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.
