Isoprinosine 500mg Tablet, marketed as ISOJOL, contains inosine pranobex 500mg, an antiviral and immunomodulatory medicine. Inosine pranobex is also known as isoprinosine, inosine acedoben dimepranol, methisoprinol, and inosine pranobex. The medicine has been used in different countries for selected viral infections and specific clinical conditions, with approved indications varying by market.
