Evidence-based review of clinical studies on pharmacology (non-anesthetic studies).

We have divided the analysis of pharmacology studies into studies on local anesthetics and studies on all other pharmacologic agents. This division reflects the large number of studies focusing on methods for obtaining effective anesthesia in patients and permits an independent focus on those clinical studies evaluating nonanesthetic drugs. In this section, we review that alternative class of agents, with an emphasis this year on clinical studies evaluating oral analgesics.
