Practical Significance
Simple syrup is a multipurpose used liquid oral formulation, like sweetening agent, vehicle, antioxidant, preservative, etc. Through this practical student will be able to learn about definition, advantages, types, composition, method of preparation, evaluation, storage, use and labelling requirements of syrup.
Relevant Theoretical Background
Syrup I.P. is a sweet, viscous, concentrated or nearly saturated aqueous solution of sucrose containing 66.7%w/w of sugar having specific gravity 1.31. It imparts high osmotic pressure. This osmotic pressure prevents the growth of bacteria, fungus and molds. The syrup is further classified into Simple flavored syrup and Medicated syrup. Simple flavored syrup does not contain any medicament but contains flavored substances whereas Medicated syrup contains medicinal substances. Simple syrup IP is prepared by hot method while simple syrup USP is prepared by cold method.
Requirements
a. Apparatus: 100 ml beaker, Glass rod, 100 ml measuring cylinder, narrow mouth glass bottle.
b. Equipment: Calibrated weighing balance.
c. Chemicals: Sucrose I.P., Purified water
Factor Calculation
Factor = Required Quantity/ Given Quantity
Formulation Table
Procedure
- Weigh the required quantity of sucrose and mix with purified water.
- Heat in a water bath until it dissolves with occasional stirring.
- Add sufficient purified water to make up the weight.
- Filter if necessary and adjust the weight to 20 ml.
- Evaluate formulation as per evaluation parameters and note the observations.
- Transfer into the container, attach a prepared label and submit.
Use of Preparation
Pharmaceutical Aid
Direction
Use as directed
Precautions
a. Avoid overheating otherwise sucrose will be charred and become black.
b. Cool the preparation before transferring to the container.
Storage
It should be stored in a well closed container and kept in a cool place preferably below 250C
Result
__ml of Simple syrup IP is prepared, evaluated and submitted in a ___________container with special instructions as_______________________.

FAQ’s
Define syrup.
A syrup is a concentrated, viscous solution of sugar in water or other aqueous liquids, often used as a vehicle for medicinal substances or as a sweetener in culinary preparations. Syrups can be medicated (containing active pharmaceutical ingredients) or non-medicated (for flavoring).
What are the two types of syrups?
Medicated Syrups: These contain medicinal substances in a sugar solution, making the medicine more palatable and easier to administer.
Flavored Syrups (Non-Medicated): These are used as flavoring agents in food and beverages, such as maple syrup, corn syrup, or flavored syrups for coffee and desserts.
What are the advantages of using syrup as a dosage form?
Palatability: Syrups have a sweet taste that masks the unpleasant taste of some drugs.
Ease of Administration: Liquid forms are easier to swallow, especially for children, the elderly, or patients with swallowing difficulties.
Flexibility in Dosing: Syrups allow for precise and flexible dosage adjustment, which can be beneficial for pediatric and geriatric patients.
Stability: Syrups can maintain the stability of certain drugs that might degrade in solid form.
Why is there no need to add preservatives in syrup?
Syrups have a high concentration of sugar (typically around 65% w/v), which acts as a natural preservative. This high sugar content creates an osmotic effect that inhibits the growth of microorganisms by drawing water out of the cells, thereby preventing microbial contamination and spoilage.
What are the methods of preparation of syrup?
Simple Solution Method: Dissolving sugar directly in water or a medicated solution by applying gentle heat.
Percolation Method: Water or solvent is passed through a bed of sugar or the medicinal component, extracting it into the syrup.
Agitation Without Heat: In this method, sugar is dissolved in water with constant stirring without the application of heat, which is useful for heat-sensitive ingredients.
Addition of Medicating Agent to Prepared Syrup: This involves preparing a base syrup first and then adding a medicating agent to it.
