipsychotics studied (olanzapine, immediate-release quetiapine, risperidone, risperidone long- 203, 212, 247 acting injection). Of 10 studies comparing olanzapine with risperidone, 6 found the rate 166, 169, 175, 176, 218, 247 of discontinuation lower with olanzapine, while the others did not find a 181, 197, 204, 212 statistically significant difference. Olanzapine was not found to have statistically significantly different rates of discontinuation compared with aripiprazole or ziprasidone in a 204 study of Maryland Medicaid data. Immediate-release quetiapine was found to have higher 204, 218, 247 rates of discontinuation than olanzapine in 3 of 4 studies, and no difference was found Atypical antipsychotic drugs Page 50 of 230 Final Report Update 3 Drug Effectiveness Review Project 210 compared with aripiprazole in a single study. Risperidone long-acting injection was studied in a large study of United States Veterans (N=11 821), where the injection was found to have higher rates of discontinuation over an 18-month follow-up period compared with aripiprazole, clozapine, olanzapine, immediate-release quetiapine, and risperidone (oral), but no difference 203 with ziprasidone. In a small study of electronic medical records of patients in a Scottish 210 county, aripiprazole and quetiapine discontinuation rates were similar.

Atypical antipsychotic drugs Page 52 of 230 Final Report Update 3 Drug Effectiveness Review Project Time to discontinuation In CATIE Phase 1, time to discontinuation for any reason was significantly longer with olanzapine than risperidone (hazard ratio, 0. Although differences among risperidone, immediate-release quetiapine, and ziprasidone were found to be statistically significant, the clinical significance was limited, as the Kaplan-Meier analysis of time to discontinuation for the 3 drugs was 4. Olanzapine was also found to have a significantly longer duration of successful treatment (hazard ratio, 0. Successful treatment was defined as CGI-S score of at least 3 (mildly ill) or by a score of 4 (moderately ill) with an improvement of at least 2 points from baseline. The duration of successful treatment was significantly longer in the risperidone group than in the immediate-release quetiapine group (hazard ratio, 0. Time to discontinuation due to lack of efficacy was statistically significantly longer for olanzapine compared with immediate- release quetiapine (hazard ratio, 0.

Standard error (SE): A measure of the variation in the sample statistic over all possible samples of the same size ponstel 250 mg fast delivery muscle relaxant intravenous. The standard error decreases as the sample size increases purchase ponstel 500mg without prescription muscle relaxant tramadol. Standard treatment: The treatment or procedure that is most commonly used to treat a disease or condition. In clinical trials, new or experimental treatments sometimes are compared to standard treatments to measure whether the new treatment is better. Statistically significant: A result that is unlikely to have happened by chance. Study: A research process in which information is recorded for a group of people. The data are used to answer questions about a health care problem. Study population: The group of people participating in a clinical research study. The study population often includes people with a particular problem or disease. It may also include people who have no known diseases. Subgroup analysis: An analysis in which an intervention is evaluated in a defined subset of the participants in a trial, such as all females or adults older than 65 years. Superiority trial: A trial designed to test whether one intervention is superior to another. Surrogate outcome: Outcome measures that are not of direct practical importance but are believed to reflect outcomes that are important; for example, blood pressure is not directly important to patients but it is often used as an outcome in clinical trials because it is a risk factor for stroke and heart attacks. Surrogate endpoints are often physiological or biochemical markers that can be relatively quickly and easily measured, and that are taken as being predictive of important clinical outcomes. They are often used when observation of clinical outcomes requires long follow-up. Long-acting opioid analgesics 53 of 74 Final Update 6 Report Drug Effectiveness Review Project Survival analysis: Analysis of data that correspond to the time from a well-defined time origin until the occurrence of some particular event or end-point; same as time-to-event analysis. Systematic review: A review of a clearly formulated question that uses systematic and explicit methods to identify, select, and critically appraise relevant research and to collect and analyze data from the studies that are included in the review. The extent to which a drug’s adverse effects impact the patient’s ability or willingness to continue taking the drug as prescribed. These adverse effects are often referred to as nuisance side effects, because they are generally considered to not have long-term effects but can seriously impact compliance and adherence to a medication regimen. Treatment regimen: The magnitude of effect of a treatment versus no treatment or placebo; similar to “effect size”. Can be calculated in terms of relative risk (or risk ratio), odds ratio, or risk difference. Two-tailed test (two-sided test): A hypothesis test in which the values that reject the null hypothesis are located in both tails of the probability distribution. For example, testing whether one treatment is different than another (rather than testing whether one treatment is either better than another). Type I error: A conclusion that there is evidence that a treatment works, when it actually does not work (false-positive). Type II error: A conclusion that there is no evidence that a treatment works, when it actually does work (false-negative). Validity: The degree to which a result (of a measurement or study) is likely to be true and free of bias (systematic errors). Variable: A measurable attribute that varies over time or between individuals. Variables can be • Discrete: taking values from a finite set of possible values (e.

Opportunistic Infections (OIs) 351 Candidiasis Candidiasis is an infection with yeast-forming fungi. Of the 150 Candida species known to date, only approximately 20 cause disease. Although it was commonly assumed that azole resistance is a problem particularly with albicans strains, this has not been the case to date (Sanglard 2002). Candidiasis is an important indicator of immunodeficiency and should be seen as a reason to consider starting ART, even with good immune status. Esophageal candidiasis and even oral thrush often occur following other OIs. Fever, not a classic symptom of candidiasis, is a particular indication to be on the alert for. If immune status is good, it must be remembered that there are also other reasons for thrush – alcoholism and steroid treatment are only two of many possibilities. In addition to candidiasis of the oropharynx and esophagus, vaginitis is a frequent problem in women (also occurring in healthy individuals). Candidemia occurs only rarely in HIV+ patients, even with severe immunodeficiency. Signs and symptoms The oropharynx is usually affected, with taste disturbances and sometimes a burning sensation on the tongue. White, non-adherent plaques on the buccal mucosa, tonsillar ring and tongue confirm the diagnosis. Occasionally, there may be atrophic candidiasis, which presents only with an erythematous mucosa. Candida esophagitis usually occurs with oropharyngeal involvement, but in about one third of cases there is no oral thrush. It often presents with dysphagia (“drink- ing is ok, but food can’t go down”) and retrosternal pain. Some patients complain of nausea, although vomiting occurs only rarely. Diagnosis Diagnosis in the oropharynx can be made based on clinical appearance. Characterization by culture or even determination of drug sus- ceptibility (beware laboratory uncertainty! Oral candidiasis is not to be confused with oral hairy leukoplakia (OHL). In contrast to candidiasis, the whitish, hairy plaques of OHL, on the sides of the tongue, cannot be scraped off. OHL is not caused by fungi but by EBV, and is an important disease marker for HIV, even if it is harm- less and does not require treatment.
