Innovative approach in Parkinson's targeting via berberine-loaded mucoadhesive surface-modified liposomes: a multi-faceted study.
Article in BMC pharmacology & toxicology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
backgroundTremors and rigid muscles are symptoms of Parkinson's disease (PD), which affects about 1% of the global population. PURPOSE: To investigate the integrated therapeutic benefits of the phytopharmaceutical berberine and mucoadhesive nanoliposomes, administered via the nose-to-brain route, to enhance bioavailability, facilitate blood-brain barrier penetration, and augment efficacy against neurodegenerative progression in Parkinson's disease (PD). STUDY
designThis study aimed to develop and characterize chitosan-decorated liposomes (chitosomes) loaded with berberine (BER) for targeted brain delivery via the intranasal route.
methodsIn vitro characterization of BER loaded chitosomes was conducted including measurement of particle size, zeta potential, EE % and in vitro drug release. The optimized formulation was intranasally administered in rats with rotenone-induced PD animal model, motor function and coordination were investigated besides testing the levels of different biomarkers and histopathological examination.
resultsThe prepared chitosomes had a particle size of 312 nm, zeta potential of 34 mV, and high encapsulation efficiency (89.3%) and sustained drug release. In vivo assessments conducted in a rotenone-induced PD animal model revealed notable improvements in motor function and coordination. Biochemical evaluations showed that BER chitosomes reduced α-synuclein by 49% and raised dopamine levels by 55% as compared to the model group. Additionally, BER chitosomes significantly decreased oxidative stress markers by a 67% decrease in NF-κB levels and a one-fold increase in Nrf2. Histological examination showed a noticeable reduction in neuronal degeneration and Lewy body formation.
conclusionOur findings imply that BER chitosomes are a viable intranasal delivery tool for the efficient treatment of PD due to their enhanced bioavailability. and greater nasal mucosa penetration.
