Horses were fasted overnight prior to receiving one of 4 ACE inhibitors intragastrically, administered at one of 2 dosages, using a randomized Latin square design (benazepril: 0.5 and 0.25 mg\/kg; ramipril: 0.3 and 0.1 mg\/kg; quinapril: 0.25 and 0.125 mg\/kg; perindopril: 0.1 and 0.05 mg\/kg).

There was a significant decrease in indirect blood pressure (BP) over time after administration of each drug, but differences in BP were not significantly different between drugs. Pharmacodynamic variables measured after administration of benazepril to horses with free access to hay were not significantly different from those obtained after fasting. Administration of benazepril orally once daily for 7 days did not result in a cumulative effect on ACE inhibition.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
