A hydroxylated amide. Organic amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx).

Oxetacaine improves common gastrointestinal symptoms. Oxetacaine is part of the anesthetic antacids which increase the gastric pH while providing relief from pain for a longer period of duration at a lower dosage. This property has been reported to relieve the symptoms of hyperacidity. Oxetacaine is reported to produce a reversible loss of sensation and to provide a prompt and prolonged relief of pain. In vitro, oxetacaine was showed to produce an antispasmodic action on the smooth muscle and block the action of serotonin. The local efficacy of oxetacaine has been proven to be 2000 times more potent than lignocaine and 500 times more potent than cocaine. Its anesthetic action produces the loss of sensation which can be explained by its inhibitory activity against the nerve impulses and de decrease in permeability of the cell membrane.

Oxetacaine inhibits gastric acid secretion by suppressing gastrin secretion. Moreover, oxetacaine exerts a local anesthetic effect on the gastric mucosa. This potent local anesthetic effect of oxetacaine may be explained by its unique chemical characteristics in which, as a weak base, it is relatively non-ionized in acidic solutions whereas its hydrochloride salt is soluble in organic solvents and it can penetrate cell membranes. Oxetacaine diminishes the conduction of sensory nerve impulses near the application site which in order reduces the permeability of the cell membrane to sodium ions. This activity is performed by the incorporation of the unionized form into the cell membrane.

Oxetacaine is rapidly and extensively metabolized hepatically. After metabolism, there is a formation of primary metabolites such as beta-hydroxy-mephentermine and beta-hydroxy-phentermine. The major metabolites are found in the plasma in insignificant amounts.
