Xanthinol Nicotinate

Also known as xanthinol niacinate and Complamin (commercial formulation).  Xanthinol nicotinate is a combination of xanthinol (a derivative of theophylline) and the B-vitamin niacin.  It’s considered to be a “smart drug” or nootropic, due to its ability to improve memory and microcirculation.  Flushing can occur with higher doses, although this reaction does not occur as frequently as it does w/niacin, its parent compound.
