Aciclovir 400mg tablets target the herpes simplex virus (HSV) and varicella-zoster virus (VZV), the culprits behind cold sores, genital herpes, and shingles.
Specifically, aciclovir mimics a building block of viral DNA. The virus incorporates aciclovir into its own DNA during replication. This creates faulty viral DNA, halting further viral reproduction.
- Aciclovir is a nucleoside analog. It’s structurally similar to guanosine, a natural component of DNA. Viral enzymes, mistaking aciclovir for guanosine, incorporate it into the growing viral DNA chain. This incorporation prevents further DNA chain elongation, effectively stopping viral replication.
The body then naturally breaks down the defective viral DNA. This process significantly reduces the viral load and alleviates symptoms.
The drug is absorbed into the bloodstream after oral administration. It reaches the infected cells, where it exerts its antiviral action. The effect is a reduction in the severity and duration of symptoms.
Remember, aciclovir doesn’t cure herpes infections; it manages symptoms and reduces viral shedding. Consistent adherence to prescribed dosage is crucial for optimal results.
