For the first time, we estimate the in-medium mass shift of the two-flavored heavy mesons Bc, Bc^*, Bs, Bs^*, Ds and Ds^* in symmetric nuclear matter. The estimates are made by evaluating the lowest order one-loop self-energies. The enhanced excitations of intermediate state heavy-light quark mesons in symmetric nuclear matter are the origin of their negative mass shift. Our results show that the magnitude of the mass shift for the Bc meson (b c or b c) is larger than those of the ηc (c c) and ηb (b b), different from a naive expectation that it would be in-between of them. While, that of the Bc^* shows the in-between of the J/ψ and Υ. We observe that the lighter vector meson excitation in each meson self-energy gives a dominant contribution for the corresponding meson mass shift, Bc, Bs, and Ds.
