What does a high dibucaine number Meaning?
A test for differentiation of one of several forms of atypical pseudocholinesterases that are unable to inactivate succinylcholine at normal rates; based on the percentage of inhibition of the enzymes by dibucaine, normal enzyme has a DN of at least 75 and higher, heterozygous atypical enzyme has a DN of 40-70, and …

It is sold under the brand names Cincain, Nupercainal, Nupercaine and Sovcaine.
How is succinylcholine metabolized?
Succinylcholine is rapidly metabolized by plasma cholinesterase in the bloodstream to succinylmonocholine, which is then further hydrolyzed (albeit more slowly) to succinic acid and choline. Approximately 10% of an administered dose is excreted unchanged in the urine.
How long does it take dibucaine to work?
