Pharmacological action

Zilt - antiplatelet agent.

Clopidogrel prevents the binding of adenosine phosphate (ADP) to receptors located on the surface of platelets and the activation of the GP IIb / IIIa complex. This leads to inhibition of ADP-dependent platelet aggregation. This also leads to inhibition of platelet aggregation under the influence of other stimuli, the effect of ADP produced in each activated platelet is reduced, and aggregation of the remaining platelets is stimulated.

The effect of clopidogrel lasts throughout the life of the platelet, platelet function is restored 7-10 days after the cancellation of clopidogrel.

Indications

Prevention of ischemic disorders (myocardial infarction, stroke, peripheral arterial thrombosis, sudden vascular death) in patients with atherosclerosis, including after myocardial infarction (up to 35 days), ischemic stroke (from 7 days to 6 months), or against a background of diagnosed peripheral arterial occlusion diseases.

Contraindications

Hypersensitivity to clopidogrel and / or any of the components Sylt

Severe hepatic insufficiency

Hemorrhagic syndrome, acute bleeding (including intracranial hemorrhage) and diseases that predispose the intestine to the stomach ( , ulcerative colitis, tuberculosis, lung tumors, hyperfibrinolysis)

Pregnancy

Lactation

Age up to 18 years.

Special instructions

In patients with myocardial infarction, treatment with Zilt should not begin in the first few days after a heart attack. Clopidogrel prolongs bleeding time. Zilt should be prescribed with caution to patients with an increased risk of bleeding after injuries, operations or as a result of other pathological conditions, as well as to patients with a tendency to bleeding (especially gastrointestinal and intraocular hemorrhages). Clopidogrel treatment should be discontinued at least 7 days before the planned surgical intervention (including dental procedures).

Musculoskeletal system: arthralgia, back pain, arthritis, arthrosis.

Drug Interactions

Concomitant use of clopidogrel and oral anticoagulants is not recommended (increased bleeding intensity is possible).

The simultaneous use of clopidogrel and IIb / IIIa receptor blockers requires caution in patients with an increased risk of bleeding (for injuries, surgical interventions or other pathological conditions requiring the simultaneous administration of IIb / IIIa glycoprotein inhibitors).

Acetylsalicylic acid (ASA) does not affect clopidogrel-induced platelet aggregation inhibition induced by ADP, but clopidogrel potentiates the effect of ASA on collagen-induced platelet aggregation. However, the simultaneous administration of ASA in a dose of 500 mg 2 times / day. within one day does not significantly extend the bleeding time caused by clopidogrel. The pharmacodynamic interaction between clopidogrel and ASA is possible, and leads to an increased risk of bleeding. Given this, caution should be exercised while taking these drugs, although in clinical trials, patients took combination therapy with clopidogrel and ASA for one year.

According to a clinical study in healthy individuals, when taking clopidogrel, there was no need to change the dose of heparin, and also did not change the anticoagulant effect of heparin. The combined use of heparin did not affect the suppression of platelet aggregation by clopidogrel. A pharmacodynamic interaction between clopidogrel and heparin is possible, leading to an increased risk of bleeding. Therefore, the simultaneous use of these drugs requires caution.

The safety of the simultaneous use of clopidogrel, fibrin-specific or non-specific thrombolytics and heparin has been evaluated in patients with acute myocardial infarction. The incidence of clinically significant bleeding was comparable to that with the simultaneous use of thrombolytics, heparin with ASA.

According to a clinical study involving healthy volunteers, the simultaneous use of clopidogrel and naproxen increased latent gastrointestinal bleeding. However, due to the lack of studies on interactions with other NSAIDs, it is currently unknown whether the risk of gastrointestinal bleeding increases for all NSAIDs. Therefore, simultaneous therapy of NSAIDs, including COX-2 inhibitors, and clopidogrel should be carried out with caution.

Another combination therapy: several clinical studies have been performed with clopidogrel and other concurrently used drugs to study possible pharmacodynamic and pharmacokinetic interactions.

- with the simultaneous use of clopidogrel with atenolol and / or nifedipine, no clinically significant pharmacodynamic interaction was detected

- the pharmacodynamic activity of clopidogrel did not change significantly when combined with phenobarbital, cimetidine or estrogens

- the pharmacokinetics of digoxin or theophylline did not change

- antacids do not significantly affect the degree of absorption clopidogrel. However, it is possible to inhibit the activity of cytochrome P450 with the 2C9 isoenzyme by the carboxyl metabolite of clopidogrel. Potentially, this can lead to increased plasma concentrations of drugs, such as phenytoin and tolbutamide, as well as NSAIDs that are metabolized by cytochrome P450 2C9

- in addition to the specific interactions with the drugs described above, other studies have not been conducted. However, in patients participating in clinical studies with clopidogrel and simultaneously taking diuretics, beta-blockers, ACE inhibitors, calcium antagonists, hypolipidemic agents, coronary vasodilators, hypoglycemic agents (including insulin), antiepileptic drugs and antagonists glycoprotein IIb / IIIa has not been identified clinically significant interactions.

Overdose

Symptoms: an overdose of clopidogrel can lead to an increase in bleeding time and subsequent complications in the form of bleeding.

Treatment: in order to correct the prolonged bleeding time, platelet transfusion is necessary. There is no antidote.

Storage Conditions

The product should be stored in a dry, dark place at a temperature not exceeding 20 ° C.
