Tablets for gastritis: what is prescribed?

Gastritis is an inflammation of the gastric mucosa with various causes: Helicobacter pylori infection, long-term use of nonsteroidal anti-inflammatory drugs, alcohol, stressful hospitalizations, and autoimmune mechanisms. "Gastritis pills" aren't a single magic pill, but a set of strategies: eliminating the cause, protecting the mucosa, and controlling acidity until healing occurs. If Helicobacter pylori is suspected, it's important not just to "suppress" symptoms, but to undergo testing and eradication. [1]

Acid-suppressant drugs help most patients survive the acute phase, but their role varies depending on the scenario: for Helicobacter pylori-associated gastritis, the key treatment is a combination antibacterial regimen plus acid suppression; for nonsteroidal anti-inflammatory drug-associated gastritis, drug discontinuation or replacement and gastroprotection; for autoimmune gastritis, correction of deficiencies and observation. Doses and duration of treatment are selected individually. [2]

An important current trend is the careful prescribing of proton pump inhibitors: they work well, but they must be used at the correct dose and for no longer than necessary. Professional societies emphasize the principles of the "minimum effective dose" and scheduled therapy reviews when symptoms are controlled. [3]

Before self-medication, it's advisable to discuss your symptoms with a doctor: pain on the left side under the ribs, burning, nausea, bloating, intolerance to fatty foods, and hunger pains are all reasons for evaluation. Alarming signs (weight loss, vomiting blood, black stool, anemia, dysphagia) require urgent diagnosis. Medications in these situations are prescribed only after an examination. [4]

Table 1. What we treat with tablets for gastritis

Scenario	The main goal	Basic strategy
Helicobacter pylori	Destroy bacteria and heal the mucous membrane	Combination antibacterial regimen + acid suppression
Nonsteroidal anti-inflammatory drugs	Stop damage to the mucous membrane	Review of pain relief + gastroprotection
Stress factors in hospital	Prevention and healing of erosions	Acid suppression as indicated
Autoimmune gastritis	Correction of deficiencies	Vitamin B12, observation, individually

Acid suppression: proton pump inhibitors and H2 receptor blockers

Proton pump inhibitors remain the most potent agents for reducing acidity and relieving symptoms. They accelerate the healing of erosions, reduce pain and heartburn, and promote mucosal restoration. For gastritis, especially erosive gastritis, they are used in courses, usually 2-8 weeks, followed by switching to "on-demand" or discontinuing treatment. [5]

H2-histamine receptor blockers are less potent than proton pump inhibitors, but may be useful for nighttime symptoms, mild exacerbations, and as a step-down when discontinuing stronger medications. It is important to remember the long-standing withdrawal of ranitidine from the market due to impurities and to choose modern alternatives. [6]

New potassium-competitive acid blockers, such as vonoprazan, provide rapid and sustained acid suppression. They are already used in Helicobacter pylori eradication regimens and for the treatment of erosive esophagitis; their place in widespread clinical practice is being discussed, particularly when standard therapy fails. The decision to use them is made by a physician, taking into account availability and indications. [7]

When using acid suppressants long-term, guidelines recommend reassessing the need for continuation every few months, returning to the minimum effective dose and making lifestyle adjustments. This reduces medication burden without losing symptom control. [8]

Table 2. Acid Suppression: Dosage Guidelines

Class	Examples	Typical doses in adults	Notes
Proton pump inhibitors	omeprazole, pantoprazole, esomeprazole	20-40 mg per day	2-8 weeks with evaluation of the effect
H2 receptor blockers	famotidine, cimetidine	equivalent to 20-40 mg famotidine per day	"night" supplementation is possible
Potassium-competitive acid blockers	vonoprazan	10-20 mg 1-2 times a day	as indicated, more often in Helicobacter pylori regimens

Gastroprotectors and mucosal "defenders": sucralfate, rebamipide, alginates, bismuth

Sucralfate forms a protective film on the surface of erosions, binds bile acids and pepsin, and reduces the aggressiveness of gastric contents. It is prescribed in courses for erosive changes and drug-induced gastric lesions, sometimes in combination with acid suppression. The drug does not eliminate the underlying cause, but it promotes mucosal healing. [9]

Rebamipide stimulates mucosal prostaglandin synthesis and increases epithelial resistance to damage. Studies have shown a reduction in endoscopic signs of inflammation, including those seen with nonsteroidal anti-inflammatory drugs; it is considered an adjunct to standard therapy in selected patients. [10]

Alginates physically form a "raft" on the surface of the stomach contents, reducing acid-mucosal contact and alleviating heartburn and regurgitation. They are useful as a symptomatic adjunct to proton pump inhibitors, including when discontinuing strong therapy to avoid rebound symptoms. [11]

Bismuth salts have mild antimicrobial and cytoprotective effects and are included in classic quadruple therapies for Helicobacter pylori. They are used less frequently in "pure" gastritis without Helicobacter pylori, but they are important as part of eradication regimens, especially in the presence of antibiotic resistance. [12]

Table 3. Mucoprotectors and additional agents

Means	How it helps	When appropriate
Sucralfate	protective film on erosions, binds pepsin	erosive gastritis, drug-induced damage
Rebamipide	enhances protective prostaglandins	adjunct to therapy for persistent inflammation
Alginates	mechanical barrier, heartburn control	as an adjunct to therapy when discontinuing acid suppressants
Bismuth	cytoprotector and part of anti-Helicobacter regimens	as part of quadruple therapy

Helicobacter pylori: When "gastritis pills" are eradication regimens

If tests confirm Helicobacter pylori, four-drug regimens containing bismuth for 14 days have become the standard: a proton pump inhibitor, bismuth, tetracycline, and metronidazole at optimized doses. This approach is recommended as a first-line treatment when antibiotic susceptibility is unknown and as a rescue regimen after treatment failure. [13]

Clarithromycin-containing triple regimens are no longer considered an empirical choice due to widespread resistance: they can only be prescribed if the bacteria are confirmed to be susceptible. Otherwise, the risk of failure is high. [14]

Rifabutin-based regimens and vonoprazan-based regimens have emerged as alternatives. The potassium-competitive acid blocker maintains stable acid suppression, increasing the chances of success with combination antibacterial therapy; dual therapy with amoxicillin and triple therapy are available. The choice depends on the region, antibiotic history, and tolerability. [15]

After the course, cure must be confirmed no sooner than 4 weeks later: a urea breath test or Helicobacter pylori antigen test in the stool. Acid suppressants should be discontinued for 2 weeks prior to the test to avoid false negative results. Repeated failures require a regimen adjusted according to the antibiogram. [16]

Table 4. Examples of modern 14-day Helicobacter pylori eradication regimens

Scheme	Compound	When choosing
Quadruple therapy with bismuth	proton pump inhibitor + bismuth + tetracycline + metronidazole	default choice when sensitivity is unknown
Double based on vonoprazan	vonoprazan + amoxicillin	alternative without clarithromycin
Triple based on vonoprazan	vonoprazan + amoxicillin + clarithromycin	only with expected sensitivity
Triple with rifabutin	proton pump inhibitor + amoxicillin + rifabutin	an alternative in case of failures and limitations of other antibiotics
[17]

Nonsteroidal Anti-Inflammatory Drug-Associated Gastritis: How to Protect Your Stomach

The first step is to reassess pain management: identify the minimum effective dose, explore alternatives, and add gastroprotective agents. Proton pump inhibitors are generally more effective than H2 receptor blockers in preventing and treating ulcers while taking nonsteroidal anti-inflammatory drugs, but the choice is made on an individual basis, taking into account the associated risks. [18]

Sucralfate and rebamipide are used as adjunctive agents to protect the mucosa, especially in cases of erosions and when continued anesthesia is necessary. They do not replace the primary strategy but can improve comfort and accelerate healing. [19]

For patients at high risk of complications (old age, anticoagulants, glucocorticoids, ulcer history), gastroprotection is considered proactively, rather than based on symptoms. This reduces the risk of bleeding and hospitalization. [20]

It's important to remember non-drug measures: abstaining from alcohol during treatment, eating small meals with an emphasis on gentle foods, weight control, and sleeping with the head of the bed elevated if nighttime symptoms occur. These measures do not replace medications, but they enhance their effectiveness and help you return to normal life more quickly. [21]

Table 5. Gastroprotective profile of nonsteroidal anti-inflammatory drugs

Situation	What to do	How to help the mucous membrane
Need painkillers regularly	minimum effective dose, evaluation of alternatives	proton pump inhibitor course
High risk of complications	prevention in advance	proton pump inhibitor, individual supplements
There are already erosions	temporarily reduce aggression	add sucralfate, consider rebamipide
Severe nighttime symptoms	targeted assistance	add an H2 receptor blocker at night

Safety, withdrawal, and drug interactions

Current guidelines recommend not to prolong proton pump inhibitor use unless necessary: as symptoms improve, switch to the minimum maintenance dose or discontinue the drug completely based on symptomatic control. When discontinuing, short-term use of alginates is acceptable to alleviate heartburn rebound. [22]

When choosing an H2 receptor blocker, safety is a key consideration: ranitidine was removed from the market due to nitrosamine contamination, so alternatives such as famotidine are often considered. If in doubt, it's best to discuss the option with a specialist. [23]

Interactions are important for all acid suppressants: they can alter the absorption of certain drugs and nutrients. During long-term treatment, the physician assesses iron and vitamin B12 deficiencies, especially in patients with underlying conditions. An individualized monitoring plan prevents the accumulation of risks. [24]

When eradicating Helicobacter pylori, the regimen and timing of treatment must be strictly adhered to; otherwise, effectiveness decreases and resistance increases. Repeated "incomplete" courses do more harm than good; if unsuccessful, a change in strategy is required, not "the same course again." [25]

Table 6. When to reconsider therapy

Situation	Action
Symptoms went away after 4-8 weeks	attempt to reduce the dose or discontinue under supervision
The symptoms have returned	return to the minimum effective dose, add alginate briefly
Long courses without revision	visit to the doctor, assessment of necessity and risks
Helicobacter pylori eradication is complete	control test after 4-8 weeks with discontinuation of the acid suppressant in advance

Practical schemes: what it looks like in reality

For "regular" erosive gastritis without Helicobacter pylori, the doctor often begins with a course of a proton pump inhibitor at a standard dose for 4-8 weeks, adding alginate or an H2 receptor blocker at night as needed. The dose is then reduced or discontinued, while non-drug measures are continued. This helps control pain and burning and gives the mucosa time to recover. [26]

If the test is positive for Helicobacter pylori, eradication is the priority: a four-drug regimen with bismuth for 14 days, or a modern alternative as indicated. After the course, a control test and, if necessary, a treatment adjustment are recommended. Symptomatic "gastritis pills" are only a supplement during this period. [27]

For gastritis associated with nonsteroidal anti-inflammatory drugs, the emphasis is on reassessing pain management and protecting the mucosa: a proton pump inhibitor course, sucralfate for erosions, then gradually withdrawing once the condition stabilizes. In high-risk patients, prophylaxis begins early. [28]

If autoimmune gastritis is suspected, the doctor assesses vitamin B12 and iron levels, corrects deficiencies, and plans follow-up. Acid-suppressive therapy in this group is prescribed individually, based on symptoms and associated conditions. [29]

FAQ: Simple Answers to Complex Questions

Is it possible to treat gastritis solely with "gastroprotective" medications without reducing acidity?
Sometimes yes, if the inflammation is superficial and the underlying cause has been eliminated. However, with erosions and severe symptoms, acid suppressants accelerate healing and relieve pain; the choice is made by a doctor after an examination. [30]

Should you start taking "Helicobacter pylori pills" without testing "just in case"?
No. The correct approach is to first confirm the infection, then complete the full eradication regimen, and then confirm the cure with a follow-up test. [31]

Why do doctors so insistently recommend a four-drug regimen with bismuth for 14 days?
Because it has demonstrated high efficacy in conditions of widespread clarithromycin resistance and is recommended as the default choice when susceptibility is unknown. [32]

Is it dangerous to take proton pump inhibitors long-term?
The risks of long-term and uncontrolled use are debated, so the principles of "minimum effective dose" and regular reassessment apply. With proper management, the benefits usually outweigh the risks. [33]
