Interactions
TiZANidine: CYP1A2 Inhibitors (Weak) may increase the serum concentration of TiZANidine. Management: Avoid these combinations when possible. If combined use is necessary, initiate tizanidine at an adult dose of 2 mg and increase in 2 to 4 mg increments based on patient response. Monitor for increased effects of tizanidine, including adverse reactions. Consider therapy modification

Management: When possible, discontinue antiviral agents with anti-zoster activity (i.e., acyclovir, valacyclovir, famciclovir) for at least 24 hours prior to and 14 days after receiving a live attenuated zoster vaccine. Avoid combination
Mycophenolate: Acyclovir-Valacyclovir may increase the serum concentration of Mycophenolate. Mycophenolate may increase the serum concentration of Acyclovir-Valacyclovir. Monitor therapy

Acyclovir - antiviral drug, a synthetic analogue of thymidine nucleoside, which has a highly selective effect on herpes viruses. Inside the virus-infected cells, a series of sequential reactions of the transformation of acyclovir into acyclovir mono- di- and triphosphate undergoes a viral thymidine kinase. Acyclovir triphosphate integrates into the viral DNA chain and blocks Xerese synthesis through competitive inhibition of viral DNA polymerase.
The specificity and very high selectivity of the action is also due to its predominant accumulation in cells affected by the herpes virus. Highly active against Herpes simplex virus type 1 and 2; chickenpox virus and herpes zoster (Varicella zoster); Epstein-Barr virus (types of viruses are listed in increasing order of magnitude of the minimum inhibitory concentration of acyclovir). Moderately active against cytomegalovirus.
With herpes, it prevents the formation of new elements of the rash, reduces the likelihood of skin dissemination and visceral complications, accelerates the formation of crusts, and reduces pain in the acute phase of herpes zoster.
Pharmacokinetics
After oral administration, the bioavailability is 15-30%, while dose-dependent concentrations Xerese created that are sufficient for the effective treatment of viral diseases. Food does not significantly affect the absorption of acyclovir. Acyclovir penetrates well into many organs, tissues and body fluids. Acyclovir crosses the blood-brain and placental barriers, accumulates in breast milk. About 84% is excreted by the kidneys unchanged, 14% - in the form of a metabolite. Less than 2% of acyclovir is excreted through the intestines.

- prevention of exacerbations of recurrent infections caused by Herpes simplex types 1 and 2 in patients with normal immune status;
- prevention of primary and recurrent infections caused by Herpes simplex viruses of types 1 and 2 in patients with immunodeficiency;
- as part of the complex therapy of patients with severe immunodeficiency: with HIV infection (AIDS stage, early clinical manifestations and an expanded clinical picture) and in patients undergoing bone marrow transplantation;
