Abstract: Let $k$ be a perfect field, $H$ a irreducible cocommutative Hopf $k$-algebra and $P(H)$ the space of primitive elements of $H$, $R$ a $k$-algebra on which acts locally finitely $H$ and $R\#H$ the associated smash product. Assume that $H$ is almost solvable with $P(H)$ finite-dimensional $n$ and the sequences of divided powers are all infinite. Then the Gelfand-Kirillov dimension of $R\#H$ is $GK(R)+n$.
