Answer

Neuromuscular Blockers, Botulinum Toxins

OnabotulinumtoxinA is used typically to treat muscle hypertonia and cosmetic disorders. Typically, onabotulinumtoxinA is injected into the internal sphincter, reducing hypertonia. Various dosing schemes have been used, and it is typically injected on both sides of the anal fissure. OnabotulinumtoxinA has been shown to be as effective as topical nitrates, but with fewer adverse effects, including headache, and can be an alternative to surgery.

OnabotulinumtoxinA (BOTOX)

OnabotulinumtoxinA is used typically to treat muscle hypertonia and cosmetic disorders. Typically, onabotulinumtoxinA is injected into the internal sphincter, reducing hypertonia.
