Study Notes

Syrup of Ipecac

Purpose: To induce vomiting in cases of poisoning.
Active ingredient: Emetine, which can lead to toxic buildup with continuous use.
Dosage for children: 15 ml for children aged 1 to 12 years.
Misuse consequence: Does NOT cause dehydration.

Syrups

Source plant for ipecac syrup: Cephaelis ipecacuanha
Nonmedicated syrups purpose: Primarily for flavoring and masking unpleasant tastes.
Cocoa powder syrup: Chocolate syrup
Medicated syrups purpose: To administer medication, especially for children and elderly patients.
Simple syrup base: Sugar (usually sucrose)
Medicated syrup characteristics: Contains a sweetening agent and a drug.
Cherry syrup: Cherry syrup
Why preferred for children/elderly: Easier to swallow and masks unpleasant tastes.
Raspberry syrup: Approximately 30% raspberry juice.
Sucrose function: Sweetening, viscosity, and preservation.
Non-syrup component: Fats
Cellulose derivative role: Adds viscosity, stability, and prevents crystallization.
Sucrose content: Usually 60-80% by weight.
Concentrated sugar resistant to microbial growth: Higher sugar concentration makes water less available for microbial growth.
Antitussive syrup effect: Besides delivering medication, they soothe the throat and suppress coughing.
Sugar substitute for syrups: Sorbitol
Benefit of non-glycogenetic substances: They don't contribute to blood sugar levels.
Excess water in Syrup, NF: Ensures complete dissolution of sucrose and prevents crystallization.
Syrup, NF stability: Sucrose is the main contributor to its stability and resistance to microbial growth.
Sucrose in 100 mL Syrup, NF: 85 grams
Syrup, NF specific gravity: 1.313
Syrup, NF total weight in 100 mL: 131.3g
Preservatives in commercial syrups: To prevent microbial growth during storage.
Dissolving 85g sucrose: Add sufficient purified water to dissolve the sucrose.
Overly saturated syrup: May lead to crystallization during storage.
Boiled purified water advantage: Ensures sterility and prevents microbial contamination.
Agitation without heat: Preferred to avoid caramelization of sugar.
Solid agents in syrup: Must be finely powdered and gradually added to the syrup.
Syrup storage: In tightly closed containers to prevent evaporation and contamination.
Alcohol-soluble constituents in medicated liquid: They're unaffected by the addition of sucrose.
Percolation method: Used to extract active compounds from herbs or other materials.
Undesirable alcohol-soluble components: Use a different extraction method or remove the components before adding sucrose.
Agitation without heat: Time consuming: Takes longer than using heat because the dissolution process is slower.
