We expand the study of the pseudoscalar glueball and its first excited stateby constructing an interaction Lagrangian which produces the two- andthree-body decays of the pseudoscalar glueball, $J^{PC}=0^{-+}$, into the(pseudo)scalar and the excited (pseudo)scalar mesons as well as by constructingother two different chiral Lagrangians which describe the two- and three-bodydecays of the first excited pseudoscalar glueball, $J^{PC}=0^{*-+}$, into the(pseudo)scalar and the excited (pseudo)scalar mesons. We compute the decaychannels for the ground state of a pseudoscalar glueball with a mass of $2.6$GeV and for the first excited pseudoscalar glueball with a mass $3.7$ GeV,following predictions from Lattice QCD in the quenched approximation. Thesestates and channels are within reach of PANDA experiment at the upcoming FAIRfacility experiment and ongoing BESIII experiment. In our approach, the variousbranching ratios are a parameter-free prediction.
