Voltammetric behaviour of ketorolac and its HPLC-EC determination in tablets
Ketorolac is an antiinflammatory-analgesic agent that is oxidizable at the glassy carbon electrode. The voltammetric oxidation produces two well resolved pH-dependent peaks, that are overlapped at pH>10. Using this voltammetric response a HPLC procedure with electrochemical detection in order to quantify ketorolac in pharmaceutical dosage forms is presented. Furthermore comparative methods using UV spectrophotometry and HPLC with photodiode array detector were used.
