Angiotensin-converting enzyme (“ACE”) inhibitors are common cardiac medications used in both human and veterinary medicine to treat heart disease and hypertension (high blood pressure). When accidentally ingested in poisonous amounts by pets, ACE inhibitors can result in hypotension (low blood pressure), lethargy, weakness, vomiting, and diarrhea. Pets with underlying medical problems (e.g., kidney failure, heart disease, etc.) can be more sensitive to the effects of these medications.
