A tablet is a pharmaceutical oral dosage form oral solid dosage , or OSD or solid unit dosage form. Tablets may be defined as the solid unit dosage form of medicament or medicaments with suitable excipients. It comprises a mixture of active substances and excipients, usually in powder form, pressed or compacted from a powder into a solid dose. Tablets are prepared either by molding or by compression. The excipients can include diluents , binders or granulating agents, glidants flow aids and lubricants to ensure efficient tabletting; disintegrants to promote tablet break-up in the digestive tract; sweeteners or flavours to enhance taste; and pigments to make the tablets visually attractive or aid in visual identification of an unknown tablet.
Formulation and Manufacturing of Solid Dosage Forms
Pharmaceutical formulation , in pharmaceutics , is the process in which different chemical substances, including the active drug , are combined to produce a final medicinal product. The word formulation is often used in a way that includes dosage form. Formulation studies involve developing a preparation of the drug which is both stable and acceptable to the patient. For orally administered drugs, this usually involves incorporating the drug into a tablet or a capsule. It is important to make the distinction that a tablet contains a variety of other potentially inert substances apart from the drug itself, and studies have to be carried out to ensure that the encapsulated drug is compatible with these other substances in a way that does not cause harm, whether direct or indirect. Preformulation involves the characterization of a drug's physical, chemical, and mechanical properties in order to choose what other ingredients excipients should be used in the preparation.
Overview DOI: In this chapter, the main processing steps and manufacturing aspects of solid dosage forms are described and the relevant literature is reviewed. Starting with powder feeding, powder blending, granulation dry and wet , and drying the most important. Starting with powder feeding, powder blending, granulation dry and wet , and drying the most important unit operations to make compactable granules are reviewed. As an alternative to granulation, hot-melt extrusion is introduced, together with the various downstream processing choices.
PDF | Amorphous forms of poorly soluble drugs are more frequently developed for the coating of oral solid-dosage forms A loss of spray dried powder compressibility after dry granulation was also observed (Soares et al.
A short summary of this paper. Pharmaceutical formulations have evolved from simple and traditional systems to more modern and complex novel dosage forms. Formulation is a key step in the drug design process, where the active drug is combined with other substances that maximise the therapeutic potential, safety and stability of the final medicinal product.

As solid dosage forms remains the primary option when developing a drug product, it was felt by the guest editors that the need to have a special issue on formulation and manufacturing of solid products could not be overstated. We have seen the science in the field advancing from understanding of organic crystals to handling and processing to amorphous materials and to engineering and manufacturing of fine particles. Understandings at different scales and among different components in a drug product have forged into a new stage of study that calls for deeper exploration that could bridge the molecular dynamics and kinetics with product properties and in vivo performance. This special issue is hoped to showcase a few studies at this frontier. The majority of drugs in the pharmaceutical solid products are present in the crystalline form.
Developing Solid Oral Dosage Forms is intended for pharmaceutical professionals engaged in research and development of oral dosage forms. The objective of this book is to offer updated or current knowledge and skills required for rational oral product design and development.
- Вы обещали мне ключ. Стратмор не остановился. - Мне нужна Цифровая крепость. - настаивал Нуматака.
Танкадо ни за что не доверился бы Хейлу. - Коммандер, - напомнила Сьюзан, - Хейл однажды уже чуть не угробил нас - с Попрыгунчиком. Танкадо имел основания ему верить. Стратмор замялся, не зная, что ответить.
