Hepatotoxicity and drug-induced liver injury also account for a substantial number of compound failures, highlighting the need for toxicity prediction models (e.g. DTI), [2] and drug screening assays, such as stem cell-derived hepatocyte-like cells, that are capable of detecting toxicity early in the drug development process. [3]
A hepatotoxin (Gr., hepato = liver) is a toxic chemical substance that damages the liver.. It can be a side-effect, but hepatotoxins are also found naturally, such as microcystins and pyrrolizidine alkaloids, or in laboratory environments, such as carbon tetrachloride, or far more pervasively in the form of ethanol (drinking alcohol).

Toxins and medications can cause liver injury through a variety of mechanisms, including direct cell damage, disruption of cell metabolism, and causing structural changes. [38] Some drugs such as paracetamol exhibit predictable dose-dependent liver damage while others such as isoniazid cause idiosyncratic and unpredictable reactions that vary ...
Nevirapine may cause severe or life-threatening liver toxicity, usually emerging in the first six weeks of treatment. [ 25 ] [ 27 ] In 2000, the U.S. Food and Drug Administration issued a black box warning on nevirapine, warning that it could cause life-threatening liver toxicity and skin reactions. [ 4 ]
Tolcapone has demonstrated significant liver toxicity (hepatotoxicity) [13] that limits the drug's utility. Entacapone is an alternative, largely since it has a more favorable toxicity profile. The hepatotoxicity can be related to elevated levels of transaminases , but studies have shown that minimal risk exists for those without preexisting ...
Prescription nicotinic acid was shown to cause hepatotoxicity [16] and increase risk of type 2 diabetes. [17] [18] nicotinic acid prescriptions in the U.S. had peaked in 2009 at 9.4 million, declining to 800 thousand by 2020. [19] Nicotinic acid has the formula C 6 H 5 NO 2 and belongs to the group of the pyridinecarboxylic acids. [5]
Using cloned α 1 G, α 1 H, and α 1 I T-type calcium channels, Gomora's team found that ethosuximide blocked the channels with an IC 50 of 12 ± 2 mmol/L and that of N-desmethylmethsuximide (the active metabolite of mesuximide) is 1.95 ± 0.19 mmol/L for α 1 G, 1.82 ± 0.16 mmol/L for α 1 I, and 3.0 ± 0.3 mmol/L for α 1 H. It was ...
