- Abstract
Background: Atorvastatin has a longer duration of action than other hydroxymethylglutaryl coenzyme A reductase inhibitors. Objectives: The objective was to evaluate the efficacy of alternate day vs. daily dosing of atorvastatin for the treatment of hyperlipidemia. Materials and Methods: In this prospective, open label, crossover study, 40 patients with plasma low-density cholesterol (LDL-C) of more than 130 mg/dl and total cholesterol (TC) more than 200 mg/dl were recruited. After baseline tests, they were randomly allocated to two groups. Group A received 20 mg atorvastatin on alternate days and group B received 20 mg atorvastatin daily for 12 weeks. After 4 weeks of washout period, the groups were crossed over to the other treatment regimen for another 12 weeks. Fasting plasma lipid profile and serum alanine transaminase (ALT) and aspartate transaminase (AST) were measured for both groups at 6th, 12th, 16th, 22nd, and 28th weeks. Results were pooled across the periods and data between the two groups were compared using unpaired t-test. Results: Among the 40 enrolled subjects, 38 completed the study. Both treatment regimens significantly reduced LDL-C and TC compared to baseline. There was no statistically significant difference between the two groups in terms of reduction of plasma LDL-C and TC at 6 and 12 weeks of treatment. Both the regimens were well tolerated. Conclusion: Alternate-day treatment with atorvastatin is comparable in efficacy and safety to the established daily treatment regimen, thus being a cost effective alternative.
