Question

If the aim of these investigations is to determine the stability of a drug after opening the package, what are the conditions?

• A. \( \text{40°C, 75 RH (0-6 months)} \)
• B. \( \text{Room temp, (0-3 months)} \)
• C. \( \text{Room temp, (0-24 hours)} \)
• D. \( \text{Room temp, (0-4 weeks)} \)

Hint:

Stability testing ensures drug potency and safety over time, preventing degradation due to environmental factors.

Answer 1

The Correct Option is D

Drug stability after package opening is evaluated under room temperature conditions for up to 4 weeks. Factors such as moisture, temperature fluctuations, and exposure to air influence stability. Long-term stability studies under accelerated conditions help determine shelf-life and packaging recommendations.
