Overall cheap sildenafil 25 mg line, the incidence of adverse events was similar between medication groups; however purchase 25mg sildenafil, significantly more sertraline-treated patients discontinued due to adverse events than placebo-treated patients (P<0 purchase sildenafil 75mg with mastercard. Alzheimer’s disease/dementia Two randomized trials compared sertraline and placebo for patients with depression and 320 order sildenafil 50 mg on-line, 321 comorbid Alzheimer’s disease purchase 75 mg sildenafil amex. More patients treated with sertraline responded to treatment (full responders, 38%; partial responders, 46%) than did patients treated with placebo (full responders, 20%; partial responders, 15%) (P<0. A second fair 12-week trial which randomized 133 patients with mild-to-moderate Alzheimer’s disease and depression to either sertraline (100mg/d) or placebo did not replicate the above findings. Mood was assessed by the modified Alzheimer Disease Cooperative Study- Clinical Global Impression of Change index and the CSDD. At the end of week 12, CSDD scores and remission rates did not differ between sertraline and placebo (OR 2. Treatment with sertraline, however, was associated with more adverse events, specifically gastrointestinal adverse events than with placebo. Serious adverse events occurred in 321 20 percent of patients in the sertraline group compared with 11 percent in the placebo group. Arthritis Our searches yielded only one trial that evaluated the efficacy of an antidepressants in depressed 322 patients with comorbid arthritis. This study is a subgroup analysis of a larger placebo- 323 controlled trial in elderly patients randomized to duloxetine (60 mg/d) or placebo. The subgroup analysis analyzed 233 subjects with MDD and co-occurring arthritis, diabetes and/or vascular disease; 55 percent of patients had diabetes. There were no statistically significant treatment-by-comorbidity interactions for any comorbidity (P < 0. Results must be interpreted with caution as this was the only study addressing this topic. Cancer Fluoxetine compared with placebo 324 We detected only one trial that studied the efficacy of fluoxetine in cancer patients; however, this placebo-controlled trial failed to meet our inclusion criteria because the duration of the study was less than 6 weeks. We mention it here because it was the only trial on this topic. This 5- week trial studied the efficacy of fluoxetine in 91 cancer patients with depression or adjustment disorder. The majority of the patients were female; 13 percent in the fluoxetine group and 5 percent in the placebo group had metastatic disease. Efficacy according to the main, observer-rated outcome measures (HADS, MADRS, HAS) did not differ significantly between the active drug and placebo groups. Improvements were generally greater in the fluoxetine group but statistically significant only for the SCL90-R (33% compared with 15%; P=0. No statistically significant difference in quality of life was reported. However, study duration was short and a substantially greater percentage of patients in the fluoxetine group had a more advanced stage of cancer at baseline. Fluoxetine-treated patients had a significantly greater drop-out rate than placebo-treated patients (33% compared with 15%; P=0. Paroxetine compared with placebo A 6-week randomized trial compared paroxetine (20 mg/d) and placebo in depressed breast cancer patients who were receiving at least four cycles of chemotherapy to evaluate whether the 325 use of an antidepressant can alleviate symptoms of depression and reduce fatigue. Although Second-generation antidepressants 99 of 190 Final Update 5 Report Drug Effectiveness Review Project this study was rated poor because of lack of ITT analysis and inadequate description of study duration, we included it because it was the only study conducted in cancer patients that satisfied our inclusion criteria. Paroxetine was more effective in reducing depression during chemotherapy, as measured by the Center for Epidemiological Studies of Depression (CES-D) (P=0. No differences between treatment groups were apparent with respect to fatigue. Diabetes Our searches yielded two trials that evaluated the efficacy of an antidepressants in depressed 322, 326 patients with comorbid diabetes. One fair-rated study randomized 89 depressed, low- income Hispanics and African Americans with diabetes to sertraline (50-100 mg/day) or placebo 326 for 6 months. HAM-D scores decreased significantly in both groups but there was no significant difference between sertraline-treated and placebo-treated patients. Quality of life measures improved significantly in both groups, but no difference was found between groups.

Within the hierarchy of observational studies generic sildenafil 75mg online, well-conducted cohort designs are preferred for assessing a common outcome purchase sildenafil 100mg without prescription. Case-control studies are preferred only when the outcome measure is rare and the study is well conducted discount sildenafil 50mg on-line. Systematic reviews pay particular attention to whether results of efficacy studies can be generalized to broader applications best sildenafil 75 mg. Efficacy studies provide the best information about how a drug performs in a controlled setting sildenafil 75mg cheap. These studies attempt to tightly control potential confounding factors and bias; however, for this reason the results of efficacy studies may not be applicable to many, and sometimes to most, patients seen in everyday practice. Most efficacy studies use strict eligibility criteria that may exclude patients based on their age, sex, adherence to treatment, or severity of illness. For many drug classes, including the antipsychotics, unstable or severely impaired patients are often excluded from trials. In addition, efficacy studies frequently exclude patients who have comorbid disease, meaning disease other than the one under study. Efficacy studies may also use dosing regimens and follow-up protocols that are impractical in typical practice settings. These studies often restrict options that are of value in actual practice, such as combination therapies and switching to other drugs. Efficacy studies also often examine the short-term effects of drugs that in practice are used for much longer periods. Finally, efficacy studies tend to assess effects by using objective measures that do not capture all of the benefits and harms of a drug or do not reflect the outcomes that are most important to patients and their families. Systematic reviews highlight studies that reflect actual clinical effectiveness in unselected patients and community practice settings. Effectiveness studies conducted in primary care or office-based settings use less stringent eligibility criteria, more often assess health outcomes, and have longer follow-up periods than most efficacy studies. The results of effectiveness studies are more applicable to the “average” patient than results from the highly selected populations in efficacy studies. Examples of effectiveness outcomes include quality of life, frequency or duration of hospitalizations, social function, and the ability to work. These outcomes are more important to patients, family, and care providers than surrogate or intermediate measures, such as scores based on psychometric scales. For example, a study might use very narrow inclusion criteria like an efficacy study, but, like an effectiveness study, might examine flexible dosing regimens, have a long follow-up period, and measure quality of life and functional outcomes. For this report we sought evidence about outcomes that are important to patients and would normally be considered appropriate for an effectiveness study. However, many of the studies that reported these outcomes were short-term and used strict inclusion criteria to select eligible patients. For these reasons, it was neither possible nor desirable to exclude evidence based on these characteristics. Labeling a study as either an efficacy or an effectiveness study, although convenient, is of limited value; it is more useful to consider whether the patient Statins Page 10 of 128 Final Report Update 5 Drug Effectiveness Review Project population, interventions, time frame, and outcomes are relevant to one’s practice or to a particular patient. Studies anywhere on the continuum from efficacy to effectiveness can be useful in comparing the clinical value of different drugs. Effectiveness studies are more applicable to practice, but efficacy studies are a useful scientific standard for determining whether characteristics of different drugs are related to their effects on disease. Systematic reviews thoroughly cover the efficacy data in order to ensure that decision makers can assess the scope, quality, and relevance of the available data. This thoroughness is not intended to obscure the fact that efficacy data, no matter how large the quantity, may have limited applicability to practice. Clinicians can judge the relevance of studies’ results to their practice and should note where there are gaps in the available scientific information. Unfortunately, for many drugs there exist few or no effectiveness studies and many efficacy studies. Yet clinicians must decide on treatment for patients who would not have been included in controlled trials and for whom the effectiveness and tolerability of the different drugs are uncertain.
