We study the Color-flavor locked (CFL) superconducting phase in the context of quark mass density dependent model (QMDDM) considering three parametrizations of the effective quarks mass. For the thermodynamic consistence of the model, we introduce an effective contribution to the pressure of the system due to the quark dynamic masses. Within this context, we analyze the stability of the QMDDM+CFL phase and compare with the case in which the quark masses are independent of the baryonic density (set as Parametrization 1).
