ABSTRACT:
The selection of: a hydrophobic carbohydrate polymer, e.g. ethyl cellulose; and, generally at least one digestive-difficulty soluble component, i.e. a wax, e.g. carnauba wax, fatty acid material or neutral lipid provides upon dry direct compression a controlled and continuous release matrix for tablets or implants of biologically active agents. Preferred for producing dry direct compressed products is the combination of: a hydrophobic cellulose derivative; a wax, and, a fatty acid material and/or a neutral lipid since it provides upon dry direct compression a controlled and continuous release tablet or implant of improved structurally integrity against externally imposed forces.
