Vasoconstriction leads to decreased absorption, lower peak blood levels and decreased duration.
For use before wound cleaning and for repairing superficial scalp and facial lacerations. A less concentrated solution has been suggested for pediatric face and scalp repair. Inhibits conduction of nerve impulses from sensory nerves. When a laceration or abrasion is present, the absorption is much better than when the skin is intact. However, the incidence of side effects also increases.
