Abstract
Asthma & COPD are the 2 major respiratory diseases that are widespread globally, though big differences between them exist in regard to their pathophysiology and treatment. The main treatment modalities for the two diseases are the inhalation routes of administration. The use of the inhalational routes of administration for the drugs used for the management of asthma and COPD is justified by many advantages such as the low effective dose, faster onset of action and lower systemic side effects. However, some advantages for these routes also exist. The major disadvantage is the technique of use, which many patients do not master even with repeated sessions of teaching by the healthcare providers. Difficulty in applying and following the correct inhalers use was found to be a major reason for patients’ non-adherence and consequently failure of the treatment plan.
