• Description: As it is evident from the chemical structure, acyclovir looks like a nucleoside analog of guanosine in side chain of which, instead of the traditional cyclic sugar residue a 2-hydroxyethoxymethyl acyclic side chain is present. Acyclovir possesses antiviral activity with respect to types 1 and 2 of herpes simplex, shingles virus, Epstein–Barr virus, and cytomegalovirus.
• Uses: Acyclovir (Zovirax) is a synthetic purine analog derived from guanine. It exerts its effects on the herpes simplex virus (HSV) and varicella-zoster virus by interfering with DNA synthesis through phosphorylation by viral thymidine kinase and subsequent inhibition of viral DNA polymerase, thereby inhibiting viral replication. It is effective against HSV-1 and 2, varicella-zoster virus, Epstein-Barr virus, herpesvirus simiae, and cytomegalovirus. Acyclovir may be administered intravenously, orally, or topically. Orally active acyclic nucleoside with inhibitory activity towards several herpes viruses. Antiviral; hypnotic. Inhibits cytomegalovirus replication; induces apoptosis
• Indications: Acyclovir (Zovirax) is a synthetic purine analog derived from guanine. It exerts its effects on the herpes simplex virus (HSV) and varicella-zoster virus by interfering with DNA synthesis through phosphorylation by viral thymidine kinase and subsequent inhibition of viral DNA polymerase, thereby inhibiting viral replication. It is effective against HSV-1 and 2, varicella-zoster virus, Epstein-Barr virus, herpesvirus simiae, and cytomegalovirus. Acyclovir may be administered intravenously, orally, or topically.Acyclovir (400 mg PO b.i.d. or 200 mg PO five times a day) or other antiviral antibiotics can suppress herpes-associated EM. It is of no value once the EM has started. Not all episodes of a herpes simplex recurrence are associated with EM, but in recurrent cases, a 6-month trial of suppressive therapy can be helpful.
• Therapeutic Function: Antiviral
• Clinical Use: Aciclovir Herpes simplex keratitis Chickenpox and herpes zoster Herpes simplex encephalitis and neonatal herpes Prophylaxis of HSV infections in the severely immunocompromised Valaciclovir Herpes zoster and genital HSV infections
