Pax-2

I have some generic alprazolom, 2 mg, manufacturer says ========Pharmaceuticals.  They are small, white round with not markings on them.  They have a name of Pax-2 all over the blister cover.  Has anyone heard of or seen these or have any info about them.  They don't seem to work at all.

Thanks

please do not post online pharmacies names. g
