Neither the kinetics of the hydrophilic beta-adrenoceptor blocker atenolol nor those of the lipophilic metoprolol were influenced by the concurrent administration of amitriptyline. Compared with placebo, chronic administration (14 days) of atenolol and metoprolol (each as monotherapy) did not significantly reduce oxidative liver metabolism as measured by antipyrine half-life and by 6-beta-hydroxycortisol excretion. Compared with atenolol and metoprolol monotherapy, chronic administration of amitriptyline concurrently with each of the beta-adrenoceptor blockers produced an insignificant decrease (circa 10-20%) in antipyrine half-life and 6-beta-hydroxycortisol excretion. Amitriptyline appears therefore to have little enzyme-inducing activity.
亲水性β-肾上腺素能阻滞剂阿替洛尔及亲脂性美托洛尔的动力学均不受同时给予阿米替林的影响。与安慰剂相比,阿替洛尔和美托洛尔(均作为单一疗法)长期给药(14天)并未显著降低以安替比林半衰期和6-β-羟基皮质醇排泄量衡量的肝脏氧化代谢。与阿替洛尔和美托洛尔单一疗法相比,阿米替林与每种β-肾上腺素能阻滞剂同时长期给药,使安替比林半衰期和6-β-羟基皮质醇排泄量出现不显著的降低(约10%-20%)。因此,阿米替林似乎几乎没有酶诱导活性。
