Merck & Co Inc

PAR:MRK

Merck & Co. is a global drug company that makes prescription medicines, vaccines, and animal health products. Its best-known business is developing and selling branded drugs for cancer, infectious disease, diabetes, and other serious conditions. It also sells vaccines and medicines used by veterinarians and livestock producers. The company makes money by selling these products to hospitals, pharmacies, doctors’ offices, governments, and animal health distributors. In human health, a large part of the business depends on patented medicines that are approved by regulators and sold through the healthcare system. In animal health, it earns revenue from products that help prevent disease and treat animals on farms and in companion-animal care. Merck stands out because it is not a generic drug maker or a healthcare insurer. It is a research-driven company that spends years developing medicines, getting them approved, and protecting them with patents. That means its business depends on scientific success, regulatory approval, and the ability to keep key drugs and vaccines on the market for many years.
