The FDA has approved an inhaled fixed-dose combination (Breo Ellipta – GSK/Theravance) of the corticosteroid fluticasone furoate and the long-acting beta₂-adrenergic agonist (LABA) vilanterol trifenatate for once-daily treatment of chronic obstructive pulmonary disease (COPD).

A little more than a year ago, The Medical Letter reported the results of an FDA meta-analysis which found that use of a long-acting beta-2 agonist (LABA) such as salmeterol (Severent) or formoterol (Foradil) in patients with asthma was associated with an increased risk of a composite endpoint of asthma-related death, intubation or hospitalization; the highest risk was in children 4-11 years old.There was no significant increase in risk when a long-acting beta-2 agonist was used with an inhaled corticosteroid.The Medical Letter recommended that long-acting beta-2 agonists should not be used as...

Tiotropium bromide, an inhaled long-acting anticholinergic available since 2004 as a dry powder inhaler (Spiriva Handihaler) for once-daily treatment of chronic obstructive pulmonary disease (COPD), has now also been approved in an inhalation spray formulation (Spiriva Respimat – Boehringer Ingelheim). According to the manufacturer, the Respimat device improves delivery of tiotropium to the lungs because, unlike with the Handihaler, it is not dependent on the strength of the patient’s breath intake.

The FDA has approved Incruse Ellipta (GSK), a single-agent inhaler containing the long-acting anticholinergic umeclidinium, for once-daily maintenance treatment of chronic obstructive pulmonary disease (COPD). Umeclidinium was initially approved in combination with the long-acting beta₂-adrenergic agonist vilanterol as Anoro Ellipta.

The FDA has approved the marketing of the Alair Bronchial Thermoplasty System (Asthmatx) for treatment of severe persistent asthma in patients ≥18 years old whose asthma is not well controlled with inhaled corticosteroids and long-acting beta₂-agonists.

The FDA has approved Arnuity Ellipta (GSK), a single-agent inhaler containing the corticosteroid fluticasone furoate, for once-daily maintenance treatment of asthma in patients ≥12 years old. Fluticasone furoate is also available in combination with the long-acting beta₂-agonist vilanterol as Breo Ellipta for treatment of asthma and COPD.

The FDA has approved ensifentrine (Ohtuvayre – Verona), an inhaled phosphodiesterase (PDE) 3 and 4 inhibitor, for maintenance treatment of chronic obstructive pulmonary disease (COPD) in adults. It is the first dual inhibitor of PDE3 and PDE4 to be approved by the FDA, and the first inhaled drug with a new mechanism of action to be approved for treatment of COPD in more than 20 years.

Roflumilast (Daliresp – Forest), an oral phosphodiesterase 4 (PDE4) inhibitor, was approved by the FDA to reduce the risk of exacerbations in adult patients with severe chronic obstructive pulmonary disease (COPD) associated with chronic bronchitis and a history of exacerbations.

The FDA has approved over-the-counter (OTC) sale of inhaled epinephrine (Primatene Mist – Amphastar), a nonselective alpha and beta agonist, for temporary relief of mild symptoms of intermittent asthma in patients ≥12 years old who have been diagnosed with mild intermittent asthma by a healthcare professional. The original version of Primatene Mist, which was approved by the FDA in 1967, was removed from the market in 2011 because the metered-dose inhaler (MDI) contained ozone-depleting chlorofluorocarbon (CFC) propellants; the new MDI contains hydrofluoroalkane (HFA)...
