Produktbeschreibung
Opioid addiction is a major public health
problem and the need for new efficient therapies is
immense.18-Methoxycoronaridine (18-MC), an iboga
alkaloid congener, has been previously shown to
reduce the self-administration of several drugs of
abuse, including opioids.18-MC is a potent
antagonist of alpha3beta4 nicotinic receptors and
this now appears to be the primary mechanism of 18-
MC s action in the brain. These nicotinic receptors
are present in high densities in the nuclei of the
habenulo-interpeduncular pathway but
not in the mesolimbic pathway, known to be involved
in drug addiction.This book describes the modulation
of the mesolimbic pathway by the habenulo-
interpeduncular pathway during chronic exposure to
opioids and examines the role of 18-MC, nicotinic
receptors and acetylcholine in such modulation.This
book also illustrates the contribution of the latter
pathway in 18-MC s ability to attenuate opioid
withdrawal.The findings described in the book
provide evidence that alpha3beta4 nicotinic
receptors could be a novel target for anti-addictive
therapies.The monograph should be useful to
pharmacologists and behavioral neuroscientists.
