Lovastatin Tablets and Zykadia

In the database of official manuals used in the service creation an interaction registered by statistical results of studies was found, which can either lead to negative consequences for the patient health or strengthen a mutual positive effect. A doctor should be consulted to address the issue of joint drug administration.

Consumer information for this interaction is not currently available.CONTRAINDICATED: Coadministration with potent inhibitors of CYP450 3A4 may significantly increase the plasma concentrations of simvastatin and lovastatin and their active acid metabolites, all of which are primarily metabolized by the isoenzyme. The interaction has been reported with potent CYP450 3A4 inhibitors such as azole antifungal agents, macrolide antibiotics, HIV protease inhibitors, and nefazodone. Clinically, high levels of HMG-CoA reductase inhibitory activity in plasma is associated with an increased risk of musculoskeletal toxicity. Myopathy manifested as muscle pain and/or weakness associated with grossly elevated creatine kinase exceeding ten times the upper limit of normal has been reported occasionally. Rhabdomyolysis has also occurred rarely, which may be accompanied by acute renal failure secondary to myoglobinuria and may result in death. MANAGEMENT: Due to the potential for severe interaction, concomitant use of simvastatin or lovastatin with potent CYP450 3A4 inhibitors is considered contraindicated. Red yeast rice, which contains lovastatin, should also be avoided. Fluvastatin, pravastatin, pitavastatin, and rosuvastatin are probably safer alternatives, since they are not metabolized by CYP450 3A4. All patients receiving statin therapy should be advised to promptly report any unexplained muscle pain, tenderness or weakness, particularly if accompanied by fever, malaise and/or dark colored urine. Therapy should be discontinued if creatine kinase is markedly elevated in the absence of strenuous exercise or if myopathy is otherwise suspected or diagnosed. References "Product Information.
