Wixela Inhub: A Generic Equivalent Treatment Option for Patients with Asthma or COPD.

PURPOSE

The purpose of this review is to discuss the development of Wixela™ Inhub™, a generic equivalent of Advair Diskus, a fixed-dose combination of fluticasone propionate/salmeterol powder for oral inhalation for patients with asthma whose symptoms are not controlled with inhaled corticosteroids alone and for those with chronic obstructive pulmonary disease (COPD) who are at a high risk for exacerbations. We provide an overview of the Inhub device and the bioequivalence studies that have been conducted to date. Briefly, the in vitro performance, improvements in forced expiratory volume in 1 s, and the fluticasone propionate/salmeterol dose strengths for Wixela Inhub and Advair Diskus were comparable.

CONCLUSION

The bioequivalence demonstrated by the totality of clinical and in vitro data supports the use of Wixela Inhub and provides a treatment option for patients with asthma or COPD.
