Dl50

Title: "Dl50: what does it mean?"

Dl50 (lethal dose, average) is an indicator that is used in pharmacology to determine the toxicity of a drug or its effect when a certain dose is administered.

This concept was developed by John Snow in the late 19th century to assess the dangers of medications and drugs. At that time, doctors began to take the dangers of drug abuse more seriously and looked for new ways to reduce their side effects.

Snow's classic experiment involved giving laboratory animals the same dose of a substance and observing their response to it. If all the animals died or showed very severe symptoms, then the substance was considered relatively safe and toxic.
