Stable pharmaceutical compositions for 2-aza-bicyclo [3.30]-octane-3-carboxylic acid derivatives

摘要

A stable composition of a 2-aza-bicyclo[3.3.0]-octane-3-carboxylic acid derivative and a method for its preparation are described. The stable composition includes an intimate admixture of the derivative and a stabilizing effective amount of a lubricant. The stable composition further includes an external excipient. A method of preparing the stable composition includes forming an intimate admixture of the derivative and a lubricant and then blending the intimate admixture with at least one excipient. Preferably the final blend is transformed into solid unit dosage form.
