We next investigated no matter whether YHS could also be helpful in already-dependent animals and could, therefore, potentially be used to curb the opioid epidemic. For tolerance reversal, mice have been treated for 3 days with morphine (two.5 mg/kg twice every day), followed by four days of YHS (250 mg/kg) or YHS + morphine (250 mg/kg and 2.5 mg/kg, respectively) and then tested for analgesic tolerance (Figure five). YHS alone or in combination with morphine reverses morphine tolerance and restores analgesia in previously tolerant animals.Figure 5.
