Dequalinum is an anti-infective and antiseptic agent belonging to the class of quaternary ammonium compounds. The primary mechanism of action is an increase in bacterial cell permeability and the subsequent loss of enzyme activity, finally resulting in cell death.

Lidocaine, like other local anaesthetics, causes a reversible blockade of impulse propagation along nerve fibres by preventing the inward movement of sodium ions through the nerve membrane. Local anaesthetics of the amide-type are thought to act within the sodium channels of the nerve membrane.
