Zoken Uses, Dosage, Side Effects, Food Interaction and all others data.
Zoken, an ester local anaesthetic, blocks the initiation and conduction of nerve impulses by decreasing the neuronal membrane’s permeability to Na ions, which results in inhibition of depolarisation with resultant blockade of conduction.
Zoken is indicated for use as a topical anesthetic. It has a duration of action of approximately 10 minutes and a wide therapeutic window. Patients should be counselled regarding the risks of methemoglobinemia.
