Liver, heart, kidney and brain drug-induced toxicities currently account for more than 70% of drug attrition and drug withdrawal. Porsolt together with Fluofarma has developed a range of organ-specific cell-based assays to better predict the toxicity potential of drug candidates prior to in vivo studies.

Based on highly predictive cellular models, i.e. primary cell cultures, Fluofarma perform functional toxicity assays and offer to investigate the signaling pathways involved in detoxification and oxidative stress and induced by the drug compound.
