A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.
The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.
Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.
Ezallor Sprinkle™ (rosuvastatin) capsules are indicated as an: Adjunctive therapy to diet for the treatment of adult patients with hypertriglyceridemia Adjunct to diet for the treatment of adult patients with primary dysbetalipoproteinemia (Type III hyperlipoproteinemia) Adjunctive therapy to other lipid-lowering treatments (e.g., LDL apheresis) or alone if such treatments are unavailable to reduce LDL-C, total-C, and ApoB in adult patients with homozygous familial hypercholesterolemia
Skeletal Muscle Effects: Cases of myopathy and rhabdomyolysis with acute renal failure secondary to myoglobinuria have been reported with HMG-CoA reductase inhibitors, including rosuvastatin. These risks can occur at any dose level, but are increased at the highest dose (40 mg). Ezallor Sprinkle™ should be prescribed with caution in patients with predisposing factors for myopathy (e.g. aged =65 years, inadequately treated hypothyroidism, renal impairment). The risk of myopathy during treatment with Ezallor Sprinkle™ may be increased with concurrent administration of gemfibrozil, some other lipid-lowering therapies (other fibrates or niacin), cyclosporine, darolutamide, regorafenib, atazanavir/ritonavir, lopinavir/ritonavir, simeprevir or combination of sofosbuvir/velpatasvir/voxilaprevir, dasabuvir/ombitasvir/paritaprevir/ritonavir, elbasvir/grazoprevir, sofosbuvir/velpatasvir, glecaprevir/pibrentasvir, all combinations with ledipasvir (including ledipasvir/sofosbuvir). Ezallor Sprinkle™ therapy should be discontinued if markedly elevated CK levels occur or myopathy is diagnosed or suspected. Immune-Mediated Necrotizing Myopathy (IMNM): There have been rare reports of IMNM, an autoimmune myopathy, associated with statin use. IMNM is characterized by proximal muscle weakness and elevated serum creatine kinase, which persist despite discontinuation of statin treatment; positive anti-HMG-CoA reductase antibody; muscle biopsy showing necrotizing myopathy; and improvement with immunosuppressive agents. Liver Enzyme Abnormalities: It is recommended that liver enzyme tests be performed before the initiation of Ezallor Sprinkle™, and if signs or symptoms of liver injury occur. There have been rare postmarketing reports of fatal and non-fatal hepatic failure in patients taking statins, including rosuvastatin. If serious liver injury with clinical symptoms and/or hyperbilirubinemia or jaundice occurs during treatment with Ezallor Sprinkle™, promptly interrupt therapy. If an alternate etiology is not found, do not restart Ezallor Sprinkle™. Ezallor Sprinkle™ should be used with caution in patients who consume substantial quantities of alcohol and/or have a history of chronic liver disease. Active liver disease, which may include unexplained persistent transaminase elevations, is a contraindication to the use of Ezallor Sprinkle™. Concomitant Coumarin Anticoagulants: Caution should be exercised when anticoagulants are given in conjunction with Ezallor Sprinkle™ because of its potentiation of the effect of coumarin-type anticoagulants in prolonging the prothrombin time/INR. In patients taking coumarin anticoagulants and Ezallor Sprinkle™ concomitantly, INR should be determined before starting Ezallor Sprinkle™ and frequently enough during early therapy to ensure that no significant alteration of INR occurs. Proteinuria and Hematuria: Dipstick-positive proteinuria and microscopic hematuria were observed among patients treated with rosuvastatin. These findings were more frequent in patients taking rosuvastatin 40 mg, though it was generally transient and was not associated with worsening renal function. Although the clinical significance of this finding is unknown, dose reduction should be considered for patients on Ezallor Sprinkle™ therapy with unexplained persistent proteinuria and/or hematuria during routine urinalysis testing. Endocrine Effects: Increases in HbA1c and fasting serum glucose levels have been reported with statins, including rosuvastatin. Based on clinical trial data with rosuvastatin, in some instances these increases may exceed the threshold for the diagnosis of diabetes mellitus.
In the controlled clinical trials database, the most common adverse reactions were headache, myalgia, abdominal pain, asthenia, and nausea. There have been rare reports of immune-mediated myopathy associated with statin use. There have been rare postmarketing reports of cognitive impairment (e.g. memory loss, forgetfulness, amnesia, memory impairment, and confusion) associated with statin use. These cognitive issues have been reported for all statins. The reports are generally non-serious, and reversible upon statin discontinuation, with variable times to symptom onset (1 day to years) and symptom resolution (median of 3 weeks).
