Amantadine for Traumatic Brain Injury-Supporting Evidence and Mode of Action

Area of Science:

• Neuroscience
• Pharmacology
• Clinical Medicine

Background:

• Traumatic brain injury (TBI) presents a significant global health challenge with complex pathological mechanisms impacting patient quality of life.
• Effective prevention and treatment strategies for TBI are crucial.

Purpose of the Study:

• To review the evidence supporting the use of amantadine in TBI management.
• To explore amantadine's mechanism of action in the context of TBI.
• To identify areas requiring further investigation regarding amantadine's efficacy in TBI.

Main Methods:

• Review of existing clinical evidence and guidelines concerning amantadine for TBI.
• Analysis of amantadine's multifaceted pharmacological actions relevant to TBI pathophysiology.
• Identification of knowledge gaps through critical evaluation of current literature.

Main Results:

• Amantadine exhibits potential neuroprotective and neuroactivating properties beneficial for TBI patients.
• Clinical guidelines recommend amantadine for TBI treatment.
• Amantadine's availability in infusion and oral forms offers flexible administration, particularly for unconscious patients.

Conclusions:

• Amantadine is a promising therapeutic agent for TBI, with established guideline support.
• Further well-controlled clinical trials are essential to confirm amantadine's utility in TBI, especially for long-term disorders of consciousness and combination therapies.
• Investigating amantadine's effects on disorders of consciousness from non-TBI etiologies is warranted.
