Mechanism of Action of Caat 40
Caat 40 contains Atorvastatin 40mg
Atorvastatin belongs to HMG-CoA reductase inhibitor pharmacological class and acts as an Antilipidemic therapeutic agent
Atorvastatin selectively and competitively inhibits HMG-CoA reductase, the enzyme that catalyzes the conversion of HMG-CoA to produce mevalonate. The reduction of mevalonate production results in a compensatory increase in the expression of LDL receptors and stimulation of LDL catabolism, consequently lowering LDL-cholesterol levels.
The onset of Action of Atorvastatin is within (Initial effect) 3-5 days.
The Duration of Action of Atorvastatin is within 20 to 30 hours.
The Tmax of Caat 40 is approximately 1-2 hours, and Cmax is within 1.95–252 μg/ml.
How to Use Caat 40
Caat 40, composed of 40mg of salt Atorvastatin, is available in the form of Oral Tablet.
Caat 40 is taken orally, usually once dailyUses of Caat 40
Caat 40 contains 40mg of salt Atorvastatin and is used in the treatment of Heterozygous familial hypercholesterolemia, Heterozygous familial hypercholesterolemia (pediatrics), Homozygous familial hypercholesterolemia, and Prevention of atherosclerotic cardiovascular disease. It is also used in the treatment of Transplantation, post-heart, Transplantation, and post-kidneyBenefits of Caat 40
Caat 40 contains 40mg of salt Atorvastatin. Atorvastatin competitively inhibits 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase. By preventing the conversion of HMG-CoA to mevalonate, statin medications decrease cholesterol production in the liver. Caat 40 also increases the number of LDL receptors on the surface of hepatic cells.

Dietary Restrictions and Safety Advice of Caat 40
Caat 40 should be used in the treatment of (approved indications) along with appropriate dietary restrictions
Hypercholesterolemia:
- Before initiation of therapy, patients should be placed on a standard cholesterol-lowering diet for 3 to 6 months and the diet should be continued during drug therapy. Atorvastatin serum concentration may be increased when taken with grapefruit juice; avoid concurrent intake of large quantities (>1.2 liters/day).
- Red yeast rice contains variable amounts of several compounds that are structurally similar to HMG-CoA reductase inhibitors, primarily monacolin K (or mevinolin) which is structurally identical to lovastatin; concurrent use of red yeast rice with HMG-CoA reductase inhibitors may increase the incidence of adverse and toxic effects.
The dietary restriction should be individualized as per patient requirements
Contraindications of Caat 40
Caat 40 contains 40mg of salt Atorvastatin and may be contraindicated in patients with
- Active liver disease, unexplained persistent serum transaminase elevation.
- Pregnancy and lactation.
- Concomitant use with ciclosporin, systemic fusidic acid, telaprevir, glecaprevir/pibrentasvir and tipranavir/ritonavir combinations.
Warnings and Precautions for Using Caat 40
Caat 40 containing Atorvastatin 40 should be used with certain warnings and precautions
The treating physician must closely monitor the patient and keep pharmacovigilance as follows
HDL Cholesterol
A paradoxical, severe, and reversible decrease in HDL-C (as low as 2 mg/dL) with a simultaneous decrease in apolipoprotein A1 has been reported within 2 weeks to years after initiation of fibrate therapy; the clinical significance is unknown.
● Venous thromboembolism
Use has been associated with pulmonary embolism and deep vein thrombosis. Use with caution in patients with risk factors for venous thromboembolism.
● Serum Creatinine
Elevations in serum creatinine have been reported in patients on Caat 40. These elevations tend to return to baseline following discontinuation of Caat 40 The clinical significance of these observations is unknown. Monitor renal function in patients with renal impairment taking Atorvastatin. Renal monitoring should also be considered for patients taking Atorvastatin and are at risk for renal insufficiency, such as the elderly and patients with diabetes.
● Cholelithiasis
Caat 40 contains 40mg of salt Atorvastatin, like clofibrate and gemfibrozil, which may increase cholesterol excretion into the bile, leading to cholelithiasis. If cholelithiasis is suspected, gallbladder studies are indicated. Atorvastatin therapy should be discontinued if gallstones are found.
● Coumarin Anticoagulants
Caution should be exercised when Atorvastatin is given in conjunction with coumarin anticoagulants. Caat 40 contains 40mg of salt Atorvastatin may potentiate the anticoagulant effects of these agents resulting in prolongation of the Prothrombin Time/International Normalized Ratio (PT/INR). To prevent bleeding complications, frequent monitoring of PT/INR and dose adjustment of the anticoagulant are recommended until PT/INR has stabilized.
● Pancreatitis
Pancreatitis has been reported in patients taking Atorvastatin, gemfibrozil, and clofibrate. This occurrence may represent a failure of efficacy in patients with severe hypertriglyceridemia, a direct drug effect, or a secondary phenomenon mediated through biliary tract stone or sludge formation with obstruction of the common bile duct.
● Hematologic Changes
Mild to moderate decreases in hemoglobin, hematocrit, and white blood cell decreases have been observed in patients following initiation of Atorvastatin therapy. However, these levels stabilize during long term administration. Thrombocytopenia and agranulocytosis have been reported in individuals treated with Atorvastatin. Periodic monitoring of red and white blood cell counts is recommended during the first 12 months of Caat 40 contains 40mg of salt Atorvastatin administration.
● Hypersensitivity Reactions
Acute hypersensitivity reactions including severe skin rashes such as Steven-Johnson syndrome and toxic epidermal necrolysis requiring patient hospitalization and treatment with steroids have been reported in individuals treated with Atorvastatin. Urticaria was seen in 1.1 vs. 0% and rash in 1.4 vs. 0.8% of Atorvastatin and placebo patients respectively in controlled trials.
Alcohol Warning
Alcohol Warning
Caat 40 may cause liver problems, and using it with substantial quantities of ethanol may increase that risk.
Breast Feeding Warning
Breast Feeding Warning
There is no available information on the presence of Caat 40 (Atorvastatin) in human milk, the effects of the drug on the breastfed infant, or the effects on milk production. Atorvastatin is present in the milk of rats and is therefore likely to be present in human milk. Because of the potential for serious adverse reactions in breastfed infants, such as disruption of infant lipid metabolism, women should not breastfeed during treatment with Atorvastatin and for 5 days after the final dosePregnancy Warning
Pregnancy Warning
Caat 40 contains 40mg of salt Atorvastatin which is contraindicated for use in pregnant women since safety in pregnant women has not been established, and there is no apparent benefit of lipid-lowering drugs during pregnancy. Because HMG-CoA reductase inhibitors decrease cholesterol synthesis and possibly the synthesis of other biologically active substances derived from cholesterol, Atorvastatin may cause fetal harm when administered to a pregnant woman. Atorvastatin should be discontinued as soon as pregnancy is recognized.
Food Warning
Food Warning
Grapefruit or grapefruit juice intake may elevate serum concentrations of Atorvastatin. Red yeast rice may increase the risk for toxic effects. Large consumption of alcoholic beverages may potentiate the risk for hepatic impairment. Decreased plasma concentrations with St. John's wortAdverse Reactions of Caat 40
The adverse reactions related to Caat 40 can be categorized as

Drug Interactions of Caat 40
The clinically relevant drug interactions of Caat 40 are briefly summarized here
- May increase risk of myopathy and rhabdomyolysis with moderate to potent CYP3A4 inhibitors (e.g. HIV and HCV protease inhibitors, itraconazole, ketoconazole, clarithromycin, erythromycin, verapamil, diltiazem), Atorvastatin, gemfibrozil, ezetimibe, niacin, colchicine, fixed combination of lopinavir/ritonavir. Concomitant use with CYP3A4 inducers (e.g. rifampicin, efavirenz, phenytoin), Al or Mg antacids, and colestipol may reduce plasma concentrations of Caat 40 May increase serum levels of digoxin and oral contraceptives (e.g., norethindrone, Ethinyl estradiol).
- Potentially Fatal: Concomitant use with ciclosporin, telaprevir, glecaprevir/pibrentasvir, and tipranavir/ritonavir combinations may potentiate the risk of myopathy or rhabdomyolysis. Coadministration with or within 7 days of stopping systemic fusidic acid may increase the risk of fatal rhabdomyolysis.
Side Effects of Caat 40
The common side effects of Caat 40 which contains 40mg of salt Atorvastatin include the following
Common
● Constipation, diarrhea, Heartburn, pain in the back, arm, or legs, Headache, joint pain.
Use of Caat 40 in Specific Populations
Geriatric Use
Caat 40 contains 40mg of salt Atorvastatin is known to be substantially excreted by the kidney, and the risk of adverse reactions to this drug may be greater in patients with impaired renal function. Atorvastatin exposure is not influenced by age. Since elderly patients have a higher incidence of renal impairment, dose selection for the elderly should be made based on renal function. Elderly patients with normal renal function should require no dose modifications. Consider monitoring renal function in elderly patients taking Atorvastatin.
Overdosage of Caat 40
The physician should be vigilant about the knowledge pertaining to the identification and treatment of Overdosage of Caat 40
There is no specific treatment for Caat 40 Overdosage. In the event of an overdose, the patient should be treated symptomatically,
And supportive measures instituted as required. Due to extensive drug binding to plasma proteins, hemodialysis is not expected to
Significantly enhance Atorvastatin clearance.
Clinical Pharmacology of Caat 40
Caat 40 contains 40mg of salt Atorvastatin
Pharmacodynamics
Atorvastatin, as well as some of its metabolites, are pharmacologically active in humans. The liver is the primary site of action and the Principal site of cholesterol synthesis and LDL clearance. Drug dosage, rather than systemic drug concentration, correlates better with LDL-C reduction. Individualization of drug dosage should be based on therapeutic response
Pharmacokinetics
- Absorption
Atorvastatin is rapidly absorbed after oral administration; maximum plasma concentrations occur within 1 to 2 hours. The extent of absorption increases in proportion to the Atorvastatin dose. The absolute bioavailability of Atorvastatin (parent drug) is approximately 14% and the systemic availability of HMG-CoA reductase inhibitory activity is approximately 30%. The low systemic availability is attributed to presystemic clearance in gastrointestinal mucosa and/or hepatic first-pass metabolism. Although food decreases the rate and extent of drug absorption by approximately 25% and 9%, respectively, as assessed by Cmax and AUC, LDL-C reduction is similar whether Atorvastatin is given with or without food. 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
- Distribution
The mean Volume of distribution of Atorvastatin is approximately 381 liters. Atorvastatin is ≥98% bound to plasma proteins. A blood/plasma ratio of approximately 0.25 indicates poor drug penetration into red blood cells. Based on observations in rats, Atorvastatin is likely to be secreted in human milk
- Metabolism
Atorvastatin is extensively metabolized to ortho- and parahydroxylated derivatives and various beta-oxidation products. In vitro, inhibition of HMG-CoA reductase by ortho- and parahydroxylated metabolites is equivalent to that of Atorvastatin. Approximately 70% of circulating inhibitory activity for HMG-CoA reductase is attributed to active metabolites. In vitro, studies suggest the importance of Atorvastatin metabolism by cytochrome p450 3a4, consistent with increased plasma concentrations of Atorvastatin in humans following co-administration with erythromycin, a known inhibitor of this isozyme. In animals, the ortho-hydroxy metabolite undergoes further glucuronidation.
- Excretion
Atorvastatin and its metabolites are eliminated primarily in bile following hepatic and/or extra-hepatic metabolism; however, the drug does not appear to undergo enterohepatic recirculation. The mean plasma elimination half-life of Atorvastatin in humans is approximately 14 hours, but the half-life of inhibitory activity for HMG-CoA reductase is 20 to 30 hours due to the contribution of active metabolites. Less than 2% of a dose of Atorvastatin is recovered in urine following oral administration.
