This has been spurred by HMO s, Medicaid, and Medicare to control costs when giving care to patients. Another factor that contributes to the growth of generic drugs is the expiration of blockbuster drugs. In recent years, pharmaceutical companies have witnessed a growing need to develop and market products in developing and emerging economies. Drug companies have been increasingly using direct consumer ads to market their drugs. Many have advertised in general interest magazines and television with the intention that consumers will ask their physician about a particular drug.
Drug companies use such marketing techniques to build up brand preference from consumers.
In addition, some controversial drugs, such as Viagra, have benefited from free publicity which also helps companies sell more drugs. These favorable demographics will mean increased medical care for this aging group. Drug companies have already capitalized on this trend by introducing drugs that are used by people as they age.
