[The therapy of bronchial asthma].

Asthma (Greek word that means "breathlessness" or "open-mouth breath") is a chronic inflammatory disorder of the airways, with extensive infiltration of the airway lumen and wall with eosinophils, mast cells, activated T-lymphocytes. Airway inflammation is associated with airway hyperresponsiveness, recurrent episodes of reversible airflow limitation and respiratory symptoms such as wheezing, chest tightness, breathlessness and cough with mucus production. Curiously, asthma worsens particularly at night and in the early hours of the morning. The current consensus on asthma therapy suggests that pharmacological control of asthma can be achieved with antiinflammatory "controller" medications such as inhaled glucocorticoids and cromones. Short-acting bronchodilators act as "reliever" medications and rapidly reverse acute manifestations of asthma. Asthmatic exacerbations require the repetitive administration of inhaled short-acting beta-2-agonist and the early introduction of oral glucocorticoids. Rarely the severity of exacerbation requires the administration of oxygen (that, if available, is not contraindicated), intravenous bronchodilators, glucocorticoids and epinephryne and mechanical ventilation.
