Syrups are thick, sweet liquid preparations used as a vehicle for oral medications, particularly for those who have difficulty swallowing tablets or capsules.
They often contain a high concentration of sugar or sugar substitutes.
Preparation of syrups:
Step-by-Step Preparation:
Prepare Sugar Solution: Dissolve sugar (sucrose or glucose) in water to form a concentrated syrup base (usually 66% w/w).
Dissolve Active Ingredients: Dissolve the active medicinal ingredient (e.g., cough suppressant, expectorant) in a small volume of water or alcohol.
Combine with Sugar Solution: Mix the medicinal solution with the syrup base.
Add Flavoring Agents: Incorporate flavors like cherry, orange, or vanilla to improve taste.
Preservation: Add preservatives such as sodium benzoate if needed to prevent microbial growth.
Final Filtration: Filter the syrup to remove any particulates.
Packaging: Dispense into sterile bottles, ensuring the neck is wide enough for easy pouring.
