Can Amlodipine Cause Coughing?
Introduction to Amlodipine and Cough
Amlodipine is a widely used calcium channel blocker prescribed for the treatment of hypertension and angina. While it is generally well-tolerated, there have been inquiries about whether it can cause coughing, a common side effect associated with some antihypertensive medications.
Amlodipine and ACE Inhibitor-Induced Cough
Research indicates that amlodipine may actually reduce cough induced by angiotensin-converting enzyme (ACE) inhibitors. A study comparing the effects of amlodipine, nifedipine, and indomethacin on ACE inhibitor-induced cough found that amlodipine reduced the incidence of cough, although not as effectively as indomethacin1. This suggests that amlodipine might have a mitigating effect on cough rather than causing it.
Incidence of Cough in Amlodipine Users
In a clinical trial comparing the incidence of cough among patients treated with different antihypertensive agents, only two out of sixty patients reported cough during treatment with amlodipine. This was significantly lower compared to the high incidence of cough observed in patients treated with ACE inhibitors3. Another study evaluating the tolerability of amlodipine in a large patient population reported that cough was an ill-defined and rare adverse event, occurring in less than 1% of patients7.
Case Studies and Clinical Observations
Several case studies and clinical observations further support the low incidence of cough associated with amlodipine. For instance, a 56-year-old patient on amlodipine for eight years did not report cough as a symptom, despite having other health issues2. Similarly, a 70-year-old woman with a chronic cough was evaluated, and her cough was not attributed to amlodipine, which she was taking for hypertension6.
Comparative Studies with Other Antihypertensives
Comparative studies have shown that amlodipine has a lower incidence of cough compared to other antihypertensive medications like ACE inhibitors. In a study evaluating the antihypertensive effect and tolerability of losartan, amlodipine, and lisinopril, patients on lisinopril had a high incidence of coughing (31.7%), whereas those on amlodipine did not report significant coughing issues4.
Conclusion
Based on the available research and clinical data, amlodipine is not commonly associated with causing cough. In fact, it may help reduce cough in patients who experience this side effect from ACE inhibitors. While rare cases of cough have been reported, they are not prevalent enough to consider coughing a significant side effect of amlodipine. Therefore, amlodipine remains a well-tolerated option for managing hypertension and angina with a low risk of inducing cough.

Cough and fever in a 56-year-old male patient were caused by a rare autoimmune condition, causing a protein to accumulate in the lungs and cause a dry cough and fever.

Imidapril has no selectivity in inhibiting angiotensin I and bradykinin degradation in rats, and is not different from other ACE inhibitors in inducing cough in patients with hypertension.
