Pharmacological properties of suppositories with mesalazine

It is an antimicrobial and anti-inflammatory agent.

Pharmacodynamics

Mesalazine refers to antibacterial and anti-inflammatory drugs with localization of action in the intestine.

The active substance inhibits the activity of neutrophilic lipoxygenase and the production of arachidonic acid metabolites.

When using the drug, it is possible to slow down the formation of cytokines in the intestinal mucosa, stop the migration, degranulation, phagocytosis of neutrophils, and the production of immunoglobulins by lymphocytes.

In addition, rectal suppositories have antioxidant properties, thanks to which they are able to bind and destroy oxygen free radicals. They also inhibit the activity of some intestinal bacteria, including Escherichia coli.


Pharmacokinetics

When using suppositories, the active substance is released and distributed in the rectum and the distal third of the colon. The absorption of the drug into the systemic circulation is low and amounts to 10%. The substance is metabolized in the intestinal mucosa and in the liver as an inactive metabolite. Mesalazine and its metabolites are excreted by the kidneys with urine and through the intestines with feces.

Indications for use

The agent under consideration is used in the treatment of inflammatory pathologies of the rectum and distal large intestine:

  • Crohn's disease;
  • ulcerative colitis;
  • proctitis;
  • prosigmoiditis.

Pharmacology

pharmachologic effect- anti-inflammatory.

It inhibits the synthesis of PG, inhibits chemotaxis, degranulation and phagocytosis of neutrophils, the secretion of immunoglobulins by lymphocytes, and has antioxidant properties. Has antibacterial action against coli and some cocci (manifested in the large intestine).

Depending on the dosage form and route of administration, the release of mesalazine occurs in a direct and colon(enemas, suppositories) or terminal small intestine and large intestine (tablets). Tablets (enteric) begin to dissolve in the small intestine (at pH> 6) after 110-170 minutes, completely dissolve after 165-225 minutes after ingestion. During the passage through the intestines, mesalazine is released from the tablets gradually, with 15-30% in the ileum, 60-75% in the large intestine, and only 10% enters the bloodstream. Plasma concentration is low - after a single dose of 250 mg Cmax is 0.5-1.5 μg / ml. In the intestinal mucosa and liver forms N-acetyl-5-aminosalicylic acid. The binding of mesalazine to plasma proteins is about 40%, the metabolite is 75-83%. In breast milk penetrates (in the form of a metabolite) 0.1% of the dose. With rectal administration, 10-30% of the dose is found in daily urine. T 1/2 mesalazine 0.5-1.5 hours, N-acetyl-5-aminosalicylic acid - 5-10 hours.

Effective in the treatment of colitis, ileitis in Crohn's disease, for the prevention of exacerbations of ulcerative colitis in patients with hypersensitivity to sulfasalazine, it is well tolerated (even at a dose of 4.8 g / day comparable to that of placebo). Reduces the risk of recurrence in Crohn's disease, especially in patients with ileitis and a long duration of the disease.

pharmachologic effect

Anti-inflammatory intestinal agent. It has a local anti-inflammatory effect due to inhibition of neutrophilic lipoxygenase and the synthesis of prostaglandins and leukotrienes. It slows down the migration, degranulation, phagocytosis of neutrophils, as well as the secretion of immunoglobulins by lymphocytes. It has an antioxidant effect (due to the ability to bind to free oxygen radicals and destroy them). Mesalazine can also scavenge radicals generated from reactive oxygen compounds. Results from in vitro studies point to a possible role for lipoxygenase inhibition. Also shown is the effect on the content of prostaglandins in the intestinal mucosa.

When taken orally, mesalazine has a predominantly local effect in the intestinal mucosa and submucosal layer, acting from the intestinal lumen. Therefore, it is important that mesalasia is available to areas of inflammation. The ratio of systemic bioavailability and plasma concentration of mesalazine is not significant in terms of therapeutic efficacy, but rather serves as a factor affecting safety.

release active substance in the right place, it helps that Salofalk granules are resistant to gastric juice and are characterized by pH-dependent (due to the coating in the form of Eudragit L) and delayed (due to the matrix structure of the granules) the release of mesalazine.

Pharmacokinetics

Suction and distribution

The release of mesalazine occurs in the terminal small and large intestine. Tablets begin to dissolve in the small intestine after 110-170 minutes and completely dissolve after 165-225 minutes after ingestion. The dissolution rate is not affected by changes in the pH of the medium caused by food intake or other drugs.

The release of mesalazine from the granules begins with a delay of 2-3 hours, Cmax in plasma is reached after about 4-5 hours. The systemic bioavailability of mesalazine after oral administration is approximately 15-25%. Eating slows down absorption by 1-2 hours, but does not change the rate and degree of absorption.

Food intake can slow down the transit of the drug by 1-2 hours, while increasing the values ​​of T lag (time gap after which the mesalazine content is first determined in the blood) and T max, however, due to the small size of the granules, this does not change the rate and degree of absorption.

Eating causes a slight increase in Cmax and AUC.

The pharmacokinetic data of granules and tablets are summarized in the following table (granules: 3×500 mg mesalazine/day, tablets: 3×2 (250 mg) mesalazine/day, steady state, 24 healthy volunteers):

The total amount of mesalazine and N-acetyl-5-aminosalicylic acid (N-Ac-5-ASA) excreted by the kidneys within 24 hours is equivalent to approximately 25-32% of the prescribed dose of Salofalk granules and tablets, respectively. Approximately 30% of this amount is absorbed in the ileocecal zone, and approximately 90% in general in the ileocecal zone and the ascending colon. Thus, approximately 80-90% of the prescribed dose of 5-ASA is present in the descending colon, sigmoid colon, and rectum, where their rate of absorption is low.

The distribution of radioactively labeled 153 Sm (samarium) granules and tablets in the gastrointestinal tract was as follows (mean ± SD (confidence interval)):

The values ​​of serum C max 5-ASA and Ac-5-ASA in the equilibrium state were approximately 1.4 and 1.2 times higher after taking 1 time / day compared with the values ​​observed when taking the drug 3 times / day at the same daily dose. C ss in serum at the end of the dosing period when taken 1 time / day was only slightly lower than when taken 3 times / day (by 0.3 and 0.4 times for 5-ASA and Ac-5-ASA, respectively). When taking the drug 1 time / day, there were no signs of systemic cumulation.

Due to the size of the granules (about 1 mm), transit from the stomach to the small intestine is fast. A combined pharmacoscintigraphic and pharmacokinetic study showed that the drug reaches the ileocecal region in about 3 hours, and the ascending colon in about 4 hours. Total time transit through the colon is about 20 hours. Approximately 80% of the accepted oral dose reaches the colon, sigmoid and rectum.

Plasma protein binding of mesalazine and N-Ac-5-ASA is 43% and 78% (75-83%), respectively.

In breast milk penetrates (in the form of a metabolite) 0.1% of the dose.

Metabolism

Mesalazine is metabolized both presystemically in the intestinal mucosa and systemically in the liver, turning into pharmacologically inactive N-Ac-5-ASA. The nature of acetylation does not depend on the acetylating phenotype of the patient. To a small extent, acetylation can be carried out due to the action of the bacterial microflora of the colon.

breeding

When taking mesalazine at a dose of 500 mg 3 times / day, the total elimination of mesalazine and N-Ac-5-ASA by the kidneys under conditions of saturating concentration was about 25%. Excretion of the unmetabolized portion of mesalazine was less than 1% of the oral dose. T 1/2 in this study was 4.4 hours.

Pharmacokinetics in special clinical situations

With a single oral administration of Salofalk granules at a dose of 20 mg / kg to 13 children with active inflammatory disease large intestine (age from 5.9 to 15.8 years), the pharmacokinetics of the systemic exposure of the drug corresponded to that in adults. Salofalk was safe and well tolerated.

There are no data on the pharmacokinetics of Salofalk in the elderly when it is used, both in tablets and in granules.

Indications

Tablets

- nonspecific ulcerative colitis (NUC);

- Crohn's disease (prevention, treatment of exacerbations).

Granules

- exacerbation of ulcerative colitis of moderate and mild severity;

- maintenance of remission and or long-term therapy of ulcerative colitis.

Dosing regimen

Tablets

The drug is administered orally adults 500 mg 3 times / day. At severe forms diseases the dose may be increased to 3-4 g/day for 8-12 weeks.

For relapse prevention the drug is prescribed 500 mg 3 times / day, if necessary - for several years.

Children weighing up to 40 kg prescribe 1/2 daily dose for adults - 250 mg 3 times / day (tablets of 250 mg should be used), - 500 mg 3 times / day.

For relapse prevention

Tablets should be taken whole, without chewing, after meals and with plenty of water. With distal forms of UC, it is preferable rectal administration drug in the form of rectal suppositories or rectal suspensions.

Granules

Dosing regimen for treatment of exacerbation of ulcerative colitis depends on the clinical need and in each case is individual. Assign 1 sachet of 500-1000 mg of mesalazine 3 times / day or 3 sachets 1 time / day (corresponding to 1.5-3.0 g of mesalazine per day).

For maintaining remission of ulcerative colitis appoint 500 mg (1 pack.) of mesalazine 3 times / day or 3 sachets of 500 mg 1 time / day (corresponding to 1.5 g of mesalazine per day).

Children over 6 years of age and teenagers at exacerbation of the disease, depending on its severity, mesalazine is prescribed at a dose of 30-50 mg / kg of body weight / day with the distribution of the daily dose into 3 doses or 1 dose. For maintaining remission mesalazine is prescribed at a dose of 15-30 mg/ct of body weight/day, while the daily dose can be divided into 2 doses. Children weighing up to 40 kg it is usually recommended to prescribe half the adult dose, children weighing over 40 kg- adult dose.

Salofalk granules should not be chewed. The prescribed dose of Salofalk granules should be taken in the morning, afternoon and evening, or the entire dose once in the morning. Salofalk granules should be put on the tongue and swallowed without chewing, drinking plenty of liquid.

As in the treatment of an exacerbation inflammatory process, and with long-term use in order to maintain remission, the granules must be taken regularly and consistently, which allows you to achieve the required therapeutic effect. Exacerbation of ulcerative colitis usually subsides after 8-12 weeks, after which the dose of mesalazine in most patients can be reduced to 1.5 g / day.

For relapse prevention the drug is prescribed 250 mg 3 times / day, if necessary - for several years.

Overdose

Symptoms: nausea, vomiting, gastralgia, weakness, drowsiness.

Treatment: gastric lavage, the appointment of laxatives, symptomatic therapy. In cases of overdose, if necessary, an infusion of electrolyte solutions is performed (forced diuresis).

drug interaction

With simultaneous use, Salofalk causes an increase in the action of indirect anticoagulants (increased risk of gastrointestinal bleeding).

With the simultaneous use of GCS with Salofalk, it is possible to increase undesirable reactions from the gastric mucosa.

special instructions

Before starting treatment, during and after treatment, it is necessary to conduct a general analysis of blood and urine.

Before starting treatment and during its implementation, it is necessary to determine the parameters of the functional state of the liver (such as ALT or ACT activity) and monitor urine tests (by immersing test strips). Monitoring is usually recommended 14 days after the start of treatment, then another 2-3 times with an interval of 4 weeks. If test results are normal, follow-up tests should be performed every 3 months. If additional symptoms appear, follow-up studies should be performed immediately.

Use with caution in patients with impaired liver function.

When prescribing Salofalk to patients with lung diseases, in particular, bronchial asthma should be closely monitored during treatment.

Patients with a history of indications of adverse reactions when prescribing drugs containing sulfasalazine, they should be carefully monitored during the initial period of treatment with Salofalk.
