Research Papers that Mention the Interaction

Practolol (1 nM), a selective beta 1-adrenergic antagonist, but not butoxamine (… microM), a beta 2-adrenergic antagonist, blocked the potentiation by higenamine (5 nM) of the aconitine-induced positive chronotropic effect and, at high concentrations (… and 300 nM) also shifted the aconitine concentration-response curves to the right.

The positive chronotropic effect of higenamine was antagonized by propranolol (30-300 nM) and practolol (10 nM-3 microM), but not by butoxamine (1 microM), indicating that it was a beta 1-adrenoceptor-mediated action.
