CKS is no longer commissioned by the National Institute for Health and Clinical Excellence (NICE). NICE remains committed to providing a replacement service for CKS and is currently reviewing its options. In the meantime, although CKS content is now not being maintained, it still remains relevant and will continue to be made available. CKS content was generated under a programme of topic creation and update.

Lipid modification - primary and secondary CVD prevention - Management
When should fibrates be prescribed?
- For primary and secondary prevention of cardiovascular disease, fibrates should only be used when a statin is not tolerated.
- Fibrates should only be considered as first-line therapy in people with isolated severe hypertriglyceridaemia.
- Combination therapy with a statin and a fibrate should be only initiated under specialist advice.
Basis for recommendation
- These recommendations are based on guidance issued by the National Institute for Health and Clinical Excellence (NICE) [National Collaborating Centre for Primary Care, 2008a; NICE, 2008a] and jointly by the Medicines and Healthcare products Regulatory Agency (MHRA) and Commission on Human Medicines (CHM) [MHRA, 2007].
- In a Drug Safety Update, issued jointly by the MHRA and CHM, the review considered published and unpublished data and relevant clinical guidelines and concluded that [MHRA, 2007]:
- There is limited evidence to support the long-term clinical benefit of fibrate treatment in the primary or secondary prevention of cardiovascular disease (CVD). Given the robust evidence for statins in these indications, the use of fibrates as a first-line treatment is no longer justified.
- However, the effects of fibrates (mainly on triglycerides, and to a smaller extent on other lipid parameters) suggest that some subgroups of people may still benefit from a fibrate. In these subgroups, the overall benefit-risk balance of fibrates for specific indications remains positive.
- Combination therapy with a statin should only be used with caution due to a lack of robust evidence for their long-term clinical benefit, and the increased risk of myopathy and rhabdomyolysis. CKS recommends that combination therapy should only be initiated by specialists.
- The recommendation to use fibrates in people who can not tolerate a statin is supported by NICE. The Guidance Development Group did not find sufficient evidence to recommend the use of fibrates as a first-line treatment for primary or secondary prevention of CVD [National Collaborating Centre for Primary Care, 2008a; NICE, 2008a].
