In the present paper we study the operator defined by using the extended Ruscheweyh derivative
and the extended generalized S\u{a}l\u{a}gean operator
, as
,
where
\ is the class of normalized analytic functions with
We obtain several strong differential subordinations regarding the extended operator
. Some examples are presented.
