Effect of celiprolol and metoprolol on lipids, fibrinogen and airways function in hyperlipidaemic hypertensives: a randomised double-blind long-term parallel group trial.

Abstract

The effects of celiprolol 200 mg or 400 mg once daily on blood pressure (BP), serum lipids, plasma fibrinogen and airways function was compared with the effects of metoprolol 100 mg or 200 mg once daily in 171 patients with mild to moderate hypertension and coexistent hyperlipidaemia in a double-blind, multicentre study lasting 1 year. Significant decreases in systolic and diastolic blood pressure and heart rate were observed compared with baseline (DBP: celiprolol -13.3 mm Hg, P < 0.0001; metoprolol -14.3 mm Hg, P < 0.0001; SBP: celiprolol -18.2 mm Hg, P < 0.0001; metoprolol -20.5 mm Hg, P < 0.0001; heart rate celiprolol -4 beats/min, P < 0.003; metoprolol -12 beats/min, P < 0.0001). There was no difference between the effects of the two treatments on BP but celiprolol had less effect on heart rate than metoprolol, (celiprolol-metoprolol 7.3 beats/min, P = 0.0002). When compared with baseline values celiprolol significantly reduced serum low density lipoprotein cholesterol (LDL-C) (-5.8%, P = 0.0401) and produced a slight increase in high density lipoprotein cholesterol (HDL-C) which approached statistical significance (4.1%, P = 0.0659). Metoprolol significantly increased serum triglycerides (32%, P = 0.0001) and the total/HDL-C ratio (7.4%, P = 0.0192). Compared with metoprolol, celiprolol significantly reduced LDL-C (-7.3%, P = 0.0062), total cholesterol (-4.5%, P = 0.0085), apoliproprotein B (-10.1%, P = 0.0001), the apolipoprotein B/A1 ratio (-10.9%, P = 0.0001), the total cholesterol/HDL-C ratio (-10.8%, P = 0.0001) and triglycerides (-24.8%, P = 0.0001), and significantly increased HDL-C (6.0%, P = 0.0043).(ABSTRACT TRUNCATED AT 250 WORDS)
