Key Insights from Trials
- Topical formulations (gels, patches) demonstrate comparable efficacy to oral preparations with fewer systemic adverse effects, improving patient compliance.
- Combination therapies with Diclofenac (e.g., with gastroprotective agents) are being explored for gastrointestinal safety.
- New delivery systems (microemulsions, long-acting patches) show promising pharmacokinetic profiles.
- Safety signals remain consistent; gastrointestinal (GI) adverse events (AEs), cardiovascular (CV) risks, and hepatic effects continue to be monitored.
Regulatory Developments & Market Approvals
- FDA approved Diclofenac Sodium Topical Gel (0.1%) for osteoarthritis pain in knees in 2022 [1].
- EMA recently approved Diclofenac Liposome Formulation for localized musculoskeletal pain, emphasizing improved targeting with reduced systemic exposure [2].
