Amityville-based Hi-Tech Pharmacal Co. Inc. has gotten federal approval to sell a generic version of Zantac syrup, a treatment for duodenal ulcers.

The U.S. Food and Drug Administration granted final approval for ranitidine syrup, the generic for GlaxoSmithKline’s Zantac.

The potential annual market for ranitidine syrup, a treatment for heartburn or acid reflux, is about $21 million, the company said.

Ranitidine is a histamine-2 receptor antagonist (a group often called H2 blockers) that is prescribed to reduce stomach acid. These include cimetidine (Tagamet), famotidine (Pepcid), nizatidine (Axid) and ranitidine (Zantac).

A report in December indicated that popular acid-reduction drugs, including proton pump inhibitors and histamine-2 receptor antagonists, may raise the risk of pneumonia.
