Mechanism of
Action |
|
Dapiprazole is a selective alpha-adrenergic blocking agent, exerting effects
primarily on alpha1-adrenoceptors. It induces miosis via relaxation
of the smooth dilator (radial) muscle of the iris, which causes pupillary
constriction. It is devoid of cholinergic effects. Dapiprazole also partially
reverses the cycloplegia induced with parasympatholytic agents such as
tropicamide. Although the drug has no significant effect on the ciliary muscle
per se, it may increase accommodative amplitude, therefore relieving the
symptoms of paralysis of accommodation. |

|
Administration |
