Introduction to Pharmaceutical Excipients
Pharmaceutical excipients are the inactive ingredients in medications, playing a crucial role in drug formulation, stability, and delivery.
Types of Pharmaceutical Excipients
Variety of Excipient Types
Excipients include fillers, binders, disintegrants, and coatings, each serving specific functions in drug manufacturing.
Diverse Coating Options
Coatings can be tailored for taste-masking, extended release, or to protect against stomach acids.
Functions of Pharmaceutical Excipients
Stabilization
Controlled Release
Excipients ensure the stability of active ingredients and prevent potential chemical degradation.
They enable extended or targeted drug release, affecting the drug's pharmacokinetics.
Enhanced Solubility
Some excipients improve a drug's solubility, aiding in its absorption within the body.
Importance of Pharmaceutical Excipients in Drug Formulation
1 Formulation Flexibility
2 Drug Bioavailability
Excipients facilitate the manufacture of tablets, capsules, liquids, and other dosage forms.
They play a vital role in determining the rate and extent to which the active ingredient is absorbed and becomes available at the site of action.
Regulatory Considerations for Pharmaceutical Excipients
Compliance Standards
Excipients must meet strict regulatory specifications to ensure drug safety and efficacy.
Documentation
Thorough documentation of excipient properties and sources is essential for regulatory approval.
Quality Control and Testing of Pharmaceutical Excipients
