Overdrying of granules in fluid bed dryers can lead to several issues, including reduced granule compressibility, increased friability, and potential API degradation. These problems compromise tablet quality, reduce yields, and can affect compliance with regulatory standards. Preventing overdrying ensures granules retain their desired moisture levels and functional properties.

In pharmaceutical tablet formulation, fillers (also known as excipients or diluents) are an essential component used to add bulk to tablets containing small amounts of active pharmaceutical ingredients (APIs). Proper selection of fillers is crucial, as they influence the tablet’s compactibility, disintegration, dissolution, and overall performance. One of the most common challenges in tablet formulation is selecting the right filler to ensure that the final product has the desired characteristics such as mechanical strength, uniformity, and bioavailability. Addressing these challenges through the careful selection of fillers can improve both production efficiency and product quality.

Granule caking occurs when wet granules clump together excessively during the wet granulation process in high-shear mixers, resulting in uneven particle sizes and reduced flowability. This problem can compromise tablet uniformity, compressibility, and overall product quality. Understanding and addressing the root causes of caking is crucial for optimizing the granulation process.

The formulation of immediate release (IR) tablets is a critical aspect of pharmaceutical dosage form development. These tablets are designed to release their active pharmaceutical ingredients (APIs) rapidly upon ingestion, ensuring fast onset of action. However, formulating these tablets presents unique challenges that must be addressed to ensure consistency, quality, and efficacy of the final product. These challenges can arise in various stages of production, from formulation and manufacturing to quality control, validation, and stability testing. Addressing these challenges effectively is key to maintaining a successful IR tablet production process.

Wet granulation is a process of agglomerating powder particles using a liquid binder to create granules with improved flowability, compressibility, and uniformity. It ensures consistent tablet quality by addressing challenges like segregation and uneven distribution of active pharmaceutical ingredients (APIs). Optimizing wet granulation is critical for achieving uniform tablet blends and maintaining product efficacy.

Mottling refers to the uneven distribution of color on the surface of film-coated tablets, resulting in a patchy or blotchy appearance. This defect is often caused by improper pigment dispersion, formulation issues, or process inconsistencies. Mottling affects the aesthetic quality of tablets and can raise concerns about product quality among consumers and regulators.
