[Treatment of rheumatoid arthritis with isoprinosine. Personal experience].

Twenty patients with classical or proved rheumatoid arthritis were treated with Isoprinosine. 13 patients received a dose of 25 mg/kg/day and 7 received a dose of 50 mg/kg/day, continuously for 2 months and then discontinuously, 5 days every fortnight. The series being treated with 25 mg/kg/day (7 patients) have received treatment for 12 months. No side effects have been observed; the only reason for ceasing treatment was its ineffectiveness (after at least 3 months of administration). The dosage of the associated anti-inflammatory drugs did not need to be increased, but neither was it decreased. The authors conclude that Isoprinosine is largely ineffective clinically, on laboratory tests and in terms of immunology, at least with the therapeutic protocols tested here.
