 |  | Atorvastatin Usage And Synthesis |  
 | Definition | ChEBI: Atorvastatin is a dihydroxy monocarboxylic acid that is a member of the drug class known as statins, used primarily for lowering blood cholesterol and for preventing cardiovascular diseases. It has a role as an environmental contaminant and a xenobiotic. It is an aromatic amide, a member of monofluorobenzenes, a statin (synthetic), a dihydroxy monocarboxylic acid and a member of pyrroles. It is functionally related to a heptanoic acid. It is a conjugate acid of an atorvastatin(1-). |  | Clinical Use | Hyperlipidaemia and hypercholesterolaemia |  | Drug interactions | Potentially hazardous interactions with other drugs
 Anti-arrhythmics: concentration possibly increased 
by dronedarone.
 Antibacterials: azithromycin, erythromycin, 
clarithromycin or fusidic acid possibly increased 
risk of myopathy - avoid atorvastatin for at least 
7 days after fusidic acid stopped; concentration 
increased by clarithromycin - do not exceed 20 mg 
of atorvastatin1
; avoid with telithromycin; increased 
risk of myopathy with daptomycin; concentration 
possibly reduced by rifampicin. 
 Anticoagulants: may transiently reduce anticoagulant 
effect of warfarin. 
 Antifungals: increased risk of myopathy with 
itraconazole - do not exceed 40 mg of atorvastatin1
;  
increased risk of myopathy with fluconazole, 
ketoconazole, posaconazole, voriconazole and 
possibly other imidazoles and triazoles - avoid. 
 Antivirals: increased risk of myopathy with 
atazanavir, boceprevir (reduce atorvastatin dose), 
and possibly darunavir, fosamprenavir, indinavir, 
lopinavir, ritonavir, saquinavir or tipranavir (max 
dose of atorvastatin 10 mg); concentration reduced 
by efavirenz and possibly etravirine; avoid with 
dasabuvir, ombitasvir, paritaprevir and telaprevir; 
possible increased risk of myopathy with ledipasvir 
- reduce atorvastatin dose; concentration increased 
by simeprevir - consider reducing atorvastatin 
dose. 
 Calcium channel blockers: concentration increased 
by diltiazem - increased risk of myopathy; 
concentration of verapamil increased also possible 
increased risk of myopathy - consider reducing 
atorvastatin dose. 
 Ciclosporin: increased risk of myopathy - do not 
exceed 10 mg of atorvastatin.1 Cobicistat: reduce atorvastatin dose. 
 Colchicine: possible increased risk of myopathy. 
 Grapefruit juice: concentration possibly increased. 
 Lipid lowering agents: increased risk of myopathy  
with fibrates, gemfibrozil (avoid) and nicotinic acid. |  | Metabolism | Atorvastatin undergoes extensive presystemic clearance 
in gastrointestinal mucosa and/or hepatic first-pass 
metabolism. Atorvastatin is metabolised by cytochrome 
P450 3A4 to ortho- and parahydroxylated derivatives 
and various beta-oxidation products. These products are 
further metabolised via glucuronidation. Approximately 
70% of circulating inhibitory activity for HMG-CoA 
reductase is attributed to active metabolites.
Atorvastatin is eliminated primarily in bile as active 
metabolites following hepatic and/or extrahepatic 
metabolism, but does not appear to undergo significant 
enterohepatic recirculation. |
