Clofibrate treatment for hyperlipoproteinemia may cause impotence in some patients. Symptoms improved after stopping the drug, but recurred upon re-administration in one case.
Area of Science:
- Cardiology
- Endocrinology
- Pharmacology
Background:
- Type IV hyperlipoproteinemia is a lipid disorder requiring management.
- Clofibrate is a medication used to treat hyperlipoproteinemia.
- Cardiovascular risk factors, including hyperlipidemia and prior myocardial infarction, are significant.
Purpose of the Study:
- To investigate the potential link between clofibrate therapy and impotence.
- To assess the reversibility of impotence after clofibrate discontinuation.
Main Methods:
- Observational case series involving three patients with Type IV hyperlipoproteinemia.
- Monitoring of sexual function in patients undergoing clofibrate treatment.
- Interruption and re-initiation of clofibrate therapy to evaluate symptom changes.
Main Results:
- Three patients developed impotence within one year of starting clofibrate.
- Two patients experienced symptom improvement within 3-4 weeks of drug cessation.
- Impotence recurred in one patient upon resuming clofibrate therapy.
Conclusions:
- Clofibrate may be associated with the development of impotence in patients with Type IV hyperlipoproteinemia.
- The observed impotence appears to be reversible upon discontinuation of clofibrate.
- Further investigation into the mechanism and prevalence of this side effect is warranted.
Abstract:
Three of our regularly controlled patients suffering from Type IV hyperlipoproteinemia and treated with clofibrate complained of impotence within one year after commencement of treatment with this drug. Two of the patients had previously suffered from myocardial infarction. Two patients observed improvement of the symptom 3 and 4 weeks after interruption of clofibrate therapy; one patient again complained of impotence when clofibrate therapy was resumed. The third patient continued intake of the drug up to the present day, and still complains of impotence.
