Amneal Resumes Shipping of Axid® Equivalent Nizatidine Oral Solution

Only oral liquid formulation available

BRIDGEWATER, N.J.-- Amneal Pharmaceuticals, Inc. (NYSE: AMRX) today announced that its nizatidine oral solution 15 mg/mL (75 mg/5 mL) is now available for reorder. The drug, the generic equivalent of Axid®, is the only oral liquid form of nizatidine available in the US. The Amneal product meets all FDA requirements and specification limits related to NDMA.

“Nizatidine has been a trusted active ingredient for over 30 years," said Joe Todisco, Executive Vice President, Chief Commercial Officer for the Amneal Specialty Division that distributes the product. “Patients, prescribers and pharmacists have seen their treatment options dwindle, which is why we are so pleased to bring the oral liquid formulation back to market.”

Nizatidine Oral Solution manufactured by Amneal, is a prescription oral product used for the short-term treatment and maintenance therapy of ulcers and for the treatment of esophagitis and associated heartburn due to gastroesophageal reflux disease (GERD). Nizatidine Oral Solution is contraindicated in patients with known hypersensitivity to the drug or with a history of hypersensitivity to other H2- receptor antagonists. The Amneal product is available as a peppermint-flavored liquid sold in 480 mL bottles. Click here for full prescribing information.

Indications and Usage

In adult patients, nizatidine is indicated for:

• Up to 8 weeks for the treatment of active duodenal ulcer. In most patients, the ulcer will heal within 4 weeks.

• Maintenance therapy for duodenal ulcer patients at a dosage of 150 mg/daily at bedtime after healing of an active duodenal ulcer.

• Up to 12 weeks for the treatment of endoscopically diagnosed esophagitis, including erosive and ulcerative esophagitis, and associated heartburn due to GERD.

• Up to 8 weeks for the treatment of active benign gastric ulcer. Before initiating therapy, care should be taken to exclude the possibility of malignant gastric ulceration.

In pediatric patients ages 12 years and older, nizatidine oral solution is indicated for:

• Up to 8 weeks for the treatment of endoscopically diagnosed esophagitis, including erosive and ulcerative esophagitis, and associated heartburn due to GERD.

Important Safety Information


Nizatidine oral solution is contraindicated in patients with known hypersensitivity to the drug or with a history of hypersensitivity to other H2-receptor antagonists.


Symptomatic response to nizatidine therapy does not preclude the presence of gastric malignancy. Because nizatidine is excreted primarily by the kidney, dosage should be reduced in patients with moderate to severe renal insufficiency.

Adverse Reactions (adult)

In placebo-controlled trials, anemia (0.2% vs 0%) and urticaria (0.5% vs 0.1%) were significantly more common in the nizatidine group compared to the placebo group. The only adverse event that occurred in >10% of patients receiving nizatidine was headache. Adverse events that occurred in 3% to 10% of patients were pain, asthenia, diarrhea, dizziness, insomnia, rhinitis, and pharyngitis.

Adverse Reactions (pediatric)

In controlled clinical trials in pediatric patients (aged 2 to 18 years), adverse experiences that occurred in >5% of patients were pyrexia, nasopharyngitis, diarrhea, vomiting, irritability, nasal congestion, and cough. Most adverse events were mild or moderate in severity. Mild elevations in serum transaminase (1 to 2 ULN) were noted in some patients. Adverse reactions reported for nizatidine may also occur with nizatidine oral solution. 

Use in Specific Populations

Pregnancy and Nursing Mothers: Only use nizatidine during pregnancy and while nursing if it is clearly needed.

Pediatric Use: Effectiveness in pediatric patients <12 years of age has not been established.

Geriatric Use: Differences in responses between the elderly and younger patients have not been identified, but greater sensitivity of some older individuals cannot be ruled out. Elderly patients are more likely to have decreased renal function. Select doses carefully and consider monitoring renal function.
