The prevalence of transmitted drug resistance has been stable for the last years with only minor variation. 0000041801 00000 n The basic principles of management of antiviral resistance are to change therapy early once virological breakthrough is observed, select an add-on approach over switching, and choose rescue therapy based on the cross-resistance profile and potency of the rescue drug and presence of comorbid conditions. For example, enfuvirtide (Fuzeon, T20, DP178), a 36-amino acid peptide that inhibits human immunodeficiency virus type 1 (HIV-1) infection by effectively targeting the viral fusion apparatus, has been relegated to a salvage treatment option … While many volumes have been written about various aspects of antimicrobial resistance, this book is a comprehensive reference work. As such this unique volume will be essential to basic researchers in drug discovery and viral pathogenesis, as well as clinicians involved in antiviral chemotherapy.
