The term "pharmaceutical industry" refers to a broad range of companies and organizations involved in the research, development, production, marketing, and distribution of medications or drugs. This includes both prescription drugs that require a doctor's order as well as over-the-counter (OTC) medicines that can be purchased without a prescription. The pharmaceutical industry plays an important role in advancing medical science by developing new treatments and therapies for various diseases, conditions, and injuries. It is also responsible for ensuring the quality, safety, and efficacy of its products before they are made available to consumers.
