What are the uses of this medicine?[edit | edit source]

  • Lansoprazole (Prevacid; Prevacid SoluTab; Prevacid 24HR) is used:

In Adults:

  • 4 weeks for the healing and symptom relief of duodenal ulcers.
  • 10 to 14 days with certain antibiotics to treat an infection caused by bacteria called H. pylori.
  • maintaining healing of duodenal ulcers. Lansoprazole delayed-release capsules have not been studied beyond 12 months for this purpose.
  • up to 8 weeks for the healing and symptom relief of stomach ulcers.
  • up to 8 weeks for the healing of stomach ulcers in people taking pain medicines called nonsteroidal anti-inflammatory drugs (NSAIDs). Lansoprazole delayed-release capsules have not been studied beyond 8 weeks for this purpose.
  • reducing the risk of stomach ulcers in people who are at risk of developing stomach ulcers with NSAIDs. Lansoprazole delayed-release capsules have not been studied beyond 12 weeks for this purpose.
  • up to 8 weeks to treat heartburn and other symptoms that happen with gastroesophageal reflux disease (GERD). GERD happens when acid in your stomach backs up into the tube (esophagus) that connects your mouth to your stomach. This may cause a burning feeling in your chest or throat, sour taste or burping.
  • up to 8 weeks for the healing and symptom relief of acid-related damage to the lining of the esophagus (called erosive esophagitis or EE). Your doctor may prescribe another 8 to 16 weeks of lansoprazole delayed-release capsules for patients whose EE does not improve or whose symptoms return.
  • maintaining healing of EE. Lansoprazole delayed-release capsules have not been studied beyond 12 months for this purpose.
  • the long-term treatment of conditions where your stomach makes too much acid. This includes a rare condition called Zollinger-Ellison syndrome.

In children 1 to 11 years of age, lansoprazole delayed-release capsules are used for:

  • up to 12 weeks to treat heartburn and other symptoms that can happen with GERD.
  • up to 12 weeks for the healing and symptom relief of EE.

In children 12 to 17 years of age, lansoprazole delayed-release capsules are used for:

  • up to 8 weeks to treat heartburn and other symptoms that can happen with GERD.
  • up to 8 weeks for the healing and symptom relief of EE.
  • Lansoprazole delayed-release capsules are not recommended for treating the symptoms of GERD in children less than 1 year of age and may harm them.

How does this medicine work?[edit | edit source]

  • Lansoprazole (lan soe' pra zole), like other PPIs, binds to and inactivates the hydrogen/ potassium (H+/K+) ATPase of gastric parietal cells, causing inhibition of the proton pump that transports H+ into the gastric lumen, the final common step in gastric acid production.
  • Lansoprazole is a prodrug and is converted to the active form in the acidic secretory canaliculi of parietal cells.
  • Because the inhibition is irreversible, acid secretion is suppressed for 24 to 48 hours, until new proton pump molecules have been synthesized and transported to the cell membrane.

Who Should Not Use this medicine ?[edit | edit source]

What special precautions should I follow?[edit | edit source]

  • In adults, symptomatic response with lansoprazole does not preclude the presence of gastric malignancy. Consider additional follow-up and diagnostic testing.
  • Acute tubulointerstitial nephritis (TIN) has been observed in patients taking PPIs and may occur at any point during PPI therapy. Discontinue lansoprazole delayed-release capsules and evaluate patients with suspected acute TIN.
  • Lansoprazole delayed-release capsules may be associated with an increased risk of Clostridium difficile-associated diarrhea (CDAD), especially in hospitalized patients. Patients should use the lowest dose and shortest duration of PPI therapy appropriate to the condition being treated.
  • PPI therapy may be associated with an increased risk for osteoporosis-related fractures of the hip, wrist or spine. Patients at risk for osteoporosis-related fractures should be managed according to established treatment guidelines.
  • Severe cutaneous adverse reactions, including Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN), drug reaction with eosinophilia and systemic symptoms (DRESS), and acute generalized exanthematous pustulosis (AGEP) have been reported. Discontinue lansoprazole delayed-release capsules at the first signs or symptoms of severe cutaneous adverse reactions or other signs of hypersensitivity and consider further evaluation.
  • Cutaneous lupus erythematosus (CLE) and systemic lupus erythematosus (SLE) have been reported in patients taking PPIs, including lansoprazole. Discontinue lansoprazole and refer to specialist for evaluation.
  • Daily treatment with any acid-suppressing medications over a long period of time (e.g., longer than three years) may lead to malabsorption of cyanocobalamin (Vitamin B12) caused by hypo- or achlorhydria.
  • Hypomagnesemia, symptomatic and asymptomatic, has been reported rarely in patients treated with PPIs for at least three months, in most cases after a year of therapy. Consider monitoring magnesium and calcium levels prior to initiation of lansoprazole delayed-release capsules. Supplement with magnesium and/or calcium, as necessary. If hypocalcemia is refractory to treatment, consider discontinuing the PPI.
  • Serum chromogranin A (CgA) levels increase secondary to drug-induced decreases in gastric acidity. Healthcare providers should temporarily stop lansoprazole treatment at least 14 days before assessing CgA levels and consider repeating the test if initial CgA levels are high.
  • PPI use is associated with an increased risk of fundic gland polyps that increases with long-term use, especially beyond one year. Use the shortest duration of PPI therapy appropriate to the condition being treated.
  • Lansoprazole is not approved in pediatric patients less than one year of age.
  • Concomitant use with PPIs may elevate and/or prolong serum concentrations of methotrexate and/or its metabolite, possibly leading to toxicity. With high-dose methotrexate administration, consider a temporary withdrawal of lansoprazole delayed-release capsules.
  • Lansoprazole therapy is associated with a low rate of transient and asymptomatic serum aminotransferase elevations and is a reported, but very rare cause of clinically apparent liver injury.
  • There is no information regarding the presence of lansoprazole in human milk, the effects on the breastfed infant, or the effects on milk production.
