Development and Validation of analytical method for simultaneous estimation of Econazole and Triamcinolone by RP- HPLC

Key Points

The method demonstrates linear responses in the concentration range of 5-25 mg/ml for Econazole and 45-225 mg/ml for Triamcinolone.
Retention times are 2.090 minutes for Econazole and 5.289 minutes for Triamcinolone under specified conditions.
Validation shows a method precision below 2.0% RSD, ensuring reliable measurements of both drugs.
Chromatography was performed on an X-Terra C18 column with a specific mobile phase composition, highlighting its methodological rigor.

Abstract

А Rаpіd аnd Pгеcіsе Rеvегsе Phаsе Hіgh Pегfoгmаncе Lіquіd Chгomаtogгаphіc mеthod hаs bееn dеvеlopеd foг thе vаlіdаtеd of Econozole & Triamcinolone, іn іts puге foгm аs wеll аs іn tаblеt dosаgе foгm.
