The aim of the present study was to formulate new variants synthetic and animal-source bone materials coated with different biopolymers, containing antibiotics (ampicillin oxacillin) alendronate drugs. Validation consists in establishing mixtures that do not interactions between components. These should act as a drug delivery system alongside base. Natural polymers such chitosan, alginate, kappa-carrageenan have been shown be optimal for due their intrinsic biocompatibility. Binary, ternary,...
