Meta AnalysisMeta-analysis comparing newer antipsychotic drugs for the treatment of schizophrenia: evaluating the indirect approach.
Meta-analysis is a useful method to assess the efficacy of newer antipsychotic drugs compared with older drugs or placebo. However, few trials directly compare novel drugs to each other. ⋯ An indirect meta-analysis of studies comparing olanzapine with haloperidol and risperidone with haloperidol yielded conclusions similar to those found in a direct comparative RCT of olanzapine and risperidone.

Meta Analysis Comparative StudyAdverse events and treatment discontinuations in clinical trials of fluoxetine in major depressive disorder: an updated meta-analysis.
A 1993 meta-analysis of US Investigational New Drug clinical trials of fluoxetine reinforced this agent's more favorable adverse-event profile compared with tricyclic antidepressants (TCAs). ⋯ Data from this large series of clinical trials confirm that fluoxetine is well tolerated in the acute treatment of MDD in adults, especially at a dosage of 20 mg/d, and is better tolerated than the recommended doses of TCAs.

The safety of naproxen sodium for over-the-counter use was evaluated based on 48 randomized, double-blind, placebo-controlled clinical trials that evaluated naproxen/naproxen sodium (NAP) for indications appropriate to, and under, conditions common to, nonprescription analgesics. Of the 48 studies, 27 were single-dose studies and 21 were multiple-dose studies of 1 to 10 days' duration; 19 studies included ibuprofen and 9 included acetaminophen. A total of 4138 patients received naproxen or naproxen sodium (3589 patients received naproxen 187.5 to 400 mg and 549 received naproxen sodium 220 to 440 mg), 2423 received placebo, 1574 received ibuprofen (200 or 400 mg), and 671 received acetaminophen (500 to 1000 mg). ⋯ Across all 48 studies, 83% of both the NAP- and placebo-treated patients reported no adverse events. The incidence rates were similar between NAP and placebo, with headache (4.8% NAP, 6.4% placebo), nausea (3.4% NAP, 3.1% placebo), and somnolence (2.7% NAP, 1.9% placebo) the most commonly reported events. Rates of adverse events with NAP, ibuprofen, and acetaminophen were similar.
