As a general rule, HIV regimens consist of [+]
What is the BHIVA recommendation drug regimens to start for HIV tx? [4]
As a general rule, regimens consist of:
Two nucleoside reverse transcriptase inhibitors (NRTIs)
A third agent, typically one of:
- Ritonavir-boosted protease inhibitor (PI/r)
- Non-nucleoside reverse transcriptase inhibitor (NNRTI)
- Integrase inhibitor (INI) - RECOMENDED
OR
- Dolutegravir + Lamivudine
This is the list of BHIVA preffered drug regimens to start
In theory; any of above can be used; but BHIVA slide is the.
Name examples for NRTIs [4] and NNRTIs [2]
NRTIs:
* Tenofovir disoproxil fumarate
* Abacavir
* Emtricitabine
* Lamivudine
NNRTIs:
- Efavirenz
- Nevirapine
As NRTIs are the backbone - don’t want to be LATE with starting treatment Lamivudine, Abacavir TDF Emtricitabine
Describe the MoA of PIs [1]
Protease inhibitors (PIs) inhibit the action of protease preventing the cleavage of Gag-Pol polyproteins.
PIs are given alongside which drug [1] as they boost the action of the drug
Name two examples of PIs
They are given alongside ritonavir - referred to as a boosted PI - which increase the action of the drug.
PIs:
* Atazanavir
* Darunavir
* Lopinavir
[] tend to have a high barrier to resistance and therefore may be preferred in patients where there are concerns regarding adherence
NRTIs
NNRTIS

Post-attachment inhibitors prevent envelope protein [] engaging with co-receptors.
Name an example [1]
Post-attachment inhibitors prevent envelope protein glycoprotein-120 engaging with co-receptors.
There is currently one medication in this class, the monoclonal antibody Ibalizumab. It is given as an IV infusion once every two weeks.
Which drugs are contained in PEP? [2]
For how long is the course? [1]
Once a day of:
* Tenofovir disoproxil fumerate
* Two Raltegravir
for 28 days
State 3 side effects of protease inhibitors [3]
There are many adverse effects including lipodystrophy, hyperlipidaemia, insulin resistance and hepatotoxicity.
Which drugs are used in PrEP? [1]
Tenofovir-df/emtricitabine
How do you measure safety and toxicity of ARTs? [3]
- Renal and liver test
- Lipids and metabolic tests
- FBCs
Which ART might cause this reaction
Abacavir
Efavirenz
Tenofovir
Darunavir
Nevirapine
Which ART might cause this reaction
Abacavir - get HLAB5701 screen
Efavirenz
Tenofovir
Darunavir
Nevirapine
Which two drugs make up long-acting drugs for HIV treatment? [2]
II and NNRTI
Name two side effects of Tenofovir DF long term use [2]
Tenofovir DF:
- Tubular toxicity (prevents re-ab of certain solutes at PCT - risk of kidney failure
- Reduction in bone mineral density
Name a side effect of abacavir long term use [1]
Dyslipidaemia / atherosclerosis
Avoid in ptx with high risk CVD
