Study Notes
Effervescent Solution (Potion Riviere)
- A mixture of a recently prepared salt (from combining an acid and a carbonate/bicarbonate)
- Produced at the time of dispensing
- Mixture is saturated with carbon dioxide (CO2)
- Chemical equation: Acid + Bicarbonate/Carbonate → CO2 + Salt + H2O
Alkaline and Acid Solutions
- Prescriptions for both alkaline and acid solutions are provided
- Ingredients and quantities for each solution are detailed (e.g., NaHCO3, citric acid, simple syrup, syrup of lemon, water)
- Each solution is measured (e.g., 0.35 g NaHCO3, 2 ml simple syrup)
- Instructions to mix both solutions directly before use are given
Calculations (General)
- F= 2/1
- Amount of vehicle = 30-4=26 ml (example)
Procedure (General)
- Instructions for specific preparations
- Dissolve ingredients into a vehicle (usually water) in a specific order.
- Top up to a final volume
- Pour into separate containers
- Label containers
Infusion Senna
- Uses Senna leaves for laxative use
- Senna leaves: 5g
- Boiling water: 100ml (to make 100ml of finished solution)
- Finished solution volume: 30ml
- Calculations for F = 0.3, 40% excess water, total volume: 42 ml
- Procedure details: soak, filter, and don't fill to final volume
Black Draught
- Liquid medication intended for oral administration
- Prescribed in large doses
- Ingredients and quantities are detailed (e.g., MgSO4, tr Cardomum, liquid extract of liquorice, aromatic spirit NH3, infusion senna)
- Instructions for preparing the solution are provided
Decoction of Ammi Visnaga
- Uses Ammi visnaga for a preparation
- Ammi visnaga: 5g
- Cold water: 100 ml
- Finished solution volume: 30ml
- Calculation F=30/100=0.3, 40% excess water, total volume: 42 ml
- Procedure details: crushing plant, soaking, boiling for 10 minutes, filter, adjust to final volume
Decoction (General)
- A process for extracting water-soluble, heat-stable ingredients from crude drugs by boiling them in water
Practical Work (General)
- Prescriptions and quantities for different solutions are detailed for different practical components (e.g., K citrate, Tr. Hyoscyamin, Dec. Ammi visnaga)
- Instructions for preparing solutions
- Calculations for final volumes are provided (e.g., F = 1, Decoction = 30-2=28ml)
Tools
- Materials for preparing the different solutions (e.g., watch glass, spatulas, beakers, cylinders, funnel, cotton)
- Measuring devices provided (e.g., graduated pipettes and droppers).
Uses (General)
- A list of specific uses for different ingredients in the various preparations (e.g., laxative, antispasmodic)
Comparison Between Infusion and Decoction
