Why does administering antipyretics to a patient with heatstroke, particularly after exertion, sometimes prove ineffective at rapidly lowering their core body temperature?

💡 Explanation

In heatstroke, the hypothalamus's thermoregulatory set-point is overridden by the severity of the hyperthermia; therefore, antipyretics, which typically act by reducing the hypothalamic set-point, become ineffective because the primary issue isn't a regulated fever, rather than an overwhelmed system.
