Study Description
Brief Summary:
The primary objective of this study is to observe if Sibutramine is effective in improving the symptoms and signs of sleep apnea in obese patients. The secondary objectives are to document the effects of Sibutramine on heart rate variability and 24-h arterial pressure values. We hypothesized that sibutramine will improve sleep disordered breathing, cardiac autonomic function and systemic blood pressure in obese patients with obstructive sleep apnea (OSA).

Arms and Interventions

Arm Intervention/treatment
Experimental: 1
The first group received sibutramine 10 mg for the first 4 weeks, at which time consideration of increasing dosage to 15 mg was re-evaluated in the case of insufficient weight loss (< 1.8 kg) over the first month of treatment.
Drug: Sibutramine
The first group received sibutramine 10 mg for the first 4 weeks, at which time consideration of increasing dosage to 15 mg was re-evaluated in the case of insufficient weight loss (< 1.8 kg) over the first month of treatment.
Active Comparator: 2
A standard reference group, which was paired according to age and BMI, received CPAP as a treatment for OSA.
Device: CPAP
