Study Notes
Solutions and Dosage Forms
- Solute dissolves in the solvent to form a solution.
- Solutions are suitable for geriatrics and pediatrics due to easy administration and precise dosing.
- A system with solute dissolved in a suitable solvent is referred to as a solution or mixture.
- Topical applications for skin or body cavities typically involve aqueous or non-aqueous solutions.
- The solvent is the component that dissolves the solute in a solution.
- A solution with uniform distribution of the medicament is called a homogeneous solution.
Disadvantages and Considerations
- A disadvantage of solution dosage forms compared to solid forms is generally lower stability and potential for a shorter shelf-life.
- Sterile water for injection is suitable for formulating parenteral solutions.
- Potable water is freshly boiled and cooled before use to eliminate microbial contamination.
- Water can dissolve ionic and polar compounds, making it an effective solvent in pharmaceuticals.
- Water for injection is primarily used due to its sterility and lack of additives, ensuring safety in parenteral formulations.
Special Populations and Stability
- Liquids provide a suitable dosage form for geriatrics and pediatrics because they are easier to swallow and adjust in dosage.
- The primary disadvantage of liquid dosage forms is their chemical instability, which can lead to degradation or reduced effectiveness.
- Preservatives are added to certain liquid solutions to prevent microbial growth and extend shelf-life.
