WHAT IS TENVIR ?
Tenvir 300mg is an antiviral drug belonging to class nucleoside reverse transcriptase inhibitors (NRTIs). Its structure closely resembles the natural structure of viral DNA, that helps it to incorporate itself into the viral DNA. By doing so, it blocks the activity of an important viral enzyme reverse transcriptase which is involved in the replication of viral DNA, a process essential for survival of the virus.
