Abstract
A simple two step synthetic procedure has been developed for the preparation of deuterated lidocaine. The deuterium was incorporated into the 6β²βmethyl group which is a metabolically stable position. The overall yield of the synthetic procedure was 41.3%.

Rheology, acid-base behavior, and kinetics of lidocaine release of carbomerΒ±lidocaine (CΓL) hydrogels are reported. A series of (CΓL) x (x mol% of L 25, 50, 75, 100) that covers a pH range between 5.33 and 7.96 was used. Concentrations of ion pair ([R-COO Γ LH ]) and free species (L) and (LH ) were
Stepwise deuteration of the acidic methylene group of lidocaine (&) on a large scale using a moderate excess of 2H20 in triethylamine/pyridine at 200' is described (Table 1). The efficient and economical preparation of bideuterated lidocaine (2) facilitates the use of this compound as an excellent
