Bradykinin is converted into inactive metabolites by
#Angiotensin_converting_enzyme
therfore ACE-Is :
#Angiotensin_converting_enzyme_inhibitors
(Captopril, Ramipril, Enalapril , Moxeipril...etc)
lead to accumulation of bradykinin ----> Irritation of cough receptors----> Dry Cough
------------------------------------------------------------------------
N.B :
In case of intolerance to ACE-Is due to dry cough, the good alternative vasodilators are
#Angiotensin_receptors_blockers(ARBs) (Candesartan, Olmesartan, Valsartan....etc)
