Botulinum toxin is a natural purified protein and one of the strongest biological poisons--neurotoxin. It is produced by the bacterium Clostridium botulinum. Its medical usage started in USA in 1981 and in Europe in 1992. There are seven different immune types of the toxin: A, B, C1, D, E, F and G. Toxin types A and B are used to decrease muscular spasticity. Botulinum toxin prevents the format...

Botulinum toxin blocks transmitter release by proceeding through a series of four steps: binding to cell surface receptors, penetration of the cell membrane by receptor-mediated endocytosis, penetration of the endosome membrane by pH-induced translocation, and intracellular proteolysis of substrates that govern exocytosis. Each of these steps is essential for toxin action on intact cells. There...

We have read the case report of Al-Ahmad and Al-Qudah1 regarding the use of botulinum toxin type A in the treatment of masseter hypertrophy, and we agree with the authors when they reported that botulinum toxin type A is an option for patients who declined surgical treatment. However, we would like to make some considerations concerning this type of treatment that can contribute to the authors’...

Botulinum A is currently drug first choice migraine. Numerous studies confirm effectiveness safety in clinical practice.

Botulinum neurotoxins, causative agents of botulism in humans, are produced by Clostridium botulinum, an anaerobic spore-former Gram positive bacillus. Botulinum neurotoxin poses a major bioweapon threat because of its extreme potency and lethality; its ease of production, transport, and misuse; and the need for prolonged intensive care among affected persons. A single gram of crystalline toxin...

Since its development for clinical use in 1980s botulinum toxin, the most potent biological toxin known to man has become a useful drug in various field of medicine. It was initially used to treat neurological disorders characterized by excessive muscle contractions. Since many patients report alleviation of pain before the muscle relaxing effect of botulinum toxin type-A has started, a direct ...

Background: Spasticity is one of the problems after a stroke. Due to this increase in muscle tone, patients are confronted with problems in motor control and difficulties in activities of daily living and complications such as shortness and contracture. The aim of this study was to examine the effects of the simultaneous use of both splint and botulinum toxin-A (BTX-A) injection on spasticity, ...

Botulinum toxin A injection is performed most frequently for facial rejuvenation all over the world. Some bizarre and severe side effects have been reported after botulinum toxin A injection. Herein, we present a case of vasculitis with panniculitis after a patient underwent a cosmetic procedure that included injection of purported botulinum toxin A.

Lack of Interchangeability Between Botulinum Toxin Products The potency Units of BOTOX® are specific to the preparation and assay method utilized. They are not interchangeable with other preparations of botulinum toxin products and, therefore, Units of biological activity of BOTOX® cannot be compared to nor converted into Units of any other botulinum toxin products assessed with any other speci...

The most poisonous substance known to man, botulinum toxin has successfully established itself as a therapeutic agent over the years. Initially used to treat strabismus, botulinum toxin is now an accepted treatment in a wide spectrum of disorders and has over a 100 potential medical applications. The somewhat loosely-applied term 'wonder drug' could not be better employed to describe the remedi...
