NAPLEX (North American Pharmacist Licensure Examination) Practice Exam

What is the primary purpose of pulverization by intervention?

1. To dissolve insoluble drugs

2. To create a solution

3. To produce finer particles from crystalline powders

4. To mix two liquids

The correct answer is: To produce finer particles from crystalline powders

Pulverization by intervention is primarily used to produce finer particles from crystalline powders. It involves using physical or chemical methods to break down larger particles into smaller ones. This process is commonly used in the pharmaceutical industry to increase the surface area of drugs, making them easier to dissolve and increasing their bioavailability. Option A is incorrect because pulverization by intervention does not involve dissolving insoluble drugs. Option B is incorrect because the primary purpose of pulverization by intervention is not to create a solution, but to create smaller particles. Option D is incorrect because pulverization by intervention is not used to mix two liquids, but rather to break down solid particles.
