"This unique volume traces the behavior of the drug substance, starting from the initial pre-contact stage, and ending with the formation of the complex. Molecular recognition lays in the foundation of every life form and includes many mysteries. Currently, studies on this topic in pharmacology are limited to determining the properties of complexes of medicinal substances (drugs) with specific (complementary) biomolecules: receptors, enzymes, ion channels etc. The results present the mechanisms preventing drugs from such non-specific binding. This direction is very fruitful, though the phenomenon of molecular recognition is far wider"--
