Psychopharmacology

The psychopharmacology ( from Ancient Greek ψῡχή, ps ȳ Che, for " soul "; φάρμακον, pharmakon, for " drug" and λογία, logia, for " teaching" ) goes back to Emil Kraepelin and examines the effects of so-called drugs on the nervous system and the experience and behavior. Agents are exogenous chemical substances that are not necessary for normal cell function, but may cause effects on the physiological level and experience and behavior. The interesting for psychopharmacologists of action of a drug is the central nervous system (CNS). An active ingredient enters into the central nervous system, in that it is administered intravenously, intraperitoneally, intramuscularly or subcutaneously, reaches the blood plasma after a certain time and then to overcome the so-called blood -brain barrier. Has an active ingredient to overcome the blood- brain barrier, it can act on the central nervous system. It is crucial for psychopharmacologists the way in which an active ingredient:

• The storage and release of neurotransmitters
• To the pre-and post-synaptic receptors, and
• The re- uptake and degradation of neurotransmitters

Acts in the CNS and the effects are related to experience and behavior level with it.
