AstraZeneca's Crestor doubles side effects-study

AstraZeneca's cholesterol-lowering drug Crestor has more than double the side effects of rival statin drugs, including deaths, U.S. researchers reported on Monday.

Adverse effects include muscle damage known as myopathy, including a severe form known as rhabdomyolysis; proteinuria or protein in the urine; nephropathy, a reduced ability of the kidneys to filter toxins from the blood; and kidney failure.

Dr. Richard Karas of the Tuft-New England Medical Center in Boston, who led the study, said his team found a rate of 28 adverse events per million prescriptions of Crestor, known generically as rosuvastatin.

Karas said there were 6 per million deaths on Crestor as compared to 3 per million for Zocor, 1 per million with Bristol Myers Squibb's Pravachol and 2 per million for Lipitor.

In March, the FDA denied a petition by the consumer group Public Citizen to ban Crestor, saying it disagreed with arguments that Crestor was more dangerous than other statins.
