The prescriber's guide to classic MAO inhibitors (phenelzine, tranylcypromine, isocarboxazid) for treatment-resistant depression.

This article is a clinical guide which discusses the "state-of-the-art" usage of the classic monoamine oxidase inhibitor (MAOI) antidepressants (phenelzine, tranylcypromine, and isocarboxazid) in modern psychiatric practice. The guide is for all clinicians, including those who may not be experienced MAOI prescribers. It discusses indications, drug-drug interactions, side-effect management, and the safety of various augmentation strategies.

A neurotensin analog blocks cocaine-conditioned place preference and reinstatement.

Neurotensin (NT) is a neuropeptide that acts as a neurotransmitter and neuromodulator in the central nervous system. Several studies suggest a therapeutic role for NT analogs in nicotine and other psychostimulant addictions. We studied the effects of the nonselective NT receptor agonist NT69L, which has equal affinity for the two major NT receptors, NTS1 and NTS2, on the expression of cocaine-conditioned place preference (cocaine-CPP) and reinstatement after extinction.

Elucidating the role of neurotensin in the pathophysiology and management of major mental disorders.

Neurotensin (NT) is a neuropeptide that is closely associated with, and is thought to modulate, dopaminergic and other neurotransmitter systems involved in the pathophysiology of various mental disorders. This review outlines data implicating NT in the pathophysiology and management of major mental disorders such as schizophrenia, drug addiction, and autism. The data suggest that NT receptor analogs have the potential to be used as novel therapeutic agents acting through modulation of neurotransmitter systems dys-regulated in these disorders.

Neurotensin agonist attenuates nicotine potentiation to cocaine sensitization.

Tobacco usage typically precedes illicit drug use in adolescent and young adult populations. Several animal studies suggest nicotine increases the risk for subsequent cocaine abuse, and may be a negative prognostic factor for treatment of cocaine addiction; i.e.
