A pharmaceutical company is a business entity that specializes in the research, development, manufacturing, and marketing of pharmaceutical drugs or medications. These companies play a crucial role in the healthcare industry by producing medications that prevent, treat, or manage various diseases and medical conditions. Pharmaceutical companies typically employ scientists, researchers, pharmacists, and other professionals who work together to discover and develop new drugs, conduct clinical trials to test their safety and efficacy, and obtain regulatory approval for their products. Once approved, pharmaceutical companies manufacture the medications in large quantities and distribute them to healthcare providers, pharmacies, and patients worldwide. Additionally, pharmaceutical companies may also engage in activities such as biotechnology, medical devices, and over-the-counter (OTC) products.
