Pregelatinized starch, a modified form of native starch, offers unique properties that are highly beneficial in drug formulation. This article explores the scientific underpinnings of pregelatinized starch and its critical applications in the pharmaceutical industry. Knowing the properties of pregelatinized starch is fundamental for effective formulation.

The pregelatinization process involves controlled hydration and thermal treatment of starch granules. This process disrupts the crystalline structure of amylose and amylopectin, the main components of starch. The result is a product that can swell and dissolve in cold water, a stark contrast to native starches that require cooking. This enhanced solubility is key to its effectiveness as a binder and disintegrant.

As a binder, pregelatinized starch forms hydrogen bonds with drug particles and other excipients, creating a strong, cohesive matrix within the tablet. This binding strength is essential for producing tablets that are mechanically stable and resist fracture. Formulators often seek to buy pregelatinized starch for its consistent binding performance, which is crucial for reliable tablet manufacturing.

In its role as a disintegrant, the ability of pregelatinized starch to rapidly absorb water and swell is paramount. When a tablet containing pregelatinized starch is exposed to physiological fluids, the starch granules swell, creating internal pressure that helps to break the tablet apart. This rapid disintegration is vital for ensuring that the API is released promptly for absorption.

Pregelatinized starch also functions effectively as a diluent. Its particle size and flow characteristics contribute to uniform powder distribution in tablet dies, ensuring consistent tablet weight and API content. The price of pregelatinized starch is often favorable for large-scale manufacturing, making it an economical choice for diluent applications.

The consistency and purity of pregelatinized starch are critical for pharmaceutical applications.
