Mixed dyslipidaemia, Heterozygous familial hypercholesterolaemia, Nonfamilial hypercholesterolaemia
Adult: Initially, 10 or 20 mg once daily, may be adjusted at 4-wk interval. May initiate 40 mg once daily in patients who require>45% reduction in LDL-cholesterol. Max: 80 mg/day.
Child: Heterozygous familial hypercholesterolaemia: 10-17 yr 10 mg once daily, may increase at intervals of at least 4 wk to max 20 mg/day.
Elderly: No dosage adjustment needed.
Atorvastatin can be administered as a single dose at any time of the day, with or without food. Therapy should be individualized according to goal of therapy and response. After initiation and/or upon titration of Atorvastatin, lipid levels should be analyzed within 2 to 4 weeks and dosage adjusted accordingly. Since the goal of treatment is to lower LDL-C, the LDL-C levels should be used to initiate and assess treatment response. Only if LDL-C levels are not available, should total-C be used to monitor therapy.
Dosage in Patients with Renal Insufficiency: Renal disease does not affect the plasma concentrations or LDL-C reduction of atorvastatin; thus, dosage adjustment in patients with renal dysfunction is not necessary.
