Regulatory toxicology commonly is associated with government agencies. These agencies may vary dramatically in their size and scope. For example, the United Nations covers the entire globe, while agencies within a city are limited to the area covered by the municipality. Figure 5.1.1 5.1. 1: Introduction to regulatory toxicology.In Vivo Toxicology - Purpose •Results from preclinical toxicology studies should, at a minimum: –Establish a safe starting dose for clinical studies –Provide information on a drug-treatment regimen that would produce the least toxicity –Assess target organ toxicity and its reversibility –Provide insight into biomarkers for clinicalPharmacology is a science that studies the effect of a drug and the body’s response to it. It is aimed at bringing therapeutic benefits from the drug. Toxicology is a science that studies the poison characteristics of a substance and also its adverse effects on living beings.They are defined as follows: NOAEL — Highest dose at which there was not an observed toxic or adverse effect. LOAEL — Lowest dose at which there was an observed toxic or adverse effect. Figure 1 shows a dose-response curve where the NOAEL occurs at 10 mg and the LOAEL occurs at 18 mg. Figure 2.5.
Pharmacology is the study of how medicines work and how they affect our bodies.
