Reverse tolerance or drug sensitization is a pharmacological phenomenon describing subjects' increased reaction (positive or negative) to a drug following its repeated use. [4] Not all drugs are subject to reverse tolerance. This is the opposite of drug tolerance, in which the effect or the subject's reaction decreases following its repeated ...
A medical intervention that has an objective to increase tolerance (e.g., allergen immunotherapy, in which one is exposed to larger and larger amounts of allergen to decrease one's allergic reactions) is called drug desensitization. [8] The opposite concept to drug tolerance is reverse tolerance, in which case the subject's reaction or effect ...
The last image we have of Patrick Cagey is of his first moments as a free man.

Released from alpha cells in the pancreas either when starving or when the body needs to generate additional energy; it stimulates the breakdown of glycogen in the liver to increase blood glucose levels; its effect is the opposite of insulin; glucagon and insulin are a part of a negative-feedback system that stabilizes blood glucose levels ...
Upregulation of receptors, on the other hand, can result in super-sensitized cells, especially after repeated exposure to an antagonistic drug or prolonged absence of the ligand. Some receptor agonists may cause downregulation of their respective receptors, while most receptor antagonists temporarily upregulate their respective receptors.
Another reason is the instability and degradation of the drugs in gastro-intestinal environment. Serious problem is also variability between patients what causes different bioavailability after administration equal dose of a drug and different tolerance to effect of chemotherapy agents.
The correlation of aggressive drug law enforcement with escalating drug-related deaths is by no means limited to Florida. But Bondi's approach epitomizes what went wrong across the country.
Toxicity is the degree to which a chemical substance or a particular mixture of substances can damage an organism. [1] Toxicity can refer to the effect on a whole organism, such as an animal, bacterium, or plant, as well as the effect on a substructure of the organism, such as a cell (cytotoxicity) or an organ such as the liver (hepatotoxicity).
