Simvastatin

Simvastatin is antihyperlipidic agent. Simvastatin is structural analog of HMG-CoA (3-hydroxy-3-methylglutaryl-coenzyme). Like other agents, it inhibits the enzyme hydroxymethylglutaryl-CoA (HMG-CoA) reductase. It has an extremely high affinity for this enzyme and was considered the most potent agent of the HMG-CoA class until atorvastatin was approved. Simvastatin is inactive lactone prodrug and hydrolyzed in the gastrointestinal tract to the active β hydroxy derivative. It was approved by the FDA in December 1991. It decreases total cholesterol, LDL cholesterol, triglycerides, and apolipoprotein B, while increasing HDL.

Interactions
Simvastatin is known to interact with other drugs, the details of drug interactions is as follows:DrugDetailsSeverityOnsetManagementAmiodarone (HCl)Increased risk of myopathy when amiodarone is given with simvastatin. MajorAvoid doses of simvastatin above 20 mg daily.AmprenavirAmprenavir possibly increases plasma concentration of Simvastatin. ADVICE: Avoid concomitant use.MajorAtazanavirAtazanavir inhibits the hepatic metabolism of simvastatin results in increased plasma concentration.MajorThis combination is considered contraindicated. Patient should notify to physician if experience unexplained muscle pain, tenderness, or weakness, malaise or fever. Discontinue therapy if level of creatinine kinase is increased or if myopathy diagnosed.BosentanBosentan possibly reduces plasma concentration of Simvastatin.CiprofibrateColestipol (HCl)DanazolConcomitant administeration can lead to RhabdomyolysisDigoxinConcomitant administerationn can slightly increase in digoxin levelItraconazoleKetoconazoleLinagliptin10 mg of Linagliptin increases AUC by 34% and Cmax by 10% of simvastatin (40 mg)Mibefradil (Di HCl)TelithromycinSimvastatin levels were increased by Teicoplanin when used concurrently.Ticagrelorsimvastatin is metabolised by CYP3A4 engzyme ( other e.g; Atorvastatin ) so ticagrelor may increase cmax of simvastatin by 81%, AUC 56%dose of Atorvastatin, symvastatin should be less than 40mg, greater than 40mg is not recommendedTocilizumabToclizumab decreases exposure of simvastatinVORICONAZOLEVoriconazole may increase the serum concentration of simvastatin by decreasing its metabolism. Monitor for changes in the therapeutic and adverse effects Warfarin (Na)Simvastatin may enhance the anticoagulant effect of Warfarin. Moderate (Sequence important)Monitor for increased effects of Warfarin if Simvastatin is initiated/dose increased, or decreased effects if Simvastatin is discontinued/dose decreased. Dosage adjustments of Warfarin may be needed. These interactions are sometimes beneficial and sometimes may pose threats to life. Always consult your physician for the change of dose regimen or an alternative drug of choice that may strictly be required.
