Brief Summary:

The aim of this clinical trial is to evaluate the effect of Atorvastatin on the endothelial function improvement during the obstructive sleep apnea syndrome (OSAS) after 3 months of treatment, by a double-blind, randomized, placebo-controlled, multi-center study.

An interim analysis will be performed when 25 patients per group will be included.


Condition or disease Intervention/treatment Phase
Obstructive Sleep Apnea Syndrome Drug: Atorvastatin treatment Other: CPAP device Other: sham CPAP treatment Phase 2

Detailed Description:

Secondary objectives of this clinical trial :

  • To evaluate the effect of Atorvastatin in comparison with the placebo on the inflammation occurring during OSAS, after 3 months of treatment.
  • To evaluate the effect of Atorvastatin in comparison with the placebo on the insulin-resistance associated to OSAS, after 3 months of treatment.
  • To evaluate the effect of Atorvastatin in comparison with the placebo on the hypercholesterolemia associated to OSAS, after 3 months of treatment.
  • To evaluate at 6 months, the effect of the continuous positive airway pressure (CPAP) + Atorvastatin association on the previously cited parameters, in comparison with Atorvastatin, CPAP and placebo.
  • To measure the CPAP efficiency in comparison with sham CPAP in patients receiving the placebo, after 3 months of treatment.

  2. Evaluation of the insulin-resistance associated to OSAS. [ Time Frame: after 3 months of Atorvastatin or placebo treatment. ]
  3. Evaluation of the hypercholesterolemia associated to OSAS. [ Time Frame: after 3 months of Atorvastatin or placebo treatment. ]
  4. Evaluation of the effect of continuous positive airway pressure (CPAP) + Atorvastatin association on the previously cited parameters, in comparison with effect of Atorvastatin, CPAP and placebo. [ Time Frame: after 6 months of treatments ]
  5. Measurement of the CPAP efficiency in comparison with sham CPAP in patients receiving the placebo. [ Time Frame: after 3 months of treatment. ]
