Over the counter (OTC) drugs are non-prescription medicines, which are sold directly to consumers without any prescription from doctors and other healthcare professionals. The OTC drugs are regulated by governmental bodies to ensure that the ingredients used are safe and effective for use without a physician's supervision. These drugs are regulated by active pharmaceutical ingredients (APIs) not the final product. Dietary supplements are intended to provide nutrients to increase the quantity of consumption or provide non-nutrient chemicals that have biologically beneficial effects to users. These supplements are available across all distribution channels such as pharmacies, grocery stores, shopping marts, online pharmacies, and other retailers. The global over the counter (OTC) drugs & dietary supplements market was valued at $223 billion in 2016 and is expected to reach at $335 billion by 2023, registering a CAGR of 5.9% from 2017 to 2023.
