Abstract
Objective: Previous studies have shown that fenofibrate therapy increases serum creatinine level and that there is a return of serum creatinine to baseline level after the discontinuation of the drug. We evaluated the effect of long-term fenofibrate therapy on creatinine levels and its reversibility in patients with hypertension and hypertriglyceridemia.

Methods: This retrospective study enrolled 54 hypertensive and hypertriglyceridemic patients taking fenofibrate for 3?6 years (Fenofibrate group) and 30 control patients with similar age, sex, follow-up duration, and creatinine levels (Control group). In 23 patients taking fenofibrate with low triglyceride level and/or with high creatinine levels, fenofibrate was discontinued, and creatinine levels were measured after 2 months.

Results: Creatinine levels increased in both the fenofibrate group (from 0.91¡¾0.18 mg/dL to 1.09¡¾0.23 mg/dL, p<0.001) and the control group (from 0.94¡¾0.16 mg/dL to 0.98¡¾0.16 mg/dL, p=0.04) compared to baseline. However, the elevation was more pronounced in the fenofibrate group than in the control group (21.1¡¾15.4% vs. 4.5¡¾11.3%, p<0.001). The discontinuation of fenofibrate lowered creatinine levels (from 1.39¡¾0.32 mg/dL to 1.15¡¾0.24 mg/dL, p<0.001) which were still higher than pre-treatment levels (p=0.013).

Conclusion: Long-term fenofibrate therapy significantly increased creatinine levels in hypertensive and hypertriglyceridemic patients. The effect of fenofibrate on creatinine level was partially reversible. This finding suggests that follow-up creatinine level is necessary with fenofibrate therapy.
