Abstract
Nicotinamide riboside (NR) serves as a precursor to NAD+. Numerous studies in the literature report on the oral administration of NR, demonstrating its beneficial effects on the progression of diseases such as cardiovascular, neurodegenerative, renal, hepatic, and others. Previously, a hypothesis was proposed by the authors suggesting a protective effect of intravenous NR administration against doxorubicin-induced myocardial damage. However, under this mode of administration, special attention must be given to the biocompatibility of NR when used at therapeutically effective doses. Thus, the aim of this study was to assess the biocompatibility of various NR doses with repeated intravenous administration in Wistar rats. The study employed doses of 150, 300, 450, and 600 mg/kg of NR (cumulative doses of 900, 1800, 2700, and 3600 mg/kg, respectively). During the study, the biocompatibility of NR was demonstrated at doses of 150, 300, and 450 mg/kg with repeated intravenous administration in rats. Even at the highest dose of 450 mg/kg, repeated intravenous administration showed no adverse effects on the parasympathetic ganglia of the autonomic nervous system in the heart. However, increasing the dose of NR led to several adverse side effects, including animal mortality, reduced tolerance to physical exertion, impaired cardiovascular function, and morphological and functional changes in the myocardium, liver, and kidneys.
