toxicity

Chronic toxicity studies are specialized assays designed to evaluate the potential adverse health effects resulting from repeated or continuous exposure to a substance over an extended period. These studies aim to characterize the long-term impact of such exposure on biological systems. 

Before a drug can enter clinical trials in humans, it must undergo rigorous safety evaluations to assess its potential risks. This includes identifying not only mild adverse effects, such as headaches or dizziness, but also identifying or predicting life threatening toxicities that may arise.
