ExMC Ground-Based Space Radiation Analog Pilot Drug Stability Studay: Final Data Review

Uncertainty regarding space radiation effects on medication degradation and potency remains high, though early data suggest that space radiation may affect the potency and quality of some pharmaceuticals. In the absence of empirical spaceflight measurements to characterize this risk area for long-duration planetary missions, high-fidelity ground-based targeted radiation analogs could provide valuable insights. The NASA Human Research Program's (HRP) Exploration Medical Capability (ExMC) Element conducted a pilot study to characterize the chemical stability of four selected medications exposed to rapid switching, mixed-species simulated galactic cosmic radiation (GCR) beams at the NASA Space Radiation Laboratory (NSRL), at Brookhaven National Laboratory (BNL). The research objective was to compare the effects of simulated GCR beam exposures on drug stability to those previously observed following spaceflight.
