Efavirenz based drugs: price, availability and description

Efavirenz is an antiretroviral medication from the non-nucleoside reverse transcriptase inhibitor (NNRTI) class. It is used to treat HIV-1 infection in adults and children (usually over 3 years of age). Efavirenz blocks the viral enzyme required for replication, thereby reducing viral load and boosting the immune system. The drug is always prescribed in combination with other ARV agents (often as part of the fixed-dose combination Atripla).
