'Morse et al. [7] have demonstrated the effects of GHB on breathing. A decrease in respiratory rate occurs, accompanied by a compensatory increase in tidal volume, allowing minute volume to be maintained until doses approach lethality. The concomitant ingestion of ethanol typically alters the concentration-effect relationship, leading to respiratory depression when the compensatory increase in tidal volume is avoided as seen in cases where GHB is administered alone. This deleterious effect from combining GHB and ethanol could be avoided through the administration of GABA-B receptor antagonists. These receptors seem to be involved in its development.'
