Stability-indicating assay for tolmetin sodium in solid dosage forms.
A spectrophotometric assay for determining tolmetin sodium in pharmaceutical solid dosage forms is described. Tolmetin sodium is separated from common pharmaceutical excipients and probable degradation products. Recovery, precision, and accuracy data are provided. Two TLC methods are included which can be used to monitor qualitatively the stability of aged dosage forms.
