Description of Myhep All
Myhep All is a combination medicine, contains an active ingredients like Sofosbuvir and Velpatasvir, both having anti-viral properties.
Myhep All is active against virus which is responsible for chronic hepatitis C viral infection.
Myhep All is a prescription medicine; it is used by the patient under the supervision of medical practitioner.
Sofosbuvir: HCV NS5B polymerase inhibitor
Velpatasvir: HCV NS5A inhibitor
Trade name: Myhep All
Active ingredients: Sofosbuvir and Velpatasvir
Strength of the drug: 400mg and 100mg respectively
Package: 28 tablets in a container
Pharmacology of Myhep All
Myhep All Mechanism of action:
Myhep All containing two ingredients which exhibits antiviral activity,
Sofosbuvir: a nonstructural protein 5B polymerase inhibitor, essential for viral multiplication.
Sofosbuvir is a prodrug (nucleotide analog), metabolized into active form called uridine analogue triphosphate (GS-461203)
The metabolite GS-461203 is integrated into hepatitis C virus RNA by NS5B polymerase and performed as a chain terminator.
Velpatasvir: NS5A protein is responsible for RNA replication and aggregation of HCV virions.
Velpatasvir is a NS5A inhibitor which interfere with the enzyme activity and eradicates the viral multiply
Myhep All Pharmacokinetics:
After oral administration of Myhep All tablet, absorption occurs very quickly.
The peak plasma concentration of the Sofosbuvir, Velpatasvir and GS-461203 (active metabolite) occurs within 1 hour, 3 hours and 3 hours respectively.
Effect of food:
The response rate of both Sofosbuvir and Velpatasvir are similar to each other while taking with or without food.
Sofosbuvir is bound to human plasma protein in the range of 61-65%
Velpatasvir is highly bound to plasma protein around >99.5%
The active metabolite GS-461203 has poor protein binding property
Sofosbuvir is largely metabolized in liver, converted to active analogue triphosphate GS-461203
Velpatasvir is eliminated greatly in unchanged form
80%, 14%, and 2.5% of the drug is eliminated through urine, faeces and exhaled air respectively.
The terminal half life of Tablet Myhep All is 15 hours.
