Because of a last minute change in an FDA ruling, generic lovastatin will not be available until after December 15, contrary to the statement in the September 17 Medical Letter article on Substituing for Cerivastatin (vol. 23, page 79)

Full-page newspaper advertisements are urging patients with high cholesterol levels who are stopping Baycol (cerivastatin) to ask their doctors about Pravachol (pravastatin), Lipitor (atorvastatin), Zocor (simvastatin) or Lescol (fluvastatin). Some advertisements come with a coupon for free medication. Lovastatin, which is available generically, has not appeared in similar advertisements. Cerivastatin was withdrawn from the market on August 8 because of post-marketing reports of 31 cases of fatal rhabdomyolysis.

New recommendations for drug treatment of hypercholesterolemia, if widely followed, will lead to a marked increase in the number of people taking lipid-regulating drugs.

Drugs that lower-density-lipoprotein (LDL) cholesterol concentrations can prevent formation, slow progression and cause regression of atherosclerotic lesions, improve coronary vasodilatation, and decrease mortality from coronary heart disease. All of these drugs must be continued indefinitely; when they are stopped, plasma cholesterol concentrations generally return to pretreatment levels. Elevated serum triglyceride concentrations appear to be an independent risk factor for cardiovascular disease in both women and men, but direct evidence of clinical benefit from triglyceride reduction is lacking.

Cerivastatin (Baycol - Bayer), a new HMG-CoA reductase inhibitor (or "statin"), has been approved by the FDA for treatment of hypercholesterolemia. Cerivastatin is the sodium salt of a synthetic fluorophenyl pyridinyl-substituted heptanoic acid.
