A case report of a ciprofloxacin and simvastatin interaction has been published in the latest issue of Canadian Journal of Clinical Pharmacology. The addition of ciprofloxacin to chronic simvastatin therapy led to the development of rhabdomyolysis.

Ezetimibe/Simvastatin (marketed as Vytorin)
FDA informed healthcare professionals that the Agency is investigating a report from the Simvastatin and Ezetimibe in Aortic Stenosis (SEAS) trial of a possible association between the use of Vytorin and a potentially increased incidence of cancer. Vytorin is a combination product of simvastatin and ezetimibe used to decrease the production of cholesterol by the liver and inhibit the absorption of cholesterol in the intestine to reduce LDL-cholesterol levels and reduce the risk of cardiovascular events. Recently, FDA obtained preliminary results from the SEAS trial. The clinical trial tested whether lowering LDL-cholesterol with Vytorin would reduce the risk of cardiovascular events in individuals with aortic stenosis. A lower overall cardiovascular risk was not found with Vytorin. However, there was an additional observation that a larger percentage of subjects treated with Vytorin were diagnosed with and died from all types of cancer combined when compared to placebo during the 5-year study.
FDA anticipates receiving a final SEAS study report in about 3 months and the Agency's review and evaluation of the clinical trial data and other relevant information should take approximately 6 months. FDA will communicate its conclusions and recommendations at that time. Healthcare professionals and caregivers should continue to monitor patients taking Vytorin and report side effects from the use of this drug to the Agency.

Simvastatin Used With Amiodarone
FDA notified healthcare professionals of the risk of muscle injury, rhabdomyolysis, which can lead to kidney failure or death, when simvastatin is used with amiodarone. This risk is dose-related and increases when a dose of simvastatin greater than 20 mg per day is given with amiodarone. Although a revision of the simvastatin labeling in 2002 described an increased risk of rhabdomyolysis when amiodarone is taken with simvastatin doses greater than 20 mg daily, FDA continues to receive reports of rhabdomyolysis in patients treated concurrently with amiodarone and simvastatin. Prescribers should be aware of the increased risk of rhabdomyolysis when simvastatin is prescribed with amiodarone, and they should avoid doses of simvastatin greater than 20 mg per day in patients taking amiodarone.

Ezetimibe/Simvastatin
FDA provided healthcare professionals with an early communication about an ongoing data review for Ezetimibe/Simvastatin (marketed as Vytorin), Ezetimibe (marketed as Zetia), and Simvastatin (marketed as Zocor).
This early communication is in keeping with FDA’s commitment to inform the public about ongoing postmarketing drug issues.Merck/Schering Plough Pharmaceuticals reported preliminary results from the Effect of Combination Ezetimibe and High-Dose Simvastatin vs. Simvastatin Alone on the Atherosclerotic Process in Patients with Heterozygous Familial Hypercholesterolemia (ENHANCE) trial. This trial was designed to evaluate the amount of atherosclerotic plaque in blood vessels located in the neck based on images obtained through ultrasound in patients treated with Vytorin (ezetimibe plus simvastatin) or simvastatin alone. Merck/Schering Plough stated that there was no significant difference between Vytorin and simvastatin in the amount of atherosclerotic plaque in the inner walls of the carotid (neck) arteries despite greater lowering of LDL-cholesterol (bad cholesterol) with Vytorin compared to simvastatin. Once Merck/Schering Plough completes the analysis of the unblinded data from ENHANCE, it will submit a final study report to FDA. Once FDA receives the final study report, FDA estimates it will take approximately 6 months to fully evaluate the data. After reviewing the data from the ENHANCE study, and considering all other available information about the link between LDL lowering and reduction of cardiovascular events, FDA will determine whether any further regulatory action is warranted with regard to Zetia and Vytorin and also whether any changes to FDA’s current approach to drugs that lower LDL cholesterol are warranted.
Patients should talk to their doctors if they have any questions about the information from the ENHANCE trial.
