[Unsuspected danger of a medicinal preparation]

Inhaled foreign bodies are commonly reported in childhood but less so among adults. We report the case of a patient who inhaled a medicinal preparation containing meprobamate and quinine sulfate. The consequence of this was caustic damage to the airways.

A 64-year-old woman came to the emergency room because of dyspnea, oropharyngeal pain and sialorrhea. She reported that she had inhaled a capsule containing meprobamate and quinine sulfate the previous day. Flexible bronchoscopy showed evidence of caustic damage to the larynx and lower airways. The patient was treated by fasting, corticoids and intravenous broad-spectrum antibiotics. All the lesions recovered and she was discharged from the hospital 15 days after the event.

Inhalation of drugs mostly leads to airway obstruction. Risk of harm is influenced by neurological status, the motility of the digestive system and the properties of the drug. To the best of our knowledge, this is the first time that caustic airway disease has been described following inhalation of a medicinal preparation containing meprobamate and quinine. It highlights the need to be familiar with the chemical properties of medications when prescribing them to patients who are at risk of aspiration.
