Liver dysfunction concern for atorvastatin
Atorvastatin appears to cause cases of severe liver dysfunction more often than other statins, a new study concludes.
The researchers stressed hep-atotoxicity was a rare event, but advised GPs to be particularly vigilant in looking for signs of liver dysfunction in patients taking the drug.
Their study of patients admitted to a gastroenterology unit in Scotland identified seven cases of significant liver dysfunction associated with atorvastatin between 2002 and 2005, but none with other statins.
The researchers, who reported the results at the British
Society of Gastroenterology annual conference in Birmingham, said problems were twice as likely to occur in women and mainly affected patients over the age of 60.
Study leader Dr Peter Mills, consultant in general medicine at Gartnavel Hospital in Glasgow, said: 'Any persistent rise in the LFTs should prompt a review. Guidance should emphasise the need for increased vigilance in interpretation of LFTs.'
