Implication

Animal study demonstrates that ranolazine mitigates memory impairment and neurodegeneration in scopolamine-treated rats, suggesting therapeutic potential for Alzheimer's disease.

Key Points

To examine the neuroprotective effects of ranolazine on behavioral impairment, oxidative stress, inflammation, and neuronal damage in a scopolamine-induced rat model of dementia.
Thirty-two male albino rats were allocated into four experimental groups: control, ranolazine alone, scopolamine alone, and ranolazine plus scopolamine.
Cognitive and spatial memory performance was assessed using the Morris water maze, followed by biochemical, histological, and immunohistochemical evaluations of hippocampal tissue.
Ranolazine pre-treatment significantly decreased escape latency in the Morris water maze and substantially reduced hippocampal acetylcholinesterase activity compared to scopolamine alone.
Ranolazine markedly enhanced antioxidant enzyme activity, upregulated brain-derived neurotrophic factor (BDNF) expression, and reduced inflammatory cytokines IL-1β and IL-6.
Pre-treatment substantially suppressed scopolamine-induced increases in Tau protein, GFAP immunoreactivity, and Caspase-3 expression while preserving normal pyramidal neuron morphology.
