Aciclovir is an antiviral drug that is changed over to monophosphate by thymidine kinase that is specific for viruses then additionally changed over to triphosphate by other cell catalysts. This drug restrains DNA synthesis and viral replication by contending with deoxyguanosine triphosphate for viral DNA polymerase and being fused into viral DNA.
This drug is known as an antiviral drug and is used to treat herpes zoster or shingles. However, this drug cannot treat herpes virus infections completely but only lessens the viral load in the body. This drug facilitates faster healing of lesions, prevents new complications and lessens the pain or itchiness associated with the disease. In some cases, aciclovir helps people with weak immune systems prevent viruses from spreading in the different areas of the body. This drug can be in the form of a tablet, syrup or cream.
