Myofascial pain is an important yet under recognised component of cancer pain. It has a prevalence of between 11.9 and 44.8% in cancer patients. Treatments for myofascial pain reduce the prevalence of myofascial trigger points therefore decreasing pain and improving range of motion. Pridinol is a nonbenzodiazepine antispasmodic licenced for the treatment of central and peripheral muscle spasms in adults. This paper describes two case histories where patients with myofascial pain were successfully treated with pridinol. These cases highlight the importance of treating myofascial pain and the potential of pridinol to treat cancer-related myofascial pain.
