ABSTRACT

Asthma is a major and increasing global health problem and, despite major advances in therapy, many patients' symptoms are not adequately controlled. Asthma is a chronic inflammatory condition. Treatment with combination inhalers, which contain a corticosteroid and long-acting beta2 adrenoreceptor agonist, is the most effective current therapy. There is therefore a search for new therapies, particularly safe and effective oral treatments and those that are more efficacious in severe asthma. Environmental factors that may lead to asthma include air pollution; genetic factors, the hygiene hypothesis,and lifestyle differences also play potentially causative roles. Asthma chronic disease involving the airways in the lungs. These airways, bronchial tubes allow air to come in and out of lungs. If you have asthma your airways are always inflamed, they become even more swollen and the muscle around the airways can tighten when something triggers symptoms such as coughing, wheezing, shortness of breath and chest tightness. Smoking is considered to be the single most important preventable risk factor for respiratory symptoms.
