NASA’s current protocol for storing medications on space missions involves removing pills from their original bottles and placing them into resealable plastic bags to save weight and space. However, a recent evaluation by the Southwest Research Institute (SwRI) suggests this practice may accelerate the breakdown of active pharmaceutical ingredients, potentially reducing the effectiveness of drugs used by astronauts. The findings highlight the need for storage solutions that preserve medication potency during long-duration spaceflights.

Key Takeaways

  • NASA stores medications in resealable plastic bags instead of original packaging to reduce stowage volume.
  • SwRI research indicates that active ingredients degrade faster when kept in bags compared to original containers.
  • The faster degradation could affect medication efficacy for astronauts on extended missions.
  • The study underscores the importance of optimizing pharmaceutical storage for space travel.

Why NASA Changed Medication Packaging

Spacecraft have strict limits on weight and volume, so every item must be carefully packed. NASA decided decades ago to remove medications from their bulky original bottles and put them into lightweight, resealable plastic bags. This approach allowed crews to carry more supplies with less mass. However, the long-term effects on drug stability were not fully examined until the SwRI study.

What the SwRI Evaluation Found

Researchers at SwRI tested several common medications stored under conditions that mimic the space environment, including exposure to radiation and temperature fluctuations. They compared pills kept in original packaging with those placed in plastic bags. The results showed that active pharmaceutical ingredients degraded at a significantly higher rate in the bagged samples. The exact reasons are still under investigation, but possible factors include increased exposure to moisture, oxygen, or physical stress from the bag materials.

Implications for Astronaut Health

If medications lose potency during a mission, astronauts may not receive the intended dose for conditions such as pain, infection, or space motion sickness. On the International Space Station, resupply missions can deliver fresh drugs, but for future deep-space missions to the Moon or Mars, crews will rely on a fixed supply for months or years. Ensuring medication stability is therefore critical for crew safety and mission success.

Potential Solutions and Next Steps

The SwRI team recommends that NASA reconsider its storage protocols. Options include using individual blister packs, improved bag materials with better barrier properties, or returning to original packaging where possible. Further research is needed to identify the precise mechanisms of degradation and to develop storage methods that balance space savings with drug stability. The findings may also benefit terrestrial applications, such as emergency kits or military field packs.

Why does NASA store medications in plastic bags?

NASA uses plastic bags to reduce the weight and volume of medication supplies on spacecraft. Original packaging is often bulky, so repacking pills into lightweight bags saves critical stowage space for other mission essentials.

How much faster do drugs degrade in bags?

The SwRI study reported that active ingredients degraded at a higher rate in bags than in original packaging, but specific percentages were not disclosed in the evaluation summary. The degradation appeared consistent across multiple medication types tested.

Could this affect medications on Earth?

Yes, the findings have broader relevance for any situation where medications are repackaged into non-original containers, such as travel kits or emergency supplies. The study suggests that original packaging may offer better protection against degradation.
