Methocarbamol Degradation in Aqueous Solution

Journal of Pharmaceutical Sciences, 1994
The kinetics of the hydrolysis of methocarbamol to the corresponding diol guaifenesin in aqueous solution was studied. Methocarbamol was rather stable in acidic media but easily hydrolyzed in alkaline solution. The formation of an unknown compound, proved to be an isomer of methocarbamol [the 3-(2-methoxyphenoxy)-propanediol 2-carbamate] is involved ...
