In short-term head-to-head studies of atorvastatin compared with rosuvastatin in patients with diabetes discount levitra soft 20mg on-line, the type and frequency of adverse events was similar to those found in studies of 78 buy cheap levitra soft 20 mg online, 95 cheap levitra soft 20mg overnight delivery, 231 patients without diabetes generic levitra soft 20 mg visa. In the Heart Protection Study (HPS, simvastatin), substantial elevations of liver enzymes and creatinine kinase were not significantly higher in patients with diabetes. Moreover, taking simvastatin for 5 years did not adversely affect glycemic control or renal function. It should be noted, however, that the Heart Protection Study had a run-in period in which patients who had liver or muscle enzyme elevations were excluded prior to randomization. A 4-month, head-to-head trial of extended-release fluvastatin 80 mg compared with atorvastatin 20 mg was conducted in 100 patients with type 2 diabetes and low serum high- 232 density lipoprotein levels. The study was designed to measure the metabolic effects of the statins and did not measure clinical endpoints. There were no significant changes in serum creatinine phosphokinase or liver enzymes and no major adverse events after 4 months of treatment. A 48-week trial assessed efficacy and safety of long-term treatment with fluvastatin in 233 patients with chronic renal disease and hyperlipidemia. Patients with diabetic nephropathy (N=34) or chronic glomerulonephritis (N=46) were randomized to fluvastatin 20 mg plus dietary therapy, or dietary therapy alone. Over 48 weeks of treatment, there were no significant differences between fluvastatin and placebo groups in serum creatinine concentration, creatinine clearance, or 24-hour urinary albumin excretion rates. Adverse event rates were similar between atorvastatin and placebo-treated patients 142 enrolled in the ASPEN trial. The rate of myalgia was more frequent with atorvastatin (3% compared with 1. Two cases of rhabdomyolysis were reported, 1 in each treatment arm. Neither of the cases were thought to be related to the interventions. Special populations and statin-drug interactions To assess whether a particular statin is safer in a special population, a review of potential drug interactions is necessary. We identified 7 non-systematic reviews pertaining to statin drug 206, 234-239 interactions. Briefly, simvastatin, lovastatin, and atorvastatin are all metabolized in the liver via the cytochrome P450 3A4 isoenzyme system. As a result, all 3 agents are susceptible to drug interactions when administered concomitantly with agents known to inhibit metabolism via CYP 3A4. The use of the agents listed below increases statin concentrations and, theoretically, Statins Page 64 of 128 Final Report Update 5 Drug Effectiveness Review Project the possibility for adverse effects and does not include all drugs capable of inhibiting metabolism via the CYP 3A4 isoenzyme system. The significance of interactions with many drugs that inhibit CYP 3A4 is not known; examples include diltiazem, verapamil, and fluoxetine. Fluvastatin is primarily metabolized via CYP 2C9 and is vulnerable to interactions with drugs known to inhibit CYP 2C9 metabolism. Only about 10% of rosuvastatin is metabolized, primarily through the CYP 2C9 system. Pravastatin is not significantly metabolized via the CYP isoenzyme system and is therefore not affected by drugs inhibiting metabolism via these pathways. Several pharmacokinetic studies have suggested potential drug interaction with atorvastatin (and other CYP 3A4 statins) and clopidogrel. Clopidogrel is a prodrug that requires activation via CYP 3A4/2C19. Of these, 8 studies collectively showed little difference in the risk of cardiovascular events (myocardial infarction, death, revascularization, hospitalization, etc) in patients at high risk for atherothrombotic events (with or without percutaneous coronary intervention) for those receiving statin-clopidogrel combination compared with those using statin or clopidogrel monotherapy. There was also a minimal difference in risk between groups when statins were stratified by whether they were metabolized by 3A4 or non-3A4 pathways. Study designs were retrospective or post-hoc analyses of larger randomized trials. Each study had its limitations such as small sample size (lack of power), unknown statin doses, unclear duration of statin or clopidogrel combination therapy, potential selection bias in database studies, and unknown adherence to therapy; thus, the results should be interpreted carefully. We found 1 small retrospective review (N=13) that assessed the potential drug interaction with the combination of simvastatin to an efavirenz-based regimen in HIV-infected and non-infected patients. Efavirenz is a non-nucleoside reverse transcriptase inhibitor that has CYP 3A4 inductive effects and the combination with simvastatin, a 3A4 substrate, could potentially lead to less of a statin treatment effect.
