The method was based on the formation of a fluorescent ion\u2010pair complex between citalopram hydrobromide and eosin Y in the presence of a disodium hydrogen phosphate\/citric acid buffer solution of pH\u20093.4 that was extractable in dichloromethane. The extracted complex showed fluorescence intensity at \u03bb<jats:sub>em<\/jats:sub> = 554\u2009nm after excitation at 259\u2009nm. The calibration curve was linear over at concentrations of 2.0\u201326.0\u2009\u00b5g\/mL. Under optimized experimental conditions, the proposed method was validated as per ICH guidelines. The effect of common excipients used as additives was tested and the tolerance limit calculated. The limit of detection for the proposed method was 0.121 \u03bcg\/mL. The proposed method was successfully applied to the determination of citalopram hydrobromide in commercial dosage forms. The results were compared with the reference RP\u2010HPLC method.
