BIC = bictegravir

DRV = darunavir

DTG = dolutegravir

F/TAF = FTC/TAF = Emtricitabine/Tenofovir alafenamide

F/TDF = FTC/TDF = Emtricitabine/Tenofovir disoproxil fumarate

B/F/TAF = BIC/FTC/TAF = Bictegravir/Emtricitabine/Tenofovir alafenamide (single tablet regimen)

DTG/ABC/3TC = Dolutegravir/Abacavir/Lamivudine (single tablet regimen)

DTG + F/TAF = DTG + FTC/TAF = Dolutegravir + Emtricitabine/Tenofovir alafenamide (multi-tablet regimen)

D/C/F/TAF = DRV/COBI/FTC/TAF = Darunavir/Cobicistat/Emtricitabine/Tenofovir alafenamide (single tablet regimen)

DTG/3TC = Dolutegravir/Lamivudine (single tablet regimen)

CAB = Cabotegravir

CAB + RPV = Cabotegravir + Rilpivirine

Video content above is prompted by the following questions:

Integrase inhibitors like dolutegravir and bictegravir bind to the active site of the integrase and as such suppress the HIV virus; they are integral to modern therapeutic algorithms.
- Can you explain the differences in binding affinity between dolutegravir and bictegravir and does this impact your treatment selection?
