Should not yet change beta-blocker selection in thyrotoxicosis; leaves open whether potency differences affect outcomes.
Does propranolol have different beta-adrenoceptor blocking activity compared to MJ 1999 in healthy volunteers and patients with thyrotoxicosis?
Propranolol demonstrates greater beta-adrenoceptor blocking activity than MJ 1999 against isoprenaline-induced tachycardia and in thyrotoxicosis, though effects on resting and exercise heart rate are similar.
Ekue et al. (1970) studied this question.
