In Cambridgeshire and Peterborough colestyramine is recommended first line for the management of bile acid malabsorption (unlicensed indication). • Colestyramine is also used to help reduce the volume of jejunal and ileostomy outputs as a consequence of bowel resection for any cause3 and in patients with myeloma treatment induced diarrhoea that is unresponsive to loperamide.4 • Colesevelam 625mg tablets5 has a much more restricted range of licensed indications limited to treatment of hypercholesterolaemia and is recommended in Cambridgeshire and Peterborough as second line therapy for bile acid malabsorption after colestyramine and where conventional anti-diarrhoea medication have failed.6 • Colestipol7,8 is restricted to treatment of hypercholesterolaemia and is NON- FORMULARY in Cambridgeshire and Peterborough.

  • Pravafenix, INN-Pravastatin/Fenofibrate
    ANNEX I SUMMARY OF PRODUCT CHARACTERISTICS 1 1. NAME OF THE MEDICINAL PRODUCT Pravafenix 40 mg/160 mg hard capsules 2. QUALITATIVE AND QUANTITATIVE COMPOSITION Each hard capsule contains 40 mg pravastatin sodium and 160 mg fenofibrate. Excipient: Each hard capsule contains 19 mg of lactose. For a full list of excipients, see section 6.1. 3. PHARMACEUTICAL FORM Hard capsule. Pravafenix is a hard capsule, with light green body and olive cap, containing a waxy white beige mass and a tablet. 4. CLINICAL PARTICULARS 4.1 Therapeutic indications Pravafenix is indicated for the treatment of high coronary heart disease (CHD) -risk adult patients with mixed dyslipidaemia characterised by high triglycerides and low HDL-cholesterol levels whose LDL- C levels are adequately controlled while on a treatment with pravastatin 40 mg monotherapy. 4.2 Posology and method of administration Prior to initiating Pravafenix, secondary causes of combined dyslipidaemia should be excluded and patients should be placed on a standard cholesterol and triglycerides-lowering diet which should be continued during treatment. Posology The recommended dose is one capsule per day. Dietary restrictions instituted before therapy should be continued. Response to therapy should be monitored by determination of serum lipid values. Rapid reduction of serum lipid levels usually follows Pravafenix treatment, but treatment should be discontinued if an adequate response has not been achieved within three months.
