Nicotinamide riboside (NR) is neuroprotective; however, its low permeability through the blood‒brain barrier restricts its therapeutic efficacy in central nervous system diseases. Compared with oral NR administration, liposome-based NR loading is hypothesized to improve its pharmacological properties during cerebral ischemia, especially when administered intravenously.
NR chloride (NRC) was encapsulated in an optimized liposome composition and administered by bolus intravenous injection. This was followed by examination of its pharmacokinetics, organ distribution, and effects on cerebral ischemia in mice.
Compared with conventional NRC solution, the liposome form led to a 2.76-fold higher Cmax and a 5.32-fold higher AUC0–24h in plasma after a bolus injection of 40 mg/kg. In healthy mouse brain, it caused a significant elevation of Cmax (2.93-fold) and AUC0.25–24h (2.68-fold). In cerebral ischemia model mice, NRC liposomes increased the drug concentration at 1 and 6 h post-ischemia, increased tissue NAD+ and ATP levels, reduced infarct volume (by a further decrease of 35.4%), ensured neuronal survival, attenuated glial activation, and significantly improved behavioral recovery compared with conventional NRC treatment.
Liposome loading enhances the brain distribution and therapeutic effects of NRC, which strengthens its possibility for clinical translation and neurorestoration in stroke.
