• 정의

  ChEBI: Tenofovir alafenamide fumarate is a fumarate salt prepared from tenofovir alafenamide by reaction of one molecule of fumaric acid for every two molecules of tenofovir alafenamide. A prodrug for tenofovir, it is used in combination therapy for the treatment of HIV-1 infection. It has a role as an antiviral drug, a HIV-1 reverse transcriptase inhibitor and a prodrug. It contains a tenofovir alafenamide(1+).

• Drug interactions

  Some products that may interact with this drug are: adefovir, orlistat, other drugs that may harm the kidneys (including aminoglycosides such as amikacin/gentamicin).

• Advantages

  One major advantage of the hemifumarate form of tenofovir alafenamide over the monofumarate form is its exceptional capability to purge GS-7339 (i.e., 9-[(R)-2-[[(R)-[[(S)-1-(isopropoxycarbonyl)ethyl]amino]phenoxyphosphinyl]methoxy]propyl]adenine, which is the major diastereomeric impurity in the active pharmaceutical ingredient. Thus, the hemifumarate form of tenofovir alafenamide can be more readily and easily separated from impurities than the monofumarate form. Other major advantages of tenofovir alafenamide hemifumarate over the monofumarate form include improved thermodynamic and chemical stability (including long-term storage stability), superior process reproducibility, superior drug product content uniformity, and a higher melting point.
