Identification
- Summary
Ecamsule is a sunscreen agent found in sunscreens that absorbs UV rays.
- Generic Name
- Ecamsule
- DrugBank Accession Number
- DB09534
- Background
Ecamsule is an organic compound which is added to many sunscreens to filter out UVA rays. It is a benzylidene camphor derivative, many of which are known for their excellent photostability. Ecamsule has been approved for use in the U.S. since 2006, but only at a specific concentration and only in a few products manufactured by L'Oreal. The company got approval for those products through a new drug application process.

When exposed to UV ecamsule undergoes reversible photoisomerization followed by photoexcitation. The absorbed UV is then released as thermal energy, without penetrating the skin, thereby protecting the skin from UV exposure.
- Mechanism of action
Ecamsule protects against UV wavelengths in the 290–400 nanometer range, with peak protection at 345 nm. Ecamsule is photostable and it does not degrade significantly when exposed to light. In studies done in mice it reduces the formation of UV induced pyrimidine dimers and delays the onset of skin cancer. In vitro, ecamsule has been shown to effectively protect against the harmful effects of UV.
- Absorption
Ecamsule is a topical preparation, it should not be absorbed. Research done by L'Oreal on human subjects revealed that the systemically absorbed dose of [(14)C]-Ecamsule is less than 0.1% and under realistic exposure conditions, the human systemic exposure to this UVA filter is negligible and poses no risk to human health.
- Volume of distribution
Ecamsule is intended for topical application and has no volume of distribution.
- Protein binding
Ecamsule is intended for topical application only.
- Metabolism
Ecamsule is not absorbed or metabolized.
- Route of elimination
Ecamsule is intended for topical application only.
- Half-life
Ecamsule is not absorbed and has no reported half life data.
- Clearance
Ecamsule is used topically, it not absorbed or metabolized.
