Final answer:
Niacin-induced vasodilation reduces vascular resistance, leading to hypotension.
Explanation:
Vasodilation caused by niacin can lead to hypotension by decreasing vascular resistance within blood vessels, resulting in lower blood pressure. This effect is exacerbated in conditions like hypovolemia, where decreased blood volume further contributes to low blood pressure.
