Mechanism of action

A transdermal hydrocolloid placebo patch is a non-medicated delivery system used in clinical trials as a control comparator. It mimics the physical characteristics and application method of an active transdermal patch but contains no therapeutic agent, allowing researchers to isolate the pharmacological effects of an investigational drug from placebo effects.
