The active ingredient of Zovirax is acyclovir. It was patented in 1974 and approved for medical use in 1981. The developer of acyclovir, the American pharmacologist Gertrude Elion, won the Nobel Prize in Physiology or Medicine in 1988 for developing the principles of creating drugs focused on "biomolecular targets”, which include Zovirax.
How does Zovirax work?
The effect of Zovirax is associated with the similarity of its active ingredient acyclovir with guanosine, which is a normal component of DNA. In the course of a number of microbiological reactions, acyclovir inhibits the processes occurring in the viral DNA, while the drug acts selectively on the synthesis of viral DNA. The replication of the host cell DNA (human cells) is practically not affected by its metabolites.
Zovirax is active against most herpes viruses: herpes simplex virus type I and II, varicella-type virus, Epstein-Barr virus, human herpes virus type 5. It prevents the formation of new elements of the rash, reduces the likelihood of cutaneous dissemination and visceral complications, accelerates the formation of crusts, relieves pain in the acute phase of herpes zoster. The drug also has an immunostimulating effect.
How to use Zovirax?
Zovirax is available in the form of an ointment for external use, pills and powder for preparation solutions for injection. The dosage and treatment regimen depends on the specific disease, its severity and individual reactions to the components of the drug. Before ordering Zovirax in our pharmacy, you should consult with your doctor.
In patients with severe immunodeficiency, prolonged or repeated courses of therapy with acyclovir can lead to the formation of resistant strains, and therefore further treatment with acyclovir may be ineffective.
