Introduction

Pregelatinized starch is a modified starch that has been processed to dissolve in cold water. It is widely utilized in various industries, including the pharmaceutical sector, for its unique properties that enhance product efficiency. This article focuses on its role and uses within the medical field.

Characteristics of Pregelatinized Starch

Pregelatinized starch provides various functional benefits in pharmaceuticals due to its physical and chemical properties. Some of the essential characteristics include:

• Solubility: It readily dissolves in cold water, which facilitates its use in drug formulations.
• Stability: It maintains stability under varying conditions, crucial for drug preservation.
• Binding capacity: It acts as an effective binder, helping to form tablets without additional adhesives.

Applications in Medicine

Pregelatinized starch is primarily utilized as a binder, disintegrant, and filler in pharmaceutical formulations:

Binder

The adhesive properties of pregelatinized starch make it a popular choice for forming tablets and capsules. It helps ensure the cohesive strength of these forms, with usage rates typically ranging from 5% to 10% of the total formulation mass.

Disintegrant

Pregelatinized starch facilitates the rapid disintegration of tablets in the digestive tract, promoting efficient drug release and absorption. Its effectiveness is evident with concentration levels between 2% and 6% in a standard formulation.

Filler

Serving as a filler, it helps achieve the desired tablet weight and volume. While it dilutes active pharmaceutical ingredients, it maintains uniformity across batches, often used in proportions of up to 50% of the tablet mass for non-potent drugs.
