Which term describes dry solids that yield solutions meeting injection requirements when reconstituted with an appropriate vehicle?

• A. Powder for Injection
• B. Powder for Injectable Suspension
• C. Injectable Suspension
• D. Injectable Emulsion

Answer: (A)

The key idea is dry solids that are intended to be dissolved to form a true solution for injection. When a manufacturer provides a drug as a powder that must be reconstituted with a sterile vehicle (like sterile water for injection or normal saline) to yield a clear, homogeneous solution suitable for parenteral administration, this is described as a powder for injection. It emphasizes solubility upon reconstitution rather than dispersion. The other forms describe products that, after reconstitution, do not form a true solution. A powder for injectable suspension is designed to yield a suspension, where drug particles remain dispersed but not dissolved. An injectable suspension or an injectable emulsion refers to final forms that involve dispersed particles or droplets, not a dissolving solid-to-solution transformation.
