Active-substance-coated medical product, method for its production and its uses

A method for the production of a medical product that can be implanted or introduced into a vascular system of a human or animal organism, having an active substance coating, wherein

• a) one or more separate active substance particles is/are made available, which comprise one or more active substances and one or more polymers, and have a particle diameter less than or equal to 30 μm,
• b) a base body of a medical product is made available, and
• c) said base body from step b) is coated with said active substance particles from step a), in such a manner that said active substance particles can be detached under physiological conditions in the vascular system, in the coated state, but said active substance(s) is/are essentially not released from said detached active substance particles at a pH in the range of 7.3 to 7.5.

An active substance coating for a medical product that can be implanted or introduced into a vascular system of a human or animal organism, wherein

• a) said active substance coating comprises one or more separate active substance particles comprising one or more active substances and one or more polymers, having a particle diameter less than or equal to 30 μm,
• b) said active substance particle(s) can be detached under physiological conditions in the vascular system, from said coating of said medical product, and
• c) said detached active substance particle(s) essentially does/do not release said active substance(s) in a pH range of 7.3-7.5.
