Pharmacological action
Pharmacodynamics
Antitumor drug, antimetabolite group of pyrimidine analogues, inhibits DNA synthesis. It shows cyclospecificity, acting on cells in phase S and at the boundary of phases G1 and 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 lysis (apoptosis).
Gemcitabine is also a powerful radiosensitizing agent, even at concentrations lower than cytotoxic.
Pharmacokinetics of
Cmax gemcitabine (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, of which gemcitabine di- and triphosphates are considered active.
Gemcitabine is rapidly excreted by the kidneys mainly in the form of 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.
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 the infusion. 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 to moderate renal failure (creatinine clearance 30-80 ml / min) does not significantly affect the pharmacokinetics of gemcitabine.
Indications
Locally advanced or metastatic non-small cell lung cancer as first-line therapy in combination with cisplatin and monotherapy in elderly patients with a functional status of 2 (ECOG-BOP)

Drug Interaction
Radiotherapy
Concomitant radiotherapy (concomitant with the introduction of hematite or at intervals <7 days prior to treatment): in this situation, the toxicity of treatment depends on many factors, including dose, radiation therapy, the nature of the irradiated 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 observed in the form of severe and potentially life-threatening mucosal inflammation esophagitis and pneumonitis, especially in patients with high tissue irradiation (median irradiated tissue volume 4795 cm3). Subsequent studies have shown that the combination of lower doses of gemcitabine and radiation therapy is better tolerated by patients and is characterized by a predictable toxicity profile. For example, in one phase II study, patients with non-small cell lung cancer were treated with radiation at a dose of 60 Gy together with the administration of gemcitabine (600 mg / m2 4 times) and cisplatin (80 mg / m2 2 times) for 6 weeks.
Sequential therapy (break> 7 days): According to existing data, the introduction of gemcitabine more than 7 days before the start of radiation therapy or more than 7 days after its completion is not accompanied by increased toxicity, except for skin lesions associated with the introduction of chemotherapy after irradiation . Gemcitabine treatment may be initiated 7 days after irradiation or after resolution of all acute radiation reactions.
Concomitant and sequential use of gemcitabine and radiation therapy may cause radiation damage to the irradiated tissues (eg, esophagitis, colitis, and pneumonitis).
Other types of interaction
When used with live attenuated vaccines, intensification of the vaccine replication process, enhancement of its adverse / adverse effects, and / or decreased antibody production in the patient's body in response to the administration of the vaccine.
Immunosuppressants (including azathioprine, chlorambucil, GCS, cyclophosphamide, cyclosporine, mercaptopurine) increase the risk of infection.
No compatibility studies have been performed on hematite. It is not recommended to mix Hemit preparation with other medicines.
Overdose
The antidote for gemcitabine is unknown. With the introduction of the drug Gemit in doses up to 5700 mg / m2 in / in a drop for 30 min every 2 weeks the level of toxicity of treatment remained acceptable. If gemcitabine overdose is suspected, the degree of cytopenia should be monitored and supportive therapy prescribed.
Storage conditions
Keep out of the reach of children at a temperature not exceeding 25 РC. Do not freeze.
Expiration
2 years.
