With rapidly increasing air pollution across the globe, especially in urban and industrial hubs, there has been an alarming rise in the incidence of asthma and other respiratory illnesses all around the world. According to conservative estimates, at present around 300 million people in the world are in need of asthma treatment, and this number is expected to rise by another 100 million by 2025.
The characteristic feature of Asthma is an excessive reactivity of the respiratory system (main wind pipe and its numerous branches) to a variety of external stimuli resulting in their narrowing and constriction along with increased secretions. These changes result in the following typical symptoms:
There may be an initial constriction feeling in the chest prior to the actual onset of symptoms. The common allergens that provoke an asthma attack include dust, pollen, moulds, change of weather, pet animals, chemicals in air or food, tobacco smoke, stress, etc.
Traditionally, asthma treatment involves the use of bronchodilators, steroids, and nebulising agents (in oral, inhaler or injectable forms) to relieve the constriction and narrowing. These asthma treatments help in achieving a certain degree of control over the symptoms. However, there is no conventional asthma treatment to reduce the excessive reactivity or sensitivity of the airways.
