An Insight into Anticorrosive Profiling of Drugs

Abstract

Drugs play an important role for the wellness of communities all over the world. In addition, their potential cannot be ignored for commercial point of view especially as anticorrosive agents. We have done an intensive study for drugs such as antibiotic, anti-inflammatory, antihistamine, antifungal, antibacterial, antihypertensive, antidiabetic and other categories, to explore their potential as anti-corrosive agents against various metals. These drugs have been studied in acidic environments such as HCl, H2SO4, H3PO4, and NaCl against a variety of metals including mild steel, carbon steel, aluminum, copper, iron, zinc, and their alloys. The outcome of our study revealed that drugs are equally effective as corrosion inhibitors. Furthermore, comparative studies of several drug categories revealed that antibiotic and anti-inflammatory drugs demonstrated significant potential of metal protection from corrosion and hence can be used for commercial purpose. The futuristic approach of our work is to give it an extension to the expired drugs’ domain which contribute to the solid waste all over the world. Moreover, new dimension can be given to pharmaceutical and paint industries for the use of expired drugs as corrosion inhibitors.
