What other trade names may exist by country?

Lactulose is available under multiple brand names that vary by country and manufacturer. If you share your country (or the exact product label you saw), I can help identify the specific lactulose trade name used there.

Yes. Trade names can differ, but if the active ingredient on the label is lactulose (and the dosage form matches, like oral solution or syrup), it is the same active drug.
