Area of Science:

  • Pharmacology and Toxicology
  • Immunotherapy
  • Biotechnology

Background:

  • Antivenom therapy, discovered a century ago, still relies on empirical use despite manufacturing advancements.
  • Understanding of envenoming pharmacokinetics has improved, offering new insights into immunotherapy.
  • Purification of antivenom using immunoglobulin fragments enhances tolerance and efficacy.

Purpose of the Study:

  • To review the current state of antivenom immunotherapy.
  • To discuss the advantages and disadvantages of different immunoglobulin fragments (F(ab')2 and F(ab)).
  • To highlight the importance of administration routes and adherence to protocols.

Main Methods:

  • Review of recent pharmacokinetic studies of envenoming.
  • Analysis of immunoglobulin fragment purification techniques.
  • Discussion of clinical efficacy and safety data related to antivenom administration.

Main Results:

  • Immunoglobulin fragments (F(ab')2 and F(ab)) offer improved antivenom tolerance and efficiency.
  • Intravenous administration of antivenom is demonstrably superior.
  • The optimal timing for antivenom administration remains to be fully elucidated.

Conclusions:

  • Modern technology can further refine antivenom production and immunotherapy protocols.
  • Rigid adherence to therapeutic guidelines is essential for maximizing immunotherapy benefits.
  • The potential of vaccination in antivenom treatment warrants further exploration.
