Voltaren Gel is the first prescription topical treatment for osteoarthritis that has been approved by the U.S. Food and Drug Administration. Voltaren Gel -- a nonsteroidal anti-inflammatory drug or NSAID -- in topical form, will mostly be used on knees and hands. Voltaren Gel delivers effective pain relief and has a favorable safety profile. The systemic absorption of Voltaren Gel (1 percent diclofenac sodium in topical gel formulation) is 94 percent less than oral diclofenac (generic for Voltaren).
The FDA approval of Voltaren Gel was based on several studies, including two randomized, double-blind, placebo-controlled efficacy (such as to test effectiveness) studies and a 12-month safety study.

After 6 weeks of treatment in an efficacy study of patients with hand osteoarthritis, pain levels were reduced by 46 percent. In a 12-week study of patients with knee osteoarthritis, Voltaren Gel reduced pain levels by 51 percent.
