Is diphtheria antitoxin still used?
The Food and Drug Administration has not licensed diphtheria antitoxin (DAT) for use in the United States. However, CDC is authorized to distribute DAT to treating clinicians as an investigational new drug (IND).
How does the diphtheria antitoxin work?
Diphtheria antitoxin is made from the blood plasma of horses that have been immunized against diphtheria toxin. It works by neutralizing the toxins produced by Corynebacterium diphtheriae. Diphtheria antitoxin was developed and came into medical use in the late 1800s.
How do horses cure diphtheria?
Antitoxin. New York HeraldThe first successful treatment for diphtheria was the administration of an antitoxin. An antitoxin serum was produced by inoculating horses with small amounts of the diphtheria toxin—enough to immunize without harming the animals. The horses would then be bled periodically.
What drugs are used for specific treatment of diphtheria?
Treatments include: Antibiotics. Antibiotics, such as penicillin or erythromycin, help kill bacteria in the body, clearing up infections. Antibiotics lessen the time that someone with diphtheria is contagious.
How effective was the diphtheria antitoxin?
Treatment of Diphtheria Antitoxin was first used to treat diphtheria in 1891 and has a clinical efficacy of 97%.
Why horse is selected for preparation of diphtheria antitoxin?
Initially joined by a few sheep, goats and dogs, the horses prevailed because they were larger and better antitoxin factories: when systematically injected with diphtheria toxin, their immune systems were prompted to develop neutralizing antibodies against the germ’s poison.
Why is an antitoxin required to treat cases of diphtheria?
Antitoxin is most effective in the early stages of the infection because it neutralizes free diphtheria. A 14-day regimen of erythromycin or intramuscular procaine penicillin G also is recommended to treat active cases.
Why is anti diphtheria toxin administered?
Patients with diphtheria are treated with equine diphtheria antitoxin, which neutralizes unbound diphtheria toxin. This treatment can result in serum sickness, an immune complex disease, so a better treatment for diphtheria patients would be desirable.
What does horse serum do?

What is the mainstay of treatment for diphtheria?
Diphtheria antitoxin is considered the mainstay of treatment for diphtheria; it will not neutralize diphtheria toxin that is already fixed to tissues, it will only neutralize circulating (unbound) diphtheria toxin and prevent the progression of disease.
