The pharmaceutical or drug industry historically has been one of the most innovative and profitable business sectors in the United States. Recent developments, however, portend major changes in the nation's pharmaceutical industry. Growing regulatory oversight, rising consumer distrust over advertising claims, drug safety concerns, increased cost-containment initiatives by government and private third-party payers, mandated health technology assessments to determine coverage and reimbursement policies, patent expirations of top-selling products, and the implementation of the Medicare Part D drug benefit have influenced changes in the industry's practices and strategies. This entry describes the global sales and market share of the pharmaceutical industry, the different classifications within the industry, and the future outlook for the industry in light of the recent developments.

Global Pharmaceutical Sales

Global pharmaceutical sales grew by 7% in 2006, totaling more than $643 billion (all data reported in U.S. dollars) in sales, according to industry estimates by IMS Health. This marked the third straight year of single-digit revenue growth for the pharmaceutical industry, after 5 years of double-digit increases from 1999 to 2003. The worldwide pharmaceutical market is dominated by the United States, with 44% of the world's market share, followed by Europe, with 28%, Japan, 10%, Asia Pacific, 7%, Latin America, 5%, the Middle East and Africa, 3%, and Canada, 3%. The largest European markets are France, Germany, Italy, the United Kingdom, and Spain. The Asia Pacific region includes fast-growing pharmaceutical companies, located in India and China, which mainly produce generic versions of drug products. Brazil is the largest market in Latin America.

Classification of the Pharmaceutical Industry

The pharmaceutical industry, or pharma, includes three primary sectors: (1) the traditional research-intensive pharmaceutical industry, (2) the research-intensive biopharmaceutical industry, and (3) the generic pharmaceutical industry. These sectors, however, are increasingly becoming blurred because of strategic company acquisitions, mergers, licensing agreements, and other business practices. For example, most traditional research-intensive pharmaceutical companies manufacture or license generic versions of their original products. The traditional research-intensive industry is attempting to gain market share and position in the biopharmaceutical industry. And the generic pharmaceutical industry is lobbying for legislation to facilitate the approval of biogenerics (i.e., similar versions of biotech pharmaceutical products).

Traditional Pharmaceutical Industry

The traditional research-intensive pharmaceutical industry is also known as the “brand-name” or “innovator” pharmaceutical industry. The largest companies in this sector are often referred to as “Big Pharma.” They are represented by the trade association, Pharmaceutical Research and Manufactures of America (PhRMA). This sector focuses on the discovery, development, and production of new chemical entities and new biologic entities. These multibillion dollar corporations, however, are not limited solely to drug products or vaccine sales. Many of these corporations include other healthcare-related products, such as nutrition products, dietary supplements, diagnostics, medical devices, and other consumer products.

Relative rankings of the world's top pharmaceutical companies change yearly due to sales, patent expirations, mergers, acquisitions, and other practices. Based on 2007 rankings (compiled from Fortune 500 lists), 12 pharmaceutical corporations accounted for 60% of the total global pharmaceutical sales. The leading companies-based on sales, headquarters country, revenue, and profit (as a percentage of revenues)-were (1) Johnson & Johnson (U.S.), $53.3 billion, 20.7%; (2) Pfizer (U.S.), $52.4 billion, 36.9%; (3) GlaxoSmithKline (U.K.), $42.7 billion, 23.2%; (4) Novartis (Switzerland), $37 billion, 19.4%; (5) Sanofi-Aventis (France), $37 billion, 13.6%; (6) Roche Group (Switzerland), $34.7 billion, 18.1%; (7) AstraZeneca (U.K.), $26.5 billion, 22.8%; (8) Merck & Co. (U.S.), $22.6 billion, 19.6%; (9) Abbott Laboratories (U.S.), $22.5 billion, 7.6%; (10) Wyeth (U.S.), $20.4 billion, 20.6%; (11) Bristol-Myers Squibb (U.S.), $17.9 billion, 8.8%; and (12) Eli Lilly (U.S.), $15.7 billion, 17%.
