Drugs from which category reduce preload and afterload?

Explanation:
Vasodilators. Dilating veins reduces venous return, lowering ventricular filling pressures and preload. Dilating arteries lowers systemic vascular resistance, reducing afterload. Some vasodilators mainly affect one side (venous or arterial), while others affect both, but as a group they can decrease both preload and afterload, which is why they’re the category that can impact both.
