PCE Dispertab and Simvastatin Tablets

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.

Using erythromycin together with simvastatin is not recommended. Combining these medications may significantly increase the blood levels of simvastatin. This can increase the risk of side effects such as liver damage and a rare but serious condition called rhabdomyolysis that involves the breakdown of skeletal muscle tissue. In some cases, rhabdomyolysis can cause kidney damage and even death. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications, or your doctor may prescribe alternative medications that do not interact. Let your doctor know immediately if you have unexplained muscle pain, tenderness, or weakness during treatment with simvastatin or similar medications, especially if these symptoms are accompanied by fever or dark colored urine. You should also seek immediate medical attention if you develop fever, chills, joint pain or swelling, unusual bleeding or bruising, skin rash, itching, loss of appetite, fatigue, nausea, vomiting, dark colored urine, and/or yellowing of the skin or eyes, as these may be signs and symptoms of liver damage. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

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 may be 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. 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.
