TRANSDERMAL SYSTEM FOR THE SIMULTANEOUS DELIVERY OF A NUMBER OF ACTIVE PRINCIPLES

摘要

A novel system for percutaneously delivering at least two active principles, consisting of at least two juxtaposed devices. The system includes (i) a first device containing a mixture of all the active principles in which at least one first active principle (A) is present in an amount enabling the effective therapeutic dose to be delivered, and at least one second active principle (B) is present in an amount smaller than the amount needed to deliver the effective therapeutic dose; and (ii) one or more additional devices each containing a single active principle (B) selected from those in the first device and provided in an amount smaller than the amount needed to deliver the effective therapeutic dose, said additional device(s) being designed to top up the amount of each of the active principles (B) in the system until the effective therapeutic dose is achieved.
