It is manufactured by Bristol-Myers Squibb. T is also known as stavudine or didehydro-deoxythymidine.
T is a nucleoside analog reverse transcriptase inhibitor, or nuke.
These drugs block the reverse transcriptase enzyme. This has to occur before HIV's genetic code gets inserted into an infected cell's own genetic codes. T was approved as an antiviral drug for people with HIV infection. Pregnant women should not take d4T and ddI at the same time. There are no absolute rules about when to start antiviral drugs.
