Panum

Experience with the use of the drug Panum (pantoprazole) in the treatment of erosive and non-erosive esophagitis

The prevalence of gastroesophageal reflux disease (GERD) is high. The leading symptom of GERD is heartburn. The incidence of heartburn in developed countries in Europe and North America is 7.7–27% (8). According to a population study conducted in Novosibirsk, 48.5% of women and 51.4% of men occasionally experience heartburn; 3.7% of women and 1.2% of men often complain of heartburn. Among adolescents aged 14–17 years, heartburn with a frequency of more than once a month was recorded in 16.9%, more than once a week – in 6.7%, and sour belching was recorded in 8.5% of respondents (9). The results of our own studies showed that the prevalence of GERD in gastroenterological patients according to endoscopy was 27.8%, with non-erosive forms observed in 17.4% of cases, erosive esophagitis in 10.4% (1).

Currently, GERD is divided into an endoscopically negative (non-erosive) - NERD - and a positive form (reflux esophagitis and Barrett's esophagus). The diagnostic standard for NERD is clinical symptoms (primarily heartburn) if they lead to a clinically significant decrease in quality of life.

Today, the most common approach to the treatment of reflux disease is the prescription of proton pump inhibitors (PPIs) in different versions (continuous, course and maintenance, symptomatic). This group of drugs has been used to treat GERD since the 1980s. During clinical use, it was shown that PPIs are superior to H2-blockers in the effectiveness of healing of erosive esophagitis, and maintenance use can significantly reduce the frequency of disease relapses. Today, there are 5 PPIs on the domestic pharmaceutical market: Omeprazole, Lansoprazole, Pantoprazole, Rabeprazole and Esomeprazole.

Selecting a drug from the PPI group poses certain difficulties due to their wide variety and conflicting data on their comparative effectiveness. The differences between them are determined by the speed and duration of the acid-blocking effect, as well as the effect on the metabolism of other drugs that “pass” through the cytochrome P450 system.

Under the influence of PPIs, the proton pump is inactivated, but then its activity returns to its previous level (2). After taking Lansoprazole, the half-life of recovery of acid production is 12.9 hours; Omeprazole and Rabeprazole – 27.5 hours, and Pantoprazole – 45.9 hours (3). The difference in the duration of inhibition is due to differences in the duration of retention of PPI bonds with cysteine residues of ATPase. Omeprazole and other drugs interact with cysteine residues at position 813, Lansoprazole - with cysteine 321, Pantoprazole - with cysteine 822. Cysteine 822 ensures binding stability, therefore, when using Pantoprazole, the secretion of hydrochloric acid is resumed mainly due to the synthesis of ATPase, and not due to the destruction of the chemical connection between the PPI and the proton pump. Thus, the duration of effect of Pantoprazole is longer than that of other PPIs (4).

Metabolism of all PPIs occurs in the liver with the participation of cytochrome P450. Most PPIs inhibit the metabolism of many drugs, such as Diazepam, Phenytoin, Warfarin, β-blockers, Digoxin, Theophylline, Diclofenac, Clarithromycin, Clopidogrel, etc. (5). If it is necessary to take several drugs in combination, it is advisable to use PPIs with minimal effect on microsomal enzymes of hepatocytes. Pantoprazole is superior to other PPIs in this regard, as demonstrated in a study by DN Juurlink et al (6). They conducted a population-based case-control cohort study over a 5-year period among patients aged 66 years or older who started clopidogrel after hospital treatment for acute myocardial infarction. The study included patients who were readmitted to the hospital with acute myocardial infarction within 90 days of discharge.

Among 13,636 patients receiving clopidogrel after acute myocardial infarction, 734 cases with rehospitalization with myocardial infarction and 2057 control cases were identified. In an expanded multivariate analysis, there was an association between current use of proton pump inhibitors and an increased risk of recurrent infarction (adjusted odds ratio (OR) 1.27, 95% confidence interval (CI) 1.03–1.57). In the stratification analysis, Pantoprazole, which does not inhibit cytochrome P450 2C19 was not associated with readmission for myocardial infarction (adjusted OR 1.02, 95% CI 0.70–1.47).

Among patients receiving clopidogrel after acute myocardial infarction, concomitant therapy with proton pump inhibitors other than pantoprazole was associated with a decrease in the beneficial effects of clopidogrel and an increased risk of recurrent infarction (6).

The experience of using Pantoprazole in our country is currently limited. For this reason, we assessed the effectiveness and safety of a course of therapy with Panum (Pantoprazole) (Unique Pharmaceutical Laboratories, Department, India) in patients with erosive and non-erosive forms of GERD for 8 weeks and maintenance therapy for 8 weeks.

Materials and methods

The effectiveness of a course of therapy with Panum (Pantoprazole) 40 mg per day was assessed based on the number of patients with complete healing of erosions and complete relief of heartburn by the 8th week of therapy. The effectiveness of maintenance therapy with Panum (Pantoprazole) 40 mg every other day for non-erosive and erosive reflux disease for 8 weeks was assessed by the number of patients who maintained clinical and endoscopic remission. The safety assessment of the drug was based on the registration of adverse events and side effects.

Additional objectives of the study were: to assess the healing of erosive esophagitis by the 4th week of treatment; assessment of serum gastrin levels before and after 8 weeks of course treatment; study of the level of quality of life according to the visual analogue scale and the SF 36 questionnaire before and after a course and maintenance treatment.

The study included patients with GERD grades 0–4 according to the Savary–Miller classification, who had heartburn of varying severity before treatment and met the inclusion and exclusion criteria.

Statistical processing of the results was carried out using statistical analysis programs Statistica 6. Descriptive statistics are presented in the form of average values and their standard deviation (M±SD). Comparisons of average values were carried out using the Student's t-test; differences at the p level were taken as statistically significant

If all inclusion and exclusion criteria were met, the patient entered the treatment period. At the second visit (day 1 of treatment), the patient was given the drug for 28 days of treatment and instructions for its use. During the entire treatment period, patients recorded in an individual diary the presence and severity of symptoms (heartburn and acid regurgitation) during the day and night, as well as the use of additional medications (antacids) if heartburn persisted. At all follow-up visits (28, 56, 84 and 112 days), a physical examination and assessment of the severity of symptoms, registration of adverse events and side effects, as well as endoscopy were performed to assess the degree of inflammatory changes in the esophageal mucosa. Quality of life assessment according to VAS and SF-36 questionnaire was carried out on days 56 and 112 of treatment.

Research results

30 HP-negative patients (20 men, 10 women) were accepted for the study. Average age 45.6±2.8 years. The degree of erosive esophagitis was determined according to the Savary–Miller classification. Depending on the degree of GERD, patients were distributed as follows: 0th degree - 5, 1st degree - 15, 2nd degree - 5, 3rd degree - 2, 4th degree - 3 people.

Evaluation of effectiveness in the treatment of grade 0–4 erosive esophagitis based on the number of patients with complete healing of erosions by the 4th and 8th weeks of therapy

The results of endoscopy data at the 4th and 8th week of treatment for patients with erosive esophagitis are presented in Table 1.

When treating 25 patients with erosive esophagitis, 2 patients dropped out due to the development of side effects. Thus, the analysis of the results was carried out: – in a group of 25 patients according to the “intention to treat” (ITT – intent-to-treat); – in a group of 23 patients who completed this part of the study “per protocol” (PP – per protocol).

As can be seen from the presented data, in the ITT analysis, the healing rate by the 4th and 8th weeks of therapy was 84% and 88%, respectively. When analyzing PP, the effectiveness of therapy according to endoscopy by the 4th and 8th weeks of treatment was 91.3% and 95.6%, respectively. Healing of erosions could not be achieved in 1 patient with grade 4 erosive esophagitis.

Evaluation of effectiveness in the treatment of GERD based on the number of patients with complete relief of heartburn by the 8th week of therapy

The results of studying the number of patients with complete relief of heartburn by the 8th week of treatment are presented in Table 2.

In the ITT analysis, complete relief of heartburn out of 30 patients with erosive and non-erosive forms of GERD was achieved in 86.6%. When analyzing RR, heartburn was completely relieved in 92.9% of cases, in 2 patients mild heartburn remained: in 1 patient with grade 4 erosive esophagitis and persistence of erosions by the 8th week of course therapy and in 1 patient with complete healing of erosions by the end of the course therapy, according to the individual diary, heartburn also persisted.

Assessment of serum gastrin levels before and after 8 weeks of course treatment

Gastrin concentrations were determined using an automatic chemiluminescence immunoassay analyzer Immulite2000 (DPC, USA). The method allows you to determine with high accuracy the level of gastrin 17, but not other molecular forms of gastrin (big and big-big gastrin). The results of determining the level of serum gastrin 17 before and after 8 weeks of therapy with Panum are presented in Table 3.

The differences were significant, Student's test was 3.5; p = 0.001.

Thus, treatment for 8 weeks led to an increase in the level of serum gastrin 17 by more than 2 times. These data indirectly reflect the effective acid suppression under the influence of therapy with Panum.

Evaluation of the effectiveness of course therapy based on the results of studying VAS data and the SF-36 questionnaire

The dynamics of VAS data are presented in Table 4.

The presented data indicate a significant increase in the quality of life according to VAS data already by the 4th week of treatment and its improvement by the 8th week of therapy. The results of studying the data from the SF-36 questionnaire are presented in Table 5.

The 36 items of the questionnaire are grouped into eight scales: physical functioning, role functioning, bodily pain, general health, vitality, social functioning, emotional state and mental health. Scores on each scale range between 0 and 100, with 100 representing complete health, such that a higher score indicates a higher level of QoL.

After 8 weeks of therapy with Panum, there was a significant improvement in physical functioning; role functioning due to physical condition; pain intensity; vital activity; social functioning; role functioning due to emotional state; mental health. The consequence of this was a significant improvement in the physical (Physical health - PH) and psychological (Mental Health - MH) components of health (Table 5).

Evaluation of the effectiveness of maintenance therapy for non-erosive and erosive reflux disease based on the number of patients with complete relief of heartburn by the 4th and 8th weeks of maintenance therapy

By the 4th week of maintenance therapy, recurrence of heartburn was noted by 4 (14.8%) patients out of 27 patients who continued the study. Relapse occurred in patients with erosive esophagitis. In two patients, heartburn was mild, not daily, and amounted to 4 and 5 points according to the calculated indicator. Thus, by the 4th week of maintenance therapy, its effectiveness was 85.2%.

The final assessment of effectiveness by the 8th week of maintenance treatment was as follows: relapse of symptoms was observed in 4 patients (14.8%), relapse of erosive esophagitis was observed in 5 patients (18.5%). The overall effectiveness of 8-week maintenance therapy, taking into account both the clinical and endoscopic picture, was 77.8%.

Evaluation of the effectiveness of maintenance therapy based on the results of studying data from the VAS and the SF-36 questionnaire.

The dynamics of VAS data are presented in Table 6.

The presented data indicate that a significant increase in the quality of life according to VAS obtained after a course of therapy was maintained during maintenance treatment. The results of studying the data from the SF-36 questionnaire are presented in Table 7.

Positive changes in quality of life according to the SF-36 questionnaire obtained after a course of therapy persisted after 8 weeks of maintenance treatment.

The safety assessment of the drug Panum (Pantoprazole) at a dose of 40 mg per day is based on the registration of adverse events and side effects in all treated patients.

The safety assessment was the frequency of adverse events assessed according to the following criteria: severity, severity, relationship between the side effect and the study drug, outcome and measures taken.

No serious adverse events were noted during the study. Side effects in the form of abdominal pain were observed in 3 patients; in 2 cases the drug was discontinued. In one patient, the pain was mild and went away on its own after reducing the dose when transferring him to maintenance treatment.

Conclusion

A course of treatment with Panum at a dose of 40 mg per day in patients with degrees 1–4 erosive esophagitis was highly effective: in the ITT analysis, the healing rate by weeks 4 and 8 of therapy was 84% and 88%, respectively. When analyzing the RR, the effectiveness of therapy according to endoscopy at 4 and 8 weeks of treatment was 91.3% and 95.6%, respectively. Healing of erosions could not be achieved only in 1 patient with grade 4 erosive esophagitis.

An assessment of the clinical effectiveness of the drug Panum showed that the drug effectively relieves heartburn: in the ITT analysis, complete relief of heartburn out of 30 patients with erosive and non-erosive forms of GERD was achieved in 86.6%. When analyzing the RR, heartburn was completely relieved in 92.9% of cases, in 2 patients mild heartburn persisted.

A course of treatment with Panum led to a significant increase in the quality of life according to VAS data already by the 4th week of treatment and its improvement by the 8th week of therapy. A significant increase in quality of life according to VAS, obtained after a course of therapy, persisted during maintenance treatment.

After a course of therapy with Panum, there was a significant improvement in the following indicators of the SF 36 questionnaire: physical functioning; role functioning due to physical condition; pain intensity; vital activity; social functioning; role functioning due to emotional state; mental health. The consequence of this was a significant improvement in the physical and psychological components of health. Positive changes in quality of life according to the SF-36 questionnaire obtained after a course of therapy persisted after 8 weeks of maintenance treatment.

Evaluation of the effectiveness of maintenance treatment with Panum at a dose of 40 mg every other day for 8 weeks showed that relapse of symptoms was observed in 4 patients (14.8%), relapse of erosive esophagitis was observed in 5 patients (18.5%). The overall effectiveness of 8-week maintenance therapy, taking into account both the clinical and endoscopic picture, was 77.8%. Thus, maintenance treatment at the indicated dose was quite effective.

Treatment for 8 weeks led to a significant increase in the level of serum gastrin 17 by more than 2 times, which indirectly reflects the effective acid suppression during treatment with this drug.

The results of this study confirm the high clinical effectiveness of Pantoprazole in the treatment of patients with various forms of GERD. A recent population-based study showed that the use of Pantoprazole at a dose of 40 mg per day was significantly more likely to lead to a decrease in complaints after 28 days of treatment than the use of Esomeprazole at the same dose (7). Additional advantages of Pantoprazole are: long-term suppression of acid production, which makes it safe to skip the next dose of the drug; low affinity for cytochrome P450, allowing the necessary concomitant therapy to be carried out effectively and safely.

* if HP was detected and the patient consented, a course of eradication therapy was carried out for 2 weeks, followed by a control study for HP 4 weeks after the end of the eradication course; If eradication therapy was effective, the patient was accepted into the study.

Panum, 20 mg, enteric film-coated tablets, 28 pcs.

Before starting treatment with Panum®, the possibility of malignancy should be excluded, since the drug may mask symptoms and delay the correct diagnosis.

Patients should consult their physician if they are undergoing an endoscopy or urea breath test.

Patients should consult a doctor if the following occur:

- unintentional weight loss, anemia, gastrointestinal bleeding, difficulty swallowing, persistent vomiting or vomiting blood. In these cases, taking the drug may partially relieve symptoms and delay correct diagnosis;

- previous surgery on the gastrointestinal tract or gastric ulcer;

- continuous symptomatic treatment of dyspepsia and heartburn for 4 weeks or more;

- liver diseases, including jaundice and liver failure;

- other serious diseases that worsen general health.

Patients over the age of 55 who have new or recently changed symptoms should consult a doctor.

Patients should not expect immediate relief from symptoms of illness. Symptom relief may be possible after approximately one day of taking pantoprazole, but it should also be taken into account that it may take approximately 7 days for heartburn to completely resolve.

When taking medications that reduce the acidity of gastric juice, the risk of gastrointestinal infections caused by bacteria of the genus Salmonella spp., Campylobacter spp. slightly increases. or C. difficile.

When treated with proton pump inhibitors, the development of subacute cutaneous lupus erythematosus (SCLE) is very rarely observed. If skin lesions occur, especially in sun-exposed areas, or if there is concomitant arthralgia, the patient should seek immediate medical attention and the physician should evaluate the need to discontinue treatment with Panum®. The occurrence of PCLE after previous treatment with a proton pump inhibitor may increase the risk of developing PCLE when treated with other proton pump inhibitors.

When conducting laboratory tests, it is necessary to take into account that increased levels of CgA in the blood serum may distort the results of diagnostic studies to identify neuroendocrine tumors. In this regard, the use of Panum® should be discontinued at least 5 days before the CgA content study. If CgA and gastrin levels have not returned to normal values after the first determination, the study should be repeated 14 days after stopping the proton pump inhibitor.

The drug is intended for short-term use (up to 4 weeks).

With long-term use of the drug, additional risks may arise, and it is necessary to consult a doctor to prescribe the drug, followed by regular medical supervision.

The following additional risks are considered significant with long-term use of the drug.

Effect on the absorption of Vitamin B12

Pantoprazole, like all proton pump inhibitors, can reduce the absorption of vitamin B12 (cyanocobalamin) as a result of hypo- or achlorhydria. This should be taken into account in patients with reduced body reserves or risk factors for reduced absorption of vitamin B12 during long-term therapy or in the presence of corresponding clinical symptoms.

Effect on bone fractures

Proton pump inhibitors, especially at high doses and during long-term therapy (>1 year), may slightly increase the risk of hip, wrist, and spine fractures, primarily in older adults or those with other known risk factors. Observations have shown that proton pump inhibitors may increase the overall risk of fractures by 10-40%. This increase may be due in part to other risk factors.

Patients at risk of developing osteoporosis should be treated in accordance with current clinical guidelines and should have an adequate intake of vitamin D and calcium.

Hypomagnesemia

Patients taking proton pump inhibitors (PPIs), including pantoprazole, for at least three months and, in most cases, for a year, experienced severe hypomagnesemia. In this case, it is possible to develop severe manifestations of hypomagnesemia, such as fatigue, tetany, delirium, convulsions, dizziness and ventricular arrhythmia, they can begin unnoticed and be missed. In most patients with such disorders, hypomagnesemia was corrected after magnesium replacement therapy and discontinuation of PPIs.

In patients undergoing long-term treatment or patients taking PPIs concomitantly with digoxin or other drugs that may cause hypomagnesemia (eg, diuretics), serum magnesium levels should be tested before initiating PPI treatment and monitored periodically during treatment. .

Panum ®

(lat.
Panum ®
) - antiulcer drug, proton pump inhibitor.

Composition and dosage forms of Panum

The active ingredient of Panum is pantoprazole (lat. pantoprazole
). Panum is available in two dosage forms:

in the form of enteric-coated tablets containing pantoprazole sodium sesquihydrate 45.1 mg, equivalent to 40 mg pantoprazole

excipients of Panum tablets:
crospovidone, calcium stearate, mannitol, povidone, anhydrous sodium carbonate, sodium hydroxide, simethicone emulsion (30%), Opadry YS-1R-7006 transparent dye (hypromellose 5cP, macrogol 400, macrogol 6000), Opadry acrylic dye yellow 93O92052 (methacrylic acid copolymer, type C), talc, titanium dioxide, triethyl citrate, colloidal silicon dioxide, sodium bicarbonate, iron oxide yellow, sodium lauryl sulfate and

in the form of a lyophilisate for the preparation of a solution for intravenous administration, one bottle contains 40 mg of pantoprazole

Indications for use of Panum

Panum is indicated for gastric or duodenal ulcers in the acute phase, reflux esophagitis, Zollinger-Ellison syndrome, Helicobacter pylori
(only in combination with antibacterial drugs). Panum (pantoprazole) is preferred over other proton pump inhibitors if the patient must take drugs such as clopidogrel concomitantly with a PPI or take multiple drugs at the same time when drug interactions are difficult to determine.

Contraindications to the use of Panum

dyspepsia of neurotic origin
malignant diseases of the gastrointestinal tract
hypersensitivity to pantoprazole and other components of the drug

Doses and order of use of Panum

Film-coated tablets do not break, are taken orally whole, do not chew, and are washed down with a small amount of liquid.
For peptic ulcer of the stomach and duodenum, gastroesophageal reflux disease, the daily dose is 40 mg once, it is possible to increase the daily dose to 80 mg. The duration of therapy for duodenal ulcer is 2 weeks, for gastric ulcer and gastroesophageal reflux disease - 4 weeks. In some cases, this period is doubled, respectively, to 4 or 8 weeks.

When eradicating Helicobacter pylori

Panum is used in combination with antibiotics as part of the so-called.
eradication “schemes”: for the treatment of Helicobacter-associated gastric or duodenal ulcers - 40 mg of Panum plus 1000 mg of amoxicillin plus 500 mg of clarithromycin, all 2 times a day. Instead of amoxicillin, metronidazole at a dose of 500 mg can be prescribed. The duration of the course is one or two weeks. Other eradication schemes are allowed ( see “Standards for diagnosis and treatment of acid-dependent and Helicobacter pylori-associated diseases (4th Moscow Agreement)”
).

Side effects of Panum

from the digestive system: diarrhea; rarely - nausea, pain in the upper abdomen, flatulence
from the central nervous system: headache; rarely - weakness, dizziness; in isolated cases - initial manifestations of depressive states, visual impairment
dermatological reactions: rarely - rash, itching
others: weakness, dizziness; in isolated cases - swelling, increased body temperature

Use of Panuma during pregnancy and lactation

If it is necessary to use Panum during pregnancy, it is necessary to evaluate the expected benefit to the mother and the potential risk to the fetus.
FDA fetal risk category is B.

If it is necessary to use Panum during lactation, the issue of stopping breastfeeding should be decided. Experimental studies have shown that pantoprazole is excreted in breast milk.

Special instructions when using Panum

Before starting therapy with Panum, the possibility of a malignant neoplasm in the stomach and esophagus should be excluded, since the use of pantoprazole reduces the severity of symptoms and may delay the establishment of the correct diagnosis.
The diagnosis of reflux esophagitis requires mandatory endoscopic confirmation. When using Panum in patients with impaired liver function, the activity of liver enzymes in the blood plasma should be regularly monitored and Panum should be discontinued if it increases.

Interaction of Panum with other drugs

When used concomitantly, Panum may alter the absorption of drugs whose absorption depends on gastric acidity (ketoconazole).
Due to the fact that pantoprazole is metabolized in the liver by the cytochrome P450 system, the possibility of drug interaction between pantoprazole and drugs metabolized by the same cytochrome cannot be excluded.

Study of the effectiveness of Panum in patients with GERD

At the Central Research Institute of Gastroenterology (Moscow), a study was conducted on the effectiveness of treatment with Panum in patients with GERD. All patients with a confirmed diagnosis of GERD were offered the following treatment regimen: patients took Panum 40 mg once a day in the morning, 30 minutes before breakfast. If after a week the symptoms did not improve, then daily pH measurements were performed, which assessed the level of decrease in acidity in the stomach. If the reduction was not enough, then the dose of Panum was doubled. Taking into account the dose adjustment, 100% scarring and epithelization of defects in the esophageal mucosa were achieved. For the treatment algorithm, see the figure below (Masharova A.A. et al.):
