How does Acyclovir work in the body?
Acyclovir works by interfering with the viral DNA replication process. It is a synthetic nucleoside analogue that, once inside the body, is converted into acyclovir triphosphate. This active form inhibits the viral DNA polymerase enzyme, which is crucial for the virus to replicate and spread. By halting the replication process, Acyclovir helps to reduce the severity and duration of outbreaks, allowing the body's immune system to combat the virus more effectively.
In what forms is Acyclovir available?
Acyclovir is available in multiple dosage forms to accommodate different treatment needs and preferences. These include oral tablets and capsules, which are commonly prescribed for systemic infections. Additionally, Acyclovir is available as a topical cream or ointment for direct application to the skin, particularly for treating cold sores and other localized infections. For severe cases, an intravenous form of Acyclovir may be administered in a hospital setting.
