Drug Dosing Toolkit

Combivir (AZT + Epivir)

Type of Drug: Fixed-Dose Combination

Fixed-dose combinations combine the most commonly prescribed doses of several medications into 1 pill. This pill is a combination of drugs known as nucleoside reverse transcriptase inhibitors, also called NRTIs, nucleoside analogues, or "nukes." These were the first type of drug available to treat HIV.

When the HIV virus enters a healthy cell, it attempts to make copies of itself. It does this by using an enzyme called reverse transcriptase. NRTIs block that enzyme, so HIV cannot make new copies of itself.
