A pharmaceutical company is a business that develops, produces, and markets medications. These companies conduct research to discover new drugs and improve existing ones, ensuring they are safe and effective for patients. They often work closely with scientists and healthcare professionals to bring innovative treatments to the market. Pharmaceutical companies play a crucial role in public health by providing essential medicines for various diseases and conditions. They are also involved in clinical trials, which test new drugs on volunteers to gather data on their safety and effectiveness before they can be approved for widespread use by regulatory agencies like the FDA.
