Description of the drug approved by the manufacturer for the printed edition of 2017.


Isoprinosine is a synthetic complex derivative of purine, which possesses immunostimulating activity and nonspecific antiviral action.
It restores the functions of lymphocytes under conditions of immunodepression, increases blastogenesis in a population of monocytic cells, stimulates the expression of membrane receptors on the surface of T-helpers, prevents the decrease in activity of lymphocyte cells under the influence of glucocorticosteroids, normalizes the incorporation of thymidine into them. Isoprinosine exerts a stimulating effect on the activity of cytotoxic T-lymphocytes and natural killers, the function of T-suppressors and T-helpers, increases the production of IgG, interferon gamma, interleukins (IL-1) and IL-2, reduces the formation of pro-inflammatory cytokines-IL-4 and IL-10, potentiates the chemotaxis of neutrophils, monocytes and macrophages.
The drug exhibits antiviral activity in vivo against the viruses Herpes simplex, cytomegalovirus and measles virus, human T-cell lymphoma virus type III, polioviruses, influenza A and B, ECHO virus (enterocytopathogenic human virus), encephalomyocarditis and equine encephalitis.
The mechanism of antiviral action of Isoprinosin is associated with the inhibition of viral RNA and the enzyme dihydropteroate synthetase involved in the replication of certain viruses. Strengthens the virus-suppressed synthesis of mRNA lymphocytes, which is accompanied by suppression of the biosynthesis of viral RNA and translation of viral proteins, increases the production of lymphocytes with alpha and gamma interferons possessing antiviral properties.
When combined, increases the effect of interferon alfa, antiviral agents of acyclovir and zidovudine.



After oral administration, it is well absorbed from the digestive tract.
C max of the active substance in the blood plasma is determined after 1-2 hours.

Rapidly exposed to metabolism.
Metabolized similarly to endogenous purine nucleotides with the formation of uric acid, NN-dimethylamino-2-propranololone is metabolized to the N-oxide, and para-acetamidobenzoate to o-acylglucuronide. No cumulation of the drug in the body.

T 1/2 is 3.5 hours for NN-dimethylamino-2-propranololone and 50 minutes for para-acetamidobenzoate.
It is excreted by the kidneys. Elimination of the drug and its metabolites from the body occurs within 24-48 hours.

In severe forms of infectious diseases, the dose can be increased individually to 100 mg / kg of body weight / day, divided into 4-6 receptions.
The maximum daily intake for adults is 3-4 g / day, for children - 50 mg / kg / day.
The duration of treatment for acute diseases in adults and children is usually from 5 to 14 days.

With chronic relapsing diseases in adults and children, treatment should be continued with several courses for 5-10 days with a break in admission in 8 days.

For maintenance therapy, the dose can be reduced to 500-1000 mg / day (1-2 tablets) for 30 days.

In herpetic infection, adults and children are prescribed a drug for 5-10 days before the symptoms disappear, in the asymptomatic period - 1 tab.
2 times / day for 30 days to reduce the number of relapses.
With papillomavirus infection, adults are prescribed 2 tab.
3 times / day, children - 1/2 tab. at 5 kg / body weight / day in 3-4 doses for 14-28 days in the form of monotherapy.
With recurrent genital warts, adults are prescribed 2 tab.
3 times / day, children - 1/2 tab. at 5 kg / body weight / day in 3-4 doses, either as monotherapy or in combination with surgical treatment for 14-28 days, then with a three-fold repetition of this course at intervals of 1 month.

After 4 weeks of use, it is advisable to monitor kidney function every month (level of creatinine, uric acid).


After 4 weeks of use, it is advisable to monitor liver function every month (transaminase activity).


Contraindication: children under 3 years old (body weight up to 15-20 kg).


After 2 weeks of using Isoprinosine, it is recommended to monitor the content of uric acid in the serum and urine.

With prolonged admission after 4 weeks of use, it is advisable to monitor liver and kidney function every month (transaminase activity in blood plasma, creatinine, uric acid level).

It is necessary to monitor the level of uric acid in the blood serum when prescribing Isoprinosine in combination with drugs that increase the level of uric acid or drugs that disrupt kidney function.
