Methotrexate off the hook? no lung harm found in RA study
NCT ID NCT07360340
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at 50 Egyptian patients with rheumatoid arthritis to see if methotrexate affects lung health. Half were taking methotrexate, and half were on other treatments. Researchers used lung function tests and CT scans to check for lung disease. They found no difference between the two groups, suggesting methotrexate may not cause lung problems in these patients.
