What is the answer to the dose?
dose-response is a correlation relationship between the level of exposure to and reactions to it. The relationship of dose-reaction is an important topic in pharmacology and toxicology and is often expressed in the form of a mathematical curve that renders the level of dosing and response to information. This relationship can be very important when people determine when the exposure level exceeds the "safe" to "dangerous" boundary. It assumes that the exposure level is so low, in which the response cannot be measured or mapped, and a certain point at which the exposure level is so high that there will be no further reaction. In a simple example, someone would expose one dose of X -rays during the dental test would not develop an answer, but it is possible to kill someone with a high dose of X -rays, demonstrating the TON two extremes of the dose reaction curve.
Several factors are linked in the dose-response relationship. The volume of the dose is a problem, but also timelessof it. For example, there is a difference between obtaining dental X -rays every two years over 20 years and obtaining dental X -rays every day for 10 days. In this case, the number of exposures is the same, but the reaction to the dose is different because the patient was in one case exposed to X -rays spread over for a long time and in the other on a series of X -rays in rapid succession.
In the development of new drugs, one of the things scientists examine is the dose-response relationship. They are looking for a balance point on a curve where people respond to medicines but do not experience harmful side effects. In some cases, people may be forced to endure the harsh side effects, as seen in chemotherapy, while in other cases the doses can be maintained low and carefully targeted to avoid problems, as seen in low -dose hormonal contraceptives.
Toxicologists are also extremely interested in this topic. They are interested in how toxin levels affect populations during the course ofTime, and at this point, different groups in the population begin to prove reactions. These scientists can deal with topics such as bioaccumulation in which toxins accumulate in the body instead of processing, along with the effects of cumulative exposure. In order to borrow an X -ray example, most medical patients are not endangered by health problems due to an X -ray exposure, as they receive low doses at occasional intervals. Medical experts who serve X -rays or work on X -ray machines are on the other hand endangered as a result of a cumulative exposure.
