This damage leads to the formation of fibrotic blood vessels and impaired energy metabolism, both of which hinder recovery. Felodipine, a clinically approved antihypertensive drug, acts as a selective calcium antagonist, primarily inhibiting extracellular calcium influx in arteriolar smooth muscle and selectively dilating arterioles. Additionally, felodipine has been demonstrated to induce autophagy. Considering these properties collectively, we hypothesised that felodipine could modulate the microenvironment of the injured spinal cord. In this study, we employed immunofluorescence and Western blot analyses to evaluate the effects of felodipine on microenvironment repair and neuroprotection, both in\u00a0vitro and in\u00a0vivo. Particular attention was given to its regulatory role in AMPK\u2010mTOR pathway\u2010mediated macrolipophagy. Our results demonstrated that felodipine effectively improved the injured spinal cord microenvironment by activating macrolipophagy, facilitating the clearance of myelin debris. Furthermore, felodipine promoted the restoration of endothelial cell tight junctions, thereby enhancing the integrity of the blood\u2013spinal cord barrier. This attenuation of barrier disruption after SCI contributed to improved neuronal survival. These findings expanded the clinical application prospect of felodipine and presented new therapeutic avenues for treating SCI.<\/jats:p>","DOI":"10.1111\/jcmm.70543","type":"journal-article","created":{"date-parts":[[2025,4,22]],"date-time":"2025-04-22T04:39:40Z","timestamp":1745296780000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Felodipine
