In this manuscript, we consider stochastic expressions of the parametrix method for solutions of -dimensional stochastic differential equations (SDEs) with drift coefficients which belong to . We prove the existence and Hölder continuity of probability density functions for distributions of solutions at fixed points and obtain an explicit expansion via (stochastic) parametrix methods. We also obtain Gaussian type upper and lower bounds for these probability density functions.
