Additional Information
Uses for Emtricitabine and Tenofovir Alafenamide Fumarate
Emtricitabine and Tenofovir Alafenamide Fumarate (FTC/TAF) serves multiple functions in HIV management and pre-exposure prophylaxis (PrEP). It is used in combination with other antiretrovirals for treating HIV-1 infection and as a standalone regimen for PrEP.
Treatment of HIV Infection
FTC/TAF is utilized for treating HIV-1 infection in adults, adolescents, and pediatric patients weighing ≥35 kg.
- Adults and Adolescents: Must be used in conjunction with other antiretrovirals.
- Pediatric Patients: For those weighing between 14 kg and <35 kg, it is used excluding protease inhibitors that require a CYP3A inhibitor.
In its dual NRTI form, this drug is integral to various treatment regimens:
- In conjunction with an HIV integrase strand transfer inhibitor (INSTI).
- Paired with a non-nucleoside reverse transcriptase inhibitor (NNRTI).
- Inclusion in HIV protease inhibitor (PI)-based regimens.
For initial therapy in antiretroviral-naive adults and adolescents, FTC/TAF is recommended by experts for use in most INSTI-, NNRTI-, and PI-based regimens. Similar guidance applies to pediatric patients, with specific dosage recommendations for different weight categories.
Preexposure Prophylaxis for Prevention of HIV-1 Infection (PrEP)
FTC/TAF is prescribed for PrEP to reduce the risk of sexually acquired HIV-1 in at-risk HIV-1-negative adults and adolescents weighing ≥35 kg. Such individuals must undergo an HIV-1 test immediately before starting FTC/TAF for PrEP, and periodic testing every three months during PrEP. The efficacy of this drug in individuals at risk from receptive vaginal sex has not been established.
In addition to the medication, a complete prevention strategy, including safer sex practices, is recommended for PrEP.
| Population | Indications | Special Instructions |
|---|---|---|
| Adults and adolescents weighing ≥35 kg | Post-exposure prophylaxis for at-risk HIV-1-negative individuals | Regular HIV-1 testing every 3 months |
| Adults weighing <35 kg | Not recommended | No established efficacy |
Dosage and Administration
The dosage for FTC/TAF varies based on the population and the purpose of use (treatment or PrEP). Administered once daily without regard to food, it needs adjustment for various conditions, including renal and hepatic impairments.
General Pretreatment Screening
- Test for hepatitis B virus (HBV) infection.
- Assess serum creatinine, estimated creatinine clearance (Clcr), urine glucose, and urine protein.
- Screen for HIV-1 infection before initiating FTC/TAF for PrEP.
Specific Dosage Information
- Adults (for HIV-1 treatment): 1 tablet (FTC 200 mg + TAF 25 mg) once daily.
- Adults (for PrEP): 1 tablet (FTC 200 mg + TAF 25 mg) once daily.
- Pediatric Patients: Dosage varies based on weight. Refer to the dosages listed in the table below.
| Weight (kg) | Dosage of Emtricitabine/Tenofovir Alafenamide |
|---|---|
| 14 to <25 kg | 1 tablet (emtricitabine 120 mg + tenofovir alafenamide 15 mg) |
| 25 to <35 kg | 1 tablet (emtricitabine 200 mg + tenofovir alafenamide 25 mg) |
| ≥35 kg | 1 tablet (emtricitabine 200 mg + tenofovir alafenamide 25 mg) |
Considerations for Special Populations
Dosage adjustments are necessary for patients with renal and hepatic impairments:
- Renal Impairment: Use usual dosage for patients with Clcr ≥30 mL/min. No dosage adjustment required for adults receiving hemodialysis.
- Hepatic Impairment: Use usual dosage for mild or moderate impairment; not studied for severe impairment.
Administration
Administer FTC/TAF orally once daily, with or without food. For HIV-1 treatment, FTC/TAF must be used in combination with other antiretrovirals. For PrEP, it can be used as a complete regimen alone.
Drug Interactions
FTC/TAF may have interactions with several drug types, notably those affecting the kidneys and drugs that affect P-glycoprotein (P-gp) transport and breast cancer resistance protein (BCRP).
Drugs Affecting or Metabolized by Hepatic Microsomal Enzymes
FTC is not a substrate of CYP isoenzymes and has no significant interactions with these enzymes. TAF is minimally metabolized by CYP3A.
- Antimycobacterial agents: Rifampin decreases tenofovir concentrations; concomitant use not recommended.
- Anticonvulsant agents: Carbamazepine and phenytoin decrease tenofovir concentrations; alternative anticonvulsants should be considered.
- Nephrotoxic drugs: Avoid co-administration, which can increase concentrations of FTC/TAF and exacerbate renal-related side effects.
| Drug Class | Potential Interaction | Recommendation |
|---|---|---|
| Aminoglycosides | Potential increase in concentrations of FTC/TAF | Avoid in patients receiving nephrotoxic drugs |
| Anti-mycobacterial agents | Decreased tenofovir concentrations | Concomitant use not recommended |
| NSAIAs | Potential increase in concentrations of FTC/TAF | Avoid in patients receiving nephrotoxic drugs |
Patient Monitoring and Considerations
Consistent monitoring is crucial for patients on FTC/TAF, particularly for those with potential HBV co-infection and those on PrEP.
- Monitor hepatic function closely post-discontinuation in HBV-infected patients.
- Assess renal function routinely, including serum creatinine and urine protein.
- Screen for HIV-1 infection at least every 3 months in PrEP patients.
Renal Function and Monitoring
- Measure serum creatinine, Clcr, urine glucose, and protein before starting FTC/TAF.
- For patients with chronic kidney disease, monitor serum phosphorus.
Adherence to Dosage and Scheduled Screenings
Emphasize to patients the importance of adhering to the prescribed dosage schedule and attending regular follow-up appointments for screenings.
Advice to Patients
Patients should be adequately informed about the critical aspects of their treatment, including compliance, safety practices, and necessary screenings.
- Read FDA-approved patient labeling.
- Strict adherence to prescribed therapy, particularly for PrEP.
- Continue practicing safer sex to mitigate the risk of HIV transmission.
With rigorous adherence and medical supervision, FTC/TAF serves as a versatile component in both the treatment and prevention of HIV-1 infection. Regular monitoring, patient education, and adherence to guidelines enhance the drug’s efficacy and safety profile.
