A review of mometasone furoate / formoterol in the treatment of asthma.

Asthma is a common chronic respiratory disease affecting the airways causing inflammation, airway hyperreactivity (AHR), and respiratory symptoms. Frequently, asthma can be effectively treated with inhaled corticosteroids (ICS) but in more severe cases additional drugs are required, such as long-acting β2-agonists (LABA). Mometasone furoate (MF) is a synthetic steroid exhibiting a strong affinity for the glucocorticoid receptor as well as a low bioavailability and a high plasma protein binding. In most cases, MF only requires once daily administration. Formoterol fumarate (F) is a full β2-agonist with a rapid onset and 12 h of duration. The present paper reviews the current knowledge of the novel combination of MF and F for the treatment of asthma. Furthermore, a description of the individual components is included. At present, only few clinical studies of MF/F are available for review and more studies of MF/F efficacy are needed, especially comparative studies on other ICS/LABA drugs. However, it does not appear from the reviewed literature that MF/F or its individual components are inferior to other equivalent treatments.
