Thanks.
Checked their website, http://tajpharma.com/lactulose-generics-taj-pharmaceuticals.htm
Still get the impression that they are selling the finished dosage, not the bulk lactulose solution which Lactose India is going to produce.
To see the difference check these 2 links, note the unit field.

We are mostly importing lactulose solution in bulk (by tonnes) and selling them in btl (100/200 ML), tablet forms etc.
