2-Diethylaminoethyl 4-Butylaminobenzoate (farmocaine, T-caine) is an ester-type local anesthetic drug. Like all ester-type local anesthetic drugs farmocaine is very unstable in the body, and in humans they are rapidly hydrolyzed in the plasma. No direct correlation between the saponification and biological activity of farmocaine and similar local anesthetic esters was found. T-Caine has been used as a spray anesthetization of the throat and as a component of Neoarsen black, Neo-percamin S, topical Neozalocain(R) pasta (benzocaine and farmocaine, Neo Dental Chemical Products, Osaka, Japan) and as a calvital powder in dentistry.
