The goal of asthma treatment is to control symptoms, prevent exacerbations, and maintain normal lung function. Management of acute exacerbations in the emergency department is not discussed here.

A combination of the corticosteroid mometasone furoate (Asmanex) and the long-acting beta₂-agonist (LABA) formoterol (Foradil) has become available in a single metered-dose inhaler (Dulera – Schering) for treatment of asthma in patients ≥12 years old. It is the third corticosteroid/LABA combination inhaler to become available for this indication in the US. None of these combinations should be used for initial treatment of asthma or for acute treatment of asthma symptoms.

Continued use of a long-acting beta-2 agonist for treatment of asthma may cause down-regulation of the beta-2 receptor with loss of the bronchoprotective effect from rescue therapy with a short-acting beta-2 agonist. After a large study (SMART) found an increased risk of asthma-related deaths in patients receiving the long-acting beta-2 agonist salmeterol, a boxed warning was added to the labeling of all medications containing a long-acting beta-2 agonist. Now the FDA has completed a meta-analysis of 110 asthma treatment studies in 60,954 patients taking any of the long-acting beta-2 agonist...

The FDA has approved aclidinium bromide (Tudorza Pressair – Forest), an orally-inhaled long-acting anticholinergic, for long-term maintenance treatment of bronchospasm associated with chronic obstructive pulmonary disease (COPD).

The FDA has approved a nebulized suspension of the corticosteroid budesonide for maintenance treatment of persistent asthma in children one to eight years old.

The FDA has approved indacaterol (in´´ da ka´ ter ol; Arcapta Neohaler – Novartis), an inhaled long-acting beta₂-agonist, for once-daily maintenance treatment of airflow obstruction in patients with chronic obstructive pulmonary disease (COPD). Indacaterol is not approved for treatment of exacerbations of COPD or for treatment of asthma. It has been available in Europe as Onbrez Breezhaler since 2009.

Zafirlukast (za fir loo kast; Accolate - Zeneca), the first leukotriene receptor anta-gonist approved by the US Food and Drug Administration, is now being heavily promoted for oral maintenance treatment of chronic asthma in patients more than 12 years old. It is not recommended for treatment of acute asthma.

The FDA has approved the over-the-counter (OTC) sale of Nasacort Allergy 24HR (Sanofi), a triamcinolone acetonide nasal spray previously available only by prescription as Nasacort AQ. The OTC product, which is scheduled to be marketed in the spring of 2014, will be the first corticosteroid nasal spray that can be purchased without a prescription in the US. Nasacort Allergy 24HR is approved for use in patients ≥2 years old with nasal allergy symptoms.

The main goals of treatment of chronic obstructive pulmonary disease (COPD) are to relieve symptoms, reduce the frequency and severity of exacerbations, prevent disease progression, and reduce mortality. GOLD (Global Initiative for Chronic Obstructive Lung Disease) guidelines for treatment of COPD were updated recently. Treatment of acute exacerbations is not discussed here. Drugs available for treatment of COPD are listed in Tables 1 and 3.

Ciclesonide (Omnaris - Sepracor/Nycomed), a once daily corticosteroid nasal spray, is now available for treatment of seasonal allergic rhinitis (SAR) in adults and children ≥6 years old and for perennial allergic rhinitis (PAR) in those ≥12 years old. An orally inhaled formulation of ciclesonide (Alvesco) was recently approved by the FDA for maintenance treatment of asthma, and will be reviewed in a future issue of The Medical Letter
