Question

A dry powder suspension for reconstitution is prepared mainly to _______

• A. Improve taste
• B. Increase shelf life
• C. Increase viscosity
• D. Improve color

Hint:

Dry powder suspensions are prepared for drugs that are unstable in water, so they help to increase shelf life.

Answer 1

The Correct Option is B

Concept:
Dry powder for oral suspension is a dosage form in which the drug is supplied in dry powder form and water is added before use.

Step 1: Understanding dry powder suspension.
Some drugs are unstable in aqueous medium for a long time. If they are stored as liquid suspension, they may undergo degradation.

Step 2: Why dry form is used.
When the drug is kept in dry powder form, the possibility of hydrolysis and microbial growth is reduced. This improves the stability of the preparation.

Step 3: Reconstitution before use.
The patient or pharmacist adds water before administration. After reconstitution, the product is used within a limited time.

Step 4: Final answer.
The main purpose of preparing dry powder suspension for reconstitution is to increase shelf life. \[ \boxed{\text{Increase shelf life}} \]
