Pharmacological properties
Pharmacodynamics
Acyclovir Belupo is an antiviral drug, the active ingredient of which, acyclovir, is a synthetic analogue of an acyclic purine nucleoside and has a high selective activity against herpes viruses. Under the influence of viral thymidine kinase, a series of successive reactions of transformation of acyclovir into mono-, di- and acyclovir triphosphate inside the cells affected by the virus occurs, after which acyclovir triphosphate is incorporated into the polynucleotide chain with viral DNA, blocking its synthesis due to competitive inhibition of viral DNA polymerase.
In vitro Acyclovir Belupo is active against the viruses Herpes simplex (herpes simplex types I and II) and Varicella zoster (human herpesvirus type III). In higher concentrations, the drug is effective against the Epstein-Barr virus (human herpesvirus type IV).
In vivo, Acyclovir Belupo is effective therapeutically and prophylactically, mainly for infections caused by the Herpes simplex virus.
Pharmacokinetics
With oral administration of Acyclovir Belupo, the bioavailability of acyclovir is 15 to 30%. It passes well into all tissues and organs, including the brain and skin. It binds to plasma proteins at a level of 9–33%, regardless of plasma concentration. The concentration in cerebrospinal fluid is ~ 50% of the level determined in plasma.
Acyclovir crosses the placental barrier and accumulates in breast milk. C max (maximum concentration) after oral administration of 200 mg 5 times / day is 0.7 μg / ml. T Cmax (time to reach C max) - from 1.5 to 2 hours.
Metabolism occurs in the liver, resulting in the formation of a pharmacologically inactive metabolite - 9-carboxymethoxymethylguanine.
In adult patients with normal renal function, T 1/2 (half-life) is 2-3 hours. In severe renal failure, T 1/2 increases to 20 hours, with hemodialysis, the indicator is 5.7 hours (the content of the substance in the plasma decreases up to 60% of the initial level). Acyclovir is excreted by the kidneys: unchanged - approximately 84%, in the form of a metabolite - 14%. Its renal clearance is 75–80% of the total plasma clearance. Less than 2% is excreted from the body through the intestines.
With external use of acyclovir: on intact skin - absorption is minimal, in blood and urine is not detected; on the affected skin - moderate absorption.
Indications for use
Acyclovir Belupo tablets:
- therapy of primary and secondary infectious lesions of the skin and mucous membranes (including genital herpes) caused by herpes simplex viruses of types I and II;
- therapy of primary and recurrent infections caused by human herpesvirus type III (chickenpox and shingles);
- complex therapy of patients with severe immunodeficiency [HIV-infected at the stages of early clinical manifestations and a detailed clinical picture of acquired immunodeficiency syndrome (AIDS)] and patients who underwent bone marrow transplantation;
- prevention in patients with normal immune status of exacerbations of recurrent infectious lesions caused by herpes simplex viruses type I and II;
- prevention in patients with immunodeficiency of primary and recurrent infections caused by herpes simplex viruses of types I and II.
Acyclovir Belupo cream is used to treat skin infections caused by herpes simplex virus types I and II (including genital herpes) and human herpesvirus type III (chickenpox and shingles).
Contraindications
Absolute:
- lactation period;

It is recommended to carry out the procedure 5 times a day, observing 4-hour intervals between applications of the drug.

The duration of the course is at least 5, but not more than 10 days.
Side effects
Acyclovir Belupo is generally well tolerated.
Possible side reactions from systems and organs when taking Acyclovir Belupo inside (tablets):
- digestive tract: in isolated cases - abdominal pain, nausea, vomiting, diarrhea;
- laboratory data: a transient slight increase in the activity of liver enzymes; rarely - a slight increase in the concentration of urea and creatinine levels, leukopenia, hyperbilirubinemia, erythropenia;
- central nervous system: rarely - weakness, headache; in isolated cases, dizziness, tremors, increased fatigue, confusion, hallucinations, drowsiness, paresthesia, agitation;
- immune system: allergic skin reactions (pruritus, urticaria, Lyell's syndrome, erythema multiforme, including Stevens-Johnson syndrome), anaphylactic reactions, peripheral edema;
- others: rarely - fever, myalgia, alopecia, visual impairment, lymphadenopathy.
The use of Acyclovir Belupo cream can contribute to the development of hyperemia, dryness, peeling of the skin, as well as burning and inflammation when it gets on the mucous membranes. In rare cases, allergic dermatitis may appear.
Overdose
When taking acyclovir orally at a dose of 20 g, the development of specific symptoms was not observed. There is a possibility of manifestation of such adverse reactions from the central nervous system, such as tremors, convulsions, lethargy.
In case of intoxication as a result of taking Acyclovir Belupo inside, it is necessary to induce vomiting (preferably within 30 minutes after the drug enters the digestive tract) and take absorbents.
Patients with acute renal failure and anuria may require maintenance of vital functions and hemodialysis.
Cases of overdose of Acyclovir Belupo with external use have not been reported to date.
special instructions
With prolonged or repeated treatment with acyclovir in patients with reduced immunity, viral strains may appear that are resistant to its action.
In order to avoid complications for adults and children over 3 years old, Acyclovir Belupo tablets must be taken strictly as prescribed by a doctor. Patients should be provided with a sufficient volume of fluid into the body, as well as control of renal excretory function by monitoring the level of urea and the concentration of creatinine in the blood plasma.
Since acyclovir does not protect against sexual transmission of herpes, it is important to refrain from sexual intercourse during therapy, even if there are no clinical manifestations of the disease.
In order to achieve the maximum therapeutic effect of Acyclovir Belupo cream, the course should be started as early as possible, with the development of the first symptoms of infection: burning, itching, tingling, feeling of tension and redness.
It is not recommended to apply the cream to the mucous membranes of the mouth and eyes, as this can cause severe local inflammation.
Influence on the ability to drive vehicles and complex mechanisms
There is no data.
Application during pregnancy and lactation
Adequate and well-controlled clinical studies of the safety of acyclovir during pregnancy have not been conducted.
Since acyclovir crosses the placental barrier, prescribing Acyclovir Belupo to pregnant women is possible only if the intended benefit to the woman exceeds the potential risk to the fetus.
During lactation, the drug accumulates in breast milk. If it is necessary to use Acyclovir Belupo during breastfeeding, the issue of transferring the child to artificial feeding should be resolved.
Pediatric use
Acyclovir Belupo tablets are not used to treat children under 3 years of age.
With impaired renal function
The drug is prescribed with caution to patients with impaired renal function, since they may have an increase in T 1/2 of acyclovir.
Correction of the dosage regimen for oral administration of Acyclovir Belupo, depending on the CC (creatinine clearance):
- treatment and prevention of infections caused by Herpes simplex (CC <10 ml / min): the dose of acyclovir is reduced to 200 mg 2 times / day at 12-hour intervals;
- treatment of infections caused by Varicella zoster: CC <10 ml / min - the dose is reduced to 800 mg 2 times / day at 12-hour intervals; CC 10-25 ml / min - 800 mg 3 times / day at 8-hour intervals.
Use in the elderly
Since the T 1/2 of acyclovir increases in elderly patients, treatment should be carried out with sufficient water load and under the supervision of a specialist.
Drug interactions
- probenecid: promotes an increase in the average T 1/2 and a decrease in acyclovir clearance;
- nephrotoxic drugs: increased risk of impaired renal function;
- immunostimulants: Acyclovir Belupo is able to enhance their effectiveness.
