Diclofenac sodium topical gel 1%, a nonsteroidal anti-inflammatory drug (NSAID), has emerged as a widely used treatment option for relieving pain and inflammation associated with various musculoskeletal conditions. As a topical formulation, it offers a localized approach to pain management, reducing the risk of systemic side effects commonly associated with oral NSAIDs.
Efficacy of Diclofenac Sodium Topical Gel 1% in Pain Relief
The efficacy of diclofenac sodium topical gel 1% in pain relief has been extensively studied in clinical trials. A study published in the Journal of Pain Research demonstrated that diclofenac sodium gel significantly reduced pain intensity and improved functional ability in patients with osteoarthritis of the knee. The study reported a mean reduction in pain intensity of 30.4% after 4 weeks of treatment, compared to 11.4% in the placebo group.
Mechanism of Action
Diclofenac sodium topical gel 1% works by inhibiting the production of prostaglandins, which are hormone-like substances that cause pain and inflammation in the body. By blocking the enzyme cyclooxygenase (COX), diclofenac reduces the synthesis of prostaglandins, thereby decreasing inflammation and pain.
