[Determination of chlorzoxazone and paracetamol in co-chlorzoxazone tablet by multi-wavelength linear regression method].

This paper reports that the contents of chlorzoxazone and paracetamol in the co-chlorzoxazone tablet may be determined by the multi-wavelength linear regression method. The program was edited by BASIC. The average recovery and RSD of chlorzoxazone and paracetamol were 98.67%, 0.34% and 100.05%, 0.31% (n = 5), respectively. This method is simple and rapid with satisfactory results.
