Inosine pranobex

Inosine pranobex (BAN; also known as inosine acedoben dimepranol (INN) or methisoprinol) is an antiviral drug that is a combination of inosine and dimepranol acedoben (a salt of acetamidobenzoic acid and dimethylaminoisopropanol) in a ratio of 1 to 3. Inosine pranobex has no effect on viral particles itself. Instead, it acts as an immunostimulant, an analog of thymus hormones. It is most commonly used to treat the rare measles complication subacute sclerosing panencephalitis in conjunction with intrathecal interferon therapy.
In the UK, inosine pranobex is also indicated for mucocutaneous infections due to herpes simplex virus (type 1 and type 2) and for treatment of genital warts as adjunctive therapy to podophyllotoxin or carbon dioxide laser.
