Answer 10

10.  Choice B is the correct answer.  Elevated bradykinnin levels are responsible for the dry cough in patients that take ACE inhibitors.  It should be thought of as a class effect. Switching the patient to an Angiotensin Receptor Blocker would help this.  There is no elevated bradykinnin levels with that class.  Prostaglandin levels are increased with ACE inhibitors and ARB’s but do not cause the dry cough.  Elevated cyclooxygenase levels and catecholamine levels have nothing to do with the dry cough or ACE inhibitors.
