Most people prefer "-Lam" benzos which act mainly on a1 (addiction, amnesia, sedation, delusions of sobriety) and a5 (loss of executive function, the only site ethanol touches)
It does not fit into a1 , no affinity for a5, possible a3 (muscle relaxation) and a4 (antiepileptic). Sedative and those without dependence will find much stronger effects. Intended to more heavily affect 5ht in the way all 7-nitro bzd's do at high doses,. Affects stimulants physiological effects different than traditional benzos.
All nitro-bzds have a much smaller therapeutic index, this one may be even lower than clonazepam's ~250mg LD50. May significantly increase respiratory depression relative to intensity of pynazolam's effects.
