Anzitor 20

Indications of Anzitor 20

Anzitor ^® is indicated as an adjunct to diet for the reduction of elevated total cholesterol, LDL-cholesterol, apolipoprotein B, and triglycerides in patients with-
1. Primary hypercholesterolemia (heterozygous familial and non-familial hypercholesterolemia and mixed dyslipidemia (Fredrickson types IIa and IIb))
2. Elevated serum TG levels (Fredrickson type IV)
3. Primary dysbetalipoproteinemia (Fredrickson type III) who do not respond adequately to diet.
4. Homozygous familial hypercholesterolemia as an adjunct to other lipid-lowering treatments (eg, LDL apheresis) or if such treatments are unavailable.

 

Pharmacology of Anzitor 20

Anzitor ® is a selective, competitive inhibitor of HMG-CoA reductase, the rate-limiting enzyme responsible for the conversion of 3- hydroxy- 3- methyl- glutaryl- coenzyme A to mevalonate, a precursor of sterols, including cholesterol. Triglycerides (TG) and cholesterol in the liver are incorporated into VLDL and released into the plasma for delivery to peripheral tissues. Low-density lipoprotein (LDL) is formed from VLDL and is catabolized primarily through the high-affinity LDL receptor.

Anzitor ® lowers plasma cholesterol and lipoprotein levels by inhibiting HMG-CoA reductase and cholesterol synthesis in the liver and increases the number of hepatic LDL receptors on the cell surface for enhanced uptake and catabolism of LDL. Anzitor ® reduces LDL production and the number of LDL particles. Anzitor ® produces a profound and sustained increase in LDL receptor activity coupled with a beneficial change in the quality of circulating LDL particles.

 

Dosage & Administration

Patients should be placed on a standard cholesterol-lowering diet before receiving Anzitor ® and should continue on this diet during treatment with Anzitor ®. The usual starting dose for all the indications is 10 mg once daily. The doses range is 10 to 80 mg once daily. Doses should be individualized according to baseline LDL-C levels, the goal of therapy, and patient response. Adjustment of dosage should be made at intervals of 4 weeks or more. Doses may be given at any time of day with or without food.

Children:

• Treatment experience in a pediatric population with a dose of Anzitor® up to 80 mg/day is limited.

Geriatric (>70 years) use:

• The safety and efficacy of Anzitor ® in this population is as similar as < 70 years of age patients with a dose up to 80 mg/day.
  In patients with Renal Insufficiency: No dosage adjustment is required.

 

Interaction of Anzitor 20

The risk of myopathy during treatment with atorvastatin increases with the simultaneous administration of cyclosporine, fibric acid derivatives, erythromycin, azole antifungals, and niacin. When atorvastatin was used in combination with antihypertensive or hypoglycaemic drugs, no clinically significant interactions were observed. The patient should be closely monitored if atorvastatin is added to digoxin, erythromycin, oral contraceptives, colestipol, antacids, and warfarin.

 

Contraindications

Atorvastatin is contraindicated in patients with hypersensitivity to any component of this medication, active liver disease, or unexplained persistent elevations of serum transaminases, during pregnancy, while breastfeeding, and in women of child-bearing potential not using appropriate contraceptive measures.

 

Side Effects of Anzitor 20

Atorvastatin is generally well tolerated. Adverse reactions have usually been mild and transient. Reversible myositis is a rare but significant side effect of statins. The statins also cause headache, altered liver-function tests and gastrointestinal effects including abdominal pain, flatulence, diarrhea, nausea and vomiting. Thrombocytopenia, rash and hypersensitivity reactions have been reported rarely. Other side effects are reported with Atorvastatin therapy include insomnia, angioedema, anorexia, asthenia, paraesthesia, peripheral neuropathy, alopecia, pruritus, rash, impotence, chest pain, hypoglycemia and hyperglycemia.

 

Pregnancy & Lactation

Atorvastatin is contraindicated in pregnancy and while breastfeeding. Women of childbearing potential should use appropriate contraceptive measures. If the woman becomes pregnant while taking Atorvastatin, it should be discontinued.

 

Precautions & Warnings

Hepatic Effects: Liver function tests should be performed before starting treatment and regular check-ups thereafter. Patients who drink a lot of alcohol or have a history of liver disease should use atorvastatin with caution. If there is a significant increase in CPK levels or myopathy is diagnosed or suspected, treatment with atorvastatin should be discontinued.
