Mapping the evolution of inhaled drug delivery research: Trends, collaborations, and emerging frontiers

•Bibliometric analysis of data acquired from the Web of Science Core Collection database were assessed via VOSviewer and CiteSpace.•The current state, emerging trends, and newly discovered frontiers of inhaled drug delivery were summarized in this review.•Inhaled drug delivery may potentially impact treatment options for patients not restricted to respiratory diseases. Inhaled drug delivery is a unique administration route known for its ability to directly target pulmonary or brain regions, facilitating rapid onset and circumventing the hepatic first-pass effect. To characterize current global trends and provide a visual overview of the latest trends in inhaled drug delivery research, bibliometric analysis of data acquired from the Web of Science Core Collection database was performed via VOSviewer and CiteSpace. Inhaled drug delivery can not only be utilized in respiratory diseases but also has potential in other types of diseases for both fundamental and clinical applications. Overall, we provide an overview of present trends, collaborations, and newly discovered frontiers of inhaled drug delivery.
