Nifoxipam (3-hydroxydesmethylflunitrazepam, DP 370) is a benzodiazepine that is a minor metabolite of flunitrazepam and has been sold online as a designer drug.[1][2][3][4][5][6][7][8][9]

Nifoxipam produces strong tranquillising and sleep-prolonging effects and has much lower toxicity compared to lormetazepam and flunitrazepam in mice.[1]
