Potential Pharmacologic Treatments in Spinal Cord Injury: A Narrative Review

Area of Science:

• Neuroscience
• Pharmacology
• Regenerative Medicine

Background:

• Spinal cord injury (SCI) is a devastating condition with limited treatment options.
• Pharmacologic strategies are being investigated to improve neurological outcomes post-SCI.
• Past therapies like methylprednisolone have shown inconsistent efficacy.

Purpose of the Study:

• To review historical and current pharmacologic therapies for SCI.
• To highlight emerging drug candidates and biologics.
• To discuss challenges and future directions in SCI pharmacotherapy.

Main Methods:

• Narrative review of existing literature on SCI pharmacologic treatments.
• Analysis of preclinical and clinical trial data.
• Discussion of pathophysiological targets and therapeutic strategies.

Main Results:

• Corticosteroids have shown limited consistent efficacy.
• Emerging candidates include riluzole, minocycline, G-CSF, and Rho/ROCK pathway inhibitors.
• Clinical trials face challenges like patient heterogeneity and narrow therapeutic windows.

Conclusions:

• No single drug has achieved guideline endorsement for SCI.
• Future treatments likely involve tailored, multimodal regimens.
• Integration of pharmacotherapy with surgery, rehabilitation, and bioengineering is crucial for advancing SCI care.
