Rabeprazole (Aciphex) is an acid-reducing drug of the proton pump inhibitor group. The active substance blocks the formation of hydrochloric acid at the terminal stage and also reduces the stimulation of secretion, regardless of the type of stimulant.
Bioavailability of the active substance, as well as absorption properties of the drug itself, do not depend on the time of its intake.

Rabeprazole vs Omeprazole
Both drugs belong to the group of proton pump inhibitors. They are used in gastroenterology as part of the complex therapy of acid-dependent pathologies of the digestive tract. However, there are some differences presented in the table.
Name |
Rabeprazole |
Omeprazole |
Indications |
Benign peptic ulcer, Zollinger-Ellison syndrome. In complex therapy with antibacterial drugs for detection of Helicobacter pylori. |
Peptic ulcer disease of the stomach and duodenum (in the acute phase), treatment with Helicobacter pylori (as part of combination therapy). Gastropathy caused by taking non-steroidal anti-inflammatory drugs. |
Side Effects |
Abdominal pain, diarrhea or constipation, flatulence, dry mucous membranes, headache and dizziness, skin rash, peripheral edema. |
Diarrhea or constipation, abdominal pain, nausea, vomiting, flatulence; in rare cases – increased activity of liver enzymes, taste disorders, dry mouth, stomatitis, in patients with previous severe liver disease – hepatitis. |
Course of treatment |
7 days |
In duodenal ulcer – 2-4 weeks, if necessary – 4-5 weeks; in peptic ulcer disease, in reflux esophagitis, in erosive-ulcer gastrointestinal lesions, caused by taking NSAIDs – for 4-8 weeks |
Half-life |
Plasma half-life is about one hour (0.7 to 1.5 hours) |
The elimination half-life is less than 1 hour, and Omeprazole is almost completely eliminated from plasma within 3 to 4 hours. |
The clinical data obtained suggest that Rabeprazole is more effective for the treatment of gastroesophageal reflux disease compared to Omeprazole.
Rabeprazole: Dosage
It is recommended to take Rabeprazole in the morning, on an empty stomach, before a meal. If there is no effect within 3 days, you should inform your doctor.
Treatment of peptic ulcer in acute stage – 20 mg once a day for 4 weeks
Peptic ulcer in the chronic phase – 10 or 20 mg once a day for 6 weeks, if healing is poor, the doctor may extend another 6 weeks.
Reception time and food have no effect on Rabeprazole activity, but it is considered that patients comply better with the prescribed treatment regimen if Rabeprazole is taken in the morning, half an hour before meals (when taken once a day).
Interactions of Rabeprazole
Rabeprazole (Aciphex) reduces the activity of gastric acid secretion. Thus, Rabeprazole interacts with those drugs whose absorption is dependent on gastric pH.
If Rabeprazole sodium and Ketoconazole or Itraconazole are taken simultaneously, the plasma concentrations of the latter may decrease. Therefore, patients using these drugs together with Rabeprazole should consult a physician to determine whether a dose adjustment is necessary.
Concentrations of Rabeprazole may decrease when concomitantly used with antacids.
Low-fat food intake does not affect the absorption of Rabeprazole. Taking the drug with fatty food may delay absorption for 4 hours or more, but the maximum concentration and absorption level remain unchanged.
Rabeprazole and its effects on weight gain
The drug may cause side effects in the form of decreased appetite, which may result in a decrease in body weight. It is important to stick to a gentle diet and doctor's recommendations during treatment.

Rabeprazole and alcohol
When abusing alcohol at the same time as taking Rabeprazole, the side effects may increase.

Regular alcohol abuse during peptic ulcer disease and other diseases for which the drug is prescribed, even in the absence of incompatibility, leads to exacerbations and development of acute conditions.

Anti-secretory action, after oral administration of 20 mg of Rabeprazole (Aciphex), occurs within 1 hour and reaches a maximum after 2-4 hours.
