valacyclovir + mecobalamin

valacyclovir + mecobalamin is a combination therapy used for the treatment of herpes zoster (shingles). Valacyclovir hydrochloride is an antiviral prodrug that is converted to acyclovir, which inhibits viral DNA polymerase, thereby blocking the replication of the Varicella-Zoster Virus (VZV). Mecobalamin, a coenzyme form of Vitamin B12, is utilized as a neuroprotective agent to promote nerve repair and alleviate neuropathic pain, such as postherpetic neuralgia, which is a common complication of herpes zoster. This specific combination is being evaluated by the First People's Hospital of Hangzhou in clinical studies to investigate its immunomodulatory effects and therapeutic outcomes when administered alongside electroacupuncture in patients with herpes zoster.
