The pharmaceutical industry consists of companies that research, develop, market, and distribute drugs for nearly every therapeutic need. These companies in the Drug Manufacturers - Other industry are smaller and more specialized than their counterparts in the Major category. Many of these companies rely on only a couple of drugs and are not nearly as diversified as their larger competitors.
Commercial drug companies are driven by research and patent protection. Developing a drug requires an enormous amount of investment in technology, materials, and time, and can be a risky venture for the company. However, after a new drug is successfully developed, thoroughly tested, and patented, it may be potentially very lucrative, especially if it addresses a common health problem (such as health disease or cancer).
