1. Inertness: Pharmaceutical excipients should be chemically inert, meaning they do not react with the active pharmaceutical ingredient (API) or other excipients present in the formulation. This ensures stability and prevents any unwanted interactions that could affect the efficacy or safety of the drug.
2. Compatibility: Excipients should be compatible with the API and other excipients in the formulation. They should not cause any physical or chemical interactions that could lead to degradation or alteration of the drug's properties.
3. Safety: Excipients should be safe for consumption and should not pose any health risks to patients. They should be non-toxic, non-irritating, and non-allergenic. Regulatory authorities have established guidelines and specifications for excipients to ensure their safety.
4. Stability: Excipients should be stable under various storage conditions, including temperature, humidity, and light exposure. They should not undergo degradation or change in physical or chemical properties over time, as this could affect the drug's efficacy and shelf life.
5. Solubility: Excipients may need to enhance the solubility of poorly soluble APIs to improve their bioavailability. They should have appropriate solubility characteristics to aid in drug dissolution and absorption.
6. Flowability: Excipients used in solid dosage forms, such as tablets or capsules, should have good flow properties to ensure uniform mixing and consistent dosing during manufacturing processes.
7. Taste and odor masking: Some excipients are used to mask the unpleasant taste or odor of certain drugs, especially in oral formulations. They should effectively mask these sensory attributes without interfering with the drug's therapeutic activity.
8. Controlled release: Certain excipients can be used to control the release of the drug from the dosage form, allowing for sustained or targeted drug delivery. These excipients should have the desired release characteristics and should not affect the drug's stability or efficacy.
9. Appearance: Excipients should have a desirable appearance, such as being colorless, odorless, and free from visible impurities. This ensures the overall quality and aesthetics of the final pharmaceutical product.
10. Regulatory compliance: Excipients should comply with regulatory requirements and guidelines set by authorities such as the United States Pharmacopeia (USP), European Pharmacopoeia (EP), or other relevant regulatory bodies. They should meet specific quality standards and undergo appropriate testing to ensure their suitability for use in pharmaceutical formulations.
