In terms of region, the global asthma therapeutics market has been segmented into five key regions: Asia Pacific, North America, Europe, Latin America, and Middle East & Africa. North America is expected to dominate the market due to greater awareness and higher prices of asthma drugs. Asia Pacific is anticipated to hold the second largest share due to high prevalence of asthma in countries such as China and India. China is estimated to account for the largest share of the asthma therapeutics market in Asia Pacific owing to factors such as improvement in diagnosis rate, rapidly aging population, increase in smokers, and high levels of pollution. Major players in the global asthma therapeutics market include Astrazeneca plc, Boehringer Ingelheim GmbH, F Hoffmann-La Roche Ltd., GlaxoSmithKline plc, Merck & Co. Inc., and Novartis AG.
