Recommended dilution: dissolve the contents of 1 ampoule with lyophilisate (0.2 ml) in 9.8 ml of solvent (5% or 10% glucose solution, physiological solution). After dilution, the concentration of alprostadil in 10 ml of solution is 100 μg. The resulting solution, if necessary, can be diluted in a larger volume of solvent.
Adult patients are prescribed 50-200 mcg 1 time per day. In severe cases, the dose is increased to 50-100 mcg 2 times a day. The lyophilisate is usually dissolved in 200-500 ml. The duration of the infusion is at least 2 hours.
The average duration of treatment is 14 days. In case of a positive effect, therapy is continued for another 7-14 days. The total duration of the drug should not exceed 28 days.
If there is no effect during the first 14 days of treatment, Alprostan is canceled.
For patients with impaired renal function (serum creatinine concentration greater than 1.5 ml / dl), the initial dose is 20 μg. After 2-3 days, if necessary, the dose is increased to 40-60 mcg.
With heart and renal failure, the maximum volume of injected fluid is 50-100 ml per day.
The duration of treatment for these categories of patients is 28 days.

special instructions
Alprostan should be used only by medical specialists with experience in angiology, familiar with modern methods of continuous monitoring of the state of the cardiovascular system and having the appropriate equipment for this.
During the period of treatment, it is necessary to monitor the hemodynamic parameters of the acid-base balance, the biochemical parameters of the blood and the blood coagulation system (in patients with disorders of the blood coagulation system or receiving simultaneous therapy with drugs that affect the hemocoagulation system).
In case of side effects, it is recommended to reduce the dose of the drug.
Patients with renal failure and coronary heart disease during treatment and within 1 day after its completion should be in the hospital under the supervision of a doctor. In order to avoid the development of overhydration, it is desirable that the volume of injected fluid in such patients does not exceed 50-100 ml per day. Patients should be carefully monitored: blood pressure and heart rate, if necessary, body weight, fluid balance, central venous pressure, or echocardiography. In newborns, Alprostan should be used under constant monitoring of blood pressure, if conditions are available for mechanical ventilation.
Treatment of patients on hemodialysis should be carried out in the post-dialysis period.
In patients with chronic obliterating diseases of the arteries of the lower extremities, the use of Alprostan is part of a complex therapy, the clinical effect of the treatment is long-lasting and may appear with a certain delay after the end of the therapeutic course.
Alprostane can cause systemic effects in the form of dizziness, weakness or hypotension, which usually disappear soon after the cessation of infusions, so patients should be careful when driving and performing activities that require increased speed of psychomotor reactions and concentration.
