FREQUENT MEDICAL QUESTIONS & ANSWERS
What is a venom of animal origin?
They are toxic substances produced by animals with the capacity to form toxic substances. The ability to secrete toxic substances constitutes a powerful offensive weapon, in which case the venom is generally secreted by glands in connection with the teeth (snakes), by bite (spider) or by sting (scorpion).
They are toxic substances produced by poisonous or venomous animals as an offensive weapon in a dangerous situation, such venom is generally secreted by glands that are in connection with the teeth in the case of a snake or spider bite or by the sting of a scorpion. These toxins have the ability to do local and systemic damage to the body.
What is antivenom?
It is a biological therapy indicated for the treatment of poisoning by bites or stings of venomous or poisonous animals; for example, snakes, scorpions and spiders whose function is to counteract the effects of a venom or at least prevent the undesirable damage of the toxic compounds.
How are antivenoms classified?
Although there are several classifications according to their composition, purity and neutralizing capacity, these classifications include monovalent and polyvalent antivenoms.
Monovalent is the one that recognizes and neutralizes the venom of a single species and is due to the fact that in its production process only the venom of a single species was used.
Polyvalent, is one that recognizes and neutralizes the venom of at least two different species and its neutralizing capacity depends on the number of venoms of different species that were used in its production.
How many types of antivenoms are there?
How many generations of antivenoms are there?
1st Generation Hyperimmune serum, biological product, low efficacy and safety.
2nd Generation Complete immunoglobulins (IgG). Serum, purified biological product of moderate efficacy and safety.
3rd and 4th Generation [Fab/ F(ab')2 antibody fragments]. Also called Fabotherapics, they are composed of the F(ab')2 fragment of the immunoglobulin, resulting from pepsin digestion of the antibodies can neutralize the venom and reduce hypersensitivity reactions of immediate type (anaphylaxis) and delayed type (serum sickness). Biotechnological product of high efficacy and safety.
How is an antivenom manufactured?
1. The venom of an animal (snake, scorpion or spider) is selected.
2. Horses are injected with this venom(s) so that their immune system responds by generating antibodies to all the components of the venom(s).
3. Plasma is extracted from the horses' blood.
4. The hyperimmune plasma is subjected to purification processes and strict quality controls.
5. The result is a sterile solution of antibodies or fragments of them and they are packaged in liquid or powder form (lyophilized).
What is the mechanism of action of antivenoms?
When the antivenom enters the organism it goes through 3 phases:
RECOGNITION: The F(ab')2 fragments specifically recognize the different toxic components of the venom.
PRECIPITATION: The F(ab')2 fragments bind to the toxic components of the venom to neutralize them, forming a complex (F(ab')2 fragment-toxic component).
ELIMINATION: The complex formed will facilitate the redistribution and elimination of the venom components from the organism.
What is the specificity in antivenoms?
It is the ability of antibodies or antibody fragments to recognize and bind to the components of venoms, which correlates with their potency and efficacy. The higher the specificity, the higher the efficacy.
What are the main characteristics and properties of INOSAN antivenoms?
Inosan antivenoms are produced using a state-of-the-art biotechnology manufacturing platform that meets the highest international quality standards.
Effectively covers all major medically important species in the Sub-Saharan Africa, North Africa and Middle East regions.
High Safety and Efficacy profile measured in extensive clinical studies.
No cold chain dependency due to lyophilized formulation.
How is the safety profile of INOSAN antivenoms determined?
By its level of highly purified F(ab')2 > 90%.
Because they have no preservatives.
Because they are pyrogen-free.
All of the above reduces the risk of allergic reactions and serum sickness.
How is the efficacy profile of INOSAN antivenoms determined?
It is performed in animal models (mice), where the effective dose is determined according to the biological activity also known as "Neutralization Potency".
How is the regional coverage of INOSAN's antivenoms (AV´s) guaranteed?
The design of the INOSAN AV´s is based on the WHO recommendation (Category 1) of the species of major medical importance for each region (Sub-Saharan Africa and North Africa and Middle East).
What criteria must a reliable antivenom meet?
Effective: To cover most common or widespread clinically important venomous snakes that result in high levels of morbidity, disability or mortality.
Safety/Tolerability: To allow use in remote rural health facilities.
Stability: Important in tropical regions to facilitate distribution.
Accessibility: Reliable source of supply and sustained availability.
