We prove the existence of at least one positive solution for a Schrödinger equation in
 $\mathbb{R}^N$
of type
 $- \Delta u + V(x) u = f(x, u) \ \ \text{in} \ \mathbb{R}^N$
with a vanishing potential at infinity and subcritical nonlinearity
 $f$
. Our hypotheses allow us to consider examples of nonlinearities which do not verify the Ambrosetti-Rabinowitz condition, neither monotonicity conditions for the function
 $\frac{f(x, s)}{s}$
. Our argument requires new estimates in order to prove the boundedness of a Cerami sequence.
