چکیده

The methods for quantitative determination of meloxicam and mefenamic acid in pharmaceuticals by classic spectrophotometry - zero order derivative, first and second order derivatives spectrophotometry is described, using "peak - peak" (P-P) and "peak - zero" (P-O) measurements. The calibration curves are linear within the concentration range of 4.0 - 14.0 microg/mL for meloxicam and 14.0 - 24.0 microg/mL for mefenamic acid. The procedure is simple, rapid and the results are reliable.
