Abstract RU 2244543 C2

FIELD: medicine, pharmacy.

SUBSTANCE: invention relates to a tablet decomposing rapidly in the buccal pocket and comprising a medicinal agent, excipient and saccharide with relatively lower melting point than that of a medicinal agent and excipient.

Except for, invention relates to a method for making tablet decomposing rapidly in buccal pocket and comprising a medicinal agent, excipient and saccharide with relatively lower melting point than that of medicinal agent and excipient. Method involves: (a) the parent components of tablet comprising a medicinal agent, excipient and saccharide with relatively lower melting point that that of a medicinal agent and excipient are pressed under low pressure to provide the required tablet form; (b) pressed product obtained after stage (a) is heated to temperature when saccharide with low melting point is melted; (c) melted product obtained after stage (b) is cooled to temperature when melted saccharide with low melting point is hardened. Invention represents a tablet decomposing rapidly in buccal pocket and having the tablet strength providing its using in tablet-making machines for dosed formulations and giving the possibility for making tablet using common tablet-making machines, and to a method for making tablets.
