Mechanism
How it works
Amlexanox acts like a fire extinguisher for mouth ulcers — it quickly puts out the inflammatory fire, numbs the area, and accelerates healing.
Amlexanox is a small-molecule peptide analog that inhibits phosphodiesterase and leukotriene synthesis, reducing mucosal inflammation and pain.

In depth
Full profile
What it does
Sores heal fast. About 2-3 days instead of 7-10 days on their own.
How it works
Think of it like a fire extinguisher for mouth sores. It puts out the swelling fast, numbs the spot, and helps it heal.
It blocks the body signals that cause swelling. This calms the puffy, sore parts of your mouth.
What to expect
Pain feels better in a few hours. Sores heal in 2-4 days.
- Day 1: Less pain and burning.
- Day 2-3: You can see the sore getting smaller.
- Day 4-5: Small sores are all healed up.
Good to know
- Put it on a clean, dry sore
- Try not to swallow the paste
Staying safe
- A little sting when you put it on
- Food may taste a bit funny for a short time
Avoid if you have:
- People who get a bad reaction to it
- People with active cold sores (they need a different fix)
Mechanism of action
Amlexanox is a small-molecule peptide analog that inhibits phosphodiesterase and leukotriene synthesis, reducing mucosal inflammation and pain.
Inhibits PDE4 and PDE3, reduces TNF-α and leukotriene B4 in mucosal tissue.
Pharmacodynamics
Pain relief within hours; healing in 2-4 days.
Rapid ulcer healing (2-3 days vs 7-10 days naturally).
Timeline
- Day 1: Reduced pain and burning.
- Day 2-3: Visible ulcer shrinkage.
- Day 4-5: Complete healing of small ulcers.
