Annotation: We consider the description for the inflationary universe produced by viscous fluid in a flat Friedmann-Lemaitre-Robertson-Walker geometry. We have obtained the conditions of the existence regime of the inflation without selfreproduction for the theoretical inflationary model which agree with last results of the Planck satellite data.

Keywords: inflation, equation of state, viscosity, spectral index, tensor-to-scalar ratio
