"What are the Primary Ingredient Categories Found in Commonly Prescribed Stomach Medications?"

With the improvement of people's material living standards, many individuals have developed poor eating habits, leading to various gastric diseases. Severe gastric conditions often require medication, often in the form of chronic treatments that necessitate long-term use of drugs for regulation. This sustained medication has caused many patients to inquire about the primary ingredients of stomach medications and their potential adverse health effects. So, what are the main ingredients found in commonly used stomach medications? Let's take a look.

What Are the Main Ingredient Types in Commonly Used Stomach Medications?

Antacids; Bismuth Potassium Citrate; H2 Receptor Antagonists; Proton Pump Inhibitors; Magnesium Hydroxide; Antibiotics. Other ingredients include Bismuth Subnitrate, Magnesium Carbonate, Sodium Bicarbonate, Dried Aluminum Hydroxide Gel, Magnesium Trisilicate, and Belladonna Extract.

What Are Some Common Stomach Medications?

1. Antacids (Representative Drugs: Aluminum Hydroxide, Magnesium Oxide, Magnesium Trisilicate, etc.)

Antacids are typically weak alkaline substances that neutralize stomach acid upon oral administration, reducing the acidity of gastric contents and mitigating irritation to the stomach and duodenum, thereby alleviating pain and promoting healing. Some drugs, while consuming excessive stomach acid, can also form gelatinous compounds that adhere to the inner wall of the stomach, providing a certain level of protection to the gastric mucosa. However, it's crucial to consider the potential side effects of antacids. For instance, patients with gastric ulcers should avoid medications that produce carbon dioxide to prevent risks like gastric perforation due to bloating. Additionally, aluminum hydroxide may cause constipation, while magnesium trisilicate may lead to silica urolithiasis. When recommending medications, consider synergistic effects and risk reduction for optimal combinations.

2. Acid Suppressants (Representative Drugs: Omeprazole, Esomeprazole, Cimetidine, etc.)

Unlike antacids, acid suppressants work by inhibiting gastric acid secretion, thereby lowering acidity and addressing conditions like peptic ulcers and reflux esophagitis. Drugs like Cimetidine and Ranitidine do not significantly irritate the gastric mucosa and their absorption is largely unaffected by gastric contents. Proton Pump Inhibitors (PPIs) such as Omeprazole and Lansoprazole have stronger acid-suppressing effects, with longer-lasting and more pronounced therapeutic outcomes, but their absorption and utilization can be more susceptible to gastric contents. Consequently, H2-receptor antagonists like Cimetidine are often taken after meals or before bedtime, while PPIs are better suited for morning or fasting use.

3. Anti-Helicobacter Pylori Drugs (Representative Drugs: Amoxicillin, Metronidazole, etc.)

Helicobacter pylori is often the causative agent of chronic gastritis, necessitating anti-Helicobacter pylori therapy in diagnosed cases. This treatment involves combining antibiotics with colloidal bismuth or PPIs, though antibiotic usage remains crucial. As Helicobacter pylori is a spiral-shaped Gram-negative, microaerophilic bacterium, a combination of Metronidazole and Amoxicillin, along with Bismuth Potassium Citrate or Omeprazole, is often used to eradicate the bacteria and protect the gastric mucosa.

4. Prokinetics (Representative Drugs: Metoclopramide, Domperidone, Mosapride, etc.)

Prokinetics are indicated for conditions like delayed gastric emptying, dyspepsia, nausea, vomiting, or even intestinal obstruction due to insufficient gastrointestinal motility. They are thus effective in addressing gastroparesis, constipation, reflux esophagitis, and functional dyspepsia. Prokinetics are typically taken half an hour before meals, ensuring peak efficacy during mealtime to stimulate gastrointestinal motility. However, note that anticholinergic drugs like Atropine and Belladonna Extract have opposing effects on the gastrointestinal tract and should not be used concurrently with prokinetics.

5. Gastric Mucosal Protective Agents (Representative Drugs: Bismuth Potassium Citrate, Sucralfate, etc.)

Gastric mucosal protective agents prevent and treat gastric mucosal damage, promote tissue repair, and aid in ulcer healing. These agents vary widely, with some having both antacid and Helicobacter pylori-killing properties, like Alkaline Bismuth Carbonate and Bismuth Potassium Citrate/Colloidal Bismuth Pectin. The efficacy of these drugs hinges on their intragastric concentration and contact time with the gastric mucosa.
