Chronic cough due to angiotensin-converting enzyme inhibitors.
The ACE-inhibiting drugs enalapril and captopril may result in a chronic and sometimes severe cough for which no pathologic cause can be found. Drug-induced cough should therefore be considered in any symptomatic patient taking these medications. In such cases, prompt withdrawal of the drug and substitution of a non-ACE inhibitor is curative and conserves the time and resources of the patient and the physician by avoiding unnecessary diagnostic and therapeutic measures.
