Pharmacology of Myhep Lvir
Mechanism of action
MyHep LVIR (ledipasvir) is a HCV NS5A polymerase inhibitor, which is mainly required for viral multiplication. Ledipasvir mode of action targets NS5A protein which used for resistance selection in cell culture and cross-resistance studies.
Sofosbuvir(MyHep LVIR) is a hepatitis C virus NS5B RNA dependent and polymerase that used for viral reproduction. A nucleotide prodrug (Sofosbuvir) which undergoes intracellular metabolism to form uridine analog triphosphate. It will inhibit the viral replication and blocks the new production of HCV. Sofosbuvir (MyHep LVIR) acts as chain terminator by NS5B polymerase.
Absorption: MyHep LVIR ( ledispavir/Sofosbuvir) and predominant circulating metabolite (GS-331007) have been subjected to healthy adult with chronic hepatitis C.
Median Peak Plasma Concentration(MPPC)
DRUGS RANGE(hrs post dose)
Sofosbuvir 0.8-1(absorbed quickly)
Effect with food: For fasting conditions- Single dose of MyHep LVIR
administration with moderate fat or high fat meal increased Sofosbuvir have no significant effect. Therefore MyHep LVIR response rate was equal in phase trials and HCV infected patient can administrated with or without food.

Metabolism: MyHep LVIR (Ledipasvir) metabolism was observed by human is CYP1A2,CYP2C8,CYP2C9,CYP2C19,CYP2D6,CYP3A4
Extensively Sofosbuvir ( MyHep LVIR ) metabolized in the Hepato (liver) in which it form pharmacologically active nucleoside analog triphosphate GS-461203
