INSTRUCTION FOR THE SPECIALIST.

Description of the drug approved by the manufacturer for the printed edition of 2014.

PHARMACHOLOGIC EFFECT

The drug for rectal administration.
Has a local anti-inflammatory effect due to inhibition of neutrophilic lipoxygenase and the synthesis of prostaglandins and leukotrienes. Slows migration, degranulation, phagocytosis of neutrophils, as well as secretion of immunoglobulins by lymphocytes.
It has antibacterial action against Escherichia coli and some cocci.

It has an antioxidant effect due to the ability to bind to free oxygen radicals and destroy them.

It is important to consider that mesalazine has only a local anti-inflammatory effect, since mesalazine acts locally in the epithelial and submucous layer of the colon mucosa.
Therefore, the indicators of systemic bioavailability and the concentration of mesalazine in plasma are not important in terms of its therapeutic effectiveness, but rather serve as a factor in assessing its safety.
PHARMACOKINETICS

Suction

The greatest absorption of mesalazine occurs in the rectum and colon.

Metabolism

Mesalazine undergoes presystemic metabolism in the intestinal mucosa and systemic metabolism in the liver with the formation of a pharmacologically inactive metabolite of N-acetyl-5-aminosalicylic acid (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 by the action of bacterial microflora of the colon. The connection with the plasma proteins of mesalazine and N-Ac-5-ASA is 43% and 78%, respectively.
Excretion

Mesalazine and its metabolite N-Ac-5-ASA are excreted through the intestine (main part> 90%), up to 7% of the kidneys (0.6% of the total dose is excreted in the form of mesalazine and up to 6.3% in the form of metabolite N-Ac-5 -ASK), the degree of excretion of the drug with bile is minimal.

INDICATIONS

- exacerbation of distal forms of ulcerative colitis of moderate and mild degrees of severity;

- maintenance of remission of distal ulcerative colitis (long-term therapy).

DOSING MODE

The drug is applied rectally.

Adults and children over 12 years of age the drug is usually prescribed 1 time / day before bedtime (1 dose corresponds to 2 applications / strokes).
If such a volume of foam is difficult for the patient to keep in the rectum, the drug should be administered in two stages: once a night, and once again - at night or early in the morning (after defecation).
To achieve the best result, it is recommended to administer the drug after bowel movement (defecation).

The duration of the course of treatment is selected by the doctor individually.
As a rule, exacerbation of mild forms of ulcerative colitis can be stopped within 4-6 weeks. At the end of this period, the doctor decides on the appointment of mesalazine for oral administration as maintenance therapy.
The therapeutic effect is achieved with regular use of the drug.

Rules of drug administration

At the time of administration, it is necessary that the salofalk rectal foam preparation be at room temperature (20-25 ° C).

DRUG INTERACTION

Most of the possible drug interactions are based on theoretical assumptions.

With the simultaneous use of the drug with indirect anticoagulants, it is possible to enhance their effect: an increased risk of gastrointestinal bleeding.

When used simultaneously with GCS, there may be an increase in unwanted reactions from the stomach.

With simultaneous use with sulfonylureas, hypoglycemic effect may be increased.

With simultaneous use with methotrexate may increase the toxic effect of methotrexate.

When used simultaneously with probenecid, sulfinpyrazone, a reduction in the excretion of uric acid is possible.

With simultaneous use with spironolactone, furosemide, a weakening of the diuretic effect is possible.

When used simultaneously with rifampicin, the tuberculostatic effect may be weakened.

In patients who are simultaneously receiving treatment with azathioprine or mercaptopurine, the possible increase in the myelosuppressive effect of azathioprine and mercaptopurine should be borne in mind.
