Electrochemical methods have become increasingly popular in the pharmaceutical and drug analysis sectors due to their numerous benefits, such as high sensitivity, selectivity, and specificity. Electrochemical-based nanomaterials are adjustable and can be influenced by the type of electrode used and the applied potential. Electroanalytical methods have proven to be a useful analytical technology that has seen increased utility in the pharmaceutical business in recent years. In the last five years, there have been significant developments in the synthesis and use of novel electrochemical sensors in drug analysis. These developments have been driven by advancements in instrumentation and an increased understanding of electrochemical methods. This review concludes the current state-of-the-art in electrochemical sensors for pharmaceutical analysis and future perspectives in this field. We highlight the need for more standardized methods for the determination of biologically important compounds such as dopamine, guanine, adenine, and uric acid using electrochemical sensors and the development of multiplexed sensors for simultaneous analysis of multiple drugs.
