Randomized Controlled Trial
Incidence and costs of polypharmacy: data from a randomized, double-blind, placebo-controlled study of risperidone and quetiapine in patients with schizophrenia or schizoaffective disorder.
The use of adjunctive psychotropics and the costs of polypharmacy in patients randomized to receive risperidone or quetiapine were compared in a placebo-controlled double-blind study conducted in India, Romania, and the United States. ⋯ The results confirm earlier reports of higher rates of polypharmacy with quetiapine than with risperidone. The findings also reveal substantial between-treatment differences in costs associated with polypharmacy. Limitations of the study include that the study was of short duration and that a high proportion of patients were recruited from countries other than the United States.

Randomized Controlled Trial Multicenter Study
A trial of levofloxacin 750 mg once daily for 5 days versus ciprofloxacin 400 mg and/or 500 mg twice daily for 10 days in the treatment of acute pyelonephritis.
A double-blind, noninferiority trial was conducted to establish the safety and efficacy of a once-daily, 5-day course of levofloxacin 750 mg compared to a twice-daily, 10-day course of ciprofloxacin in complicated urinary tract infections (cUTI) and acute pyelonephritis (AP). This report focuses on subjects with AP. ⋯ High-dose, short-course therapy with levofloxacin in subjects with AP is at least as effective as standard 10-day therapy with ciprofloxacin.
