What is Sitavig?

Sitavig is an antiviral drug. It slows the growth and spread of the herpes virus in the body. Acyclovir will not cure herpes, but it can lessen the symptoms of the infection.

Sitavig a buccal tablet (dissolved under the tongue) used to treat cold sores on the lips. Sitavig will not treat genital herpes.

Based on proprietary Lauriad technology, Sitavig comes in the form of a mucoadhesive tablet which the patient places on the gum and which delivers a high concentration of acyclovir directly to the lip, the site of the cold sore infection. In a phase III international study conducted on 775 patients, Sitavig demonstrated a high level of efficacy in terms of healing time with one single tablet containing 50 mg of acyclovir and an excellent tolerance profile. In addition to its efficacy, Sitavig offers a unique unobtrusive and simple formulation with a single application for the episode's entire duration, representing major advantages for patients suffering from recurrent herpes sores.
