Study Evaluating Heated Lidocaine/Tetracaine Patch in Patients With Pain Associated With Myofascial Trigger Points

The purpose of this pilot study is to explore the usefulness of a heated lidocaine 70 mg and
tetracaine 70 mg topical patch for the treatment of pain associated with myofascial trigger
points. The study will consist of a 2-week, open-label treatment period followed by a 2
week follow-up period conducted at a single study site. Eligible patients must have a
clinical diagnosis of pain (minimum 1-month duration) associated with up to 3 identifiable
myofascial trigger points. A number of efficacy variables will be employed to evaluate their
utility for assessing painful responses in this population.
