The generic drugs industry comprises of the manufacture and marketing of certain drugs which have the same active ingredients as the brand-name drugs manufactured by any pharmaceutical company. The major benefit of generic drugs is that the cost of such drugs is much less than that of branded drugs. Generic drugs come under the same governing framework as that of the brand-name drugs. The rationale behind generic drugs is that the patented drugs generally have a patent life of 20 years. However, the patent life of such drugs begins from the clinical trials and thus their commercial life is far less (approximately 15 years). After the patent expiry the manufacturers of such drugs face intense pricing pressure because of the competition from their cheap generic counterparts.
