Efficacy of Etoricoxib on Peripheral Hyperalgesia

2014-08-27 03:15:10 | BioPortfolio

Summary

The purpose of the study is to determine the efficacy of etoricoxib on pain patients. The investigators assume that patients with neuropathic pain will have greater pain relief then patients on placebo.

Description

Animal experiments analysing anti-hyperalgesic effects of Coxibs show inconsistent results due to different used dosages and varying different pain models. Theoretical the use of NSAIDs is rational, particularly of Coxibs as a part of the neuropathic pain management. But in the newest topical review, there is no valid information available about the effectiveness of these drugs in human neuropathic pain models or in patients with different underlying mechanism, e.g. with or without hyperalgesia.

Medical and Biotech [MESH] Definitions

Misunderstanding among individuals, frequently research subjects, of scientific methods such as randomization and placebo controls.

An effect usually, but not necessarily, beneficial that is attributable to an expectation that the regimen will have an effect, i.e., the effect is due to the power of suggestion.

A complex regional pain syndrome characterized by burning pain and marked sensitivity to touch (HYPERESTHESIA) in the distribution of an injured peripheral nerve. Autonomic dysfunction in the form of sudomotor (i.e., sympathetic innervation to sweat glands), vasomotor, and trophic skin changes may also occur. (Adams et al., Principles of Neurology, 6th ed, p1359)

Conditions characterized by pain involving an extremity or other body region, HYPERESTHESIA, and localized autonomic dysfunction following injury to soft tissue or nerve. The pain is usually associated with ERYTHEMA; SKIN TEMPERATURE changes, abnormal sudomotor activity (i.e., changes in sweating due to altered sympathetic innervation) or edema. The degree of pain and other manifestations is out of proportion to that expected from the inciting event. Two subtypes of this condition have been described: type I; (REFLEX SYMPATHETIC DYSTROPHY) and type II; (CAUSALGIA). (From Pain 1995 Oct;63(1):127-33)
