A team of scientists from Australia, Canada, Costa Rica, and the UK has discovered that a commonly prescribed blood-thinning drug, Heparin, can be repurposed as an affordable antidote to cobra venom. Cobra bites, which are prevalent in parts of Africa and India, cause about 138,000 deaths annually and leave over 400,000 individuals suffering from necrosis. Unlike many existing antivenoms that are specific to single snake species and fail to prevent necrosis, Heparin neutralizes the necrosis-causing toxins in spitting cobra venom.
After successful tests on mice, the researchers plan to move on to human trials. The study highlighted the potential impact of this discovery as it could significantly reduce the injuries and fatalities caused by cobra bites. The study also emphasized the limitations of current antivenoms, which are often ineffective against severe local envenoming that can…
