Vadocaine is an anilide derivative with antitussive and local anaesthetic action. Vadocaine is highly distributed to the respiratory tract. In chemical structure vadocaine resembles lidocaine. According to the serum concentrations and pharmacokinetic parameters, no cumulation of vadocaine was observed. The compound had no effect on blood and urinary parameters measured for safety evaluation. Vadocaine is evidently metabolized in the liver and a remarkable part of the drug and its metabolites are excreted into the bile. Accumulation of radioactivity in the kidneys shows that also renal elimination is important.
