Tolerability and effectiveness of every-other-day atorvastatin compared to daily atorvastatin in patients with muscle symptoms: A randomized controlled clinical trial.

ABSTRACT: Despite limited evidence, non-daily dosing of statins is recommended for managing muscle symptoms associated with statin therapy. We assessed the tolerability and effectiveness of every-other-day atorvastatin compared to daily atorvastatin in patients having muscle symptoms associated with atorvastatin therapy. A parallel-group, outcome-assessment-blinded, randomized controlled clinical trial was conducted at Colombo South Teaching Hospital, Sri Lanka. Patients with muscle pain, tenderness or cramps alone or in combination for ≥2 weeks while on daily atorvastatin for ≥1 month, with no alternative cause, were recruited. Patient's regular atorvastatin dose was given every-other-day to those in intervention group (IG) and daily to those in control group (CG). Primary outcomes were assessed at 24 weeks and included composite of myalgia and myositis, LDL-cholesterol level and percentage reduction of LDL-cholesterol from baseline. Number recruited was 49 to IG (women:79.6%; mean-age:60.6 ± 8.7years) and 52 to CG (women:73.1%; mean-age:61.7 ± 9.8years). Mean atorvastatin dose per day was 8.6 mg (SD = 4 mg) and 17.6 mg (SD = 8.4 mg) in IG and CG, respectively. Composite of myalgia and myositis at 24 weeks was 79.6% in IG and 69.2% in CG (OR = 1.7, 95% CI 0.7-4.3; p = 0.234). IG failed to show noninferiority for mean LDL-cholesterol (difference:0.31 mmol/L; upper limit 97.5% CI:0.61 mmol/L; p for noninferiority = 0.989) and for mean percentage reduction of LDL-cholesterol from baseline (difference:3.13%; upper limit 97.5% CI:15.5%; p for noninferiority = 0.718). At 24 weeks, mean creatine kinase and discomfort due to muscle symptoms (assessed with Visual Analogue Scale) were not different between the two groups. Findings of this study do not favor every-other-day atorvastatin as an option for managing patients with muscle symptoms associated with atorvastatin therapy.

Project description:BackgroundWe compared the efficacy and safety of low-intensity atorvastatin and ezetimibe combination therapy with moderate-intensity atorvastatin monotherapy in patients requiring cholesterol-lowering therapy.MethodsAt 19 centers in Korea, 290 patients were randomized to 4 groups: atorvastatin 5 mg and ezetimibe 10 mg (A5E), ezetimibe 10 mg (E), atorvastatin 5 mg (A5), and atorvastatin 10 mg (A10). Clinical and laboratory examinations were performed at baseline, and at 4-week and 8-week follow-ups. The primary endpoint was percentage change from baseline in low-density lipoprotein (LDL) cholesterol levels at the 8-week follow-up. Secondary endpoints included percentage changes from baseline in additional lipid parameters.ResultsBaseline characteristics were similar among the study groups. At the 8-week follow-up, percentage changes in LDL cholesterol levels were significantly greater in the A5E group (49.2%) than in the E (18.7%), A5 (27.9%), and A10 (36.4%) groups. Similar findings were observed regarding the percentage changes in total cholesterol, non-high-density lipoprotein cholesterol, and apolipoprotein B levels. Triglyceride levels were also significantly decreased in the A5E group than in the E group, whereas high-density lipoprotein levels substantially increased in the A5E group than in the E group. In patients with low- and intermediate-cardiovascular risk, 93.3% achieved the target LDL cholesterol levels in the A5E group, 40.0% in the E group, 66.7% in the A5 group, and 92.9% in the A10 group. In addition, 31.4% of patients in the A5E group, 8.1% in E, 9.7% in A5, and 7.3% in the A10 group reached the target levels of both LDL cholesterol < 70 mg/dL and reduction of LDL ≥ 50% from baseline.ConclusionsThe addition of ezetimibe to low-intensity atorvastatin had a greater effect on lowering LDL cholesterol than moderate-intensity atorvastatin alone, offering an effective treatment option for cholesterol management, especially in patients with low and intermediate risks.
