Botox: How Does Botox Work?


MNT Knowledge Center

Botox is a drug made from a neurotoxin produced by the bacterium Clostridium botulinum called botulinum toxin. It is used medically to treat certain muscular conditions and cosmetically remove wrinkles by temporarily paralyzing muscles.

Botulinum toxin is sold commercially under the names:

  • Botox, Vistabel, Botox cosmetic (OnabotulinumtoxinA or botulinum toxin type A)
  • Dysport (AbobotulinumtoxinA or botulinum toxin type A)
  • Bocouture, Xeomin (IncobotulinumtoxinA or botulinum toxin type A)
  • Myobloc (RimabotulinumtoxinB or botulinum toxin type B).

Fast facts on Botox

Here are some key points about Botox. More detail and supporting information is in the main article.

  • Botox is the most popular cosmetic surgery 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 paralysing the underlying muscles.
  • People also use Botox to treat excessive sweating, migraines, muscular disorders, and some bladder and bowel disorders.
  • Botulism, an infection with botulinum toxin, can cause respiratory failure and prove deadly.
  • Just one gram of botulinum toxin could kill over a million people. Two kilograms could kill the entire human population of Earth.

The origin of botox

Clostridium botulinum, the organism that Botox treatment comes, can be found in inactive form within the natural atmosphere, including within the forest and cultivated soils, as well as in the sediment of ponds, streams, seaside and untreated waters.

The bacteria can be found within the intestinal areas of animals and fish as well as in the gills and viscera of crabs along with other seafood. Such naturally sourced cases of Clostridium botulinum bacteria and spores are usually relatively harmless. Problems only usually arise once the spores transform into vegetative cells and also the cell population increases to the stage in which the bacteria begin creating botulinum contaminant, the deadly neurotoxin accountable for botox.

Neurotoxins concentrate on the central nervous system, disrupting the signaling processes that permit neurons to speak effectively. The neurotoxin involved with creating Botox treatment, botulinum contaminant (abbreviated either as BTX or BoNT), is subdivided into eight types A, B, C [C1, C2], D, E, F, G 18 and H.19

Of those, types A, B, E and, in rare cases, type F cause botox in humans, while types C and D cause illness in other animals, wild birds and fish.14 Although type G continues to be isolated from soil in Argentina, no outbreaks happen to be recognized concerning this contaminant.21

Type H is discovered in 2013 within the feces of a kid struggling with botox. Scientists withheld the particular DNA sequence of type H from public databases, as there wasn’t any known antidote for which they deemed would be a novel kind of botulinum contaminant.19 Subsequently, Scientists in the Cdc and Prevention (CDC) and also the College of Wisconsin (UW) discovered that type H may actually ‘t be a manuscript contaminant, having a paper printed within the Journal of Infectious Illnesses (JID) confirming the contaminant could be blocked by antitoxins already being used.25

How does botox work?

Botulinum contaminant is among the most poisonous substances available. Researchers have believed that the single gram could kill as much as a million people and also of kilos could kill every human on the planet.22 In high levels, botulinum contaminant can lead to botox, a serious, existence-threatening illness. Botox, not treated, may lead to respiratory system failure and dying.16 Despite botulinum contaminant being so toxic and thus pricey, Botox treatment is within huge demand.

Botox injection
Botulinum toxin is injected to treat certain muscular conditions and cosmetically remove wrinkles by temporarily paralyzing muscles.

Botulinum toxin has proven to be a successful and valuable therapeutic protein when dosage, frequency of treatment and variety of treated clinical conditions are considered.23

“Only the dose makes a remedy poisonous”20

Botulinum contaminant could be injected into humans in very small levels and functions by stopping signals in the nerve cells reaching muscles, effectively departing the muscles without instructions to contract, therefore paralyzing them.24

To ensure that muscles to contract, nerves to produce chemical messenger, acetylcholine (a natural chemical), in the junction in which the nerve being meet muscle tissues. The acetylcholine attaches to receptors around the muscle tissues and results in muscle cells to contract or shorten. Injected botulinum contaminant prevents the discharge of acetylcholine, stopping contraction from the muscle tissues. The result of botulinum contaminant causes a decrease in abnormal muscle contraction permitting the muscles to get less stiff.

Medical and cosmetic uses of botox

Botulinum contaminant is mainly utilized as a therapy to lessen the look of facial facial lines and wrinkles in older grown ups. Beyond aesthetic programs, Botox treatment has been discovered helpful in dealing with a number of health conditions including eye squints, migraines, excess sweating and leaking bladders. Botulinum contaminant is presently accustomed to treat over 20 different health conditions, with increased programs under investiation.

Botulinum toxin is currently approved for the following therapeutic applications:

  • Blepharospasm (spasm of the eyelids)1
  • Idiopathic rotational cervical dystonia (severe neck and shoulder muscle spasms) 1
  • Chronic migraine3
  • Severe primary axillary hyperhidrosis (excessive sweating)1
  • Strabismus (crossed eyes)1
  • Post-stroke upper limb spasticity4
  • Detrusor overactivity urinary incontinence6
  • Overactive bladder5
  • Hemifacial spasm1
  • Glabellar lines (frown lines between the eyebrows)2
  • Canthal lines (crow’s feet).7

Botulinum toxin is also often used off-label for:

  • Achalasia (an esophageal issue causing symptoms such as difficulty swallowing)8
  • Anal fissure and Anismus (dysfunction of the anal sphincter)8
  • Sialorrhea (hypersalivation)9
  • Allergic Rhinitis10
  • Sphincter of oddi (hepatopancreatic) dysfunction11
  • Cerebral Palsy1
  • Oromandibular dystonia (forceful contraction of the jaw, face and/or tongue)12
  • Laryngeal Dystonia (forceful contraction of the vocal cords).13

How is the botox procedure performed?

Botox injection into apple
Botuilinum toxin takes up to 72 hours to take effect and make a noticeable difference.

Botulinum contaminant is given by diluting the powder in saline (sodium chloride) and injecting it straight into neuromuscular tissue. It requires 24-72 hrs for botulinum contaminant to work, which reflects time required for the contaminant to disrupt the synaptosomal process. In unusual conditions, it might take as lengthy as five days for that full aftereffect of botulinum contaminant to become observed.14

Botulinum contaminant shouldn’t be utilized in pregnant or breast feeding women, or by those who have were built with a previous allergic attack towards the drug or any one of its components.

Risks and side effects of botox

Injections with botulinum contaminant are usually well tolerated and you will find couple of negative effects. In rare cases a person might possess a genetic temperament that produces a mild, transient unusual reaction to the drug.

Around 1% of individuals receiving injections of botulinum contaminant type A develop antibodies towards the contaminant which make subsequent remedies ineffective.26 In people given botulinum contaminant type B for cervical dystonia, antibody development continues to be seen as much as 44% of patients.

And its intended effects, botulinum contaminant could cause some undesirable effects. These may include:14,15

  • Mild pain, local edema and/or erythema at the injection site
  • Transient numbness
  • Headache
  • Malaise
  • Mild nausea
  • Temporary unwanted weakness/paralysis of nearby musculature caused by the action of the toxin
  • Temporary upper lid or brow ptosis (drooping)
  • Weakness of the lower eyelid or lateral rectus (a muscle controlling eye movement)
  • Dysphagia
  • Neck weakness
  • Influenza-like illness
  • Brachial plexopathy (a condition affecting the nerves either side of the neck and chest)
  • Gallbladder dysfunction
  • Diplopia (double vision)
  • Bleeding
  • Blurred vision
  • Drooping of the eyelids
  • Decreased eyesight
  • Dry mouth
  • Fatigue
  • Hives
  • Rashes
  • Wheezing
  • Swelling.

Botox treatment helps migraines “just a littleInch

Using botulinum contaminant A (Botox treatment) injections for chronic migraine sufferers enables them to “just a littleInch, and doesn’t seem to be the astonishing therapy many people believe or claim so that it is, scientists in the Medical College of Wisconsin, Milwaukee reported in JAMA (Journal from the Ama). The authors added that Botox treatment wasn’t much better than placebo in stopping chronic-tension-type headaches or episodic migraine.

New compound may safeguard from the deadly contaminant botulinum

Two kinds of botulinum contaminant – onabotulinumtoxinA and abobotulinumtoxinA – for crow’s ft, in comparison

It seems most sufferers say they’ve better is a result of abobotulinumtoxinA once they contract their face muscles, compared to onabotulinumtoxinA – when muscles were at relaxation there wasn’t any record difference, scientists in the Maas Clinic, Bay Area, and also the College of California, reported in Archives of Facial Cosmetic Surgery.

Botox treatment boosts flexibility, elasticity of skin for approximately 4 several weeks

New research printed within the journal JAMA Facial Cosmetic Surgery finds that botox treatment may enhance the flexibility and elasticity of skin for approximately 4 several weeks.

Botulinum toxin’s recognition is constantly on the increase, with cosmetic minimally-invasive botulinum contaminant type A methods up 700 percent since 2000, to six.3 million in 2013.17
