Role of Perindopril in Mitigating Doxorubicin's Vascular Toxicity in a Rat Model.

ABSTRACT: Doxorubicin (DOX), a widely used anthracycline in cancer therapy, is associated with significant cardiovascular toxicity. While its cardiotoxic effects are well documented, the mechanisms and prevention of DOX-induced vascular toxicity remain insufficiently explored. Angiotensin-converting enzyme inhibitors (ACEIs), such as perindopril (PER), are commonly used in cardiovascular disease management and may offer vascular protection during chemotherapy. Female ovariectomized Wistar rats were treated with i.v. DOX and/or p.o. PER over five weeks. Cardiac and vascular function were assessed using high-frequency ultrasound and ECG. Vascular reactivity was evaluated in isolated aortal rings using phenylephrine (PE), acetylcholine (ACh), L-N-Nitro arginine methyl ester hydrochloride (L-NAME), and
