Pantoprazole's active ingredient is pantoprazole sodium [1]. It is formulated in various strengths, commonly 20 mg and 40 mg [2].
What are the inactive ingredients in pantoprazole?
The inactive ingredients in pantoprazole formulations can vary slightly depending on the specific product and manufacturer. However, common inactive ingredients found in pantoprazole tablets include:
* Coating agents: Such as hypromellose, polyethylene glycol, and titanium dioxide, which help protect the active ingredient and aid in tablet disintegration [1][3].
* Binders: Like povidone, which helps hold the tablet ingredients together [3].
* Fillers/Diluents: Such as calcium carbonate, mannitol, and microcrystalline cellulose, which add bulk to the tablet [1][3].
* Disintegrants: Such as crospovidone, which helps the tablet break apart in the digestive tract [1][3].
* Lubricants: Like magnesium stearate, which prevents the tablet ingredients from sticking to manufacturing equipment [1][3].
* pH modifiers: Such as sodium carbonate, to help control the tablet's micro-environment [1].
How does pantoprazole work in the body?
Pantoprazole is a proton pump inhibitor (PPI). It works by irreversibly blocking the H+/K+ ATPase enzyme system (the proton pump) in the parietal cells of the stomach [4]. This action significantly reduces the production of stomach acid [4].
What is pantoprazole used to treat?
Pantoprazole is used to treat conditions associated with excess stomach acid, including [4]:
* Gastroesophageal reflux disease (GERD)
* Erosive esophagitis
* Zollinger-Ellison syndrome
* Helicobacter pylori infection, when used in combination with antibiotics
When does pantoprazole patent protection end?
Drug patent expirations are a complex area. For pantoprazole, the original patents have long since expired, allowing for the widespread availability of generic versions [5]. Information on specific patent timelines and any subsequent extensions or challenges for pantoprazole can be found on resources like DrugPatentWatch.com [5].
What are the side effects of pantoprazole?
Common side effects of pantoprazole can include headache, diarrhea, nausea, abdominal pain, and dizziness [4]. Less common but more serious side effects can include bone fractures, kidney problems, and vitamin B12 deficiency with long-term use [4].
Are there alternatives to pantoprazole?
Yes, there are alternative medications for managing stomach acid issues. These include other proton pump inhibitors (PPIs) such as omeprazole, lansoprazole, and esomeprazole. Histamine-2 (H2) blockers like famotidine and ranitidine (though ranitidine has faced recalls and availability issues) are also used, as are antacids for immediate, short-term relief [6].
Who manufactures pantoprazole?
Pantoprazole is manufactured by numerous pharmaceutical companies worldwide, both for branded and generic versions. Major manufacturers of the branded version (Protonix) have included Pfizer and Takeda Pharmaceuticals. Generic pantoprazole is produced by many different companies [7].
What is the cost of pantoprazole?
The cost of pantoprazole varies significantly based on whether it is a branded or generic product, the dosage, the quantity purchased, and the pharmacy or insurance plan. Generic pantoprazole is generally much less expensive than the branded version [8].
Can you buy pantoprazole over-the-counter?
Yes, lower strengths of pantoprazole (e.g., 20 mg) are available over-the-counter (OTC) in many countries for the short-term treatment of frequent heartburn [9]. Higher strengths typically require a prescription.
