Oxygen present in the environment is very crucial for a lot of processes to take place, but not necessarily in a positive manner every time. Like in pharmaceutical and Food industries oxygen is not a friend but a foe. After hydrolytic degradation, oxidative degradation is one of the most common modes of degradation addressed by formulators to protect a drug. In contrast to hydrolysis, oxidative mechanisms are complex and often trigger irreversible degradation of the drug compound once initiated.
