Pharmacology

• Acyclovir is a synthetic purine nucleoside analogue with inhibitory activity against Herpes simplex viruses type 1 (HSV-1) and type 2 (HSV-2) in cell culture and in vivo. The inhibitory activity of Acyclovir is highly selective due to its affinity for the enzyme thymidine kinase (TK) encoded by HSV. This viral enzyme converts Acyclovir into Acyclovir monophosphate, a nucleotide analogue. The monophosphate is further converted into diphosphate by cellular guanylate kinase and into triphosphate by a number of cellular enzymes. In cell culture, Acyclovir Triphosphate stops replication of herpes viral DNA. This inhibition is accomplished in 3 ways:
• Competitive inhibition of viral DNA polymerase
• Incorporation into and termination of the growing viral DNA chain
• Inactivation of the viral DNA polymerase
• Hydrocortisone is the main glucocorticoid secreted by the adrenal cortex. It is used topically for its anti-inflammatory effects which suppress the clinical manifestations of the disease in a wide range of disorders where inflammation is a prominent feature.

Dosage & Administration
