Abstract
The described therapeutic compositions with controlled release of medicaments comprise a medicament loaded onto particles of a crosslinked non-ionic polymer insoluble but swellable in water, using either swelling with solutions of the medicament or high-energy co-grinding methods. The medicament-loaded particles are coated with a polymers film able to control medicament release, to obtain a prolonged release of the medicament (even exceeding 24 hours) while maintaining high bioavailability.
