Its structure corresponds to the standard molecule of a hydrophilic and hydrophobic domain separated by an intermediate ester found in most of the local anesthetics. Due to its very low water solubility, butamben is considered to be suitable only for topical anesthesia. The FDA removed all parenteral butamben products from the market, possibly due to the poor solubility of this drug."}]
