Abstract:
Objectives: To compare efficacy and safety of rosuvastatin 5 mg every day and 10 mg alternate-day in terms of (1) percentage of change from baseline in serum lipid (2) percentage of patients who achieved LDL-C goal according to NCEP-ATP III guideline (2001), and (3) adverse events rate. Methods: A randomized, open-labeled, cross-over group study that enrolled patients from outpatient department, King Chulalongkorn Memorial Hospital during June 2004 to October 2005. Seventy patients were randomized using block randomization, crossover fashion to receive rosuvastatin 5 mg every day (regimen 1) or rosuvastatin 10 mg alternate-day (regimen 2). Each regimen was administered for a duration of four weeks. Clinical outcomes were evaluated based on (1) percentage of change from baseline in serum LDL-C, TC, TG and HDL-C (2) percentage of patients who achieved LDL-C goal according to NCEP-ATP III guideline, and (3) adverse events rate. Results: Baseline patients characteristics were similar between twol groups (all p > 0.05). Both regimens significantly reduced TC, TG, LDL-C and increased HDL-C from baseline (p < 0.001). Rosuvastatin 5 mg every day reduced LDL-C significantly more than rosuvastatin 10 mg alternate-day (p = 0.003), However, the percentage of patients who achieved LDL-C goal according to NCEP-ATP III guideline was not significantly different between rosuvastatin 5 mg every day and 10 mg alternate-day (p=0.549).There was no significant difference in number of patients who experienced adverse events between rosuvastatin 5 mg every day and 10 mg alternate-day. Conclusion: Rosuvastatin 10 mg alternate-day is an alfernative treatment which can reduce patient's cost of medication. It can be used to treat the patients efficiently to reduce LDL-C and to achieve LDL-C goal as same as rosuvastatin 5 mg every day.
