Gabbroral (also known as Gabroral) is an aminoglycoside antibiotic containing paromomycin sulfate, used primarily for intestinal infections. Historically, it has been prescribed for:

  • Intestinal amebiasis
  • Giardiasis
  • Tapeworm infections

The drug acts locally in the gastrointestinal tract with minimal systemic absorption, reducing ammonia-producing bacteria.

Although Gabbroral is absent from the U.S. Food and Drug Administration (FDA) Orange Book and European Medicines Agency’s (EMA) central database, it may still be marketed under national authorizations in some regions, including:

  • Belgium
  • Luxembourg
  • Egypt
  • Kenya
  • Uganda

In the USA, paromomycin is available only as generics following discontinuation of the Humatin brand.
