Atorvastatin is a selective inhibitor of HMG-CoA reductase, the key enzyme responsible for cholesterol synthesis in the liver. By inhibiting this enzyme, atorvastatin reduces hepatic cholesterol production and increases LDL receptor activity, leading to enhanced clearance of LDL cholesterol from the bloodstream.
Stacor should not be used in patients with:
100% Genuine Products, Guaranteed
Safe & Secure Payments, Always
Fast, Secure & Efficient Delivery
Proper Packaging
Stacor is prescribed as an adjunct to dietary modification and lifestyle changes to manage lipid disorders when non-pharmacological measures alone are insufficient. It is used to:
Absorption
Rapidly absorbed after oral administration
Peak plasma levels achieved within 1–2 hours
Absolute bioavailability of parent drug is approximately 14%
Systemic inhibitory activity reaches about 30%
Distribution
Mean volume of distribution: ~381 L
Approximately 98% protein-bound
Limited penetration into red blood cells
Likely excreted into breast milk based on animal studies
Metabolism
Extensively metabolized into active ortho- and para-hydroxylated metabolites
Metabolism primarily via CYP3A4
Active metabolites contribute approximately 70% of HMG-CoA reductase inhibitory activity
Excretion
Eliminated mainly through bile
Plasma half-life of atorvastatin: ~14 hours
Functional inhibitory half-life: 20–30 hours
Less than 2% excreted unchanged in urine
Primary Hypercholesterolemia & Mixed Hyperlipidemia
Familial Hypercholesterolemia
Prevention of Cardiovascular Events
General Guidelines
Elderly: Higher plasma concentrations; enhanced LDL-C reduction observed
Pediatric patients: Limited pharmacokinetic data available
Renal impairment: No dose adjustment required
Hemodialysis: Clearance not significantly affected
Hepatic impairment: Markedly increased drug exposure in chronic liver disease
Other interactions include:
Pregnancy
Contraindicated during pregnancy
May interfere with fetal cholesterol synthesis
Treatment should be stopped immediately if pregnancy occurs
Lactation
Contraindicated during breastfeeding
Potential risk of serious adverse effects in infants
Liver function tests should be performed before starting therapy and periodically thereafter
Use cautiously in patients with alcohol use or liver disease
Discontinue treatment if severe muscle symptoms or significantly elevated CK levels occur
Store in a cool, dry place
Protect from light and heat
Keep out of reach of children
