This creates a nitrate-free period and minimizes tolerance to. With an overall half-life of about 5 hours the 5-mononitrate is cleared from the serum by denitration to isosorbide glucuronidation to the 5-mononitrate glucuronide and denitrationhydration to sorbitol. The 2-mononitrate has been less well studied but it appears to participate in the same metabolic pathways with a half-life of about 2 hours.
