Which antidote is effective against poisoning from Indian Scorpio?

Prazosin is an effective antidote against poisoning from Indian Scorpio, specifically for the bites of the Indian red scorpion (Hottentotta tamulus). The venom of this scorpion contains a potent neurotoxin that can lead to significant cardiovascular and autonomic system effects, most notably acute pulmonary edema, severe hypertension, and tachycardia.

Prazosin is an alpha-1 adrenergic antagonist that helps to counteract some of the cardiovascular effects induced by the venom. It causes vasodilation, which can reduce the elevated blood pressure that often results from scorpion stings. Thus, the administration of prazosin can alleviate some of the systemic symptoms and provide critical management for the complications arising from such snake envenomations.

In contrast, while atropine is an anticholinergic drug used to treat certain types of poisoning, it doesn’t address the specific effects of the Indian scorpion venom. Calcium gluconate is used to treat calcium channel blocker toxicity and does not have a role in managing scorpion bites. Activated charcoal can be helpful in general cases of poisoning when administered soon after the ingestion of a toxin, but in the case of scorpion envenomation, this approach is not relevant, as the
