I don't know which one would be best for coughers, but you can have different reactions to different drugs. I tried Lotrel which is amlodipine and benazepril, a CCB and ACEI, and felt like I was going to cough up a lung, plus it did nothing for my bp. I curently take dilitizem (tiazac) and captopril, a CCB and ACEI and don't seem to be coughing, or at least not much. I'm also getting pretty good bp control.

So try a different ARB or even a different ACEI. I found it took a few weeks to get over the Lotrel cough, although supposedly if you stop the ACEI the cough stops immediately. If you aren't coughing too badly, you might even wait a bit and see if the cough goes away. Do you have pollen allergies? If so that might also be a factor in getting rid of the cough. I think it was for me.
