The problem of computing the Drazin inverse of a \(2\times2\) block matrix is a difficult open problem in the general case. In this paper, a special kind of these block matrices is analized extending some results given by \textit{N. Castro-Gonzalez} and \textit{E. Dopazo} [Linear Algebra Appl. 400, 253--269 (2005; Zbl 1076.15007)].
