Study Notes
SKIN - Functions
- First line of defense against disease-causing pathogens
- Protection
TOPICAL AGENTS - SKIN
- Compounds applied to body surfaces.
- Effects are localized (at the application site) or systemic (affecting multiple organs).
- Sheetmasks are considered topical.
- Intradermal agents are not topical.
- Mouthwash is topical.
PROTECTIVES
- Chemically inert
- Insoluble
- Prevent skin irritation
- Difficult to remove
- Applied as dusting powders, suspensions, or ointments.
PROTECTIVE PROPERTIES - EXAMPLES
- Talc: Native hydrous magnesium silicate. Used as a filtering agent, dusting powder.
- Aluminum Oxide: Prevents irritation, protects skin from digestive action of intestinal fluids.
- Calamine: Primary ingredient is zinc oxide, pink color is from ferric oxides, can be phenolated (1%). Used in open wounds/fluid weeping wounds.
- Zinc Stearate: Not wetted by moisture, does not form crusty patches.
- Titanium Dioxide: Can be used instead of talc.
- Aluminum: Reflects UV radiation.
- Silicon Polymer: For wounds discharging large amounts of fluids.
- Simeticone: Used for gastrointestinal issues.
ANTIMICROBIALS
- Antiseptics: Agents that kill or inhibit the growth of microorganisms on living tissue.
- Disinfectants: Agents that destroy microorganisms on non-living objects.
- Sterilization: Completely free of microorganisms.
- Compounds: Examples: Iodine, chlorine, potassium permanganate, hydrogen peroxide. Various mechanisms: oxidative action, reducing groups.
- Halogenation: Use of hypochlorite.
- Protein Precipitation: Examples: Silver, mercury, sulfur. Complexation with proteins can destroy microbes.
