Structure and Composition

1 vial with 0.2 ml concentrate for infusion (in absolute ethanol) containing 0.1 mg of alprostadil; 10 vials per box.

Pharmacology

Mode of action - vasodilator, antiagregatine, angioproteguoe.

Pharmacodynamics

It improves the microcirculation and peripheral circulation, dilates the arteries, arterioles and sphincter relaxes precapillaries; It improves the rheological properties of blood, increases the plasticity of erythrocytes; It affects hemocoagulation reducing platelet adhesion and aggregation. It has a fibrinolytic effect. It has anti-atherogenic effect, slowing the activation of neutrophils, excessive proliferation of vascular wall cells. Enhances collateral flow. The systemic and pulmonary vasodilatory effect of circulation. It helps increase blood flow to the cavernous bodies.

It reduces peripheral vascular resistance, blood pressure, reflex increases in heart rate, which leads to an increase in cardiac output. It stimulates the smooth muscles of the intestine, bladder and uterus; inhibits gastric acid secretion.

Pharmacokinetics

It is metabolized in the lungs to 60-90% (a single administration) by enzymatic oxidation with the formation of the three biologically active metabolites of 15-keto-PGE1, 15-keto-13,14-dihydro-PGE1, and 13,14-dihydro-PGE1 (PGE0 ). Ketometabolity have lower compared to alprostadil biological effect, metabolite, 13,14-dihydro-PGE1 (PGE0) has comparable with PGE1 action, but the duration. T1 / 2 is 10 to PGE1 and PGE0 - min 1 (alpha-phase) and 30 minutes (beta-phase). The main metabolites are excreted in the urine - 88% and feces - 12%.

Indications

Chronic obliterating diseases of arteries of the extremities stage III-IV (according to Fontaine classification), accompanied by pain at rest or trophic changes: occlusive disease with severe intermittent claudication (if not indicated surgery), atherosclerosis of arteries; diabetic angiopathy, Buerger's disease, Raynaud's syndrome with trophic disorders; vasculitis in systemic sclerosis; peripheral circulatory disorders due to exposure superlimiting vibration. Duktuszavisimye Congenital heart defects in newborns (to temporarily maintain the functioning of the ductus arteriosus before the reconstructive cardiac surgery).

Contraindications

Hypersensitivity, acute and subacute myocardial infarction, severe angina pectoris (including unstable), heart failure decompensation, arrhythmia, bronchial obstruction with severe signs of respiratory distress, swelling, or infiltrative lung changes, expressed human liver, a condition characterized by the risk of bleeding (gastric and duodenal ulcers, severe brain vascular proliferative retinopathy with a tendency to bleeding, extensive trauma); co-administration of vasodilators and anti-coagulant agents, pregnancy, breast-feeding; age 18 years (except for the neonatal period) and older than 75 years. In neonatology: inhibition of respiratory function, respiratory distress syndrome, a condition of spontaneous staunchly-patent ductus arteriosus.

Pregnancy and breast-feeding

Contraindicated. At the time of treatment should stop breastfeeding.

Side effects

From the nervous system and sensory organs: headache, dizziness, fatigue, somnolence, hypertonia of the neck muscles, increased irritability.

Cardio-vascular system and blood (blood, hemostasis): hypotension, tachycardia, angina, the AV block, leukocytosis, leukopenia, anemia, thrombocytopenia, bleeding, hypercapnia.

From the respiratory system: bradypnea or tachypnea.

From the digestive tract: a sense of discomfort in the epigastric region, nausea, vomiting, diarrhea, transient elevation of liver transaminases.

Other: malaise, increased sweating; possible swelling of the limbs, which is held in the vein infusion; hyperthermia, hypothermia, allergic reactions; reversible hyperostosis of long bones (for long - more than 4 weeks - treatment); increase in titer C-reactive protein, increase the level of potassium in the blood, hyperbilirubinemia, hematuria; shock, decreased renal function, anuria, hypoglycemia, tachyphylaxis.

When the side effects of the drug dose should be reduced.

Interaction

It enhances the effect of anticoagulants, antihypertensive agents, antiplatelet agents, and vasodilators.

Pharmaceutically compatible with other solutions (except saline, or 5% glucose solution 10).

Dosage and Administration

In chronic obliterating diseases of arteries of the lower extremities in adults: in / in, drip, at least 2 hours, 50-200 mcg (in 100-500 ml of normal saline or 5% glucose solution) 1 every day for more severe conditions - 50-100 mg 2 times a day. Recommended dilution: 1 drug vial (0.2 ml) diluted in 9.8 ml 5% glucose solution to give a concentration of 10 micrograms per 100 ml of solution; the resulting solution was diluted in 100-500 ml infusion solution (isotonic sodium chloride or 5% glucose solution). The course of treatment - 14 days, with good treatment effect continued for 7-14 days, the general course - no more than 4 weeks. If no effect within the first 2 weeks, treatment should be discontinued. When duktuszavisimyh congenital heart defects in newborns: in / in (via a large vein or via the umbilical artery directly into the mouth of the ductus arteriosus), drip. The initial rate of introduction - 0,01-0,05 g / kg / min. When the therapeutic effect dose reduced to the minimum maintenance - 0.01-0.02 g / kg / min. If necessary, the dose may be increased to 0.1 ug / kg / min.

Overdose

Symptoms: reduced blood pressure, redness of the skin, weakness.

Treatment: cessation of infusion; the oppression of the respiratory center in the newborn need to mechanical ventilation.

Precautionary measures

The I.V. the introduction may develop phlebitis (proximal to the injection site). This is usually not a reason for discontinuing treatment: inflammatory symptoms disappear a few hours after cessation of infusion or injection site change, a specific treatment in such cases is not required. Central venous catheterization can reduce the frequency of symptoms of this side effect. The number of adverse reactions is increased depending on the concentration and the rate of infusion. Increasing the infusion volume should be limited to patients with severe heart failure (risk of pulmonary edema and heart failure). Caution must be exercised in patients with hypertension; in elderly patients with insulin-dependent diabetes mellitus (especially when extensive vascular lesions), the appointment of a newborn in the case bradypnea, hypotension, tachycardia and hyperthermia.

When treatment is necessary to monitor hemodynamic parameters, acid-base balance, biochemical parameters and parameters of blood coagulation. A prerequisite use in newborns is the presence of the possibility of mechanical ventilation. The drug should be used under close medical supervision.

Patients with ischemic heart disease, renal failure (serum creatinine greater than 1.5 mg / L) should be monitored in the hospital during treatment and for 1 day after stopping treatment. To avoid the onset of symptoms of fluid overload of fluid administration should not exceed 50-100 ml per day. It should be a dynamic monitoring of the patient (control of blood pressure, heart rate), if necessary - control of body weight, fluid balance, measurement of central venous pressure, or echocardiography.

In patients on hemodialysis treatment with the drug should be performed in postdializnom period.

In patients with chronic lower limb arteries obliterating diseases of the use of the drug is part of a comprehensive treatment and clinical effect may occur after treatment.
