Renal clearance in rheumatoid arthritis RA patients taking PLAQUENIL for at least six months seemed to be similar to that of the single dose studies in volunteers, suggesting that no change occurs with chronic dosing. Range for renal clearance of unchanged drug was approximately 16 to 30% and did not correlate with creatinine. A small retrospective study on 118 patients with rheumatoid arthritis reported that 55% of patients receiving chloroquine and 15% of those receiving hydroxychloroquine showed a 10% decrease of creatinine clearance after the start of antimalarial drugs.
