Botulin toxin is a neurotoxic protein produced by the bacterium Clostridium botulinum. It is the most poisonous naturally occurring substance in the world. A single drop is capable of killing 50,000 people. Though it is highly toxic, it is used in minute doses both to treat painful muscle spasms, and as a cosmetic treatment in some parts of the world. It is sold commercially under the brand names Botox and Dysport for this purpose. The terms Botox and Dysport are trade names and are not used generically to describe the neurotoxins produced by Clostridia species.

History

---

The German physician and singer Justinus Kerner called botulinum toxin "sausage poison", as this bacterium often causes poisoning by growing in badly handled prepared meat products. He first conceived a possible therapeutic use of botulinum toxin. In 1870, Muller (another German physician) coined the name botulism, from Latin botulus = "sausage". In 1895, Emile Van Ermengem first isolated the bacterium Clostridium botulinum. In 1944, Edward Schantz cultured Clostridium botulinum and isolated the toxin, and, in 1949, Burgen's group discovered that botulinum toxin blocks neuromuscular transmission. Throughout the 1950s, the toxin was used experimentally in the medical cosmetic treatment of politicians. Then actor-turned-politician Ronald Reagan is rumoured to be one of the earliest patients of this microexpression-concealing procedure.

By 1973, Alan B Scott, MD, of Smith-Kettlewell Institute used botulinum toxin type A (BTX-A) in monkey experiments, and, in 1980, he officially used BTX-A for the first time in humans to treat strabismus. In December 1989, BTX-A (BOTOX) was approved by the US Food and Drug Administration (FDA) for the treatment of strabismus, blepharospasm, and hemifacial spasm in patients over 12 years old. The cosmetic effect of BTX-A was initially described by the Carruthers, a dermatologist/ophthalmologist husband and wife team although the effect had been observed by a number of independent groups. On April 15, 2002, the FDA announced the approval of botulinum toxin type A (BOTOX Cosmetic) to temporarily improve the appearance of moderate-to-severe frown lines between the eyebrows (glabellar lines). BTX-A has also been approved for the treatment of excessive underarm sweating. The acceptance of BTX-A use for the treatment of spasticity and muscle pain disorders is growing, with approvals pending in many European countries and studies on headaches (including migraine), prostatic symptoms, asthma, obesity and many other possible indications are ongoing.
