Excreted by kidney; may require dosage reduction in patients with renal insufficiency. Hypotension has been observed with initiation of AGE inhibitors, especially in patients with high plasma renin activity or hypovolemia (e.g., in those receiving diuretic therapy).	Cough, angioedema (rare, hyperkalemia (especially when given to patients with renal failure and/or with a potassium-sparing diuretic or a nonsteroidal anti-inflammatory drug), dysgeusia, neutropenia (rare), proteinuria (rare at recommended doses), rash.
