INSTRUCTION FOR THE SPECIALIST.

Description of the drug approved by the manufacturer for the printed edition of 2011.

PHARMACHOLOGIC EFFECT

The drug Realdiron ® has antiviral, immunomodulating, antiproliferative and antitumor effect.

Interferon alfa, interacting with related receptors on the cell surface, initiates a complex chain of changes within the cell.
It is assumed that these processes are associated with preventing the replication of viruses in the cell, inhibiting the proliferation of cells and immunomodulating action of interferon. Interferon alfa has the ability to stimulate the phagocytic activity of macrophages, as well as the cytotoxic activity of T cells and "natural killers." These properties of interferon and caused the therapeutic effect of the drug Realdiron ® .
PHARMACOKINETICS

Data on the pharmacokinetics of the preparation of Realdiron ® are not available.

INDICATIONS

Viral diseases:

- Acute hepatitis B;

- chronic active hepatitis B;

- chronic hepatitis C;

tick-borne encephalitis.

Oncological diseases:

- hairy cell leukemia;

- chronic myelogenous leukemia;

- Renal cell carcinoma;

- Kaposi's sarcoma on the background of AIDS;

- cutaneous T-cell lymphoma (mushroom mycosis and Cesari syndrome);

- malignant melanoma.

DOSING MODE

Solution of the drug Realdiron ® is administered in / m or s / c.
Before use, the contents of the ampoule or vial are dissolved in 1 ml of water for injection. The drug dissolves quickly, regardless of the dose contained in the vial or ampoule. The drug solution is a colorless, transparent or slightly opalescent liquid. Realdiron ® does not contain preservatives, therefore, in order to avoid bacterial contamination, only freshly prepared solution should be used.
Viral diseases

For acute hepatitis B (light, moderate and severe forms), 1 million IU is prescribed 2 times / day for 5-6 days, then the dose is reduced to 1 million IU once / day and injected for another 5 days.
If necessary (after controlling biochemical blood tests to assess the functional state of the liver), treatment can continue for another 2 weeks, during which the drug is administered 1 million IU 2 times a week.
In acute hepatitis B, the preparation Realdiron ® is most effective at the beginning of icteric period before the 5th day of jaundice.
At the appointment in later terms, the effectiveness of the drug is reduced. With cholestatic flow of the disease or with developing hepatic coma, Realdiron ® is ineffective.
In chronic active hepatitis B, the preparation Realdiron ® is prescribed 3-6 million IU 3 times a week for 24 weeks.
If after therapy for 12 weeks. there is no clinical improvement, improvement of biochemical parameters of blood and / or disappearance of HBsAg, the drug is canceled.
In chronic hepatitis C, the preparation Realdiron ® is prescribed 3 million IU 3 times a week for 24 weeks.
If after the introduction of the drug for 4 weeks there is no decrease in 50% of the activity of ALT in the blood plasma, the dose of the drug is increased to 6 million IU 3 times a week. If after 12 weeks of therapy there is no clinical improvement, improving the biochemical parameters of the blood, the drug should be discarded.
With meningeal forms of tick-borne encephalitis, the preparation Realdiron ® is administered on 1-3 million IU 2 times / day for 10 days.
Then they switch to maintenance therapy - 5 injections of 1-3 million IU every 2 days.
Oncological diseases

The general principle of the use of interferon in cancer is to prescribe the maximum dose that the patient can tolerate for a sufficiently long time (months, years).Because
interferon alfa has a cytostatic effect, supporting treatment with the drug Realdiron ® should continue and after achieving a clinical effect - hematological remission, regression of solid tumor sites.
With hairy cell leukemia , 3 million IU daily is administered.
After achieving hematologic remission go to supportive therapy - 3 million IU 3 times a week for 2 months, then treatment can not continue. When relapse treatment is repeated.
With chronic myelogenous leukemia appoint 9 million IU daily.
After achieving hematologic remission, 9 million IU are prescribed 3 times a week. The duration of treatment is determined by the attending physician depending on the nature of the course of the disease.
In renal cell carcinoma, REALDIRON® is administered to 18 million IU three times a week.
The clinical effect (complete or partial regression of metastases) is observed after 8-12 weeks of treatment with the drug Realdiron ® or later. When the therapeutic effect or stabilization of the course of the disease is achieved, maintenance therapy is continued for 18 million IU three times a week. The duration of treatment is determined by the attending physician depending on the nature of the course of the disease. When the process progresses, the treatment with the drug can be replaced by the attending physician with antitumor therapy.
With Kaposi's sarcoma , 36 million IU are prescribed daily against AIDS .
The drug is used for a long time, except for cases of rapid progression of the disease or severe intolerance of the drug. After achieving therapeutic effect, maintenance therapy is prescribed - 18 million IU 3 times a week.
With cutaneous T-cell lymphoma (fungal mycosis and Sesari syndrome), the preparation Realdiron ®
appoint 18 million IU daily. The duration of treatment is determined by the attending physician depending on the nature of the course of the disease.
In malignant melanoma, the preparation Realdiron ® is prescribed for 18 million IU daily.
After achieving a clinical effect (complete or partial regression of metastases) go on supporting therapy - 18 million IU 3 times a week. Adjuvant therapy with the drug Realdiron ® for 18 million IU 3 times a week, prescribed after surgical removal of the primary tumor of melanoma I-II stage or metastases in the regional lymph nodes, contributes to an increase in the duration of remission and the survival of patients.
SIDE EFFECT

Influenza -like symptoms are possible : most often - chills, fever, fatigue, lethargy, headache, joint pain, myalgia, loss of appetite.
These symptoms are partially suppressed by acetaminophen or paracetamol.
Possible minor leukopenia, thrombocytopenia, changes in liver function.
These adverse reactions disappear when the preparation Revaldiron ® is discontinued or its dose is reduced.
