Pantoprazole vs Lansoprazole
Introduction
For individuals suffering from gastroesophageal reflux disease (GERD) or other types of peptic ulcer diseases, certain medications that reduce the production of gastric acid can help in managing symptoms and promoting healing. Pantoprazole and Lansoprazole are two such drugs that are commonly prescribed for these conditions. They each inhibit a specific enzyme in the stomach lining called proton pump, which is responsible for acid secretion. Both have beneficial effects in patients with gastric-acid related disorders. Pantoprazole belongs to a class known as proton pump inhibitors (PPIs), effectively reducing levels of stomach acid by blocking the action of the enzyme. Similarly, Lansoprazole also falls under PPIs; it acts on similar pathways but has different pharmacokinetic properties with slightly quicker absorption rate.
What is Pantoprazole?
Pantoprazole, the generic name for Protonix, is a proton pump inhibitor (PPI) that was introduced as a significant advancement over H2 blockers used to decrease stomach acid production. Pantoprazole was first approved by the FDA in 2000. It works by blocking an enzyme in the wall of your stomach that produces acid, thus decreasing levels of acidity and allowing ulcers or erosions to heal more effectively. It's primarily prescribed to treat gastroesophageal reflux disease (GERD), Zollinger-Ellison syndrome and other conditions involving excessive stomach acid.
In contrast, Lansoprazole (Prevacid) acts similarly but has some differences in terms of metabolism and interaction with other drugs since it gets metabolized more extensively via cytochrome P450 system compared to pantoprazole thereby having potential for drug interactions. Both have similar side effects profiles including headache, diarrhea, nausea but their effect can vary from person to person due to individual variability.
What conditions is Pantoprazole approved to treat?
Pantoprazole is approved for the treatment of several gastric acid-related disorders:
- Gastroesophageal reflux disease (GERD)
- Erosive esophagitis
- Zollinger-Ellison syndrome
- Prevention and maintenance of healing erosive esophagitis.
How does Pantoprazole help with these illnesses?
Pantoprazole works to manage conditions related to excess stomach acid by decreasing the amount of gastric secretions available in the lining of the stomach. It does this by inhibiting a type of enzyme known as proton pumps, which are primarily responsible for producing these gastric acids. Gastric acid is a digestive fluid formed in the stomach that is key in digesting food and protecting against harmful bacteria, but an overabundance can result in conditions like gastroesophageal reflux disease (GERD), ulcers, and heartburn. Individuals suffering from such conditions may have relatively higher levels of gastric acid secretion or sensitivity towards it. Therefore, by reducing these secretions through pantoprazole intake, patients can limit damage to their esophagus or stomach lining and achieve relief from discomfort or pain caused due to excessive acidity.
What is Lansoprazole?
Lansoprazole, marketed under the brand name Prevacid among others, is a proton pump inhibitor (PPI) that decreases stomach acid production. It works by blocking an enzyme in the wall of the stomach that produces acid. This can be beneficial in treating conditions such as gastroesophageal reflux disease (GERD), peptic ulcers and Zollinger-Ellison syndrome where excessive acidity is problematic.
The drug was first approved by the FDA in 1995 and comes in several forms including dissolvable tablets, capsules, and injections for intravenous use. While Lansoprazole does not inhibit any particular neurotransmitter like bupropion does serotonin, its side-effect profile also differs from those of other similar medications such as Pantoprazole: it may cause diarrhoea or constipation but is less likely to produce nausea or headaches. The effects on gastric acid secretion reduction can be especially helpful for patients who do not find relief with H2 receptor antagonists or antacids.
What conditions is Lansoprazole approved to treat?
Lansoprazole is a medication that has gained approval for the treatment of several conditions, which include:
- Gastroesophageal reflux disease (GERD)
- Stomach and duodenal ulcers
- Zollinger-Ellison syndrome, an uncommon disorder characterized by high levels of stomach acid production
How does Lansoprazole help with these illnesses?
Lansoprazole is a type of medication known as a proton pump inhibitor (PPI), which works by reducing the amount of acid produced in the stomach. This action helps alleviate symptoms and heal damage caused by gastroesophageal reflux disease (GERD) or other conditions associated with excessive stomach acid. Like pantoprazole, lansoprazole binds to the proton pumps within the stomach lining, blocking the final step in acid production. However, lansoprazole has been noted for its rapid first-pass metabolism and shorter plasma half-life compared to other PPIs like pantoprazole. Because it acts quickly and does not remain in effect as long, it may be preferred for patients who need immediate but not prolonged relief from excess gastric acid.
How effective are both Pantoprazole and Lansoprazole?
Both pantoprazole and lansoprazole are proton pump inhibitors (PPIs) with established track records of effectively managing and treating gastroesophageal reflux disease (GERD), peptic ulcers, and other conditions related to excess stomach acid. They were both approved by the FDA in the 1990s. As they block the same enzyme that produces gastric acid, they can be prescribed under similar circumstances. The efficacy of pantoprazole and lansoprazole in controlling GERD symptoms has been directly compared in numerous clinical trials; findings suggest comparable effectiveness between these two PPIs as well as promising safety profiles.
A 2009 meta-analysis reported on multiple studies comparing PPIs like pantoprazole and lansoprazole for healing erosive esophagitis, finding that all reviewed PPI drugs demonstrated high rates of healing at eight weeks with no significant differences among them.
A 2018 review indicated that while most PPIs seem equally effective when taken correctly before meals, patients' adherence to instructions can vary greatly impacting their effectiveness. Nonetheless, where strict adherence is difficult or not possible due to lifestyle factors or patient preference, a more flexible dosing schedule may be advisable – here Pantaprazoles’ longer half-life could be advantageous.
Lastly, it's worth noting there are some distinct considerations: for example Lansoprozale’s use over Pantaprozale in paediatric populations due to its availability as an orally disintegrating tablet which doesn't require swallowing a pill.
At what dose is Pantoprazole typically prescribed?
Oral dosages of Pantoprazole range from 20-40 mg/day, with studies showing that a typical dosage of 40 mg/day is effective for treating gastroesophageal reflux disease in most adults. Children and adolescents may start on a reduced dose depending on their weight and the severity of symptoms. After several weeks, if there is insufficient response to treatment, your doctor may consider increasing the dosage or switching to another medication. The maximum dosage that should not be exceeded is generally 120 mg/day under specialized medical supervision.

At what dose is Lansoprazole typically prescribed?
Lansoprazole treatment typically begins with a dosage of 15 mg per day, but can be increased to 30 mg per day depending upon the medical condition and how well the patient responds to therapy. This medication is usually taken once daily before meals; it should not be consumed in larger amounts or for longer than recommended by a healthcare professional. For chronic conditions such as stomach ulcers or gastroesophageal reflux disease (GERD), patients may need to take Lansoprazole for several months. If there is no response to treatment at an initial dose after a few weeks, talk to your doctor about possibly increasing the dosage.
What are the most common side effects for Pantoprazole?
Side effects of Pantoprazole can include:
- Headache
- Diarrhea
- Nausea or vomiting
- Stomach pain
- Gas, bloating or flatulence
- Joint pain
- Dizziness
While side effects of Lansoprazole may include:
- Constipation or diarrhea
- Dizziness, fatigue or weakness
- Nausea and stomach pain
- Skin rash, itching
Are there any potential serious side effects for Pantoprazole?
While both Pantoprazole and Lansoprazole are proton pump inhibitors used to treat acid reflux and stomach ulcers, they come with their own set of potential side effects.
For Pantoprazole, these can include:
- Signs of a serious allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue or throat
- New or worsening symptoms of lupus - joint pain and a skin rash on your cheeks or arms that worsens in sunlight.
- Kidney problems - urinating less than usual, blood in your urine, swelling in your feet or ankles
- Low magnesium levels - dizziness, fast or irregular heart rate; tremors (shaking) or jerking muscle movements; feeling jittery; muscle cramps

Remember to seek immediate medical attention if any adverse effects occur while using either medication.
What are the most common side effects for Lansoprazole?
Lansoprazole, a proton pump inhibitor used to reduce stomach acid, can cause the following side effects:
- Dry or sore throat
- Nausea, vomiting, abdominal pain or constipation
- Diarrhea
- Headache or dizziness
- Fatigue and sleep issues (insomnia)
- Skin reactions such as rash or itching
- Musculoskeletal problems like joint pain and muscle cramps.
It's also worth noting that long-term use of Lansoprazole may lead to vitamin B12 deficiency which could potentially result in weight loss due to poor appetite. However, these symptoms tend not to be common and most people tolerate Lansoprazole quite well. As always individuals should consult their healthcare provider for personalized advice regarding medication options.
Are there any potential serious side effects for Lansoprazole?
Lansoprazole is usually well-tolerated, but like any medication, it may cause adverse effects. Some of the serious side effects associated with this drug include:
- Signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue or throat
- Kidney problems - urinating less than usual, blood in your urine, swelling in your feet or ankles
- Symptoms suggestive of low magnesium levels such as unusually fast/slow/irregular heartbeat, persistent muscle spasms and seizures
- Severe diarrhea that is watery or bloody
- Unexplained weight loss
- Bone fractures (especially if you take the medicine long term)
If you experience any of these symptoms while taking lansoprazole, seek immediate medical attention.
Contraindications for Pantoprazole and Lansoprazole?
Both Pantoprazole and Lansoprazole, like most other Proton Pump Inhibitors (PPIs), may cause symptoms such as nausea, vomiting, or diarrhea in some people. If you experience these or worsening stomach discomfort after taking either of these medications, please seek immediate medical attention.
Neither Pantoprazole or Lansoprazole should be taken if you are currently on an HIV protease inhibitor such as atazanavir. Always inform your doctor about the medications you are taking; certain medicines require a specific period to clear from your system before starting PPI therapy to prevent dangerous interactions with Pantoprazole and Lansoprazole.
Furthermore, long-term use of PPIs can lead to low magnesium levels in the body. If you're on either medication for more than a year and notice signs of muscle spasms or irregular heartbeat; consult with your healthcare provider immediately.
How much do Pantoprazole and Lansoprazole cost?
For the brand name versions of these drugs:
- The price of 30 tablets of Protonix (40 mg), which is a brand name for pantoprazole, averages around $250, working out to approximately $8.33/day.
- The price of 30 capsules of Prevacid (15 mg), a brand name for lansoprazole, is about $200, which translates to roughly $6.67/day.
Thus, if you are taking either drug at their respective doses as mentioned above, then branded lansoprazole (Prevacid) could be less expensive on a per-day treatment basis than pantoprazole (Protonix). However, remember that cost should not be your primary consideration in determining which medication best suits your needs.
For the generic versions:
- Pantoprazole (40 mg tablets) can range from $0.25 to $2.50 per pill depending on where it's purchased and whether you're buying in bulk or individually.
- Lansoprazole comes in different dosage forms including orally disintegrating tablet form with costs ranging between $0.80 and up to more than over two dollars per dose depending on dosage strength and packaging size.
Again note that prices may vary widely based upon location and pharmacy used as well as any insurance coverage or discounts available to you.
Popularity of Pantoprazole and Lansoprazole
Pantoprazole, both in generic form and under brand names such as Protonix, was estimated to have been prescribed to about 14 million people in the US in 2020. Pantoprazole accounted for approximately 32% of proton pump inhibitor (PPI) prescriptions in the US. Pantoprazole has been a popular choice amongst PPIs since its approval by FDA in 2000.
Lansoprazole, including brand versions like Prevacid, was prescribed to around 4 million people in the USA during the same period. Lansoprazole accounts for roughly 10% of all PPI prescriptions and is recognized for its efficiency against gastric ulcers caused by H.pylori infections when used with other antibiotics. The use of lansoprazole has remained relatively stable over the last decade.
Conclusion
Both Pantoprazole and Lansoprazole have a long history of usage in the treatment of gastroesophageal reflux disease (GERD), peptic ulcer disease, and other conditions associated with excess stomach acid. They are part of the proton pump inhibitor class, working by reducing gastric acid production within the stomach's parietal cells. While both drugs are effective, they may be used interchangeably depending on individual patient factors and physician preference.
Pantoprazole is often chosen for its once-daily dosing regimen which can improve compliance among patients who find multiple daily doses challenging. On the other hand, Lansoprazole is available as an over-the-counter medication in many countries making it more accessible to some patients.
As generic versions exist for both medications, cost should not be a significant deciding factor between these two options. Both pantoprazole and lansoprazole typically start showing results rapidly but optimal effect may take several days to weeks due to their mechanism of action.
The side-effect profiles for pantoprazole and lansoprazole are quite similar with common side effects including diarrhea, nausea, vomiting, constipation and headache. Serious side effects such as fractures from long-term use or Clostridium difficile-associated diarrhea are extremely rare but possible. Like any medication changes or new symptoms after starting either drug should prompt timely consultation with a healthcare provider.
