Atorvastatin (Lipitor®), is a lipid-lowering drug included in the statin class of medications. By inhibiting the endogenous production of cholesterol in the liver, statins lower abnormal cholesterol and lipid levels, and ultimately reduce the risk of cardiovascular disease. More specifically, statin medications competitively inhibit the enzyme hydroxymethylglutaryl-coenzyme A (HMG-CoA) Reductase, which catalyzes the conversion of HMG-CoA to mevalonic acid. This conversion is a critical metabolic reaction involved in the production of several compounds involved in lipid metabolism and transport, including cholesterol, low-density lipoprotein (LDL) (sometimes referred to as "bad cholesterol"), and very-low-density lipoprotein (VLDL). Prescribing statins is considered standard practice for patients following any cardiovascular event, and for people who are at moderate to high risk of developing cardiovascular disease. The evidence supporting statin use, coupled with minimal side effects and long term benefits, has resulted in wide use of this medication in North America.
Atorvastatin and other statins including lovastatin, pravastatin, rosuvastatin, fluvastatin, and simvastatin are considered first-line treatment options for dyslipidemia. The increasing use of this class of drugs is largely attributed to the rise in cardiovascular diseases (CVD) (such as heart attack, atherosclerosis, angina, peripheral artery disease, and stroke) in many countries. An elevated cholesterol level (elevated low-density lipoprotein (LDL) levels in particular) is a significant risk factor for the development of CVD. Several landmark studies demonstrate that the use of statins is associated with both a reduction in LDL levels and CVD risk. Statins were shown to reduce the incidences of all-cause mortality, including fatal and non-fatal CVD, as well as the need for surgical revascularization or angioplasty following a heart attack. Some evidence has shown that even for low-risk individuals (wAtorvastatin is an oral antilipemic agent that reversibly inhibits HMG-CoA reductase. It lowers total cholesterol, low-density lipoprotein-cholesterol (LDL-C), apolipoprotein B (apo B), non-high density lipoprotein-cholesterol (non-HDL-C), and triglyceride (TG) plasma concentrations while increasing HDL-C concentrations. High LDL-C, low HDL-C and high TG concentrations in the plasma are associated with increased risk of atherosclerosis and cardiovascular disease. The total cholesterol to HDL-C ratio is a strong predictor of coronary artery disease, and high ratios are associated with a higher risk of disease. Increased levels of HDL-C are associated with lower cardiovascular risk. By decreasing LDL-C and TG and increasing HDL-C, atorvastatin reduces the risk of cardiovascular morbidity and mortality.
Elevated cholesterol levels (and high low-density lipoprotein (LDL) levels in particular) are an important risk factor for the development of CVD. Clinical studies have shown that atorvastatin reduces LDL-C and total cholesterol by 36-53%. In patients with dysbetalipoproteinemia, atorvastatin reduced the levels of intermediate-density lipoprotein cholesterol. It has also been suggested that atorvastatin can limit the extent of angiogenesis, which can be useful in the treatment of chronic subdural hematoma.
Fenofibrate is a fibric acid derivative, a prodrug comprising fenofibric acid linked to an isopropyl ester. Fenofibrate is rapidly hydrolyzed after oral ingestion to its pharmacologically active form, fenofibric acid. The effects of fenofibric acid seen in clinical practice have been explained in vivo in transgenic mice and in vitro in human hepatocyte cultures by the activation of peroxisome proliferator activated receptor α (PPARα)
It lowers lipid levels by activating peroxisome proliferator-activated receptor alpha (PPARα). PPARα activates lipoprotein lipase and reduces apoprotein CIII (an inhibitor of lipoprotein lipase activity), which increases lipolysis and elimination of triglyceride-rich particles from plasma. The resulting fall in triglycerides produces an alteration in the size and composition of LDL from small, dense particles (which are thought to be atherogenic due to their susceptibility to oxidation), to large buoyant particles. These larger particles have a greater affinity for cholesterol receptors and are catabolized rapidly
PPARα also increases apoproteins AI and AII, reduces VLDL- and LDL-containing apoprotein B, and increases HDL-containing apoprotein AI and AII. Fenofibrate also reduces serum uric acid levels in hyperuricemic and normal individuals by increasing the urinary excretion of uric acid.
Fenofibrate is a fibrate that activates peroxisome proliferator activated receptor alpha (PPARα) to alter lipid metabolism and treat primary hypercholesterolemia, mixed dyslipidemia, and severe hypertriglyceridemia. Fenofibrate requires once daily dosing and has a half life of 19-27 hours so its duration of action is long. Fenofibrate capsules are given at a dose of 50-150mg daily so the therapeutic index is wide. Patients should be counselled about the risk of rhabdomyolysis, myopathy, and cholelithiasis when taking fibrates.

Uses
Atorvastatin is an HMG-CoA reductase inhibitor used to lower lipid levels and reduce the risk of cardiovascular disease including myocardial infarction and stroke.
Atorvastatin is indicated for the treatment of several types of dyslipidemias, including primary hyperlipidemia and mixed dyslipidemia in adults, hypertriglyceridemia, primary dysbetalipoproteinemia, homozygous familial hypercholesterolemia, and heterozygous familial hypercholesterolemia in adolescent patients with failed dietary modifications.
Dyslipidemia describes an elevation of plasma cholesterol, triglycerides or both as well as to the presence of low levels of high-density lipoprotein. This condition represents an increased risk for the development of atherosclerosis.
Atorvastatin is indicated, in combination with dietary modifications, to prevent cardiovascular events in patients with cardiac risk factors and/or abnormal lipid profiles.
Atorvastatin can be used as a preventive agent for myocardial infarction, stroke, revascularization, and angina, in patients without coronary heart disease but with multiple risk factors and in patients with type 2 diabetes without coronary heart disease but multiple risk factors.
Atorvastatin may be used as a preventive agent for non-fatal myocardial infarction, fatal and non-fatal stroke, revascularization procedures, hospitalization for congestive heart failure and angina in patients with coronary heart disease.
Prescribing of statin medications is considered standard practice following any cardiovascular events and for people with a moderate to high risk of development of CVD. Statin-indicated conditions include diabetes mellitus, clinical atherosclerosis (including myocardial infarction, acute coronary syndromes, stable angina, documented coronary artery disease, stroke, trans ischemic attack (TIA), documented carotid disease, peripheral artery disease, and claudication), abdominal aortic aneurysm, chronic kidney disease, and severely elevated LDL-C levels.
Fenofibrate is used for an adjunct to diet and other non pharmacological treatment (e.g. exercise, weight reduction) for the following:
- Treatment of severe hypertriglyceridemia with or without low HDL cholesterol.
- Mixed hyperlipidemia when a statin is contraused or not tolerated.
- Mixed hyperlipidemia in patients at high cardiovascular risk in addition to a statin when triglycerides and HDL cholesterol are not adequately controlled
Vasolip F is also used to associated treatment for these conditions: Anginal Pain, Cardiovascular Disease (CVD), Coronary Artery Disease (CAD), Coronary artery thrombosis, Dysbetalipoproteinemia, Fredrickson Type III lipidemia, Heterozygous Familial Hypercholesterolemia, High Blood Pressure (Hypertension), High Cholesterol, Homozygous Familial Hypercholesterolemia, Hospitalizations, Hypertriglyceridemias, Mixed Dyslipidemias, Mixed Hyperlipidemia, Myocardial Infarction, Non-familial hypercholesterolemia, Postoperative Thromboembolism, Primary Hypercholesterolemia, Stroke, Transient Ischemic Attack, Elevation of serum triglyceride levels, Heterozygous familial hyperlipidemia, Non-familial hyperlipidemia, Non-fatal myocardial infarction, Primary Hyperlipidemia, Revascularization procedures, Revascularization process, Thrombotic events, Cardiovascular Primary Prevention, Secondary prevention cardiovascular eventMixed Dyslipidemias, Primary Hypercholesterolemia, Severe Hypertriglyceridemia, Severe Fredrickson Type IV Hypertriglyceridemia, Severe Fredrickson Type V Hypertriglyceridemia
How Vasolip F works
Atorvastatin is a statin medication and a competitive inhibitor of the enzyme HMG-CoA (3-hydroxy-3-methylglutaryl coenzyme A) reductase, which catalyzes the conversion of HMG-CoA to mevalonate, an early rate-limiting step in cholesterol biosynthesis. Atorvastatin acts primarily in the liver, where decreased hepatic cholesterol concentrations stimulate the upregulation of hepatic low-density lipoprotein (LDL) receptors, which increases hepatic uptake of LDL. Atorvastatin also reduces Very-Low-Density Lipoprotein-Cholesterol (VLDL-C), serum triglycerides (TG) and Intermediate Density Lipoproteins (IDL), as well as the number of apolipoprotein B (apo B) containing particles, but increases High-Density Lipoprotein Cholesterol (HDL-C).
In vitro and in vivo animal studies also demonstrate that atorvastatin exerts vasculoprotective effects independent of its lipid-lowering properties, also known as the pleiotropic effects of statins. These effects include improvement in endothelial function, enhanced stability of atherosclerotic plaques, reduced oxidative stress and inflammation, and inhibition of the thrombogenic response. Statins were also found to bind allosterically to β2 integrin function-associated antigen-1 (LFA-1), which plays an essential role in leukocyte trafficking and T cell activation.
Fenofibrate activates peroxisome proliferator activated receptor alpha (PPARα), increasing lipolysis, activating lipoprotein lipase, and reducing apoprotein C-III. PPARα is a nuclear receptor and its activation alters lipid, glucose, and amino acid homeostasis. Activation of PPARα activates transcription of gene transcription and translation that generates peroxisomes filled with hydrogen peroxide, reactive oxygen species, and hydroxyl radicals that also participate in lipolysis. This mechanism of increased lipid metabolism is also associated with increased oxidative stress on the liver. In rare cases this stress can lead to cirrhosis and chronic active hepatitis.
Dosage
Vasolip F dosage
The dose is one 200 mg capsule per day. Dosage should be individualized according to patient response, and should be increased sequentially if necessary following repeat serum triglyceride estimations at 4 to 8 week intervals. Patients should be placed on an appropriate triglyceride-lowering diet before receiving fenofibrate, and should continue this diet during treatment with fenofibrate. Fenofibrate should be given with meals, thereby optimizing the bioavailability of the medication.
Side Effects
Digestive: hepatitis, cholelithiasis, cholecystitis, hepatomegaly
Musculoskeletal: myalgia, myasthenia, rhabdomyolysis
Skin and appendages: photosensitivity, eczema
Cardiovascular: peripheral edema, angina, palpitations, tachycardia, and migraine
Toxicity
The reported LD50 of oral atorvastatin in mice is higher than 5000 mg/kg. In cases of overdose with atorvastatin, there is reported symptoms of complicated breathing, jaundice, liver damage, dark urine, muscle pain, and seizures. In case of overdose, symptomatic treatment is recommended and due to the high plasma protein binding, hemodialysis is not expected to generate significant improvement.
In carcinogenic studies with high doses of atorvastatin, evidence of rhabdomyosarcoma, fibrosarcoma, liver adenoma, and liver carcinoma were observed.
In fertility studies with high doses of atorvastatin, there were events of aplasia, aspermia, low testis and epididymal weight, decreased sperm motility, decreased spermatid head concentration and increased abnormal sperm.
Atorvastatin was shown to not be mutagenic in diverse mutagenic assays.
The oral LD50 in rats is >2g/kg and in mice is 1600mg/kg. The oral TDLO in rats is 9mg/kg.
Treat patients with supportive care including monitoring of vital signs and observing clinical status. Recent overdose may be treated with inducing vomiting or gastric lavage. Due to fenofibrate's extensive protein binding, hemodialysis is not expected to be useful.
Precaution
Increased risk of cholelithiasis, pancreatitis, skeletal muscle effects. Patient at risk of rhabdomyolysis. Renal impairment. Pregnancy.
Interaction
Oral Anticoagulants: Caution should be exercised when anticoagulants are given in conjunction with fenofibrate. The dosage of the anticoagulants should be reduced to maintain the prothrombin time at the desired level to prevent bleeding complications.
Resins: Since bile acid sequestrants may bind other drugs given concurrently, patients should take fenofibrate at least 1 hour before or 4-6 hours after a bile acid binding resin to avoid impending its absorption.
Cyclosporine: Because cyclosporine can produce nephrotoxicity with decreases in creatinine clearance and rises in serum creatinine, and because renal excretion is the primary elimination route of fibrate drugs including fenofibrate, there is a risk that an interaction will lead to deterioration.
Volume of Distribution
The reported volume of distribution of atorvastatin is of 380 L.
The volume of distribution of fenofibrate is 0.89L/kg, and can be as high as 60L.
Elimination Route
Atorvastatin presents a dose-dependent and non-linear pharmacokinetic profile. It is very rapidly absorbed after oral administration. After the administration of a dose of 40 mg, its peak plasma concentration of 28 ng/ml is reached 1-2 hours after initial administration with an AUC of about 200 ng∙h/ml. Atorvastatin undergoes extensive first-pass metabolism in the wall of the gut and the liver, resulting in an absolute oral bioavailability of 14%. Plasma atorvastatin concentrations are lower (approximately 30% for Cmax and AUC) following evening drug administration compared with morning. However, LDL-C reduction is the same regardless of the time of day of drug administration.
Administration of atorvastatin with food results in prolonged Tmax and a reduction in Cmax and AUC.
Breast Cancer Resistance Protein (BCRP) is a membrane-bound protein that plays an important role in the absorption of atorvastatin. Evidence from pharmacogenetic studies of c.421C>A single nucleotide polymorphisms (SNPs) in the gene for BCRP has demonstrated that individuals with the 421AA genotype have reduced functional activity and 1.72-fold higher AUC for atorvastatin compared to study individuals with the control 421CC genotype. This has important implications for the variation in response to the drug in terms of efficacy and toxicity, particularly as the BCRP c.421C>A polymorphism occurs more frequently in Asian populations than in Caucasians. Other statin drugs impacted by this polymorphism include fluvastatin, simvastatin, and rosuvastatin.
Genetic differences in the OATP1B1 (organic-anion-transporting polypeptide 1B1) hepatic transporter encoded by the SCLCO1B1 gene (Solute Carrier Organic Anion Transporter family member 1B1) have been shown to impact atorvastatin pharmacokinetics. Evidence from pharmacogenetic studies of the c.521T>C single nucleotide polymorphism (SNP) in the gene encoding OATP1B1 (SLCO1B1) demonstrated that atorvastatin AUC was increased 2.45-fold for individuals homozygous for 521CC compared to homozygous 521TT individuals.[A181493] Other statin drugs impacted by this polymorphism include simvastatin, pitavastatin, rosuvastatin, and pravastatin.
A single 300mg oral dose of fenofibrate reaches a Cmax of 6-9.5mg/L with a Tmax of 4-6h in healthy, fasting volunteers.
Half Life
The half-life of atorvastatin is 14 hours while the half-life of its metabolites can reach up to 30 hours.
Fenofibric acid, the active metabolite of fenofibrate, has a half life of 23 hours. Fenofibrate has a half life of 19-27 hours in healthy subjects and up to 143 hours in patients with renal failure.
Clearance
The registered total plasma clearance of atorvastatin is of 625 ml/min.
The oral clearance of fenofibrate is 1.1L/h in young adults and 1.2L/h in the elderly.
Elimination Route
Atorvastatin and its metabolites are mainly eliminated in the bile without enterohepatic recirculation. The renal elimination of atorvastatin is very minimal and represents less than 1% of the eliminated dose.
5-25% of a dose of fenofibrate is eliminated in the feces, while 60-88% is eliminated in the urine. 70-75% of the dose recovered in the urine is in the form of fenofibryl glucuronide and 16% as fenofibric acid.
Pregnancy & Breastfeeding use
Pregnancy Category C. Fenofibrate should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Nursing mothers: Fenofibrate should not be used in nursing mothers. Because of the potential for tumorigenicity seen in animal studies, a decision should be made whether to discontinue nursing or to discontinue the drug.
