Composition of Snake Venom
Secreted by venomous glands (parotid glands) beneath the eye.
Components include:

Enzymes: Phospholipases, proteases, metalloproteinases.
Inorganic Cations: Sodium, potassium, calcium, magnesium.
Physiological Effects:
Hemolysis via phosphodiesterase A2.
Venom Categories:
Hemotoxic: Affects cardiovascular system.
Neurotoxic: Affects nervous system.
Cytotoxic: Damages cellular processes.
Anti-Venom
History: First anti-venom developed by Albert Calmette.
Types:
Monovalent: Against specific venom.
Polyvalent: Against multiple species venoms.
Extraction Process:
Venom milking involves holding the snake and squeezing to collect venom safely.
Rigorous sterilization to avoid contamination.
Anti-Venom Stability and Storage
Liquid preparations: Shelf life ~3 years, stored at 2-8°C.
Freeze-dried versions: ~5 years at room temperature.
Therapeutic Potential of Snake Venom
Used in treating conditions like cancer and hypertension.
Research Insights:
Anti-coagulation properties beneficial in thrombotic conditions (e.g., Aggrastat from saw-scaled viper venom).
Cobra venom has been researched for its anti-arrhythmic properties.
Examples of Venom-Derived Treatments:
Anti-Cancer Potential:
Cytotoxic effects on cancer cells documented.
Components like L-amino acid oxidases induce apoptosis in tumor cells.
Other Therapeutics:
Anti-hypertensive drugs (e.g., Captopril from Bothrops jararaca).
Side Effects of Anti-Venom
Anaphylactic reactions include skin reddening, breathing difficulties, and joint inflammation.
Case Study: Snake Venom Addiction
Report of a 33-year-old male using snake venom as an opioid substitute.
Positive effects noted: reduced cravings and prolonged high, with severe risks associated with snakebites.
Research Directions
Continued studies focus on the potential applications of snake venom in pharmacology, particularly for cancer treatment.
Nanoparticles combined with venom elements showing promising targeting mechanisms for tumors.
Conclusion
Snake venoms present a complex mix of proteins, enzymes, and metabolites with crucial pharmacological implications.
Ongoing research is likely to reveal additional therapeutic agents for a range of diseases, especially in oncology.
