Why the study?
Do specific plasma levels of racemic and dextro-propranolol suppress chronic, stable ventricular ectopic beats?
Do specific plasma levels of racemic and dextro-propranolol suppress chronic, stable ventricular ectopic beats?
Propranolol suppresses ventricular ectopic beats through its beta-adrenergic blocking activity, with efficacy associated with specific plasma levels of the racemic mixture.
No takes yet. Share an insight, caveat, or question.
Should not yet change practice for ventricular ectopy; supports beta-blockade mechanism and warrants controlled confirmation.
Coltart et al. (1971) studied this question.
