Tenofovir disoproxil is also known as Viread (trade name). It is a medication that is used for treating hepatitis B and HIV (human immunodeficiency virus) /AIDS (acquired immunodeficiency syndrome) also. It is recommended to use with other antiretrovirals. Tenofovir disoproxil is an NtRTI (nucleotide analog reverse-transcriptase inhibitor).
It lacks hydroxyl group on itscarbon and thus, prevents elongation of DNA (deoxyribonucleic acid) chain. It leads to termination of transcription and hence, viral replication.
Adefovir is a medication given to treat infections like hepatitis B. Its trade name is Preveon as well as Hepsera. It is administered orally and is administered as a pivoxil adefovir dipivoxil. It works via blocking the enzyme reverse transcriptase activity.
Hepatitis is a chronic or acute inflammation of the liver, which is caused by a hepatotoxic drug or a viral infection. Hepatitis, when caused by an infection is contagious and can be transmitted by contact with blood or sexual intercourse.
