  • Composition for local anesthesia
    Patent number: 8603497
    Abstract: An object of the present invention is to provide a composition for local anesthesia to be added to a local anesthetic drug, the composition showing a sustained local anesthetic effect and having high safety. The object is achieved by a composition for local anesthesia including a drug antagonistic to a systemic action of adrenaline, i.e., an ?2 receptor agonist. The ?2 receptor agonist can be added to a local anesthetic agent together with adrenaline or a salt thereof to reduce the amount of adrenaline to be added as compared to that of adrenaline or a salt thereof alone. As a result, a sustained local anesthetic effect is obtained and local anesthesia can be performed with high safety.
