## Abstract This paper describes the determination of diclofenac (DCF) in pharmaceutical formulations using flow injection method with multiple pulse amperometric detection. Unmodified boron‐doped diamond (BDD) is used as working electrode and 0.10 mol L^−1^ sulfuric acid as supporting electrolyte.
