Pharmacokinetics Acyclovir properties rezorbirutsya from digestive tract only partially. Average peak concentration in plasma after repeated oral introduction of 200 mg, 400 mg and 800 mg of acyclovir of 5 times during the day make each 4 hours 3.02 & plusmn, 0.5 µmol/l (200 mg), 5.21 & plusmn, 1.32 µmol/l (400 mg) or 8.16 & plusmn, 1.98 µmol/l (800 mg). These values are reached approximately through 1.5 & plusmn, 0.6 hours. Concentration of acyclovir in blood plasma in 4 hours after the single oral use of acyclovir make 1.61 & plusmn, 0.3 µmol/l (200 mg), 2.59 & plusmn, 0.53 µmol/l (400 mg) or 4.0 & plusmn, 0.72 µmol/l (800 mg). In 24 hours after the termination of intake of acyclovir, drug is completely removed from an organism.
At children with immunosuppression aged from 3 up to 11 years after oral administration of 400 mg of acyclovir, i.e. 300-650 mg of acyclovir/sq.m of a body surface, 5 times during the day, average peak concentration in blood plasma make 5.7 – 15.1 µmol/l. At babies aged from 1 up to 6 weeks after oral introduction of 600 mg of acyclovir/sq.m of a body surface each 6 hours peak concentration in blood plasma made 17.3 or 8.6 µmol/l.
Acyclovir in high concentrations gets into fabrics and bodies and is slowly removed from them.
The volume of distribution is 50 & plusmn, 8.7 l / 1.73 sq.m at adults and 28.8 & plusmn, 9.3 l / 1.73 sq.m at newborns and babies up to 3 months. Linking with proteins of blood plasma was in range between 9 and 33%.
the highest concentrations of acyclovir are reached in intestines, kidneys, a liver and lungs, and lower – in muscles, heart, a brain, ovaries and seed plants of animals.
Acyclovir collects in saliva, a vaginal secret, vesicular liquid of herpetic bubbles and also in some bodies. Concentration of drug in cerebrospinal fluid equals 50% of concentration in serum.
Metabolism and elimination
At patients with normal function of kidneys of 62-91% of acyclovir are removed through kidneys in not changed look, and 10-15% in a look 9-carboxy-metoksimetilguanina. Removal of acyclovir is carried out both by glomerular filtration, and by canalicular secretion.
At patients with chronic kidney disease the average half-life period is about 19.5 hours. The average half-life period during a hemodialysis is 5.7 hours. During a hemodialysis the acyclovir level in plasma falls approximately for 60%. At bounded function of kidneys and clearance of creatinine of 10 ml/min. / 1.73 the sq.m exists danger of cumulation at a dosage on 200 mg of 5 times a day. Therefore at the above-stated clearance of creatinine the drug dose decline is shown (see also section Route of administration and doses).
Acyclovir is pharmacological inactive substance which is transformed to antiviral means only after penetration into the cell infected with viruses of a herpes simplex (HSV) or the varicella-zoster (VZV) viruses. After system use this activation of acyclovir is exposed to catalytic action from a thymidinekinase of the HSV or VZV viruses, enzyme which is necessary for replication of these viruses. In the simplified look it is possible to tell that the virus synthesizes own antiviral means. At the same time this process goes through the following stages:
1. after system use, acyclovir gets in a strengthened way into the cells infected with herpes,
2. the virus thymidinekinase which is in these cells phosphorylates acyclovir in acyclovir monophosphate,
3. cellular enzymes turn acyclovir monophosphate into own antiviral means, acyclovir triphosphate,
4. acyclovir triphosphate selectively blocks synthesis of virus DNA,
5. the virus DNA polymerase includes acyclovir in virus DNA therefore there is a break of a chain at DNA synthesis.
These separate stages lead to suppression of replication of a virus.
Spectrum of action
Highly sensitive viruses: a herpes simplex virus like I and II, the varicella-zoster virus.
Sensitive viruses: Epstein-Burra’s virus.
Insensitive to resistant: cytomegalovirus.
Resistant viruses: RNA viruses, adenoviruses, poksvirusa.
Aciclostad, 200 mg of a tablet
– the infections caused by a herpes simplex virus, in particular, herpes of skin and mucous membrane of genitalias (primary and often recurrent herpes of genitalias)
– preventive treatment of the adult patients suffering from very severe forms of often recurrent infections of the genitalias caused (Negres of genitalis).
Aciclostad, 400 mg of a tablet
– Herpes Zoster (shingles)
– prevention of the heavy infections caused by a herpes simplex virus at adult patients with a pronounced immunosuppresiya at the increased risk of infection, for example, after organ transplantation.
Aciclostad, 800 mg of a tablet
– Herpes Zoster (shingles).
A route of administration and doses
In the infections caused by a herpes simplex virus
to accept the Single dose of 200 mg of an Aciclostad 5 times during the day each 4 hours.
For prevention of severe forms and often recurrent infections of the genitalias caused by a herpes simplex virus:
Immunological healthy patients accept a single dose of 200 mg of an Aciclostad 4 times in every day of 6 hours. As an alternative it is also possible to accept daily 400 mg of an Aciclostad each 12 hours. In some cases effective prevention can be reached at a dosage on 200 mg of an Aciclostad 3 times in every day of 8 hours or on 200 mg of an Aciclostad 2 times in every day of 12 hours. If, despite the general daily dose of 800 mg the recurrence (resuming of an infection) takes place, then it is necessary to accept 200 mg of an Aciclostad of 5 times within a day each 4 hours for 5 days. After that accept the above-stated preventive doses again.
To patients with immunosuppression appoint for prevention a single dose of 200 mg of an Aciclostad 4 times in every day of 6 hours.
To patients with pronounced immunosuppression, for example, after organ transplantation, it is possible to appoint 400 mg of an Aciclostad 4 times in every day of 6 hours. As an alternative, at patients with the broken resorption in intestines, it is possible to use acyclovir in the form of dry matter for intravenous injections.
Duration of preventive use depends on extent of easing of immunity.
For treatment of the infections caused by a herpes simplex virus, to children 2 years are more senior give an adult dose, aged up to 2 years – a half of an adult dose.
At patients with immunosuppression cases of possible development of resistance were described. It should be considered at a dosage.
In shingles (Herpes zoster)
to accept the Single dose of 800 mg of an Aciclostad 5 times within a day each 4 hours. Duration of treatment is 5-7 days.

Probenetsid reduces removal of an Aciclostad kidneys approximately by 30% that can lead to increase in its average elimination half-life.
instructions Pregnancy and a lactation
If during pregnancy the therapy by Aciclostad is required, then it is necessary to compare carefully possible advantage and potential risk.
Features of influence of medicine on ability to run the vehicle or potentially dangerous mechanisms
Considering side effects of drug it is necessary to be careful at control of motor transport or the mechanisms demanding concentration of attention.
So far at the single oral use of a dose up to 5 g no symptoms of poisoning were observed. About the single oral use of higher doses there are no data. Therefore at the use of an Aciclostad in doses over 5 g it is necessary to carry out careful control of a condition of the patient through short periods. Symptomatic treatment.
Aciclostad is brought at a hemodialysis.
