What is Emla?
How does it work?
Emla 5g Cream contains a combination in equal amounts of two anesthetics, lignocaine and prilocaine. These anesthetics are aminoamides that act directly on the nerve endings of the skin to block the generation and transmission of specific nerve impulses in a defined area, and this provides a reversible loss of sensitivity in superficial pain receptors.
Lignocaine and Prilocaine in Emla 5% Cream work by stabilizing nerve cell membranes by blocking the entry of sodium ions through voltage-dependent sodium channels into cell membranes and this inhibits the generation of a nerve impulse and its transmission to the brain, which means that pain receptors will not receive any pain sensation, although other sensations such as pressure can still be perceived. Emla Cream 5% is absorbed through the layers of the skin, reaching the nerve endings and pain receptors, where they work together to numb the skin area before a potentially painful procedure such as an injection.
