So, we will look at captopril as an example to understand ACE inhibitors mechanism of action. In pathologic states, such as heart or liver failure, the vasoconstriction and volume retention produced by RAAS results in total volume overload and volume redistribution to extravascular tissues, which is why we often see pulmonary edema, ascites, and lower extremity edema in these types of conditions. That means it has the opposite effect as that of angiotensin 2. [37][38]Experimental studies have shown that using non-steroidal anti-inflammatory agents (NSAIDs) and intermediate-dose aspirin (500 mg) can help with ACE inhibitors induced cough. Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen (Advil, Motrin IB, others) and naproxen sodium (Aleve), decrease the effectiveness of ACE inhibitors.
