Answer

Adrenergic blocking agents and vasodilators

Adrenergic blocking agents and vasodilators are used to counteract the scorpion-induced adrenergic cardiovascular effect.

Labetalol (Normodyne, Trandate)

Labetalol blocks beta1-adrenergic, alpha-adrenergic, and beta2-adrenergic receptor sites, decreasing blood pressure.

Prazosin (Minipress)

Prazosin counteracts the scorpion-induced adrenergic cardiovascular effects. It may improve pulmonary edema through vasodilatory effects.

Hydralazine (Apresoline)

Hydralazine decreases systemic resistance through direct vasodilation of arterioles.
