Dibucaine
Dibucaine is a local anesthetic of the amide type now generally used for surface anesthesia. Dibucaine reversibly binds to and inactivates sodium channels in the neuronal cell membrane. Inhibition of sodium channels prevents the depolarization of nerve cell membranes and inhibits subsequent propagation of impulses along the course of the nerve, thereby limiting the excitation of nerve endings. This results in loss of sensation. Dibucaine inhibits normal butyrylcholinesterase activity. The percentage of butyrylcholine that remains unchanged in the blood of individuals administered a standard dose of dibucaine was the dibucaine number. This number was used to differentiate the genetic variants. A dibucaine number of 80 and above for wild type homozygotes (normal), 40-60 for heterozygotes (atypical), and 20 or less for atypical homozygotes (D70G)
