Stability

After reconstitution, drops are stable at room temperature for 21 days. Store at room temperature (15°C to 30°C/59°F to 86°F)


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.


Usual Dosage

Adults: Administer 2 drops followed 5 minutes later by an additional 2 drops applied to the conjunctiva of each eye; should not be used more frequently than once a week in the same patient


Administration

Shake container for several minutes to ensure mixing. Instill 2 drops into the conjunctiva of each eye followed 5 minutes later by an additional 2 drops. Administer after the ophthalmic examination to reverse the diagnostic mydriasis.
