NMDA receptor antagonists neramexane

It is beheved that phenomena such as sensitization, tolerance and drug-dependence might also involve synaptic plasticity. In fact, numerous studies indicate that NMDA receptor antagonists block sensitization to amphetamine and cocaine as well as tolerance and dependence to ethanol and opioids in animal models (Trujillo and Akil 1991 Pasternak and Inturrisi 1995 Trujillo and Akil 1995 Mao 1999). Recent studies indicate that the uncompetitive NMDA receptor antagonists dextromethorphan, memantine and neramexane not only prevent the development of morphine tolerance, but also reverse estabhshed tolerance in the continuing presence of this opioid, prevent the expression of withdrawal symptoms in rats (Popik and Skolnick 1996 Popik and Danysz 1997 Popik and Kozela 1999 Houghton et al. 2001) and attenuate the expres-...
