A specific, rapid and simple UV spectrophotometric method with good sensitivity was developed and
validated for the simultaneous quantification of aspirin and paracetamol in standard solutions and
tablets. The method employed solving of simultaneous equations based on the measurement of
absorbance at two wavelengths, 265 and 257 nm, λ max for aspirin and paracetamol, respectively. The
calibration curve was linear for both drugs in a concentration range of 2 to 64 µg/ml. It can be concluded
from the results that present method for the simultaneous determination of aspirin and paracetamol in
tablets is specific, rapid and simple with good sensitivity. This analytical method is also applicable in
ordinary laboratories also. It can also be adopted for quality control tests for these drugs in tablets
