abstract：:Simultaneous administration of psychostimulants and opioids is a major drug abuse problem worldwide. This combination appears to produce synergistic effects on behavior at low doses; however, there is little direct evidence that the combination is stronger than either drug alone. Therefore, we investigated interaction...

abstract：:Antihistamines inhibit histamine signaling by blocking histamine H1 receptor (H1R) or suppressing H1R signaling as inverse agonists. The H1R gene is upregulated in patients with pollinosis, and its expression level is correlated with the severity of nasal symptoms. Here, we show that antihistamine suppressed upregulat...
