Losec vs Lansoprazole Capsule: Which one is better?

Losec and Lansoprazole differ mainly in their chemical composition. Over the years, Doctors have been able to compare the effect of Omeprazole and Esomeprazole on the acid levels in the stomach.

Losec contains the active substance omeprazole. It belongs to a group of medicines called 'proton pump inhibitors'. These drugs work by reducing the amount of acid made by the stomach.

Losec is used to treat the following diseases in adults:

  • Gastroesophageal reflux disease (GERD). In this disorder, acid from the stomach passes into the oesophagus (the tube that connects the throat to the stomach), causing pain, inflammation, and burning.
  • Ulcers in the upper part of the intestine (duodenal ulcer) or in the stomach (gastric ulcer).
  • Ulcers infected by a bacterium called "Helicobacter pylori". If you have this disease, your doctor may also prescribe antibiotics to treat the infection and allow the ulcer to heal.
  • Ulcers caused by medicines called NSAIDs (non-steroidal anti-inflammatory drugs). Losec can also be used to prevent ulcers from forming if you are taking NSAIDs.
  • Excess acid in the stomach caused by a tumour in the pancreas (Zollinger-Ellison syndrome).


The active substance in lansoprazole is lansoprazole, a proton pump inhibitor. Proton pump inhibitors decrease the amount of acid your stomach makes.

Your doctor may prescribe lansoprazole for the following indications in adults:

  • Treatment of ulcer of the duodenum and stomach.
  • Treatment of inflammation of the oesophagus (reflux esophagitis).
  • Prevention of inflammation of the oesophagus (reflux esophagitis).
  • Treatment of heartburn and acid regurgitation (passage of acid content rising from the stomach).
  • Treatment of infections caused by the Helicobacter pylori bacteria, in combination with antibiotics.
  • Treatment or prevention of duodenal or stomach ulcer in patients who require continuous treatment with non-steroidal anti-inflammatory drugs (NSAIDs) (treatment with NSAIDs is used for pain or inflammation).
  • Treatment of Zollinger-Ellison syndrome.
  • Losec and Lansoprazole (whose main active ingredients are Omeprazole and Esomeprazole, respectively) differ mainly in their chemical composition. Over the years, many studies have been conducted to compare the effect of Losec and Lansoprazole on acid levels in the stomach.


Lansoprazole provides more effective acid control: According to studies, a standard dose of 40 mg of Lansoprazole provides better acidity control than Losec in the same dose.

Lansoprazole 40 mg works better than Losec 20 mg: Compared to Losec 20 mg, Lansoprazole 40 mg keeps the acid pH in the stomach at 4 for longer. What does this mean? Lower pH means lower acidity and fewer bothersome reflux symptoms.

Lansoprazole offers relief even in severe conditions: Studies have shown that Lansoprazole relieves symptoms of heartburn and acid reflux in patients with severe GERD for a period of 4 to 8 weeks. What's more, almost 8 out of 10 people who received Lansoprazole did not have heartburn overnight.

Lansoprazole provides relief from symptoms for 24 hours: Evidence suggests that taking Lansoprazole for 4 weeks can provide relief from heartburn during the day and at night.

Lansoprazole works better than most other PPIs: Lansoprazole has been shown to provide faster healing of symptoms compared to Lansoprazole, another PPI. Lansoprazole works just as well as dexlansoprazole to help with heartburn and to treat GERD.

Lansoprazole is a much more effective PPI for treating GERD and is therefore the treatment option for most doctors. If you want to purchase either Omeprazole Losec capsules or Lansoprazole Capsule Online in the UK, search no further than Pharmacy planet.
