Lyophilisate for the preparation of a solution for infusion of white or almost white color.

Pharmacological action

Antitumor agent, antimetabolite of the pyrimidine analog group, inhibits DNA synthesis. It shows cyclospecificity, acting on cells in phases S and Gl / S. It is metabolized in the cell under the action of nucleoside kinases to active diphosphate and triphosphate nucleosides. Diphosphate nucleosides inhibit the action of ribonucleotide reductase (the only enzyme that catalyzes the formation of deoxynucleoside triphosphates, necessary for DNA synthesis). Triphosphate nucleosides are able to integrate into the DNA chain (to a lesser extent RNA), which leads to the cessation of further DNA synthesis and programmed cell death (apoptosis).

Gemcitabine is also a powerful radiosensitizing agent, even at concentrations lower than cytotoxic.


Cmax gemcitabine (from 3.2 μg / ml to 45.5 μg / ml) is achieved 5 minutes after the end of the infusion. A pharmacokinetic analysis of single and multiple dose studies indicates that Vd is highly gender dependent. The binding of gemcitabine to plasma proteins is negligible.

In the body, gemcitabine is rapidly metabolized by the action of cytidine deaminase in the liver, kidneys, blood and other tissues, resulting in the formation of gemcitabine mono-, di- and triphosphates (dFdCMP, dFdCDP and dFdCTP), of which dFdCDP and dFdCTP are considered active.

Gemcitabine is rapidly excreted in the urine mainly as an inactive metabolite of 2′-deoxy-2 ‘, 2’-difluoruridine. Less than 10% of the iv dose is found in the urine in the form of unchanged gemcitabine. Systemic clearance, which ranges from about 30 l / h / m2 to 90 l / h / m2, depends on age and gender: the elimination rate in women is about 25% lower than in men, both in men and women, the excretion rate decreases with age.

T1 / 2 ranges from 42 minutes to 94 minutes. Subject to the recommended dosage regimen, complete elimination of gemcitabine occurs within 5-11 hours from the start of nnfusion. When administered once a week, gemcitabine does not accumulate in the body.

Combination therapy with gemcitabine and paclitaxel. With the joint administration of gemcitabine and paclitaxel, the pharmacokinetics of the drugs does not change.

Combination therapy with gemcitabine and carboplatin. With the joint administration of gemcitabine and carboplatin, the pharmacokinetics of gemcitabine does not change.

Impaired renal function. Mild or moderate renal failure (creatinine clearance 30-80 ml / min) does not significantly affect the pharmacokinetics of gemcitabine.

Special instructions

Treatment with gemcitabine can only be carried out under the supervision of a doctor with experience in the use of antitumor chemotherapy.

Before each administration of gemcitabine, it is necessary to control the number of platelets, white blood cells and granulocytes in the blood. With signs of inhibition of bone marrow function caused by the drug, it is necessary to suspend treatment or adjust the dose.

Typically, bone marrow suppression is short-term, does not require a dose reduction, and rarely leads to interruption of treatment. Peripheral blood counts may continue to deteriorate after interruption of gemcitabine therapy.

When using gemcitabine in combination with other antitumor chemotherapy drugs, the risk of cumulative suppression of bone marrow function must be considered.

Regular examination of the patient and assessment of renal and hepatic function is necessary.

Administration of gemcitabine in case of liver metastases, history of hepatitis and alcoholism, as well as liver cirrhosis increases the risk of liver failure. If there are signs of the development of adverse effects from the respiratory system (for example, pulmonary edema, interstitial pneumonitis or respiratory distress syndrome in adults) during treatment with gemcitabine, treatment should be discontinued and appropriate therapy should be prescribed.

When the first signs of microangiopathic hemolytic anemia appear, such as a rapid decrease in hemoglobin with concomitant thrombocytopenia, an increase in serum concentrations of bilirubin, creatinine, urea nitrogen, or an increase in lactate dehydrogenase activity, gemcitabine should be discontinued.

An increase in the duration of infusion and the frequency of administration leads to an increase in toxicity.

The risk of skin reactions increases with a history of radiation therapy.

Depending on the degree of toxicity, the dose can be reduced in each cycle or with the start of a new cycle stepwise.

Reliable contraceptive methods should be used during treatment and for 6 months after the end of gemcitabine therapy. Men receiving gemcitabine are advised to resort to Cree.

Reliable contraceptive methods should be used during treatment and for 6 months after the end of gemcitabine therapy. Men receiving gemcitabine are advised to resort to Cree.

Reliable contraceptive methods should be used during treatment and for 6 months after the end of gemcitabine therapy. Men receiving gemcitabine are advised to resort to Cree.sperm preservation before treatment due to the risk of infertility due to the use of this drug

Dose corrector for hematologic toxicity Start of the treatment cycle Regardless of the indications, pure platelets and granulocytes must be evaluated before each administration of the drug. The condition for starting treatment is an absolute neutrophil count of at least 1,500 / µl and a platelet count of at least 100,000 / µl. Dose adjustment for non-hematologic toxicity Periodic physical examination and monitoring of liver and kidney function should be performed to identify non-hematologic toxicity. The dose of the drug can be reduced in each subsequent cycle or during the already begun cycle, depending on the degree of manifestation of the toxicity of the drugs prescribed to the patient. In case of severe (3 or 4 degree) non-hematologic toxicity, with the exception of cases of nausea / vomiting, gemcitabine therapy should be suspended or the dosage should be reduced depending on the decision of the attending physician. The decision to resume treatment is made by the doctor. Method of administration The infusion of gemcitabine is usually well tolerated by patients and can be done on an outpatient basis. In case of extravasation, the infusion is stopped and the introduction of the drug into another vein is resumed. After administration of gemcitabine, the patient should be observed for some time. Side effects Adverse reactions that are more common than in single cases are listed inaccording to the following gradation: very often (> 10%) often (> 1% to <10%) infrequently (> 0.1% to <1%) rarely (> 0.01% to <0.1%) very rarely (<0.01%).

Drug Interactions No specific studies of gemcitabine interactions have been performed. Radiation therapy Concomitant radiation therapy (simultaneously with gemcitabine administration or with an interval <7 days before the start of treatment): in this situation, the toxicity of treatment depends on many factors, including the dose of gemcitabine and its frequency of administration, the radiation dose, the method of radiation therapy, the nature of the radiation therapy tissue and its volume. Gemcitabine has been shown to have radiosensitizing activity. In one study, where patients with non-small cell lung cancer received gemcitabine at a dose of 1000 mg / m2 for 6 consecutive weeks in combination with therapeutic radiation to the chest area, significant toxicity was noted, in the form of severe and potentially life-threatening inflammation of the mucous membrane, mainly esophagitis and pneumonitis , especially in patients with a large volume of tissue irradiation (median volume of irradiated tissue 4795 cm3). Subsequent studies have shown that a combination of lower doses of gemcitabine and radiation therapy is better tolerated by patients and has a predictable toxicity profile. So, in one phase II study, patients with non-small cell lung cancer underwent radiation therapy at a dose of 60 Gy with the introduction of gemcitabine (600 mg / m2 4 times) and cisplatin (80 mg / m2 2 times) for 6 weeks. Sequential therapy (interval> 7 days): according to existing data, the administration of gemcitabine more than 7 days before the start of radiation therapy or more than 7 days after its completion is not accompanied by an increase in toxicity, with the exception of skin lesions associated with the introduction of a chemotherapy after radiation . Treatment with gemcitabine can be started 7 days after irradiation or after resolving all acute radiation reactions.

Both with concomitant use and with consecutive use of gemcitabine and radiation therapy, radiation damage to the irradiated tissues is possible (e.g. esophagitis, colitis and pneumonitis).

Immunosuppressants (azathioprine, chlorambucil, glucocorticosteroids, cyclophosphamide, cyclosporine, mercaptopurine) increase the risk of infections.

Other types of interaction

When used with live viral vaccines, the replication of the vaccine virus may be intensified, its side / adverse effects may increase and / or antibody production in the patient’s body will be reduced in response to the vaccine. Therefore, due to the risk of systemic, possibly fatal complications, especially in patients with reduced immune status, the interval between the use of gemcitabine and such vaccines should be at least 3 months or more (up to 12 months), depending on the patient’s immune status.

Gemcitabine compatibility studies have not been conducted. Do not mix gemcitabine with other drugs.

Overdose of

Symptoms: myelodepression, paresthesia, severe skin rash. With the introduction of gemcitabine in doses up to 5700 mg / m2 iv in 30 minutes every 2 weeks there were no signs of overdose. The antidote for gemcitabine is unknown.

If an overdose of gemcitabine is suspected, the degree of cytopenia should be monitored and symptomatic therapy prescribed.
