Evaluation of the Depth and Duration of Anesthesia From Heated Lidocaine/Tetracaine (Synera®) Patches Compared With 5% Lidocaine (Lidoderm®) Patches Applied to Healthy Adult Volunteers
January 2, 2013 updated by: CRI Lifetree
This will be a randomized, single-blind, active-controlled, two-period crossover study in adult volunteers to compare the duration and depth of anesthesia between Synera® and Lidoderm® patches when applied for 30 minutes and 4 hours.
The study will include a Screening Visit, two Treatment Periods, and a Follow-Up Phone Contact.

- Subject is willing to refrain from using any local topical preparations on the volar aspect of the forearms for 24 hours prior to each site visit.
- Subject has normal, intact skin bilaterally at the antecubital area.
If female, must be of non-childbearing potential (defined as postmenopausal for at least 1 year or surgically sterile [bilateral tubal ligation, bilateral oophorectomy or hysterectomy]) or must be using adequate contraception (practicing one of the following methods of birth control):
