Trustiva (Tenofovir / Efavirenz / Emtricitabine)
Trustiva is a fixed-dose combination antiretroviral medication (3-in-1).
Manufacturer: Hetero Healthcare (India). Trustiva is a generic version of the brand-name drug Atripla.
Mechanism of Action ("Triple Strike"):
It combines three active ingredients in a single pill: Efavirenz (NNRTI), Emtricitabine (NRTI), and Tenofovir (NtRTI). Together, they act synergistically to block the HIV reverse transcriptase enzyme. This prevents the virus from replicating its genetic material, effectively halting the spread of infection within the body.
✅ Key Benefit: Complete once-daily regimen in a single tablet, simplifying therapy and improving adherence.
Indicated for the treatment of:
- 🦠 HIV-1 Infection: In adults and adolescents (weighing >40 kg) with virologic suppression or who are treatment-naive.
- It replaces the need for taking multiple pills from different bottles.
Packaging: Bottle of 30 Tablets.
⚠️ ADMINISTRATION PROTOCOL:
- 💊 Standard Dose: One tablet once daily.
- 🍽️ EMPTY STOMACH: Taking Trustiva with food (especially high-fat meals) increases Efavirenz absorption to toxic levels. Avoid food 2 hours before and 1 hour after dosing.
- 🛌 Timing: It is strongly recommended to take the tablet at bedtime to minimize central nervous system (CNS) side effects like dizziness.
- Severe hepatic impairment (Liver failure).
- Severe renal impairment.
- Pregnancy (potential risk of birth defects) and breastfeeding.

- 🤯 CNS Symptoms: Dizziness, vivid dreams or nightmares, insomnia, and impaired concentration (due to Efavirenz).
- 🔴 Skin: Mild rash is common during the first weeks.
- ⚠️ Kidneys: Potential renal toxicity; monitoring is advised.
