Adjuvant pharmacological strategies for the musculoskeletal system during long‐term space missions

British Journal of Clinical Pharmacology, Volume 92, Issue 1, Page 11-23, January 2026.
Abstract Despite 2 h of daily exercise training, muscle wasting and bone loss are still present after 6‐month missions to the international space station. Some crew members lose bone much faster than others. In preparation for missions to the Moon and Mars, space agencies are therefore reviewing their countermeasure portfolios.
