The study found that medicine degradation under extreme conditions in space is similar to Earth. Sleeping pills, pain killers, alertness and other medications that are regularly supplied to the ISS were tested. “One medication met USP requirements five months after its expiration date. Four on nine drugs were still viable up to eight months after officially expiring. Another three medications met USP guidelines when they were tested three months before their expiry date. A dietary supplement/sleeping aid did not meet USP requirements eleven months after it had expired.” the study reports. This is good news for the future space explorators.
