Angiotensin converting enzyme (ACE) inhibitors can cause dry cough. A single captopril dose did not alter bronchial tone in any group, suggesting ACE inhibitor cough is not asthma-related.

Area of Science:

  • Pharmacology
  • Pulmonology
  • Clinical Medicine

Context:

  • Dry cough is a known side effect of angiotensin converting enzyme (ACE) inhibitors.
  • Previous research has explored the long-term effects of ACE inhibitors on lung function.
  • The exact mechanism behind ACE inhibitor-induced cough remains unclear.

Purpose:

  • To investigate the immediate effect of a single oral dose of captopril on bronchial tone.
  • To assess if bronchial tone changes are linked to ACE inhibitor-induced cough.
  • To explore the potential asthmatic basis of cough associated with ACE inhibitors.

Summary:

  • A single 25 mg oral dose of captopril was administered to healthy controls, patients with obstructive pulmonary disease, and patients who previously experienced cough with ACE inhibitors.

  • Spirometric tests were conducted one hour post-ingestion.
  • No significant changes in spirometric parameters were observed in any participant group.

    • Impact:

    • Findings suggest that the cough associated with ACE inhibitors does not appear to stem from an asthmatic mechanism.
    • This study contributes to understanding the non-asthmatic pathogenesis of ACE inhibitor-induced cough.
    • Results complement existing data on the pulmonary effects of ACE inhibitors.
