Emtricitabine based drugs: price, availability and description

Emtricitabine is a nucleoside reverse transcriptase inhibitor (NRTI) used for the treatment and prevention of HIV infection. It works by blocking the viral enzyme required for replication. The drug is almost always prescribed in combination with other antiretrovirals (most commonly tenofovir) as part of combination antiretroviral therapy (cART). Emtricitabine is also widely used for pre-exposure prophylaxis (PrEP) to prevent HIV acquisition.
