Trioday is a combination medicine used to treat HIV infection.
It contains three medicines in one tablet:

• Tenofovir disoproxil fumarate (TDF)

• Lamivudine (3TC)

• Efavirenz (EFV)

This single pill helps control HIV more easily.

Mechanism 

• Tenofovir & Lamivudine: Block the HIV enzyme reverse transcriptase (NRTIs – nucleoside/nucleotide reverse transcriptase inhibitors).

• Efavirenz: Blocks the same enzyme but in a different way (NNRTI – non-nucleoside reverse transcriptase inhibitor).

• Together, they stop the virus from making new copies of itself.

• This reduces the HIV level in the blood and helps the immune system become stronger.

  Uses

  • Treatment of HIV-1 infection in adults and adolescents.

  • Helps prevent HIV complications and improves quality of life.
