Phototoxicity assays
Shedding Light on Drug-Induced Phototoxicity!
As we develop new medications, it's essential to ensure they don't lead to adverse reactions when exposed to sunlight. That's where phototoxicity assays come into play. These tests help us understand how drugs can trigger harmful reactions when exposed to UV or visible light.
Methods for assessing phototoxicity
1. One common method involves using human skin cell models, like reconstructed skin tissue or cell cultures. By exposing these cells to the drug and light, we can evaluate the potential for phototoxic reactions. These assays not only aid in predicting adverse effects but also guide formulation changes to minimise risks.
2. Use of real human tissues allows for the most complex understanding of UV induced effects on human skin.
Here at Alcyomics we have a range of epidermal, Full thickness 3D tissue and skin explant models for use on UV exposure tests.
Our readouts for UV exposure assays include melanin quantification alongside quantification of damage induction, changes in matrix composition, epidermal thickness, cytokine release, RNA sequencing among many others.
Understanding drug-induced phototoxicity is crucial for various industries, including pharmaceuticals, cosmetics, and even environmental safety. By identifying potential hazards early on, we contribute to safer products and a healthier environment.
