The present invention relates to a film-coated tablet containing drospirenone active agent, comprising a tablet core coated with a film-forming polymer layer with improved resistance against atmospheric humidity. The tablet core is obtainable by a process which comprises dissolving drospirenone in ethanol, then dripping the solution obtained onto the surface of the fluid bed in a fluidizing equipment without spraying pressure while controlling the temperature of the product obtained and removing the solvent molecules from the wet material by a hot airflow.
