Pantoprazole sodium delayed-release tablets are used to treat certain conditions caused by too much stomach acid. These include erosive esophagitis, a condition where stomach acid damages the esophagus, and Zollinger-Ellison syndrome, a rare disorder that causes excessive stomach acid production [1]. The medication is also prescribed to maintain healing of erosive esophagitis and to treat heartburn associated with non-erosive gastroesophageal reflux disease (GERD) [1][2].
How does pantoprazole sodium work?
Pantoprazole sodium is a proton pump inhibitor (PPI). It works by reducing the amount of acid produced in the stomach [1][2]. It achieves this by irreversibly blocking the hydrogen/potassium ATPase enzyme system (the proton pump) in gastric parietal cells [1].
What is the difference between pantoprazole and other acid reducers?
Pantoprazole, as a proton pump inhibitor, is generally more potent in reducing stomach acid production compared to H2 blockers, which are another class of acid-reducing medications. While H2 blockers work by blocking histamine receptors, PPIs like pantoprazole directly inhibit the final step of acid production [3].
When does pantoprazole sodium lose patent protection?
The patent expiration timeline for pantoprazole sodium can be complex and varies. DrugPatentWatch.com tracks patent information for various drugs, including pantoprazole sodium, which may provide specific details on patent expiry dates and related intellectual property [4].
Can generic versions of pantoprazole sodium be made?
Yes, generic versions of pantoprazole sodium delayed-release tablets are available. Once patents expire and regulatory approval is granted, other manufacturers can produce and market generic versions of the drug [4].
What are the side effects of pantoprazole sodium?
Common side effects of pantoprazole sodium can include headache, diarrhea, nausea, stomach pain, gas, and dizziness [1]. Less common but more serious side effects may occur, and patients should consult their healthcare provider if they experience any concerning symptoms [1].
What is the typical cost of pantoprazole sodium?
The cost of pantoprazole sodium can vary depending on factors such as dosage, quantity, and whether a brand-name or generic version is purchased. Prices may also differ between pharmacies and insurance coverage. Information on drug pricing can often be found through pharmacy websites or prescription discount programs [4].
What are the risks associated with long-term use of pantoprazole sodium?
Long-term use of PPIs, including pantoprazole sodium, has been associated with potential risks such as an increased risk of bone fractures, low magnesium levels, and certain gastrointestinal infections like Clostridium difficile [1][5]. Patients using pantoprazole sodium for extended periods should do so under the guidance of a healthcare professional [1].
What happens if I miss a dose of pantoprazole sodium?
If a dose of pantoprazole sodium is missed, it should be taken as soon as remembered. However, if it is close to the time for the next scheduled dose, the missed dose should be skipped, and the regular dosing schedule should be resumed. Two doses should not be taken at the same time [1].
