Respiratory drugs are prescribed for the treatment of asthma and COPD (chronic obstructive pulmonary diseases such as emphysema and chronic bronchitis.) Bronchodilators open bronchial tubes and are administered by injection or aerosol inhalers. Steroid drugs are inhaled or given intravenously and orally to reduce chronic inflammation in respiratory passageways. Leukotriene modifiers are recent additions to the anti-inflammatory therapy of asthma. They prevent asthma attacks and bronchospasms by blocking leukotriene (bronchoconstrictor) from binding to receptors in respiratory tissues.
Examples of respiratory drugs are given below:
albuterol (Proventil, Ventolin HFA)*
formoterol + budesonide (Symbicort)†
ipratropium + albuterol (Combivent)*
salmeterol + fluticasone (Advair Diskus)†
tiotropium bromide (Spiriva)‡
STEROIDS: INTRAVENOUS OR ORAL
