Overview of Tetig
Understanding Tetig
Tetig is a biological medicinal product containing the active substance anti-Tetanus immunoglobulin. It is a specialized preparation derived from human plasma that contains high levels of antibodies directed against the toxin produced by the bacterium Clostridium tetani.
Mechanism of Action
The primary function of Tetig is to provide immediate, passive immunity. Unlike a vaccine, which stimulates the body's own immune system to produce antibodies over time, this preparation introduces pre-formed antibodies directly into the system. These antibodies work by neutralizing the tetanus toxin, preventing it from binding to nerve endings and causing the muscular spasms associated with the disease.
Therapeutic Purpose
Tetig is primarily utilized in two clinical scenarios:
- Post-exposure Prophylaxis: It is used following an injury in individuals whose tetanus immunization history is incomplete, uncertain, or out of date. It serves as an immediate protective measure while the body responds to concurrent active immunization if administered.
- Therapeutic Management: It is used as a component in the clinical management of manifested tetanus infections to help neutralize circulating toxins.
Composition and Production
As a plasma-derived product, Tetig is manufactured through a rigorous fractionation process. The plasma used for production is sourced from selected donors who have high titers of specific antibodies against the tetanus toxin. The manufacturing process includes specific steps designed to ensure the purity of the protein fractions and to maintain the stability of the immunoglobulins.
