    Study Notes

    Pharmacognosy

    Adjuvants

    • Substances that enhance or modify the effect of a drug or other pharmacologically active substance
    • Examples: preservatives, antioxidants, and pH adjusters
    • Functions:
      • Enhance bioavailability
      • Improve stability
      • Modify release rates
      • Enhance patient compliance

    Excipients

    • Inactive substances used in pharmaceutical formulations
    • Functions:
      • Fillers (e.g., lactose, starch)
      • Binders (e.g., starch, gum arabic)
      • Lubricants (e.g., magnesium stearate)
      • Glidants (e.g., silicon dioxide)
      • Coatings (e.g., shellac, wax)

    Drug Delivery Systems

    • Methods or formulations that control the release and absorption of a drug
    • Examples:
      • Controlled-release tablets or capsules
      • Transdermal patches
      • Liposomes
      • Nanoparticles
    • Goals:
      • Improve bioavailability
      • Reduce side effects
      • Enhance patient compliance
      • Target specific tissues or cells

    Pharmaceutical Packaging

    • Materials and containers used to protect and preserve pharmaceutical products
    • Functions:
      • Protect from light, moisture, and contamination
      • Maintain potency and stability
      • Ensure product identity and authenticity
      • Provide patient instructions and warnings
    • Types:
      • Glass or plastic bottles
      • Blister packs
      • Ampoules
      • Prefilled syringes

    Cosmetic Formulation

    • Combination of ingredients to create a cosmetic product
    • Key components:
      • Active ingredients (e.g., retinol, vitamin C)
      • Inactive ingredients (e.g., emollients, thickeners)
      • Preservatives (e.g., parabens, phenoxyethanol)
      • pH adjusters and buffers
    • Goals:
      • Enhance appearance and skin health
      • Provide moisturizing and protective effects
      • Minimize irritation and allergic reactions
