Clinicians use drug detoxification to reduce or relieve withdrawal symptoms while helping an addicted person adjust to living without drug use. Drug detoxification does not aim to treat addiction but rather represents an early step within long-term treatment. Detoxification may be achieved drug-free or may use medications as an aspect of treatment.
The "Hepatic Extraction Ratio" is a similar measurement for clearance of a substance (usually a pharmacological drug) by the liver. It is defined as the fraction of drug removed from blood by the liver, and depends on 3 factors— the hepatic blood flow, the uptake into the hepatocytes, and the enzyme metabolic capacity.
In the short-term, such detox diet may lead to weight loss, due to the strict caloric restriction, however after returning to a normal diet there is a weight gain. [19] Although a brief fast of a single day is unlikely to cause harm, prolonged fasting (as recommended by certain detox diets) can have dangerous health consequences or can even be ...
This may also be called standard range. In contrast, optimal (health) range or therapeutic target is a reference range or limit that is based on concentrations or levels that are associated with optimal health or minimal risk of related complications and diseases. For most substances presented, the optimal levels are the ones normally found in ...
Some addiction medicine practitioners use the term withdrawal management instead of detoxification. [ 1 ] [ 2 ] A detoxification program for physical dependence does not necessarily address the precedents of addiction , social factors, psychological addiction, or the often-complex behavioral issues that intermingle with addiction.
Oxidative stress mechanisms in tissue injury. Free radical toxicity induced by xenobiotics and the subsequent detoxification by cellular enzymes (termination).. Oxidative stress reflects an imbalance between the systemic manifestation of reactive oxygen species and a biological system's ability to readily detoxify the reactive intermediates or to repair the resulting damage.

Drug metabolism is the metabolic breakdown of drugs by living organisms, usually through specialized enzymatic systems. More generally, xenobiotic metabolism (from the Greek xenos "stranger" and biotic "related to living beings") is the set of metabolic pathways that modify the chemical structure of xenobiotics, which are compounds foreign to an organism's normal biochemistry, such as any drug ...
The LD 50 values have a very wide range. The botulinum toxin as the most toxic substance known has an LD 50 value of 1 ng/kg, while the most non-toxic substance water has an LD 50 value of more than 90 g/kg; a difference of about 1 in 100 billion, or 11 orders of magnitude. As with all measured values that differ by many orders of magnitude, a ...
