Pharmacological action

Minaker - antiviral. The prodrug is a 6-deoxydiacetyl analogue of the active antiviral substance penciclovir. Transforming in the body into the active compound - penciclovir, acts on Herpes simplex viruses (types 1 and 2), Varicella zoster, Epstein-Barr virus.

Penetrating into virus-infected cells, penciclovir is phosphorylated by viral thymidine kinase to penciclovir monophosphate, which is then converted by action of cell kinases to penciclovir triphosphate. Penciclovir triphosphate is retained in an infected cell for more than 12 hours and inhibits viral DNA replication.

Has no effect on uninfected cells. It is active against some acyclovir-resistant strains of the Herpes simplex virus with altered DNA polymerase.

Pharmacokinetics

After oral administration, it is rapidly and almost completely absorbed and rapidly turns into active penciclovir. Bioavailability is 77%. TCmax - 45 min, Cmax after taking a single dose of 500 mg - 3.3-4.2 μg / ml. Distribution volume - 1 l / kg. Communication with plasma proteins - 20%.

T1 / 2 - 2.1-3 hours. T1 / 2 of penciclovir triphosphate from cells infected with herpes simplex virus type 1 - 10 hours, from cells infected with herpes simplex virus type 2 - 20 hours, from cells infected with varicella zoster virus - 7 h. T1 / 2 with CC less than 30 ml / min - 10-13 h.

Excreted by the kidneys by glomerular filtration and tubular secretion with urine (60-65% in the form of penciclovir), 27% with feces. Does not cumulate. It is excreted during hemodialysis.

with KK less than 30 ml / min - 125 mg 3 times a day.

For patients on hemodialysis, 250 mg (for patients with Varicella zoster) and 125 mg (for patients with genital herpes), the dose should be taken immediately after the procedure, because after 4 hours of hemodialysis, the concentration of penciclovir in the plasma is reduced by approximately 75%.
