Abstract
Tacrine belongs to the group of acetylcholinesterse (AChE) inhibitors used as drugs for treatment of Alzheimers disease (AD). The formation of hydroxyderivatives of tacrine is well-established step in the metabolization of this drug in liver by microsomal cytochrome P450 enzymes family. Genetic polymorphism of cytochrome P450 enzymes is probably responsible for balance between a number of stable and non-toxic metabolites and highly protein-reactive and toxic ones. By this manner may be explained why the hepatotoxicity of tacrine was observed only in the part of persons and why not every patient with AD responds to the treatment by this drug.

Interaction between drugs and endocrine diseases
The introduction of highly active antiretroviral therapy accelerated studies and our understanding on the interaction between pharmacological therapies and endocrine diseases. Drugs can precipitate endocrine via different mechanisms, including direct alteration of hormone production and secretion, dysregulation of hormonal axis, effects on hormonal transport, receptor-binding, and cellular signalling. Common drug-induced ...read more
