Usually involving pressure sensitive adhesives (PSAs) as a patch fixation system and/or drug matrix, drug delivery patches are designed to deliver a therapeutically effective amount of drug across a patient’s skin to efficiently treat targeted diseases.
These patches typically require drug and formulation dependent properties, such as:
• Good adhesion profile for the application period
• Adequate drug loading
• Manageable patch size
• Sufficient skin flux of the drug
• Sufficient control of the delivery rate to avoid overdosing
• Depletion rate over the designed dosage period
Our teams work with customers to develop customized Liveo™ BIO-PSA adhesive solutions for their specific needs and provide the regulatory and toxicology support appropriate to the applications.
