From the Research
The latest effective Proton Pump Inhibitors (PPIs) available in the Indian market include Esomeprazole, Rabeprazole, Pantoprazole, Omeprazole, and Dexlansoprazole, with Esomeprazole being the most effective option due to its superior acid suppression and faster onset of action, as demonstrated in a study published in 2016 1.
Key Points to Consider
- Esomeprazole (20-40mg daily) and Rabeprazole (20mg daily) are considered among the most effective options with faster onset of action and better acid suppression.
- PPIs work by irreversibly blocking the hydrogen/potassium ATPase enzyme system in gastric parietal cells, reducing stomach acid production by up to 99% 2.
- For most acid-related disorders, these medications are typically prescribed for 4-8 weeks, though maintenance therapy may continue longer for conditions like GERD or peptic ulcers.
- Newer formulations include delayed-release and dual-release technologies that improve bioavailability.
- Patients should be aware that long-term use (beyond 8-12 weeks) should be monitored by a physician due to potential side effects like vitamin B12 deficiency, increased fracture risk, and kidney problems.
Comparison of PPIs
- A study published in 2005 compared the inhibitory effect of tenatoprazole and esomeprazole on intragastric acidity, and found that tenatoprazole provided a prolonged duration of acid suppression and a shorter nocturnal acid breakthrough 3.
- Another study published in 2003 compared the 24-h intragastric pH profile of oral esomeprazole, lansoprazole, omeprazole, pantoprazole, and rabeprazole, and found that esomeprazole provided more effective control of gastric acid at steady state than the other PPIs 4.
Recommendations
- Esomeprazole is recommended as the first-line treatment for acid-related disorders due to its superior acid suppression and faster onset of action.
- Patients should be advised to take PPIs 30-60 minutes before meals for optimal effectiveness.
- Regular monitoring by a physician is necessary for patients on long-term PPI therapy to minimize the risk of potential side effects.
