The generalized Schrödinger equation and the generalized Klein-Gordon equation are derived by applying the subordination approach to conventional quantum mechanics. The special cases of the fractional Schrödinger equation and the fractional Klein-Gordon equation are adequately introduced. Additionally, the subordination approach is also applied to derive the special case of the generalized Dirac equation for spin 1/2 particles and the directions for future research are discussed. It is evident that according to the subordination approach, the time fractional derivatives in quantum mechanics, including the relativistic one, can be related to the Lévy stable processes in time.
