Introduction

Binder excipients, also known as binders or adhesives, are substances that are added to pharmaceutical formulations to promote the cohesive properties of the mixture. With the liquid surface tension and capillary management to make the powder bonded together. With the mechanical force of compression, so that the distance between the solid powder particles close to the intermolecular force and surface free energy as the main binding force. They help in binding the active pharmaceutical ingredient (API) and other excipients together, providing the necessary strength and stability to the final dosage form.

Subtype of Binder Excipients

Binder excipients can be classified into several categories based on their origin, mechanism of action, and solubility. The following are the commonly used types of binder excipients:

1. Natural Binders:
- Examples: Starch, cellulose derivatives (e.g., hydroxypropyl cellulose), gelatin, acacia gum.
- These binders are derived from natural sources and offer good binding properties and compatibility with various APIs.

2. Synthetic Binders:
- Examples: Polyvinylpyrrolidone (PVP), polyvinyl alcohol (PVA), methylcellulose.
- Synthetic binders are chemically synthesized excipients that exhibit excellent binding characteristics and are widely used in pharmaceutical formulations.

3. Semi-synthetic Binders:
- Examples: Hydroxypropyl methylcellulose (HPMC), ethyl cellulose.
- Semi-synthetic binders are derived from natural polymers but undergo chemical modifications to enhance their binding properties.

4. Inorganic Binders:
- Examples: Bentonite, magnesium aluminum silicate.
- Inorganic binders are minerals or clays that possess binding properties and find applications in specific formulations.

Applications of Pharmaceutical Binder Excipients

1. Tablet Formulations
2. Granulation
3. Controlled-Release Formulations

Conclusion

Binder excipients are a class of substances that enable non-sticky or insufficiently sticky substances to be aggregated or compression molded, often used in dry granulation or tablet compression. Binder excipients provide the necessary binding properties, ensuring the integrity, strength, and functionality of tablets and capsules.
