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
