In other words, it estimates how different levels of exposure to a pollutant change the likelihood and severity of health effects. 3. Medical definition of dose-response: of, relating to, or graphing the pattern of physiological response to varied dosage (as of a drug or radiation) in which there is typically little or no effect at very low dosages and a toxic or unchanging effect at high dosages with the maximum increase in effect somewhere between the extremes. The same authors showed that the administered dose and duration of treatment did not have any effect on the metabolism of RSP to 9-OH-RSP. Physical activity, while not a drug, can behave like one—it causes many physiological changes in the body (often beneficial for health), 1 helps prevent the development of many chronic diseases, 2 and is a useful adjunct to drug treatment for many diseases, including cardiovascular disease, cancer, and diabetes. The term "dose-response curve" is occasionally used even more loosely to refer to experiments where you vary levels of some other variable, such as temperature or voltage.

In toxicology, studies of the dose given to test organisms is expressed in terms of The earlier segment of a biphasic plot of log C against t (following intravenous injection of a drug) represents the "distributive phase" of a drug's sojourn in the body. The dose-response relationship, or exposure-response relationship, describes the magnitude of the response of an organism, as a function of exposure (or doses) to a stimulus or stressor (usually a chemical) after a certain exposure time. Graded dose-response relationship Graphically visualizes differences in responses to medications in a single patient. The shape of the dose-response curve for toxic substances has been the topic of an enormous debate that began several decades ago and continues today (Calabrese 1978).The argument centers on whether there is a threshold below which no adverse effects would be expected or whether the dose-response relationship is linear, with risk being proportional to dose (Bingham 1971, Hatch 1971, 1972 . By contrast, the dosage is the prescribed administration of a specific amount, number, and frequency of doses over a specific period of time.

Typically applied or administered dose, rather than effective tissue dose, is used to develop the dose-response relationship. 16,40 Sattelmair et al 16 observed an inverse dose-response association between PA and CHD risk with a significant reductions in CHD risk with levels of PA at par with or even lower than the current guideline-recommended minimum . However, as with specificity (see below), the absence of a dose-response relationship does not rule out a causal relationship. Define a quantal dose-response relationship characterizes the distribution of responses to different doses in a population of individual organisms; it's all or none situation (eg determination of the median lethal dose for a chemical; whether patient responds or not to treatment) Mechanism involve effect on many cells in these the severity of response is proportional to dose these are cell killing occur in all people when the dose is larger enough.
