title: Fibrate therapy and renal function.
abstract: Fibrates are a class of lipid-lowering medications primarily used as second-line agents behind statins. The adverse-effect profile of fibrates has been marked by a puzzling yet reversible rise in serum creatinine values with their use. It is not known whether this finding represents a true change in renal function. One proposed explanation for this phenomenon is that fibrates increase the production of creatinine, in which case a rise in serum creatinine values would not represent a true deterioration in renal function. An alternative theory is that fibrates reduce the production of vasodilatory prostaglandins, which would lead to a true change in renal function in patients who experience a rise in serum creatinine values. Routine serum creatinine monitoring is advisable in fibrate-treated patients, particularly in those with preexisting renal disease. A 30% increase in serum creatinine values in the absence of other causes of serum creatinine change warrants discontinuation of fibrate therapy. Serum creatinine values can take several weeks to return to their baseline values following discontinuation of a fibrate.
