Mefenamic acid compared with ibuprofen in the treatment of rheumatoid arthritis

Area of Science:

• Rheumatology
• Pharmacology
• Clinical Medicine

Background:

• Rheumatoid arthritis (RA) is a chronic autoimmune disease causing joint inflammation and pain.
• Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used for RA symptom management.
• Mefenamic acid and ibuprofen are widely prescribed NSAIDs.

Purpose of the Study:

• To compare the efficacy and safety of mefenamic acid and ibuprofen in patients with rheumatoid arthritis.
• To evaluate the analgesic and anti-inflammatory properties of both drugs within a within-patient study design.

Main Methods:

• A randomized, double-blind, within-patient study was conducted.
• Forty patients diagnosed with rheumatoid arthritis participated in the trial.
• Mefenamic acid was compared directly against ibuprofen.

Main Results:

• Both mefenamic acid and ibuprofen demonstrated significant analgesic and anti-inflammatory effects.
• No statistically significant difference in efficacy was observed between the two drugs at the dosages used.
• Side effects were similar, with drowsiness reported by six patients on ibuprofen and two on mefenamic acid.

Conclusions:

• Mefenamic acid and ibuprofen are equally effective for managing pain and inflammation in rheumatoid arthritis.
• The safety profiles of mefenamic acid and ibuprofen are comparable in this patient population.
• Further research may explore optimal dosing and long-term effects.
