High energy inclusive hadron production in the central kinematical region is analyzed within the models of unitarized pomeron. It is shown that the sum of multipomeron exchanges with intercept αP(0)>1 reproduce qualitatively contribution of the triple pole (at t=0) pomeron to inclusive cross section. Basing on this analogy we then suggest a general form of unitarized pomeron contributions (in particular the dipole or tripole pomeron) to inclusive cross section. They lead to a parabolic form of the rapidity distribution giving <n>∝ ln3s (tripole) or <n>∝ ln2s (dipole). The models considered with suggested parametrization of pt-dependence for cross sections well describe the rapidity distributions data in pp and pp interactions at energy √(s)≥ 200 GeV. The predictions for one particle inclusive production at LHC energies are given.
