Background/Objectives: Nanoemulsions and microemulsions are promising drug delivery systems capable of enhancing the solubility, stability, and bioavailability of active pharmaceutical ingredients, particularly for central nervous system (CNS) disorders. This study presents a bibliometric analysis of scientific publications on intranasal nanoemulsions from 2004 to 2024, based on data from the Scopus database. Methods: A total of 379 articles were analyzed using Bibliometrix and VOSviewer to identify publication trends, leading countries and institutions, prominent journals, and keyword networks. Results: Publications grew significantly over the last decade, with India, the United States, and China leading in volume. Keyword analysis revealed strong thematic clusters related to “brain targeting,” “drug delivery,” and “intranasal administration,” highlighting this route’s potential for bypassing the blood–brain barrier. The most studied compounds included curcumin, quercetin, carbamazepine, diazepam, and insulin, each with therapeutic applications in neurodegenerative and psychiatric disorders. Conclusions: The findings highlight growing interest in intranasal nano- and microemulsions as a non-invasive and efficient CNS delivery strategy. Future research can bridge translational gaps, enhancing efficacy and safety while meeting regulatory expectations for patient-centered drug development. This study provides a comprehensive overview of current trends and serves as a guide for advancing innovative intranasal delivery platforms.
