The global interferon drugs market is projected to grow at a rapid pace in the next few years because of advanced method of treatment. Increase in incidence of chronic diseases such as hepatitis-B, hepatitis-C, cancer, multiple sclerosis, and others drives the global interferon drugs market. Currently, over 15 human interferons are available in the market and the number is expected to rise in the next few years. Increase in investments in R&D, rise in funding, and technological advancements are the other factors contributing to the growth of the global interferon drugs market. However, patent expiration of interferon drugs acts as a major restraint of the market. Interferon drugs are expensive, which makes these unaffordable for patients. High pricing is a major concern affecting the availability of the drugs to patients.

These factors hamper the growth of the global interferon drugs market. High cost of R&D also restrains the global market.
