Emtricitabine: Emtricitabine is a nucleoside reverse transcriptase inhibitor (NRTI) that also inhibits HIV replication.
Pharmacological Properties:
These medications act by targeting key enzymes involved in the HIV replication cycle, thereby preventing the virus from multiplying in the body. They are well-absorbed after oral administration and reach therapeutic concentrations in the blood.
Indications:
Efavirenz and emtricitabine are indicated for the treatment of HIV-1 infection in adults and children above a certain age and weight.
