Fostemsavir Brand Name– Rukobia
What is Fostemsavir
Fostemsavir is indicated for use in combination with other antiretroviral agents to treat heavily treatment-experienced adults with multidrug-resistant HIV-1 infections who are failing their current antiretroviral regimen due to resistance, intolerance, or safety considerations.
Fostemsavir is the first approved HIV-1 attachment inhibitor, which works by binding to the glycoprotein 120 (gp120) subunit within the HIV-1 envelope and selectively inhibiting the interaction between the virus and cellular CD4 receptors.
Health care providers are advised to consider potential drug interactions prior to and during treatment with fostemsavir because the drug is partially metabolized by CYP3A4 and supratherapeutic doses have been associated with prolongation of the QT interval.
