Pharmacology vs toxicology

Toxicology is a science that studies the poison characteristics of a substance and also its adverse effects on living beings. But, in areas like drug research, both pharmacology and toxicology are employed. However, the role of these two studies is different yet vital. Pharmacology vs Toxicology Differences

Hazards related to a drug have to be identified and the potential risks at the intended exposure have to be evaluated in comparison to the potential benefit of the drug. Pharmacology degrees are more research-focused, teaching you how to investigate chemical effects and create new remedies. Toxicology degrees are similar to pharmacology, but instead focus on the toxic (rather than the healing) properties of venoms, poisons, and drugs.

The median lethal dose is the dose required to kill 50% of subjects. The therapeutic index is the ratio of the TD 50 to the ED 50 , a parameter which reflects the selectivity of a drug to elicit a desired effect rather than toxicity.This program is jointly sponsored by the Department of Pharmacology and Toxicology and the School of the Environment.
