Adverse reactions

Mechanism of action

Mechanism of Action: Neurozyl™ Cream releases lidocaine from a mild acidic vehicle to stabilize the neuronal membrane by inhibiting the ionic fluxes required for initiation and conduction of impulses, thereby effecting local anesthetic action. A mild acidic vehicle lowers pH to increase protection against alkaline irritants and to provide a favorable environment for healing.
