  • Patent number: 4533551
    Abstract: The effect of prolonged treatment with etodolac on the articular pathology associated with adjuvant arthritis in the rat has been compared to the effects produced by similar treatment with naproxen and ibuprofen. Drug effects were assessed by radiologic and histopathologic examinations. The effects on hindpaw edema, hindleg function, and body weight gain were also evaluated. Treatment was initiated on day 16 after adjuvant injection and continued for 28, 56 or 84 days. The degree of relapse which occurred during 28 days of non-treatment after dosage was stopped after 28 or 56 days of treatment was also assessed. Etodolac prevented the progression of the disease. Further, it appeared to diminish the severity of the articular lesions already present on day 16 before drug treatment began. All the parameters measured were improved and there was good agreement between the radiologic and histopathologic assessments of articular damage.
