The control of asthma in both adults and children has proven to be a challenge owing to the intricacy involved in the management of the disease. According to the Global Initiative for Asthma (GINA 1), the term refers to a clinical syndrome of “intermittent respiratory symptoms triggered by viral upper respiratory infections, environmental allergens or other stimuli and is characterized by nonspecific bronchial hyperesponsiveness and airways inflammation.” The severity of the disease is measured based on an individual’s lung function (FEV1), the number of times a patient uses a bronchodilator, and the symptoms a patient portrays at night (GINA 1).
The pathophysiology of Asthma includes bronchoconstriction which is the first step; refers to

Asthma is a common problem in many health institutions and has afflicted many individuals on a global scale. The result is high costs of treating the disease, worsening of the condition and excessive cases of hospital admission. There are several factors that might be related to this situation including the inaccurate utilization of the inhalers that are used to administer drugs such as β-antagonists, corticosteroids, and anticholinergics. However, studies in the medical field depict that there the patients as well as caregivers may not adequately know how to administer the drugs using the inhalers. There is therefore need to establish whether patients are aware how to utilize inhalers.
Various literatures note that emergency departments in hospitals are always filled with asthmatic patients; a situation which is associated with substantial costs of treatment Adams et al. (566) Lenney et al. (496) posit that inefficient use of inhaler or poor technique results in poor delivery of the drug being delivered, a decrease in adequate disease control and therefore the increased use of inhalers. Adams et al. indicate that various studies have shown that excessive beta antagonist use as well as inadequate consumption of anti-inflammatory medication is contributors to excess hospital admissions, poor control of asthma and sometimes death in very severe and acute cases.
