How does Botulinum toxin work?

Botox (Botulinum toxin ) is used medically to treat certain muscular conditions, and cosmetically to remove wrinkles by temporarily paralyzing muscles. It is made from a neurotoxin called botulinum toxin that is produced by the bacterium Clostridium botulinum.
Although Botox is a powerful poison, when used correctly, it has a number of applications.

In this article, we will explain how it works, what Botox is used for, and talk about any side effects and dangers.

Fast facts on Botox:
Botox is the most popular non-surgical cosmetic treatment, with more than 6 million Botox treatments administered each year.
Botox is a neurotoxin derived from Clostridium botulinum, an organism found in the natural environment where it is largely inactive and non-toxic.
Botulinum toxin is used to reduce fine lines and wrinkles by paralyzing the underlying muscles.
People also use Botox to treat excessive sweating, migraines, muscular disorders, and some bladder and bowel disorders.
Botulism, an illness caused by botulinum toxin, can cause respiratory failure and prove deadly.
Just 1 gram of botulinum toxin could kill over 1 million people. Two kilograms could kill the entire human population of Earth.

What is Botox?

Botox injections have a range of medical uses.
Clostridium botulinum, the bacterium from which Botox is derived, is found in many natural settings, including soil, lakes, and forests.

The bacterium can also be found in the intestinal tracts of mammals and fish and in the gills and organs of crabs and other shellfish. Such naturally occurring instances of Clostridium botulinum bacteria and spores are generally harmless. Problems only arise when the spores transform into vegetative cells and the cell population increases. At a certain point, the bacteria begin producing botulinum toxin, the deadly neurotoxin responsible for botulism.

Neurotoxins target the nervous system, disrupting the signaling processes that allow neurons to communicate effectively.

How does Botox work?
Botulinum toxin is one of the most poisonous substances known to man. Scientists have estimated that a single gram could kill as many as 1 million people and a couple of kilograms could kill every human on earth. In high concentrations, botulinum toxin can result in botulism, a severe, life-threatening illness. Botulism, left untreated, may result in respiratory failure and death. Despite botulinum toxin being so toxic, Botox is in huge demand.

Despite this, botulinum toxin has proven to be a successful and valuable therapeutic protein.

Botulinum toxin can be injected into humans in extremely small concentrations and works by preventing signals from the nerve cells reaching muscles, therefore paralyzing them.

In order for muscles to contract, nerves release a chemical messenger, acetylcholine (a neurotransmitter), at the junction where the nerve endings meet muscle cells. Acetylcholine attaches to receptors on the muscle cells and causes the muscle cells to contract or shorten.

Injected botulinum toxin prevents the release of acetylcholine, preventing contraction of the muscle cells. Botulinum toxin causes a reduction in abnormal muscle contraction, allowing the muscles to become less stiff.

Medical and cosmetic uses of Botox

Botox is most commonly used for cosmetic purposes to improve the appearance of fine lines and wrinkles.
Botulinum toxin is predominantly used as a treatment to reduce the appearance of facial wrinkles and fine lines.

Beyond aesthetic applications, Botox is used to treat a variety of medical conditions, including eye squints, migraines, excess sweating, and leaky bladders.

Botulinum toxin is currently used to treat over 20 different medical conditions, with more applications under investigation.

Botox is currently approved for the following therapeutic applications:

  • Blepharospasm (spasm of the eyelids).
  • Idiopathic rotational cervical dystonia (severe neck and shoulder muscle spasms).
  • Chronic migraine.
  • Severe primary axillary hyperhidrosis (excessive sweating).
  • Strabismus (crossed eyes).
  • Post-stroke upper limb spasticity.
  • Detrusor (bladder wall muscle) overactivity – causing urinary incontinence.
  • Overactive bladder.
  • Hemifacial spasm.
  • Glabellar lines (frown lines between the eyebrows).
  • Canthal lines (crow’s feet).

Botulinum toxin is also used off-label (not approved) for:

Achalasia (an issue with the throat that makes swallowing difficult).
Anal fissure and anismus (dysfunction of the anal sphincter).
Sialorrhea (producing too much saliva).
Allergic rhinitis (hay fever).
Sphincter of oddi (hepatopancreatic) dysfunction (causes abdominal pain).
Cerebral Palsy.
Oromandibular dystonia (forceful contraction of the jaw, face, and/or tongue).
Laryngeal dystonia (forceful contraction of the vocal cords).
