Amides are named according to the same system as other organic compounds, with the suffix-amide used to designate the presence in the molecule of an amide group. The first step is to consider the number of carbon atoms forming a chain.
Tip. An easy way to remember which local anesthetics are amides is to keep in mind that all of the amide agents have an I in their names, besides the I in the 'caine ending. Local anesthetics tend to be basic compounds, with pKa's ranging from 7.6 to 8.9, and are poorly soluble in water.
