Tablet Coating Tablet coating is a critical process in pharmaceutical manufacturing that involves applying a layer of coating material to the surface of the tablet. This process can serve various purposes, including protecting the drug substance, masking taste, controlling drug release, and improving the tablet’s appearance. Types of Coating 1. Sugar Coating: A traditional method […]
Tablet formulation is a complex process that involves a series of steps and various types of equipment to produce high-quality tablets. Proper selection and use of equipment and tooling are crucial to ensure the consistency, quality, and efficiency of the tablet manufacturing process. Equipment in Tablet Formulation The main equipment used in tablet formulation can […]
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 […]
Introduction Tablets are solid dosage forms containing one or more active pharmaceutical ingredients (APIs) along with suitable excipients, which are compacted or molded into various shapes and sizes. They are among the most common and convenient forms of medication delivery due to their simplicity, ease of administration, accurate dosage, portability, and stability. Tablets are designed […]
Pre-formulation studies are critical in the pharmaceutical development process as they provide essential information about the physical, chemical, and mechanical properties of a drug substance. This data is used to design and develop stable, effective, and manufacturable dosage forms. Here, we discuss the application of pre-formulation considerations in the development of solid, liquid oral, and […]
The Biopharmaceutics Classification System (BCS) is a scientific framework for classifying drugs based on their solubility and permeability. This system helps predict the drug absorption and bioavailability, which are critical factors in drug development and regulatory approval processes. BCS Classification The BCS classifies drugs into four categories: 1. Class I: High Solubility, High Permeability Characteristics: […]
Understanding the chemical properties of drug substances is critical for predicting their stability, compatibility, and overall behavior during formulation, storage, and administration. Here, we detail key chemical processes including hydrolysis, oxidation, reduction, racemization, and polymerization, along with their significance in pharmaceutical development. 1. Hydrolysis Hydrolysis is a chemical reaction in which water reacts with a […]
