Acute toxicity describes the adverse effects that occur from a single exposure or multiple exposures to a substance within a short timeframe, typically less than 24 hours [1.2.2, 1.2.1]. Understanding what is considered acute toxicity is vital for chemical safety and pharmacology.

According to the Globally Harmonized System (GHS) of classification, a substance can be designated as a **Category 1B toxicity**, which means there is strong evidence from animal studies suggesting a potential hazard to human health. This designation plays a critical role in drug development, handling protocols, and patient safety.
