Insights

Oral mexiletine effectively treated painful alcoholic neuropathy when standard analgesics failed. This therapy provided significant relief from tingling and aching sensations without major side effects.

Area of Science:

  • Neurology
  • Pharmacology

Background:

  • Alcoholic neuropathy is characterized by severe painful sensory disturbances in the extremities.
  • Conventional analgesic agents often fail to provide adequate pain relief for this condition.

Observation:

  • Five patients with painful alcoholic neuropathy experienced persistent sensory disturbances.
  • These patients did not respond to typical analgesic treatments.

Findings:

  • Oral mexiletine (MX) therapy demonstrated remarkable effectiveness in alleviating pain, particularly tingling and aching sensations.
  • The minimum effective dose of oral MX was found to be 300 mg daily.
  • The effective plasma concentration of MX was approximately 0.66 +/- 0.15 micrograms/ml.

Implications:

  • Oral mexiletine offers a reliable and effective treatment option for managing pain associated with alcoholic neuropathy.
  • This finding suggests a potential new therapeutic strategy for patients suffering from this debilitating condition.
