A psychotropic drug is an active substance that alters brain function. This substance consists of a molecule or its active metabolites, which must meet two essential criteria. They must be able to cross the blood-brain barrier to reach the brain and have a certain affinity for one or more sites of action. Their effects result from their binding to these targets and the subsequent modifications.

摘要

A psychotropic drug is an active substance that alters brain function. This substance consists of a molecule or its active metabolites, which must meet two essential criteria. They must be able to cross the blood-brain barrier to reach the brain and have a certain affinity for one or more sites of action. Their effects result from their binding to these targets and the subsequent modifications.
