Mechanism of action
Zepdon is an Integrase strand transfer inhibitor effective against human immunodeficiency virus type I infection.
Raltegravir prohibit the catalytic activity of Integrase, an HIV-encoded enzyme, responsible for viral replication.
Incorporation of HIV chromosomes into the host cell genomes will be inhibited This leads to depletion in the production of new infectious viral particles.

Raltegravir is largely bound to the human plasma protein with 83%
The metabolism of the Raltegravir occurs majorly in liver with the help of UGT1A1. The drug is metabolized away through Glucuronidation
The metabolites are excreted through feces and urine. The terminal half life of the drug is 9 hours
