Historically, this approach required the use of separate inhalers; however, the recent advent of \"single-inhaler triple therapy\" (SITT) provided a valuable alternative. One such formulation is the extrafine combination of beclomethasone dipropionate (BDP), fluticasone furoate (FF), and glycopyrronium bromide (GB), which is delivered via a single pressurized metered-dose inhaler (pMDI). Clinical trials, including the TRIMARAN and TRIGGER studies, alongside subsequent post-hoc analyses, have elucidated the benefits of this SITT at both 87/5/9 μg and 172/5/9 μg dosing regimens administered daily. Findings indicated a significant improvement in respiratory function and a reduction in the frequency of exacerbations among patients with uncontrolled asthma. The BDP/FF/GB SITT confirmed efficacy and safety across various ethnic groups (including Caucasian, Japanese, and Chinese populations) and across different age cohorts (adults and adolescents), although it still remains unapproved for individuals under 18 years of age. The use of a single pMDI facilitates the deposition of extra- fine particles from all three active ingredients in the small airways enhancing therapeutic effectiveness. Moreover, the consolidation of medications into one device may improve patients' adherence by mitigating the risks associated with device mismanagement and ensuring optimal drug delivery.
