Valtsik

Valcic is a drug whose action is directed to the herpes virus, a skin disease affecting any part of the body, including the lips, external genitalia, eyes, and in severe cases, the CNS. Getting into the blood and lymph of a person contact or airborne, he remains for life. To date, there are no drugs that can cure this disease, but there are drugs that suppress its manifestations and reproduction. Valtsik also belongs to them.

Indications of the valtice

In total, eight types of herpes have been identified in humans. But the indications for the use of valcic are not all of its varieties. First of all, it is aimed at treatment:

  • Type 1 - herpes simplex, including the labial (on the lips), and also their relapses;
  • 2nd - genital herpes;
  • 3rd - shingles, manifested by bubble rashes on the skin and severe pain, chickenpox;
  • The 4th - the Epstein-Barr virus, which causes mononucleosis;
  • 6th type.

Also, the drug is used for preventive purposes:

  • Prevention of infection with cytomegalovirus (type 5), which occurs after organ transplantation;
  • in suppressive therapy.

The latter is common in Europe and America. It consists in prolonged use of the drug in order to avoid relapse of the disease.

Release form

The form of the drug - oblong convex in a blue shell tablets (0.5 g), one side of which with an impression of "VC" and "500", the other is smooth. There are tablets that are smooth on both sides. They are packed in 10 pieces in blisters or in bottles, containing 42 pieces.   

Pharmacodynamics

The active substance of valcic is valaciclovir hydrochloride, the content of one tablet is 500 mg. Pharmacodynamics of the drug is the following: during metabolic transformations under the action of the enzyme valacyclovirhydrolase, which is produced by the liver, it becomes a medicine, its activity is directed to the cells damaged by the virus by suppressing the synthesis of their DNA. In fact, it activates a specific enzyme produced by infected cells and making them an easily recognizable target. Valaciclovir also reduces the painful manifestations of herpes zoster, acute and postherpinal neuralgia, and reduces the possibility of kidney rejection due to transplantation surgery.  

Pharmacokinetics

Getting inside, valotsiklovir well absorbed, with one gram of the substance is digested slightly more than half. The maximum concentration in the body is achieved after an hour and a half after taking and is excreted by the urinary tract, the half-life period in people with healthy kidneys is 3 hours, in case of kidney failure - 14 hours.

In HIV-infected patients, the effect on the organism of valcic is the same as in healthy people participating in the trial. In patients who underwent kidney transplantation, there was an increase in its content.

Use of the valtice during pregnancy

Use during pregnancy is allowed in cases where the need for the drug exceeds the possible risk of side effects. To study the effect of the medicine on the body, 749 pregnant women in the first trimester of women were involved. Congenital defects of children from mothers who underwent systemic exposure to valacyclovir did not exceed this rate of infants born to healthy women. Nevertheless, to use the drug in this category of patients, this number of tests is considered insufficient.

  • kidney transplantation: children over 12 years and adults - on a tablet 4 times, the course of treatment - 3 months or more.

Overdose

Often an overdose occurs because elderly patients and people with kidney dysfunction problems do not adjust treatment doses. If necessary, their appointment should be cautious and take into account all the factors in the history of patients.
