Component Specifications

Definition
Filler/diluents are pharmacologically inactive excipients used in tablet formulation to provide adequate volume for compression, enhance powder flow during processing, and ensure uniform distribution of active pharmaceutical ingredients (APIs). They serve as bulking agents when API dosage is small, improving tablet weight consistency and mechanical strength while maintaining dissolution characteristics.
Working Principle
Filler/diluents function by occupying space in tablet formulations, creating a compressible matrix that binds APIs and other excipients. They absorb compression forces during tableting, distribute stress evenly, and provide structural integrity through particle bonding mechanisms (mechanical interlocking, plastic deformation, or solid bridges). Their particle size distribution and morphology influence flowability, segregation resistance, and compaction behavior.
Materials
Common materials include microcrystalline cellulose (MCC), lactose monohydrate, dicalcium phosphate, mannitol, starch derivatives (pregelatinized starch), and calcium carbonate. Specifications typically cover particle size distribution (D10/D50/D90), bulk/tapped density, moisture content (<5%), compressibility index (<20%), and microbial limits (<1000 CFU/g).

Frequently Asked Questions

What is the difference between filler and diluent in tablets?

While often used interchangeably, fillers primarily add bulk to achieve practical tablet size, whereas diluents specifically reduce API concentration to ensure accurate dosing. Both serve overlapping functions in flow enhancement and compression.

How do filler properties affect tablet dissolution?

Hydrophilic fillers like lactose accelerate dissolution by promoting water penetration, while hydrophobic materials may slow it. Particle size and solubility also influence disintegration rates and bioavailability.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
