Final answer:
To reverse epinephrine-induced vasospasm, the administration of nitrates like nitroglycerine is effective as it acts as a vasodilator by releasing nitric oxide.
Step-by-step explanation:
To reverse epinephrine-induced vasospasm, one of the effective methods is the administration of nitrates. Nitrates, such as nitroglycerine, work primarily by releasing nitric oxide, which acts as a potent vasodilator, helping to relax constricted blood vessels and thereby reversing the vasoconstriction. In the context of reversing epinephrine-induced vasospasm, simply removing the source of epinephrine is unlikely to be immediately effective, as the vasoconstrictive effects may persist. While warm compresses may help to a certain extent by promoting local vasodilation through heat, they are not the primary treatment in an acute setting. Calcium channel blockers also have a vasodilatory effect, but their primary indication is not for acute reversal of epinephrine-induced vasospasm.
