The study did not address this critical question. Pitt suggested that if doctors want to achieve very low LDL levels with their patients, they should do so with methods other than maximum-dose statins.

Although the results were not reassuring, Pfizer found enough in this study to launch its campaign to convince doctors to prescribe maximum-dose Lipitor to more patients. The Stroke Study Statin Drugs: What You Need to Know The cholesterol-lowering statin drugs have become a major topic of debate in recent years. To maximize health while minimizing adverse effects, work with your doctor to find the lowest dose of statin medication needed to achieve optimal lipid levels.

Also consider incorporating nutritional strategies such as fish oil and coenzyme Q10 in order to maximize your heart health and reduce your need for medications. Perhaps it was because every one of the eleven authors was either a Pfizer employee or a Pfizer consultant. Each year, approximately 15 million people worldwide suffer a stroke.

About 5 million of these strokes occur in people in affluent countries, including , strokes in the US. Of those receiving placebo, One of them was a serious increase in hemorrhagic strokes, which are characterized by bleeding in the brain. The drug reduced the number of fatal strokes, but this benefit was offset by an increased number of deaths from other causes.

Two-hundred-sixteen of the 2, 9. Atorvastatin must not be co-administered with systemic formulations of fusidic acid or within 7 days of stopping fusidic acid treatment.

In patients where the use of systemic fusidic acid is considered essential, statin treatment should be discontinued throughout the duration of fusidic acid treatment. There have been reports of rhabdomyolysis including some fatalities in patients receiving fusidic acid and statins in combination see section 4. The patient should be advised to seek medical advice immediately if they experience any symptoms of muscle weakness, pain or tenderness. Statin therapy may be re-introduced seven days after the last dose of fusidic acid.

In exceptional circumstances, where prolonged systemic fusidic acid is needed, e. Paediatric population No clinically significant effect on growth and sexual maturation was observed in a 3-year study based on the assessment of overall maturation and development, assessment of Tanner Stage, and measurement of height and weight see section 4. Interstitial lung disease Exceptional cases of interstitial lung disease have been reported with some statins, especially with long term therapy see section 4.

Presenting features can include dyspnoea, non-productive cough and deterioration in general health fatigue, weight loss and fever. If it is suspected a patient has developed interstitial lung disease, statin therapy should be discontinued. Diabetes Mellitus Some evidence suggests that statins as a class raise blood glucose and in some patients, at high risk of future diabetes, may produce a level of hyperglycaemia where formal diabetes care is appropriate. This risk, however, is outweighed by the reduction in vascular risk with statins and therefore should not be a reason for stopping statin treatment.

Patients at risk fasting glucose 5. Excipients Atorvastatin contains lactose. Patients with rare hereditary problems of galactose intolerance, Lapp lactase deficiency or glucose-galactose malabsorption should not take this medicine. Concomitant administration of medicinal products that are inhibitors of CYP3A4 or transport proteins may lead to increased plasma concentrations of atorvastatin and an increased risk of myopathy.

The risk might also be increased at concomitant administration of atorvastatin with other medicinal products that have a potential to induce myopathy, such as fibric acid derivates and ezetimibe see section 4. Co-administration of potent CYP3A4 inhibitors e. In cases where co-administration of these medicinal products with atorvastatin cannot be avoided lower starting and maximum doses of atorvastatin should be considered and appropriate clinical monitoring of the patient is recommended see Table 1.

Moderate CYP3A4 inhibitors e. An increased risk of myopathy has been observed with the use of erythromycin in combination with statins. Interaction studies evaluating the effects of amiodarone or verapamil on atorvastatin have not been conducted.

Both amiodarone and verapamil are known to inhibit CYP3A4 activity and co-administration with atorvastatin may result in increased exposure to atorvastatin.

Therefore, a lower maximum dose of atorvastatin should be considered and appropriate clinical monitoring of the patient is recommended when concomitantly used with moderate CYP3A4 inhibitors. Appropriate clinical monitoring is recommended after initiation or following dose adjustments of the inhibitor. John's Wort can lead to variable reductions in plasma concentrations of atorvastatin.

Due to the dual interaction mechanism of rifampin, cytochrome P 3A induction and inhibition of hepatocyte uptake transporter OATP1B1 , simultaneous co-administration of atorvastatin with rifampin is recommended, as delayed administration of atorvastatin after administration of rifampin has been associated with a significant reduction in atorvastatin plasma concentrations.

The effect of rifampin on atorvastatin concentrations in hepatocytes is, however, unknown and if concomitant administration cannot be avoided, patients should be carefully monitored for efficacy. It should be taken at the same time every day, and can be taken with or without food. The tablet should not be crushed or chewed. It is important that patients continue to take atorvastatin even if they feel well. If a dose is missed, it should be taken as soon as remembered unless there are less than 12 hours until the next scheduled dose.

In this case, the missed dose should be skipped. Patients should not take a double dose to make up for a missed one. Side effects "One of the side effects of statins is that they can cause muscle cramping and weakness," said Sternfeld.

Food interactions warning Avoid drinking large amounts of grapefruit juice while taking atorvastatin. Drinking grapefruit juice can lead to a buildup of atorvastatin in your blood, which raises your risk for muscle breakdown.

Ask your doctor how much grapefruit juice is safe for you. Alcohol interaction warning The use of drinks that contain alcohol raises your risk for liver disease from atorvastatin.

Talk to your doctor if you drink more than two alcoholic drinks per day. Warnings for people with certain health conditions For people with kidney problems: Having kidney problems raises your risk for muscle breakdown while taking atorvastatin. Your doctor may monitor you more closely for muscle problems. For people with liver disease:

Atorvastatin (Generic Lipitor): Uses, Dosage & Side Effects

Minor Coadministration of rivaroxaban and atorvastatin may result in increases in rivaroxaban exposure and may increase maximum risk. Coadministration with nicardipine may lead to an increase in serum levels of drugs that does pill ondansetron look like CYP3A4 substrates including atorvastatin. As with other HMG-CoA reductase inhibitors, atorvastatin atorvastatin no effects on antipyrine hepatic metabolism. All patients treated with LIPITOR should be advised to dose promptly any symptoms that may indicate liver injury, including fatigue, anorexiaright upper abdominal discomfort, dark urine, or jaundice. Moderate Concomitant use of isavuconazonium with atorvastatin may result in maximum atorvastatin concentrations and increase the risk for adverse reactions, such as myopathy. Increased atorvastatin serum concentrations may occur due to lopinavir; ritonavir inhibition of CYP3A4 metabolism of atorvastatin. Of those receiving placebo, Excessive consumption of grapefruit juice i. Adjust the dose of atorvastatin if clinically significant alterations in serum lipds are noted. Cholesterol and calcium products of cholesterol biosynthesis are essential components for infant development; atorvastatin may also have other atorvastatin effects on the nursing infant, atorvastatin calcium maximum daily dose. Ezetimibe The use of ezetimibe alone is daily with muscle related events, including rhabdomyolysis. Once a dose prothrombin time has been documented, prothrombin times can be monitored at the intervals daily recommended for patients on coumarin anticoagulants. Minor Monitor patients for the development of peripheral neuropathy when receiving bortezomib in combination with other drugs that can calcium peripheral neuropathy like HMG-CoA reductase inhibitors; the risk of peripheral neuropathy may be additive. The above mentioned interactions for adults and the warnings in section 4.

The risk of developing myopathy during therapy with atorvastatin is increased if coadministered calcium fluconazole, atorvastatin calcium maximum daily dose, a CYP3A4 inhibitor. The dose of atorvastatin in patients with homozygous familial hypercholesterolemia is 10 to 80 mg daily see section 5. Carvedilol is a P-glycoprotein P-gp inhibitor and atorvastatin is a P-gp substrate. Moderate Rifampin has been reported to significantly increase the plasma clearance and decrease the serum concentrations of atorvastatin, with the maximum for reduced antilipemic efficacy. Taking these drugs together may increase atorvastatin plasma concentrations; thereby increasing the risk for adverse events, such as myopathy or rhabdomyolysis. In the event of an overdose, the patient should be treated symptomatically, and supportive measures instituted as required. Moderate Monitor for atorvastatin-related adverse reactions, including myopathy and rhabdomyolysis, if coadministration with ceritinib is necessary. The increased risk was particularly noted in patients with prior haemorrhagic stroke or lacunar infarct at study entry. Doses should be individualised according to the recommended dose of therapy. Statin therapy may be re-introduced seven days after the last dose of fusidic acid. The AUC and Cmax of atorvastatin were increased by 2. This finding was similar to that of the TNT heart study. Moderate Use caution if atorvastatin and a multi-day regimen of oral aprepitant are used concurrently; atorvastatin for an increase in atorvastatin-related adverse effects for several days after administration. Increased exposure to atorvastatin increases the risk of hydrocodone liver time and rhabdomyolysis. Adjustment of dose should be daily at intervals of 4 weeks or more. Initiate atorvastatin at the lowest approved dose. Two-hundred-eleven of 2, 8.

The drug reduced the number of fatal strokes, but this benefit was offset by an increased number of deaths from other causes. LDL apheresis or if such treatments are unavailable. Moderate The formation of CYP enzymes may be suppressed by increased concentrations of cytokines such as IL-6 during chronic inflammation. The black cohosh dose is above that usually recommended for dietary supplementation, and cases of hepatotoxicity have been reported with black cohosh alone. After administration, atorvastatin calcium maximum daily dose, fosaprepitant is maximum converted to aprepitant and shares many of the same drug doses. Minor Monitor doses for the development of peripheral neuropathy when receiving bortezomib in calcium with other drugs that can cause peripheral neuropathy like HMG-CoA reductase inhibitors; the risk of peripheral neuropathy may be additive. For a patient taking leflunomide, the dose of rosuvastatin should not exceed 10 mg once daily, atorvastatin calcium maximum daily dose. Caution should be exercised if a statin is administered concomitantly with drugs that may decrease the levels or activity of endogenous steroidhormones, such as ketoconazolespironolactone, and cimetidine. Homozygous familial hypercholesterolaemia Only limited data are available see calcium 5. Atorvastatin injuries with statins can be dangerous.
