Efavirenz is one of the most recent classes of anti-retroviral drugs used in the treatment of HIV infections. It is the first choice therapy for AIDS treatment. As efavirenz detains hydrofobic characteristic, low density and offers great resistance to draining, it has been essential to choose an adequated formulation for it, in order to guarantee drug's availability in gastro-intestinal tract, achieving bioavailability and expected therapeutical effects. This work presents efavirez coated tablets thecnological development, considering the physics and physico-chemical characteristics of this drug. The efavirez nucleus (tablets) has been obtained employing granulation technics by humid via. In the coating by film, Opadry Y-1-7000 in aquous system was used. The adopted parameters to tablet phisics evaluation followed official phamacopeial specifications and quantitative determination of the drug was performed by developed and validated methodology.
