Abstract
Statins are one of the most crucial drugs used for the prevention of atherosclerotic coronary artery disease. A wide spectrum of symptoms ranging from myalgia to symptoms of rhabdomyolysis with or without weakness of the upper and lower limbs are indicative of statin-induced rhabdomyolysis or myopathy. The current case series which represents three patients who developed statin-induced myopathy after starting rosuvastatin is one of a few if not the first case series. All three patients had recently started rosuvastatin 40mg once daily post-percutaneous transluminal coronary angioplasty (PTCA) for secondary prevention of atherosclerotic cardiovascular diseases (ASCVDs). Shortly after starting the medication, they were hospitalized due to bilateral lower limb pain and weakness. On further evaluation, they were diagnosed to have rosuvastatin-induced myopathy with acute kidney injury and/or liver injury. In all cases, myopathy, acute renal injury, and liver injury were caused by rosuvastatin, regardless of the presence of a vitamin D deficiency. Despite the documented risk of myopathy and renal toxicity associated with rosuvastatin, the drug remains highly popular worldwide in the modern period. Although all the cases discussed were successfully treated by stopping rosuvastatin and switching it with another class of lipid-lowering agent, it significantly increased morbidity and raised medical expenses. Hence, this case series not only adds to existing safety disputations associated with rosuvastatin but also calls for more pharmacovigilance when recommending this medication.
