Development of a novel voltammetric method for revefenacin determination using modified electrodes in pharmaceutical and biological matrices

Revefenacin (REV) is an inhalation solution used for management of Chronic Obstructive Pulmonary Disease (COPD) in the USA, this is single medication that is an approved bronchodilator delivered by nebulization with a once-daily frequency. Even though the crucial necessity of quality control in pharmaceutical manufacturing, no officially recognized methods exist for REV determination in biological samples. A sensitive, economical, simple and efficient electrochemical procedure using carbon paste
