Effect of celiprolol treatment in hypertensive patients with sleep apnea.

The effects of a beta-blocker, celiprolol, on sleep and arterial blood pressure (BP) were evaluated during a single-blind study in seven hypertensive patients with sleep apnea. Diurnal ambulatory BP measurements with an automatic cuff-inflation device and polysomnography with simultaneous Finapres BP recording were performed separately on consecutive days at the end of two 21-day treatment periods involving placebo followed by celiprolol (200 mg/day). Age was 59 +/- 2.5 yr (m +/- sem) and body mass index 33.2 +/- 2.3 kg. m-2. Diurnal ambulatory BP was significantly lower with celiprolol than with placebo (systolic 139 +/- 4 vs 152 +/- 5 mmHg, diastolic 86 +/- 2 vs 96 +/- 2 mmHg). The apnea-hypopnea index was similar under celiprolol and placebo (48 +/- 7.4 vs 53 +/- 7.8, respectively), as were the total sleep time and percent of duration of the different sleep stages. Individual average BP values were significantly lower during REM sleep under celiprolol but remained similar under celiprolol and placebo in the other sleep stages. Variability of nocturnal BP (assessed by the SD of distribution of BP variations) was not affected by celiprolol. In conclusion, celiprolol which decreased daytime BP, did not affect sleep pattern or respiratory disturbances, or nocturnal BP variability related to apnea.
