Summary of Makeup Powders in Medicine

In the second part of the chapter on technology related to powders and granules, the speaker discusses various forms of makeup powders used in medicine, emphasizing their applications in oral, external, and injectable forms. Key points include:

Types of Powders:
- oral powders: These can dissolve in water, juice, or food and can work locally (e.g., laxatives) or systemically (e.g., pain relievers like Panadol).
- external powders: These can be used as sprays or powders applied to the skin for various treatments, including antifungal applications.
- injectable powders: These are typically dissolved in a liquid for administration.
Mechanism of Action:
- Local action refers to effects that do not require absorption into the bloodstream, while systemic action indicates that the medication works throughout the body.
- The speaker highlights the importance of particle size for effective absorption, especially in respiratory treatments.
Pharmaceutical Formulation:
- Powders are often preferred for medications that are difficult to formulate into tablets or capsules due to high doses.
- The stability and shelf-life of medications in powder form are discussed, particularly regarding storage conditions to avoid moisture and degradation.
Preparation Techniques:
- Different methods for preparing powders and granules are described, including wet and dry methods, which involve the use of binders and specific drying techniques.
- The speaker explains the significance of maintaining uniform particle sizes for effective dosing and absorption.
Examples of Powders:
- Common pharmaceutical powders mentioned include antacids, laxatives, and various antibiotics, which can come in bulk or divided doses for easier administration.
Dosage and Administration:
- Guidance on how to calculate doses, prepare solutions, and the importance of teaching patients about proper usage and storage of powdered medications is provided.
Granules:
- The discussion also covers granules, which are aggregates of powder particles that improve stability and ease of handling compared to loose powders.
