Efficacy and Absorption Considerations
- Diclofenac gel has shown significant efficacy in both younger (25-64 years) and older (≥65 years) patients with knee osteoarthritis 3
- Percutaneous absorption of diclofenac from topical formulations is approximately 3-6% of the applied dose 4
- Steady-state levels in muscle tissue near the application site can be about 3 times higher than in distant muscle tissue, indicating targeted delivery 4
Potential Adverse Effects
- Most common: application site reactions including dermatitis (4-6% of patients) 3
- Although systemic absorption is limited, rare cases of gastrointestinal hemorrhage have been reported with frequent application (three times daily for extended periods) 5
- Gastrointestinal adverse events are generally infrequent with topical diclofenac compared to oral NSAIDs 3
Important Considerations for Specific Populations
- Elderly patients (≥65 years) show similar efficacy and safety profiles to younger patients when using diclofenac gel 3
- No dosage adjustments are typically required based on age, hepatic function, or presence of rheumatoid arthritis 6
Remember to use the lowest effective dosage for the shortest duration consistent with individual treatment goals to minimize potential adverse effects.
