Which formulation is a dry, ready-to-use mixture with inert carriers, where all particles are larger than dust particles?

• A. Granule (G)
• B. Dust (D)
• C. Aerosol (pressurized can)
• D. Soluble powder (SP)

Answer: (A)

Granules fit this description because they are dry, ready-to-use mixtures created by combining fine powders with inert carriers to form larger, free-flowing particles. The particles are substantially bigger than dust, which helps with handling, dosing accuracy, and reducing airborne dust. The inert carriers (like lactose or starch) provide bulk and flow without adding active material, making the dosage form easy to blend and formulate. In contrast, a dust is just fine particles that can be easily dispersed in air and are not structured as a ready-to-use granular form. An aerosol is a suspension of fine particles in a gas, typically in a pressurized container, and not a dry powder with inert carriers. A soluble powder is designed to dissolve in liquid, not to remain as a dry granulated form with carriers.
