Ambroxol-induced focal epileptic seizure

Area of Science:

• Pharmacology
• Neurology
• Clinical Medicine

Background:

• Epilepsy management involves careful consideration of potential drug-induced seizures.
• Various pharmacological agents and excipients can interact with antiepileptic drugs or directly affect neuronal excitability.
• Comorbidity treatment in epileptic patients requires vigilance for adverse effects, including seizure provocation.

Observation:

• A patient with drug-resistant epilepsy presented with consistently reproducible focal seizures.
• These seizures were repeatedly observed following the administration of a specific cough syrup.
• The cough syrup's active ingredient was identified as ambroxol.

Findings:

• This report details the first electroencephalogram-documented instance of focal epileptic seizures induced by ambroxol.
• The findings suggest a direct link between ambroxol exposure and seizure activity in this susceptible patient.
• The case highlights the potential for commonly used medications, like cough syrups, to precipitate seizures.

Implications:

• Clinicians should be aware of the potential for ambroxol-containing cough syrups to induce seizures in epileptic individuals.
• This case underscores the importance of thorough medication review in patients with difficult-to-control epilepsy.
• Further research into the proconvulsant potential of ambroxol and other cough syrup components is warranted.
