A process for making, on regions (12) of the surface of a stent (1), a deposit of an active substance (M), comprises: providing the active substance (M) in at least one form chosen between a powder and a paste; and depositing the active substance (M) on said regions (12) of the surface of the stent (1). Preferably, the active substance (M) substantially consists of FK506, such as FK506 in the form of a powder with a grain size smaller than 15 micron or a paste with a base of FK506 with a viscosity not lower than 100,000 - 120,000 cps.
