When pharmaceuticals are antibiotics, the problem is twofold since the buildup of such compounds in the environment also fuels the development of antibiotic resistance. Building weak structures of biologically active compounds is one way of facilitating the quicker degradation of the drug in the environment after the drug has been excreted from the patient subsequently performing its function. The emergence of the process of photodegradation post-excretion of the pharmaceutical from the patient is one method that is under development, which will facilitate a quicker breakdown of the drug. Another method to enable this is hydrolysis, which is pH-dependent and involves making up of compounds that hydrolyze quicker under certain pH conditions.

The convenience of synthesis, recyclability, inexpensiveness, non-toxicity, high solvent capacity, high biodegradation, low volatile organic character, and environmentally benign nature give DESs an edge over other solvents. Due to the numerous benefits to present environmental concerns and the necessity to replace hazardous solvents, the DESs solvent system is appealing to chemists in recent decades. The most important role played by the DESs showed component interactions via covalent or ionic bonds, and is thus considered a good candidate to replace ionic liquids or traditional solvents.
