When is snake venom used in medicine?
Neurotoxins with either pre- or postsynaptic effects have been used to study neurogenic synapses and neuromuscular plaques and the development of analgesics, muscle relaxants and drugs for neurodegenerative diseases.
What is snake venom used for in medicine?
While deadly to prey, the anticoagulant properties of this venom is key to its potential medical uses. These toxins have applications in treating strokes, heart attacks and pulmonary embolisms, all of which can stem from blood clots.
