Analysis of Analgesic Trials

  • Chapter

Abstract

Analgesic clinical trials are usually complex. Because of the complexity of these trials knowledge of pharmacokinetic/pharmacodynamic relationships of analgesics is limited. The consequence of this is that some recommended analgesic doses may not be optimal. The design of an analgesic clinical trial is usually of the following pattern; patients receive a single dose of an analgesic or a placebo after a pain-initiating event such as surgery, and pain intensity or pain relief is measured to assess drug efficacy at specific times after drug administration. On ethical grounds, the patients can demand a rescue medication of a known effective analgesic at any time if their pain relief is inadequate. Pain relief and remedication time—two clinical efficacy endpoints—are compared between placebo and the administered active doses of the analgesic tested.
