DULERA (formoterol fumarate)

Respiratory Approved 2010-06-22

Dulera is a fixed-dose combination of mometasone furoate and formoterol fumarate indicated for the twice-daily treatment of asthma in patients 5 years of age and older. It is intended for patients whose asthma is not adequately controlled on a long-term asthma-control medication, such as an inhaled corticosteroid (ICS), or whose disease severity warrants the initiation of both an ICS and a long-acting beta2-adrenergic agonist (LABA). Dulera is a maintenance therapy and is not indicated for the relief of acute bronchospasm.

How DULERA Works

Dulera combines the anti-inflammatory activity of mometasone furoate with the bronchodilatory effects of formoterol fumarate. Mometasone furoate is a synthetic corticosteroid that inhibits multiple cell types (e.g., mast cells, eosinophils, lymphocytes) and mediators (e.g., histamine, cytokines) involved in the asthmatic inflammatory response. Formoterol fumarate is a long-acting selective beta2-adrenergic receptor agonist that relaxes bronchial smooth muscle, improving airflow. Together, these components address both the underlying airway inflammation and the physiological bronchoconstriction associated with asthma.
