ANTI-VENOM
-
Antivenin (or anti-venom or anti-venene) is a biological product used in the treatment of venomous bites or stings.
-
Anti-venom is created by milking venom from a relevant snake, spider, insect, or fish. The venom is then diluted and injected into a horse, sheep, rabbit, or goat. The subject animal will undergo an immune response to the venom, producing antibodies against the venom's active molecules which can then be harvested from the animal's blood and used to treat envenomation.
-
Internationally, anti-venoms must conform to the standards of pharmacopoeia and the World Health Organization also known as (WHO). The principle of anti-venom is based on that of vaccines, developed by Edward Jenner; however, instead of inducing immunity in the patient directly, it is induced in a host animal and the hyper immunized serum is transfused into the patient.
-
Anti-venoms can be classified into monovalent (when they are effective against a single species' venom) or polyvalent (when they are effective against a range of species, or several different species at the same time).
-
The first anti-venom for snakes (called an anti-ophidic serum) was developed by Albert Calmette, a French scientist of the Pasteur Institute working at its Indochine branch in 1895, against the Indian Cobra (Naja naja).
-
In 1901, Vital Brazil, working at the Instituto Butantanin São Paulo, Brazil, developed the first monovalent and polyvalent anti-venoms for Central and South American Crotalus and Bothrops genera, as well as for certain species of venomous spiders, scorpions, and frogs.
-
Anti-venoms for therapeutic use are often preserved as freeze-dried ampoules, but some are available only in liquid form and must be kept refrigerated.
-
They are not immediately inactivated by heat, however, so a minor gap in the cold chain is not disastrous.
-
The majority of anti-venoms (including all snake anti-venoms) are administered intravenously; however, stonefish and red back spider anti-venoms are given intramuscularly.
-
The intramuscular route has been questioned in some situations as not uniformly effective.
