The global antiviral drugs market size was valued at USD 36.18 billion in 2018 and is projected to reach USD 58.84 billion by 2026, exhibiting a CAGR of 4.0% during the forecast period based on our analysis in the existing report.

Virus is a particle of RNA or DNA enclosed in a structural protein. They infect the human cells and proliferate to cause viral infections. Viral infection is considered to be one of the most common causes of human illness and has a significant impact on the healthcare system across the globe. The infections spread rapidly in the community and are responsible for considerable morbidity. They can be severe and require a systematic approach for their management. In the developed economies, it is estimated that around 30% to 40% of the infectious gastroenteritis cases are attributable to viruses. Antiviral agents are thus, the therapeutics that restore the normal function of cells and eliminate the viral infection. They generally inhibit the replication of viruses inside the body.

Various pharmaceutical companies are engaged in developing novel antiviral therapies across the globe to prevent the spread of communicable viral infections. Rising burden of viral diseases, especially in the developing nations and improved research collaboration of industries in the development of blockbuster therapeutics are the key factors associated with the market growth. For instance, around 125,000 to 200,000 infections occur annually in the U.S., out of which about 70% of adults are symptomatic, according to the Centers for Disease Control and Prevention. Such increasing prevalence of viral disease is expected to boost the antiviral drugs market size during the forecast period. There are over a thousand different types of viruses that infect humans and they account for around 60% of all human infections. However, lack of rapid diagnostic reagents and the speedy replication of viruses make it difficult to develop potent and effective antiviral therapy.


“Rising Prevalence of HIV and Influenza to Fuel Growth of Market”

HIV is emerging as the most common form of viral infection across the globe. Enhanced surveillance for HIV by using demographic and biological data has improved the diagnosis rate of the disease. According to WHO, around 37.9 million people were living with HIV in the globe in 2018, while 770,000 people died of this disease. Hence, the increasing burden of this infection is boosting the demand for targeted and specific treatment regimen and in-turn propelling the antiviral agents market growth.

Moreover, the rising incidence rate of influenza and its quick diagnosis are contributing to the high demand for antiviral therapeutics across the globe.

“Introduction of Blockbuster Therapeutics to Boost the Market”

Various key pharmaceutical giants are actively investing in the research and development of antiviral agents. The introduction of blockbuster drugs, such as Biktarvy by Gilead Science and Triumeq by GlaxoSmithKline have changed the face of antiretroviral therapy. Rising uptake of such blockbuster agents and their improved distribution by the manufacturers are likely to propel the antiviral market revenue during 2019-2026. Biktarvy received approval in February 2018 and it is targeting the populaces that are living with HIV globally. Out of those, around 21 million people are receiving antiretroviral therapy which allows the immune system to strengthen.


By Drug Class Analysis

“Combination Drugs Segment to Witness Remarkable Growth”

Based on the drug class, the antiviral medication market is classified as protease inhibitors, polymerase inhibitors, integrase inhibitors, combination drugs, reverse transcriptase inhibitors, and others. Out of these, the combination drugs segment accounted for the highest market share in 2018, which is attributable to the remarkable performance of combination brands, such as Genvoya, Mavyret, Triumeq, etc. Also, green signal by USFDA for the launch of novel combination therapies of antiviral medication for flu is anticipated to boost the growth of this segment during 2019-2026.

“Human Immunodeficiency Virus (HIV) Segment to Dominate the Market”

On the basis of disease indication, the antiviral therapeutics market is segmented into hepatitis, human immunodeficiency virus (HIV), influenza, and others. The others segment is further comprised of herpes infection, rotavirus infection, etc. The HIV segment registered the maximum market share in 2018, owing to the rapid rise in the prevalence of HIV infection. Also improved treatment regimen for HIV infection and favorable reimbursement policies for antiretroviral therapy in several countries are anticipated to augment the growth of this segment. It is, in turn, set to impact the market positively during the forthcoming period.  

Participation of the governments in developing economies to promote virology education and to address the unmet need for effective antiviral therapeutics, especially for HIV infection, are improving the collaborative research for antiretroviral drugs. Moreover, the development of comprehensive guidelines on HIV-preventive interventions and evaluation of HIV preventive capacity of drug treatment services by WHO are likely to enhance the demand for HIV drugs during the forecast period.

By Distribution Channel Analysis

“Strong Government Support to Favor the Hospital Pharmacy Segment”

In terms of distribution channel, the market is segmented into hospital pharmacy, retail pharmacy, and online channel. Strong government support for viral diseases through establishment of government-aided hospital pharmacies, favorable reimbursement policies, and improved supply network of key companies are the major factors attributable to the expansion of the hospital pharmacy segment. The online channel segment is expected to register a relatively significant CAGR during the forecast period, due to the emergence of online pharmacy offering discounts and their rapid adoption by the masses. The retail pharmacy segment is anticipated to expand on account of the increasing patient pool and availability of OTC and generic medications for minor viral infections.  


North America, with a revenue of USD 13.9 billion in 2018, accounted for a major antiviral drugs market share. This is attributable to the strategic presence of key pharmaceutical giants in the U.S., increased prevalence of infections such as HIV in the country, and green signal by USFDA for the launch of blockbuster and effective therapies in North America. Europe is anticipated to witness a remarkable growth in the coming years owing to the favorable reimbursement policies for antiviral therapy and key players involved in the R&D of antiviral medication for HIV.
