'''Fosamprenavir''' ('''FPV'''), sold under the brand names '''Lexiva''' and '''Telzir''', is a [[medication]] used to treat [[HIV/AIDS]].<ref name="Lexiva FDA label" /><ref name="Telzir EPAR" /> It is a [[prodrug]] of the [[protease inhibitor (pharmacology)|protease inhibitor]] and [[antiretroviral drug]] [[amprenavir]].<ref>{{Cite web |url=https://www.drugs.com/monograph/fosamprenavir.html |title=Fosamprenavir Monograph for Professionals |access-date=2022-10-03 |archive-date=2021-06-28 |archive-url=https://web.archive.org/web/20210628020421/https://www.drugs.com/monograph/fosamprenavir.html |url-status=live }}</ref> It is marketed by [[ViiV Healthcare]] as the [[calcium]] salt.<ref name="Lexiva FDA label" /><ref name="Telzir EPAR" /> |
|||
Fosamprenavir was approved for medical use in the United States in October 2003,<ref>{{cite web | title=Drug Approval Package: Lexiva (Fosamprenavir Calcium) NDA #021548 | website=U.S. [[Food and Drug Administration]] (FDA) | url=https://www.accessdata.fda.gov/drugsatfda_docs/nda/2003/21-548_Lexiva.cfm | access-date=2 October 2022 | archive-date=15 April 2021 | archive-url=https://web.archive.org/web/20210415193225/https://www.accessdata.fda.gov/drugsatfda_docs/nda/2003/21-548_Lexiva.cfm | url-status=live }}</ref> and in the European Union in July 2004.<ref name="Telzir EPAR" /> The human body metabolizes fosamprenavir in order to form amprenavir, which is the active ingredient.<ref name="Lexiva FDA label" /> |
|||
A head-to-head study with [[lopinavir]] showed the two drugs to have comparable potency, but patients on fosamprenavir tended to have a higher serum cholesterol.<ref>{{cite journal | vauthors = Eron J, Yeni P, Gathe J, Estrada V, DeJesus E, Staszewski S, Lackey P, Katlama C, Young B, Yau L, Sutherland-Phillips D, Wannamaker P, Vavro C, Patel L, Yeo J, Shaefer M | display-authors = 6 | title = The KLEAN study of fosamprenavir-ritonavir versus lopinavir-ritonavir, each in combination with abacavir-lamivudine, for initial treatment of HIV infection over 48 weeks: a randomised non-inferiority trial | journal = Lancet | volume = 368 | issue = 9534 | pages = 476–82 | date = August 2006 | pmid = 16890834 | doi = 10.1016/S0140-6736(06)69155-1 | s2cid = 33612672 }}</ref> |
|||
==Medical uses== |
|||
Fosamprenavir is used for the treatment of [[HIV-1]] infections, typically but not necessarily in combination with low-dose [[ritonavir]] or other antiviral drugs.<ref name="Austria-Codex">{{cite book|title=Austria-Codex| veditors = Jasek W |publisher=Österreichischer Apothekerverlag|location=Vienna|year=2007|edition=62nd|isbn=978-3-85200-181-4|pages=8009–17|language=German}}</ref><ref>{{cite report | work = [[Drugs.com]] | title = Lexiva | id = {{drugs.com|monograph|lexiva}}}}</ref> |
|||
==Adverse effects== |
|||
The most common adverse effect is diarrhea. Other common side effects include [[headache]], dizziness and exanthema, which is usually transient. Severe allergic reactions ([[Stevens–Johnson syndrome]]) are rare.<ref name="Austria-Codex" /> |
|||
== Interactions == |
|||
Amprenavir (the active metabolite of fosamrenavir, which is found in blood plasma, liver and other organs) is metabolized via the liver enzyme [[CYP3A4]] and also weakly inhibits this enzyme. This means that combination with drugs that are also metabolized by CYP3A4 can increase their plasma concentrations and thus side effects; and combination with drugs that inhibit CYP3A4 can increase amprenavir concentrations.<ref name="Austria-Codex" /> |
|||
When combining fosamprenavir with low doses of the CYP3A4 inhibitor ritonavir, this interaction is intended as it allows for application of lower fosamprenavir doses.<ref name="Austria-Codex" /> |
|||
==Pharmacology== |
|||
Fosamprenavir is quickly activated to amprenavir, even before it reaches the circulation. Amprenavir is a HIV [[protease inhibitor (pharmacology)|protease inhibitor]].<ref name="Austria-Codex" /> |
