Exploratory Study on the Use of Pregabalin for the Treatment of Taxol Related Arthralgia-Myalgia

Paclitaxel is chemotherapeutic agent used in many of the most common anti-cancer regimens. Its use is frequently associated with moderate to severe muscle and joint pain that may persist for several days after the treatment. This side effect, known as "Arthralgia-Myalgia Syndrome, has a significant impact on the quality of life and functional abilities of those receiving the treatment, and is not alleviated by many of the interventions attempted for that purpose. Sporadic reports suggest that a drug called gabapentin may be effective in the management of this adverse effect. Observations from our practice indicate that pregabalin, which possesses similar biological activity to that of gabapentin, may also be useful in preventing and treating paclitaxel associated myalgia - arthralgia. The current study represents an initial evaluation of the hypothesis that pregabalin may be beneficial in the management of the symptoms due to the "Arthralgia-Myalgia Syndrome". The investigation will be carried out in the format of a small scale, randomized, placebo controlled trial with patients receiving paclitaxel in the course of standard treatment for breast cancer.
