Mechanism of action

Vehicle placebos are used in clinical research as control comparators to isolate the true pharmacological effects of an active drug from placebo effects and natural disease progression. This particular formulation is a nasal spray vehicle—likely containing saline, buffering agents, and preservatives—without any therapeutic agent, allowing researchers to measure the efficacy of the actual drug being tested.
