HIV medications

Classes

Class	Examples	Mechanism of Action	Adverse Effects
Nucleoside reverse-transcriptase inhibitor (NRTI)	tenofovir, emtricitabine, abacavir	Nucleoside/nucleotide analogues that get incorporated into viral DNA by reverse transcriptase, causing missense or non-sense mutations. The backbone of HIV treatments, with a high barrier to resistance.
Non-nucleoside reverse-transcriptase inhibitor (NNRTI)	efavirenz	Actively inhibit reverse transcriptase at its active site. Resistance develops with a single point mutation.
Protease inhibitor (PI)	dirunavir	Inhibits protease, which is required for processing proteins in the creation of the virion.	Metabolic syndrome
Integrase strand transfer inhibitor (INSTI)	raltegravir, dolutegravir, bictegravir		Generally very well-tolerated; may cause weight gain and diabetes
Fusion inhibitor
CCR5 entry inhibitor	maraviroc	Blocks entry of HIV into CD4 cells.
CD4-mAb	ibalizumab
