Abstract
The present invention relates to a titratable dosage transdermal delivery system for systemic delivery of a therapeutic agent or drug. The system comprises a plurality of patch units that are connected along one or more borders. The plurality of patch units are divisible into units along the one or more borders having one or more lines of separation. Each patch unit is surrounded by a border. The therapeutic patch has at least a backing layer and a therapeutic agent comprising layer. The dosage of therapeutic agent delivered to a patient is proportional to the number of patch unit applied per treatment. The system enables systemic administration of a titratable dosage of therapeutic agent, adjustable by the patient under the direction of a physician, through the skin or mucosa. Moreover, the invention relates to a method of making the titratable dosage transdermal delivery system. Furthermore, the invention relates to a method of providing a titratable amount of therapeutic agent to a patient using the transdermal delivery system of the invention.
