Acute, Sub-chronic and Chronic Toxicity Studies

Analyzing the toxicity of drugs at different exposure levels

Syngene’s full range of general toxicology services supported by complete toxicokinetic analysis and interpretation services help clients analyze the toxic effects of drugs at various exposure levels. We leverage our in-house expertise on small and large molecule bioanalysis, formulation analysis, clinical and anatomic pathology services, and other disciplines to conduct toxicity studies with integrated endpoints. We deliver faster and cost-efficient results and provide comprehensive and integrated study reports.


Syngene’s experts evaluate the toxicity of drugs and provide dosing recommendations by conducting acute single-dose studies and repeat-dose based sub-acute, sub-chronic, and chronic toxicity studies, involving various species, administration routes, dosage, exposure levels, and methods.
