  The purpose of the present paper is to find the necessary and sufficient
conditions for the subclasses of analytic functions associated with Pascal
distribution to be in subclasses of spiral-like univalent functions and
inclusion relations for such subclasses in the open unit disk $\mathbb{D}.$
Further, we consider the properties of integral operator related to Pascal
distribution series. Several corollaries and consequences of the main results
are also considered.
