Rapid Color Test Identification System for Screening of Counterfeit Fluoroquinolone
The protocol of rapid identification system consists of three chemical color reactions; two group tests for fluoroquinolone class and a compound specific test each for norfloxacin, ciprofloxacin, gatifloxacin, ofloxacin, levofloxacin and sparfloxacin. The group color reactions are based on (a) Oxidizing behavior of quinolone and (b) Fluorine functional groups, both of which are characteristic of fluoroquinolone class. The compound specific color reactions are developed taking into consideration unique chemical behavior of each compound. The proposed chemical color tests have high selectivity⁄specificity, are ideal for screening purpose. The color of each test was defined by two standard color systems namely CIE lab and Munsell color. A suspected counterfeit tablet of any of the above mentioned drugs can be identified within 10-15 min using this rapid identification system.
