Generic medicines in Brazil are now reality and at hand to a large segment of the population. However, the reliability of generic medicines requires a rigid control over all phases of production. The starting point is an appropriate study of equivalence to a brand name product. A study covering all phases - clinical, analytical and, finally, statistical - is also fundamental in the process. Mediana Consultoria  works in the area of generic and similar medicines, providing support throughout all phases, from experimental design for bioequivalence studies to complete statistical data analyses.
