The concentration-response relationship describes how the magnitude of a biological or toxicological effect varies with the concentration of a substance. It is fundamental in pharmacology and toxicology for determining the dose at which a substance produces a therapeutic or harmful effect.

Pharmacology is the branch of medicine that focuses on the study of drugs and their effects on living organisms, encompassing the development, chemical properties, and therapeutic applications of pharmaceutical agents. It plays a crucial role in understanding how drugs interact with biological systems to treat, prevent, or diagnose diseases, ensuring their safety and efficacy.

Pharmacology

Toxicology is the scientific study of the adverse effects of chemical substances on living organisms and the practice of diagnosing and treating exposures to toxins and toxicants. It involves understanding the dose-response relationship, mechanisms of toxicity, and assessing risk to ensure safety in pharmaceuticals, environmental chemicals, and consumer products.

Toxicology

The therapeutic effect refers to the beneficial outcomes of a treatment or intervention, typically resulting in symptom relief or disease improvement. It is a critical measure in evaluating the efficacy of medical treatments, encompassing both intended and sometimes unintended positive outcomes.
