Ledipasvir is an inhibitor of the hepatitis C virus NS5A, with EC50 values of 34 pM against GT1a and ledipasvir mrm transitions 4 pM against GT1b replicon. The detection was performed on a triple quadrupole tandem mass spectrometer by multiple reaction monitoring(MRM) mode to monitor the precursor-toproduct ion transitions of m/z 889.

1azabicyclic ring system was discovered. While its mechanism of action is unclear, mutations that confer resistance to ledipasvir in HCV replicon cells are located in NS5A, suggesting that NS5A is the direct target of ledipasvir. As with Sofosbuvir, the cost of Harvoni was a controversial topic. However, given the high rate. Although not all of these side effects may occur, if they do occur they may need medical attention.
