Although the efficacy of clopidogrel plus aspirin for treating acute coronary syndromes (ACS) is well established, considerable uncertainty remains about dosing.
Investigators for the manufacturer-sponsored CURRENT–OASIS 7 trial employed a 2×2 factorial design to examine the effects of doubling the standard loading dose and first-week
maintenance dose of clopidogrel (from 300 to 600 mg and from 75 to 150 mg, respectively), and compared the effects of high-dose (300–325 mg/day) versus low-dose (75–100 mg/day)
aspirin. All 25,086 patients (mean age, 61; 27% women) had ACS and were scheduled for coronary angiography with percutaneous coronary intervention (PCI) as indicated within 72 hours after
randomization, and all received a loading aspirin dose of >300 mg. The primary 30-day outcome was a composite of cardiovascular death, myocardial infarction (MI), and stroke. The study had
80% power to detect a 16% reduction in risk.

The FDA approved a dose of dabigatran of 150 mg twice a day for use in patients with nonvalvular AF. In the pivotal RE-LY (Randomized Evaluation of Long-term
Anticoagulant Therapy) study, this dose was found to be superior to warfarin for the prevention of stroke and systemic emboli.

Conclusions Tricyclic antidepressants are effective in preventing migraine and tension-type headaches and are more effective than selective serotonin reuptake
inhibitors, although with greater adverse effects. The effectiveness of tricyclics seems to increase over time.

Abstract and Introduction
Abstract
Generalized anxiety disorder (GAD) is a common, chronic mental illness that has a significant burden on the patient's quality of life. Treatment for GAD
routinely consists of monotherapy with a proven anxiolytic such as an antidepressant or benzodiazepine, but many patients do not respond fully to these drugs, and additional
treatment may be needed. Therefore, we reviewed the safety and efficacy of atypical antipsychotics as adjunct therapy to standard GAD pharmacotherapy in patients deemed
treatment resistant. We performed a literature search of the MEDLINE database for English-language articles published from January 1966–May 2009. Identified articles
were evaluated, and only open-label trials and randomized controlled trials (RCTs) were included in the review. Relevant references from the articles were also evaluated. Only
a few reports of large-scale RCTs that assessed an atypical antipsychotic for treatment-resistant GAD have been published. Articles were found for five of the eight currently
available atypical antipsychotics, but not for asenapine, clozapine, and paliperidone. Several open-label trials and smaller RCTs support the need for further evaluation of
aripiprazole and quetiapine for treatment-refractory GAD, although one quetiapine trial demonstrated negative results. There is disparate data for risperidone, with one
open-label trial and one small RCT showing positive results and one large RCT showing negative results. One open-label trial of ziprasidone and one RCT of olanzapine both
showed beneficial effects of the drugs. Adverse effects were specific to each agent, with weight gain being the most common, but many studies did not monitor systematically
for lipid level, weight, or glucose level changes. Although data suggest efficacy regarding the use of atypical antipsychotics for augmentation of treatment-refractory GAD,
more rigorous studies (large, double-blind, placebo-controlled trials) on the safety and efficacy of these agents are needed in order to recommend their use in patients with
GAD.
