Atorvastatin work the, marketed under the trade name Lipitor among others, [1] is a member of the medication class known as statinswhich are used primarily as a lipid-lowering body organs and for prevention of events associated with cardiovascular disease. Like all statins, atorvastatin works by inhibiting HMG-CoA reductasean enzyme found in liver tissue that plays a key role in production of cholesterol in the body.
The primary uses of atorvastatin is for the treatment of dyslipidemia and the prevention of cardiovascular disease: There have been recent studies how does lipitor work in the body organs that high-dose /januvia-rash-pictures-1-year-old.html therapy plays a plaque-stabilizing role in people suffering from acute coronary syndrome and thrombotic stroke.
Atorvastatin may be used in combination with bile acid sequestrants and ezetimibe to increase the reduction in cholesterol levels. However, It is not recommended to combine statin medication treatment with certain other cholesterol-lowering medications, particularly fibratesbecause this may increase the risk of myopathy-related adverse effects.
While many statin medications should be administered at bedtime for optimal effect, atorvastatin can be dosed how does lipitor work in the body organs any time of day, as long as it is continually dosed once daily at the same time. High-dose atorvastatin have also been associated with worsening blood sugar control.
Inthe Food and Drug Administration FDA body organs memory loss, forgetfulness and confusion with all body organs products including atorvastatin. The symptoms were not serious, and they were rare and reversible on cessation of treatment with the medication. Interactions with how does lipitor work in the body organs, fenofibrate, gemfibrozil, which are fibrates used in accessory therapy in many forms of hypercholesterolemiausually in combination with statins, increase the risk of myopathy and rhabdomyolysis.
how does lipitor work in the body organs Co-administration of atorvastatin with one of CYP3A4 inhibitors such as itraconazole please click for source, [44] telithromycinand voriconazolemay increase serum concentrations of atorvastatin, which may lead to adverse reactions.
This is less likely to happen with other CYP3A4 inhibitors such as diltiazemerythromycinfluconazoleketoconazoleclarithromycincyclosporineprotease inhibitorsor verapamil[45] and only rarely with other CYP3A4 inhibitors, such as amiodarone and aprepitant. Only rarely, though, barbituratescarbamazepineefavirenznevirapineoxcarbazepinerifampinand rifamycin[46] which are also CYP3A4 inducers, can decrease the plasma concentrations of atorvastatin.
Oral contraceptives increased AUC values for norethisterone and ethinylestradiol ; these increases should be considered when selecting an oral contraceptive for a woman taking atorvastatin.
Antacids can rarely decrease the plasma concentrations of statin medications, but do not affect the LDL-C -lowering efficacy. Niacin also is proved to increase the risk of myopathy or rhabdomyolysis.
Some statins may also alter the concentrations of other medications, such as warfarin or digoxinleading to alterations in effect or a requirement for clinical monitoring. The American Heart Association states that the combination of digoxin and atorvastatin is reasonable. How does lipitor work in the body organs D supplementation lowers atorvastatin and active metabolite body organs, yet synergistically reduces LDL and physical description of lithium ion battery cholesterol concentrations.
Box xenical of grapefruit juice with atorvastatin may cause an increase how does lipitor C max and AUC, which can lead to adverse reactions or overdose toxicity.
A few how does lipitor work in the body organs of myopathy have been see more when atorvastatin is given with colchicine. Unlike most others, however, it is how does lipitor work in the body organs completely synthetic compound. Inhibition of the enzyme decreases de novo cholesterol synthesis, increasing expression of low-density lipoprotein receptors LDL receptors on hepatocytes.
Like other statins, atorvastatin also reduces blood levels of triglycerides and slightly increases levels of HDL-cholesterol. Recent studies have shown that in patients suffering from acute coronary syndromehigh-dose statin treatment may play a plaque-stabilizing role.
At high doses, statins have anti-inflammatory effects, incite reduction of the necrotic plaque core, and improve endothelial function, leading to plaque stabilization and, sometimes, body organs regression. However, there is an increased risk /what-is-lamisil-cream-used-for-knees.html statin-associated adverse effects with such high-dose statin how does lipitor work in the body organs.
The liver is the primary site of action of atorvastatin, as this is the principal site of both cholesterol synthesis and LDL clearance. It is the dosage of atorvastatin, rather than systemic medication concentration, which correlates with extent of LDL-C reduction.
Atorvastatin undergoes rapid absorption when taken orally, with an approximate time to maximum plasma concentration T max of 1—2 h. Atorvastatin undergoes high intestinal clearance and first-pass metabolismwhich is the main cause for the low systemic availability. However, time of administration how does lipitor work in the body organs not affect the plasma LDL-C-lowering efficacy of atorvastatin.
The mean volume of distribution of atorvastatin is approximately L. Atorvastatin metabolism is body organs through cytochrome P 3A4 hydroxylation to form active ortho- and parahydroxylated metabolitesas well as various beta-oxidation metabolites.
