In vivo Early Safety Assessment


In vivo Safety Evaluation during Drug Discovery

For early safety and toxicity assessment, Pharmacology Discovery Services has over 30 years of experience conducting in vivo safety and early toxicity testing. Combined with the in vitro pharmacology and cell based in vitro toxicity services from our Partner Lab, Eurofins Pharma Discovery Services, our in vivo safety services can provide a comprehensive risk profile for your drug candidates at a stage when changes can still be met without a major impact to your project

We offer a complete list of qualified safety related in vivo models to detect the most commonly observed adverse events in CNS, cardiovascular, respiratory, renal, metabolic, and gastrointestinal functions using a broad panel of industry-standard outcome measures to build a toxicokinetic (TK) profile.  We can also provide specialized models, such as our emesis model, to address specific project needs.
