Tablet compression is a crucial stage in the production of tablets, where the powder blend or granules are compressed into a solid dosage form. Despite advancements in technology, several issues can arise during the compression and processing stages, impacting the quality and efficiency of the tablet production process. Here are some common problems and their…
Granulation is a critical process in tablet formulation that involves the aggregation of powder particles to form larger, multi-particle entities called granules. This process enhances the flow properties, compressibility, and content uniformity of the powder blend, making it easier to handle and process into tablets. There are two primary methods of granulation: wet granulation and…
Tablets are the most common and widely used dosage form for oral administration of drugs. They are solid, unit-dose forms that are easy to handle, transport, and administer. The formulation of tablets involves several critical steps to ensure their efficacy, stability, and patient compliance. This note provides an in-depth exploration of tablet formulation, including the…
Excipients are inactive substances formulated alongside the active pharmaceutical ingredient (API) of a medication. They serve a variety of roles that are critical to the creation, stability, and functionality of the final pharmaceutical product. While excipients do not exert therapeutic effects themselves, they are essential for the effectiveness, safety, manufacturability, stability, and patient acceptability of…
