Study Notes
Aqueous Pharmaceutical Preparations
- Syrups and juices are important classes of aqueous pharmaceutical preparations often containing aromatic principles.
- Syrups are viscous, aqueous liquids for oral administration.
- Juice is a liquid extracted from fresh plant parts. The USP includes cherry and raspberry juices.
- Historically, juices frequently served as a base for syrups.
Aromatic Waters
- Aromatic waters are simple formulations, comprising water and volatile solutes.
- They are clear, saturated aqueous solutions of volatile oils or aromatic substances.
- Aromatic waters have low water solubility.
- Examples include cinnamon water, orange flower water, stronger rose water, peppermint water, and camphor water.
Qualities of Pharmaceutical Preparations
- A "elegant" preparation is stable, palatable, and therapeutically effective.
- Stability means no loss in therapeutic activity or undesirable chemical/physical changes over time.
- Shelf life is the time for a drug's level to degrade to 90% of its labeled potency at room temperature (25°C).
- Factors affecting stability: environmental (microbial contamination, light, oxygen, humidity, temperature), chemical (hydrolytic degradation, autoxidation), and physical (precipitation, color/odor/viscosity changes).
- Palatability means a pleasant taste. Factors affecting flavor selection include intended age group, preparation color, taste to be masked, and dosage form.
Therapeutic Efficacy
- Therapeutic effectiveness is measured by a preparation's ability to quickly release medicinal agents.
- A preparation can be stable and palatable but therapeutically worthless.
Uses of Aromatic Waters
- Aromatic waters provide a flavored medium for water-soluble drugs, emulsions, and suspensions.
- They generally aren't therapeutically potent due to low active ingredient content.
- Examples:
- Peppermint water: carminative, vehicle
- Chloroform water: expectorant (5-15 mL dose)
- Rose water: perfume
- Hamamelis water: astringent, rub, aftershave (12.5% v/v and 0.01% w/v naphazoline for eye redness)
- Camphor water: refreshing for eyes, rubefacient, cough suppressant.
Preparation of Aromatic Waters
- Most waters are prepared by distillation, although other methods are often more practical/cost-effective.
- Some (e.g., stronger rose water, orange flower water, Hamamelis water) must be prepared by distillation directly from fresh plant material.
- Note: The distillation method involves placing the plant material in a still with purified water, then carefully distilling most of the water.
