Pharmacodynamics

R450 is an alpha 1 adrenoreceptor antagonist that acts to tighten the muscle tone in the bladder.

Mechanism of action

R450 is a selective alpha 1 adrenoreceptor antagonist. Research on the management of urinary incontinence suggests that it is most likely an antagonist at alpha-1B and alpha-1D, while it acts as an agonist on alpha-1a.
