Usually involving pressure sensitive adhesives (PSAs) function as both effective patch fixation systems and drug matrices, engineered to deliver therapeutically effective amounts of medication across a patient's skin—improving treatment efficiency for targeted diseases while bold: maintaining consistent drug levels in the bloodstream compared to conventional multi-dose treatments, enhancing patient comfort and compliance.

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.
