Study Notes
Syrups Overview
- Concentrated aqueous solutions of sugar or sugar substitutes, with or without flavoring agents and medicinal substances.
- Used to mask unpleasant tastes of medications, especially for children and elderly.
- Nonmedicated syrups are used as flavored vehicles (e.g., Cherry syrup, Cocoa syrup, Orange syrup, Raspberry syrup).
- Medicated syrups contain a medicinal agent and are used for therapeutic purposes.
Syrup Components
- Sugar: Typically sucrose, provides sweetness and viscosity.
- Antimicrobial preservatives: Prevent microbial growth.
- Flavorants: Enhance palatability.
- Colorants: Improve aesthetic appeal.
Sucrose- and Non-Sucrose-Based Syrups
- Sucrose is the most common sugar used in syrups.
- Alternatives to sucrose:
- Sorbitol, glycerin, propylene glycol: May be used in whole or in part to replace sucrose.
- Methylcellulose, hydroxy ethylcellulose: Non-glycogenetic substitutes for use in diabetic patients.
- High sucrose concentration limits microbial growth due to water unavailability, enhancing syrup stability.
Syrup Preparation Methods
- Solution by Agitation Without Heat: Preferable for maintaining sucrose stability.
- Addition of Sucrose to a Medicated Liquid or to a Flavored Liquid: Useful for tinctures and fluidextracts.
- Percolation: Involves extracting medicinal components and adding to a sucrose solution.
- Example: Ipecac syrup, prepared by percolation and used as an emetic.
- Syrups are typically stored in tight containers to maintain stability.
Examples of Common Syrups
- Bromhexine syrup: Treats respiratory disorders with excessive mucus.
- Salbutamol syrup: A bronchodilator that eases breathing.
- Samilin, Tussilet: Cough preparations containing different ingredients.
