The Dose-Response Relationship

The dose-response relationship describes how the body reacts to different amounts of a substance, such as a drug or toxin. Essentially, it shows that as the dose increases, the body's response typically becomes stronger or more noticeable, up to a certain point. For example, a small amount of pain medication may relieve mild pain, while a higher dose might relieve more severe pain. However, beyond a certain dose, additional benefits might plateau or cause harm. This relationship helps determine safe and effective dosage levels to maximize benefits while minimizing risks.
