Despite rapidly evolving health-care systems, India continues to have a high disease burden for asthma and chronic obstructive pulmonary disease (COPD). The Asia-Pacific Asthma Insights and Management survey clearly revealed that asthma management remains very poor with worst clinical outcomes in India. Potent inhaled corticosteroids (ICS) and quick onset of long-acting beta2-agonist (LABA) are considered to be optimal dual therapy for management of asthma and COPD. Fluticasone's long-term action against inflammation and formoterol's rapid long-term bronchodilator action are vital clinical attributes for optimal asthma maintenance treatment. In an 8- and 12-week trial, dual therapy of fluticasone and formoterol (FF) reported lung function improvements and better control of asthma than its monotherapy. A large clinical study revealed mild adverse events of dual FF than other dual ICS-LABA combinations. Recent pooled analysis of asthma showed that fluticasone shares a lower risk of pneumonia in asthma. Dual ICS-LABA therapies are preferred in COPD individuals with history of exacerbations. Numerous clinical studies showed significant efficacy, dose adjustments/switching, and safety outcomes with dual FF therapy in asthma and COPD. Dual FF inhaler therapy ensures highly potent anti-inflammatory activity and sustained bronchodilation, thus making this a preferred combination in terms of efficacy, safety, and patient adherence in asthma and COPD. This present review focuses on the combination therapyof formoterol and fluticasone for managing asthma and COPD.
