Intranasal Nano-Delivery Systems: Emerging Strategies for Central Nervous System Disease Therapeutics.
Review in International journal of nanomedicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The rising global incidence of central nervous system (CNS) diseases, exacerbated by the formidable blood-brain barrier (BBB) hindering effective drug delivery, necessitates novel therapeutic strategies. Nasal administration has emerged as a promising non-invasive route, bypassing the BBB via direct neural pathways (olfactory/trigeminal), systemic absorption, or lymphatic drainage. However, inherent nasal barriers like the mucus layer and epithelium limit its efficacy. This review distinguishes itself by integrating mechanistic insights into nasal transport pathways with the rational design of advanced nano-delivery systems. We first outline the challenges in CNS drug delivery and detail the nasal anatomy and transport pathways facilitating nose-to-brain delivery. Subsequently, we emphasize the critical properties required of advanced nano-carriers to improve mucosal penetration, prolong retention, and promote drug accumulation at cerebral injury sites. Following a detailed analysis of the advantages and limitations associated with nose-to-brain delivery, we consolidate recent advances in nasal nano-delivery systems for treating CNS disorders, emphasizing their capacity to improve brain-targeting efficiency, enhance therapeutic efficacy, reduce systemic toxicity, and enable previously undruggable CNS targets. Finally, we expand the discussion to encompass current challenges impeding clinical translation, including safety concerns, manufacturing scalability, and regulatory hurdles, while highlighting emerging trends such as artificial intelligence-driven formulation design. This comprehensive analysis aims to deepen the understanding of nasal-to-brain transport mechanisms and inform the future development of effective nasal formulations for improved neurological therapeutics.
