No unequivocal central effects were found with either +/--propranolol (120 mg) or +/--sotalol (240 mg) in acute dosage in normal subjects. Subjective feelings of drowsiness and muzziness were found with sotalol and both sotalol and propranolol caused subjects to feel more troubled. These changes were not accompanied by physiological or behavioural evidence of sedation. Adequate beta-adrenoceptor blockade was achieved as measured by a significant fall in pulse-rate on both active drugs but no other significant peripheral physiological changes occurred.
在正常受试者中,急性剂量的±普萘洛尔(120毫克)或±索他洛尔(240毫克)均未发现明确的中枢效应。使用索他洛尔时发现有嗜睡和头晕的主观感觉,索他洛尔和普萘洛尔都会使受试者感觉更不适。这些变化并未伴有镇静的生理或行为证据。两种活性药物均使脉搏率显著下降,表明实现了充分的β-肾上腺素能受体阻滞,但未发生其他显著的外周生理变化。
