What is Pantac?
Pantac is a proton pump inhibitor that decreases the amount of acid produced in the stomach.
Pantac is used to treat erosive esophagitis (damage to the esophagus from stomach acid caused by gastroesophageal reflux disease, or GERD) in adults and children who are at least 5 years old. Pantac is usually given for up to 8 weeks at a time while your esophagus heals.
Pantac is also used to treat Zollinger-Ellison syndrome and other conditions involving excess stomach acid.
Taking Pantac can lead to a kidney condition called acute interstitial nephritis. This may occur in people with a sensitivity to PPIs.
If a doctor detects this condition, they will stop the medication immediately.
What are the possible side effects of Pantac (Protonix, Protonix IV)?
Get emergency medical help if you have signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.
Call your doctor at once if you have:
- severe stomach pain, diarrhea that is watery or bloody;
- sudden pain or trouble moving your hip, wrist, or back;
- bruising or swelling where intravenous Pantac was injected;
- kidney problems--urinating less than usual, blood in your urine, swelling, rapid weight gain;
- low magnesium--dizziness, fast or irregular heart rate, tremors (shaking) or jerking muscle movements, feeling jittery, muscle cramps, muscle spasms in your hands and feet, cough or choking feeling; or
- new or worsening symptoms of lupus--joint pain, and a skin rash on your cheeks or arms that worsens in sunlight.
Taking Pantac long-term may cause you to develop stomach growths called fundic gland polyps. Talk with your doctor about this risk.
If you use Pantac for longer than 3 years, you could develop a vitamin B-12 deficiency. Talk to your doctor about how to manage this condition if you develop it.
Common side effects may include:
- headache, dizziness;
- stomach pain, gas, nausea, vomiting, diarrhea;
- joint pain; or
- fever, rash, or cold symptoms (most common in children).
This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
Some people taking warfarin with Pantac can experience increases in INR and prothrombin time (PT). This can lead to an increased risk of severe bleeding. If you take these drugs together, your doctor should monitor you for increases in INR and PT.
Clinical Trials Experience
The adverse reaction profiles for PROTONIX (Pantac sodium) For Delayed-Release Oral Suspension and PROTONIX (Pantac sodium) Delayed-Release Tablets are similar.
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.
7. Pregnancy and breastfeeding
Pantac isn't usually recommended during pregnancy as there's no firm evidence it's safe.
A medicine called omeprazole, which is similar to Pantac, is safe in pregnancy.
However, if you're pregnant, it's better to try to treat your symptoms without taking a medicine.
Your doctor or midwife may suggest eating smaller meals more often and avoiding fatty and spicy foods.
They may also suggest that you raise the head of your bed 10 to 20cm by putting something under your bed or mattress, so that your chest and head are above your waist. This helps stop stomach acid travelling up towards your throat.
If these lifestyle changes don't work, you may be recommended omeprazole, which is safe to take during pregnancy.
What is Pantac (Protonix)? How does it work (mechanism of action)?
Pantac is in a class of drugs called proton pump inhibitors (PPIs), which block the production of acid by the stomach. Other drugs in the same class include lansoprazole (Prevacid), omeprazole (Prilosec) and rabeprazole (Aciphex). Proton pump inhibitors are used for the treatment of stomach conditions such as duodenal and peptic ulcers, gastroesophageal reflux disease (GERD), and Zollinger-Ellison syndrome that are caused by stomach acid.
Pantac, like other proton-pump inhibitors, blocks the enzyme in the wall of the stomach that produces acid. By blocking the enzyme, the production of acid is decreased, and this allows the stomach and esophagus to heal.
The FDA approved Pantac in February 2000.
