Prilosec vs Prevacid
Introduction
For patients dealing with gastroesophageal reflux disease (GERD) or other types of stomach acid-related conditions, certain drugs that reduce the production of gastric acid can help in soothing symptoms and preventing further complications. Prilosec and Prevacid are two such medications often prescribed to treat these conditions. They each inhibit different proton pumps in the stomach lining, but both effectively decrease gastric acid production aiding in ulcer healing and symptom management. Prilosec, known as omeprazole, acts by selectively inhibiting the H+/K+ ATPase enzyme system found at the secretory surface of parietal cells. On the other hand, Prevacid or lansoprazole belongs to a class of antisecretory compounds called proton pump inhibitors (PPIs), specifically suppressing gastric acid secretion by specific inhibition of this enzyme system at the final step in gastric acid production.
What is Prilosec?
Omeprazole (the generic name for Prilosec) was the first drug of the proton pump inhibitor (PPI) class, which marked a significant advance from the earlier class of drugs known as H2 receptor antagonists. Omeprazole was first approved by the FDA in 1989. Prilosec works by reducing the amount of acid produced in the stomach, effectively “trapping” less acid in the stomach than usual. It is prescribed for the treatment of various forms of acid-related conditions such as GERD, ulcers, and Zollinger-Ellison syndrome. Prilosec has a selective influence on the proton pumps of the stomach lining with minor influence on other bodily systems, which results in it having fewer side effects than other acid-reducing drugs that have stronger effects on these other systems. On the other hand, Lansoprazole (the generic name for Prevacid) is also a proton pump inhibitor but was introduced later, in 1995. It works in a similar way to Prilosec but may have slightly different effects on certain symptoms or conditions, so the choice between these two medications often depends on individual patient factors.
What conditions is Prilosec approved to treat?
Prilosec is approved for the treatment of various gastric acid-related disorders, including:
- Gastroesophageal reflux disease (GERD)
- Erosive esophagitis
- Zollinger-Ellison syndrome
- Prevention and treatment of duodenal ulcers caused by H. pylori infection when used in conjunction with appropriate antibiotic therapy.
How does Prilosec help with these illnesses?
Prilosec works to manage gastroesophageal reflux disease (GERD) and other conditions caused by excess stomach acid by decreasing the amount of this acid produced in the stomach. It does this through blocking a type of cell within your stomach, known as proton pumps, from producing and releasing acid into your digestive tract. Stomach acid plays an important role in breaking down food for digestion but too much can lead to symptoms such as heartburn, indigestion, and gastric ulcers among others. Therefore, by reducing the production of this acid with Prilosec, it helps to alleviate these negative effects allowing patients manage their condition more effectively.
Similarly, Prevacid also decreases the amount of acid produced in the stomach but has a slightly different chemical makeup which might make it more suitable for certain individuals based on factors like existing medical conditions or potential interactions with other medication they might be taking. It's always recommended that you discuss these options with your healthcare provider who can guide you towards making informed decisions about managing such conditions.
What is Prevacid?
Prevacid, which is a brand name for lansoprazole, operates as a proton pump inhibitor (PPI). This means it works by reducing the production of stomach acid. It accomplishes this by blocking the enzyme in the wall of the stomach that produces acid. Lansoprazole was first approved by the FDA in 1995 and can be used to treat conditions such as ulcers, gastroesophageal reflux disease (GERD), and Zollinger-Ellison syndrome. As a proton pump inhibitor, Prevacid does not inhibit H2 receptors or antihistamines. Its specific action on proton pumps means its side-effect profile differs from other types of heartburn relief medications; specifically, it has been linked to lower risks of causing drowsiness or cognitive impairment — common side effects with H2 antagonists like cimetidine (Tagamet). The effect on gastric acid secretion can be beneficial for treating heartburn symptoms and preventing damage to the esophagus caused by stomach acid.
What conditions is Prevacid approved to treat?
Prevacid, also known as lansoprazole, is recognized and approved for the treatment of several gastrointestinal conditions. These include:
- Gastroesophageal reflux disease (GERD)
- Stomach and duodenal ulcers
- Erosive esophagitis (damage to the esophagus from stomach acid)
- Zollinger-Ellison Syndrome
How does Prevacid help with these illnesses?
Prevacid acts as a proton pump inhibitor (PPI) which effectively reduces the production of stomach acid, making it highly beneficial in treating conditions like gastroesophageal reflux disease (GERD), ulcers, and Zollinger-Ellison syndrome. Prevacid works by blocking a specific enzyme on the gastric cell wall responsible for secreting stomach acid. Therefore, less acid is produced within your stomach allowing ulcers to heal and preventing new ones from forming. Its effect may also contribute to symptom relief in GERD such as heartburn or regurgitation. While it shares these characteristics with Prilosec, Prevacid has been shown to have a slightly faster onset of action which can be significant for patients seeking immediate relief.
How effective are both Prilosec and Prevacid?
Both omeprazole (Prilosec) and lansoprazole (Prevacid) are well-established proton pump inhibitors (PPIs), used primarily to treat conditions caused by excess stomach acid, such as gastroesophageal reflux disease. Approved by the FDA just a few years apart in the late 1980s to mid-1990s, these two drugs work by reducing production of gastric acid. The effectiveness of omeprazole and lansoprazole in alleviating symptoms associated with peptic ulcers was directly studied in various double-blind clinical trials; both drugs exhibited similar efficacy and promising safety profiles.
A comprehensive review of studies conducted on omeprazole since its introduction reveals that it is effective at providing symptomatic relief from acidity-related disorders within the first week of treatment. Its side effects are generally mild, making it tolerable even for elderly populations or those with comorbidities. Omeprazole has been widely prescribed globally due to its effectiveness and acceptable safety profile.
Similarly, numerous reviews have indicated that lansoprazole is also more effective than placebo at treating acidity related disorders and comparable in effect to other PPIs like omeprazole. Although typically considered as an equivalent alternative rather than a first-line choice over other PPIs like omeprazole, significant research indicates its efficacy as stand-alone therapy for gastric-acid related ailments including GERD and peptic ulcer disease. In certain cases where patients might not respond well or have contraindications towards one PPI medication due to specific health circumstances or drug interactions, they may be switched between different types such as from Prilosec to Prevacid or vice versa.
At what dose is Prilosec typically prescribed?
Oral dosages of Prilosec range from 20-40 mg/day, with most people finding relief from persistent heartburn and other related conditions with a daily 20 mg dose. For children and adolescents, the starting dosage is usually around 10 mg/day. If there's no response after several weeks, the dosage can be adjusted as necessary under medical supervision. However, in any case, the maximum dosage that should not be exceeded is 40 mg/day.
Prevacid doses typically vary between 15 to 30 mg per day based on individual needs but often a single daily dose of 15mg is enough for many adults dealing with stomach ulcers or gastroesophageal reflux disease (GERD). Pediatric doses are calculated specifically for each child by their healthcare provider. It's important to note that one should always adhere strictly to prescribed doses — exceeding the recommended maximum limit could lead to adverse effects.

At what dose is Prevacid typically prescribed?
Prevacid treatment is usually initiated at a dose of 15 mg daily for up to eight weeks. If symptoms persist or recur after this initial period, the dosage can be increased to 30 mg per day. This dose should be taken once in the morning before eating. For users with severe conditions like gastric ulcers, erosive esophagitis or pathological hypersecretory conditions, doses may go as high as 60 mg/day divided into two doses spaced approximately 12 hours apart. It's recommended that adjustments above this level should only take place under close physician supervision and after careful evaluation of therapeutic response.

- For Lansoprazole (generic Prevacid), costs can start from around $0.50 per day and reach close to $2 per day based on pack size and dosage.
Overall, generics offer significant savings over their branded counterparts while providing equivalent relief from acid reflux symptoms.
Popularity of Prilosec and Prevacid
Omeprazole, available as the brand name Prilosec, was estimated to have been prescribed to about 15.3 million people in the US in 2020. Omeprazole accounted for roughly 30% of proton pump inhibitor (PPI) prescriptions in the US. This medication is widely used for treating gastroesophageal reflux disease (GERD), peptic ulcer disease, and Zollinger-Ellison syndrome. The prevalence of omeprazole has remained steady over recent years.
Lansoprazole known by its brand name Prevacid, was prescribed to approximately 7 million individuals in the USA during that same year. In terms of PPI prescriptions within America, lansoprazole accounts for nearly a fifth at around 18%. Besides being effective against conditions similar to those treated with omeprazole like GERD and peptic ulcers; it's also utilized for certain bacterial infections involving the stomach lining such as Helicobacter pylori infection treatment regimens which can include combinations with antibiotics.
Conclusion
Both Prilosec (omeprazole) and Prevacid (lansoprazole) have a well-established history of use in managing conditions related to excess stomach acid, such as gastroesophageal reflux disease (GERD), peptic ulcers, and Zollinger-Ellison syndrome. Both medications belong to the class of drugs known as proton pump inhibitors (PPIs), which function by decreasing the amount of acid produced in the stomach.
Due to their similar mechanisms of action, they are often prescribed interchangeably or based on patient preference or cost considerations. Both Prilosec and Prevacid come in generic forms that offer patients considerable savings.
Like most medications, both Prilosec and Prevacid may require an adjustment period wherein full effects might not be immediately noticeable; it could take several days before users notice a significant decrease in symptoms.
The side effect profile is generally comparable between these two PPIs, with common side effects including headaches, nausea, diarrhea or constipation. However, long-term use can result in certain risks like vitamin B12 deficiency and bone fractures among others. As always when starting new treatment regimens for chronic conditions such as GERD or peptic ulcer disease; patients should closely monitor their symptoms and seek immediate medical attention if they notice any worsening condition or severe adverse reactions.
