It is shown that at collider energies experimental distributions in the multiplicity n of negatively charged particles in inelastic and nonsingle diffractive pp collisions are well parametrized by a sum of so-called Gupta-Sarma distributions having the Poisson distribution as a particular case. This extends the earlier description of the multiplicity distributions in hadron-hadron collisions at c.m. energies below 65 GeV by the two parameter sum of Poissonian distributions. Implications of the proposed parametrization for the CERN LHC energy are discussed.
