Description
ORA-Plus Suspension Vehicle, crafted by Perrigo, is an innovative solution designed to streamline the compounding of oral liquid medications. This aqueous-based, thixotropic liquid serves as a reliable base for creating uniform and stable oral suspensions, accommodating a wide range of active pharmaceutical ingredients (APIs).
Key Features
- Translucent and Milky White: The liquid's unique appearance ensures easy handling and measurement.
- Thixotropic Properties: Enhances the stability and homogeneity of the suspension.
- Unflavored and Unsweetened: Free from sugar, alcohol, and dyes, making it suitable for diverse medicinal needs.
- Bland Taste: Provides versatility in compounding without altering the intended flavor profile.
Formulation Benefits
Buffered to a slightly acidic pH of approximately 4.0 to 4.5, ORA-Plus minimizes the degradation and oxidation of medicinal agents. It includes anti-foam agents to reduce foaming during shaking, ensuring ease of use. The formulation remains stable at both room temperature and under refrigeration, passing the USP preservative effectiveness test <51>.
Compatibility and Versatility
ORA-Plus exhibits excellent compatibility with APIs and retains its suspending properties even when diluted up to 50% with water, flavoring agents, syrups, or alcohol. It is particularly suitable for pediatric, geriatric, and naso-gastric suspensions. Often combined with ORA-Sweet or ORA-Sweet SF, it helps create pleasant-tasting suspensions.
Packaging and Use
Typically packaged in 473 mL amber glass or plastic PET bottles, ORA-Plus is designed for practical use in pharmaceutical settings. Its ability to wet and levigate powdered drugs before achieving the final volume ensures a smooth and uniform suspension.
