Trilavir L Tablet (Lamivudine 300mg + Tenofovir disoproxil fumarate 300mg + Efavirenz 600mg) – Overview

Trilavir L Tablet Contains Lamivudine (300mg), Tenofovir disoproxil fumarate (300mg), and Efavirenz (600mg) are components of a combination antiretroviral therapy (cART) used to treat HIV-1 infection in adults and children over a certain age. This combination works synergistically to suppress viral replication and improve immune function in individuals with HIV.

Medical Uses / Indications

This medication is indicated for the treatment of HIV-1 infection and is typically used in combination with other antiretroviral agents. It is not a cure for HIV but helps manage the virus and reduce the likelihood of transmission.

How Trilavir L tablet Works (Mechanism of Action)

Lamivudine: A nucleoside reverse transcriptase inhibitor (NRTI) that is incorporated into the viral DNA, preventing the reverse transcription process and halting viral replication.

Tenofovir Disoproxil Fumarate: Also an NRTI that inhibits reverse transcriptase, leading to the termination of the viral DNA chain during replication.

Efavirenz: A non-nucleoside reverse transcriptase inhibitor (NNRTI) that binds directly to reverse transcriptase, altering its shape and function, which prevents the replication of the virus.

Dosage & Administration

The recommended dosage is one tablet taken orally once daily, ideally at the same time each day. It can be taken with or without food, although taking it with food may help minimize gastrointestinal side effects. Prescribing physicians should adjust the dosage based on individual patient profiles and other factors.
