Question

1. : breaking a part of a tablet into smaller pieces.
2. colloids : suspended formulation with particle size up to a hundred times smaller than a suspension.
3. : injection technique for medications that stain the skin.
4. : the cellular lining of the nose.
5. : device used to convert liquid to a spray.
6. : a device that contains a drug that is vaporized by inhalation.
7. : ease of flow when a suspension is injected into a patient.
8. : aerosols that use special metering valves to deliver a fixed - dose when the aerosol is actuated.
9. : the absorption of drugs through the skin, often for a systemic effect.

Explanation:

1. This is called comminution, which involves breaking a tablet into smaller pieces.
2. Colloids are suspended formulations with particle - size much smaller than suspensions.
3. Z - track injection is used for medications that stain the skin.
4. The nasal mucosa is the cellular lining of the nose.
5. An atomizer is a device used to convert liquid to a spray.
6. An inhaler is a device that contains a drug vaporized by inhalation.
7. Injectability refers to the ease of flow when a suspension is injected into a patient.
8. Metered - dose aerosols use special metering valves to deliver a fixed dose when actuated.
9. Transdermal drug absorption is the absorption of drugs through the skin for a systemic effect.
