Bronchial hyperreactivity induced by angiotensin converting enzyme inhibitor
Singapore Medical Journal
|June 1, 1991
Summary
Angiotensin converting enzyme (ACE) inhibitors can cause cough and bronchial hyperreactivity, even in non-asthmatic patients. This case highlights a potential link between ACE inhibitors, cough, and airway responsiveness.
Area of Science:
- Pharmacology
- Respiratory Medicine
- Clinical Case Studies
Background:
- Angiotensin converting enzyme (ACE) inhibitors are widely prescribed for cardiovascular conditions.
- A persistent dry cough is a known side effect of ACE inhibitors, affecting up to 20% of patients.
- The mechanism underlying ACE inhibitor-induced cough and its impact on bronchial reactivity remain incompletely understood.
Observation:
- This report details a case of a non-asthmatic individual who developed a significant cough after initiating lisinopril therapy.
- The patient also exhibited demonstrable bronchial hyperreactivity, a condition typically associated with asthma.
Findings:
- The patient's cough and bronchial hyperreactivity were directly attributed to lisinopril, an ACE inhibitor.
- This case suggests that ACE inhibitors may induce bronchial hyperreactivity independently of pre-existing asthma.
- The findings challenge the notion that ACE inhibitors only affect those with existing airway conditions.
Implications:
- This case underscores the importance of considering ACE inhibitor-induced cough and hyperreactivity in patients presenting with these symptoms, even in the absence of asthma.
- Further research is warranted to elucidate the precise mechanisms by which ACE inhibitors affect airway function.
- Clinicians should be aware of this potential adverse effect when prescribing ACE inhibitors.
