Could this be sulpiride which is marketed here under the brand name of Eglonyl.
 It comes in 50mg tablets, is distantly related to the phenothiazines, tends to
increase milk supply as a side effect to its "psychonormalizing" effect.  Used
a lot here by doctors for mothers with post partum depression &/or anxiety and
also if the doctor thinks her milk supply is low, whether or not she needs it
for the tranquilizing effect!
