Extrusion / Spheronization

Capsugel offers a drug delivery technology extrusioj provide oral delivery with full enteric protection and rapid release in the upper gastrointestinal GI tract without the use of coatings.

The process consists of five operations. This dough then pressed through an extruder. Even if the ball-shaped extrudate is imperfect, the evenness of the surface still creates good conditions for subsequent coating.

In the pharmaceutical industry, pellets of medium particle sizes from to 2, micrometers are used for most applications. Just the way you need it. Join us for the multiparticulates webinar, where key considerations in designing multiparticulate formulations and processing will be discussed with representative case studies. Our Mini-tablets are a popular finished dosage form presentation and offers the benefits of multiparticulates while using established tableting technology. The process consists of four process extrusioj The exhrusion spheres are dried in a fluid bed dryer and particle size is selected by sieve cuts.

Agglomeration through extrusion and spheronization is one of the oldest techniques for manufacturing pellets.

It is useful for making dense granules for controlled-release solid oral dosage forms with a minimum amount of excipients, as well as multiparticulates used for immediate, modified, or sustained-release.

Extrusion & Spheronization Pharmaceutical Technology

Capsugel Dosage Form Solutions is offering a webinar that provides an overview of current taste masking approaches, with emphasis on two growing technology options. By Product Development Site. The wet extrudate is added to an LCI Marumerizer QJT spheronizer equipped with a high speed spinning plate which forms uniform spheres from the extrudate “rope”. Read more about it here! Capsugel has extensive experience and capabilities in optimizing pediatric and multiparticulate formulations.

Capsugel is well versed in using drug layering and modified-release coat layering to achieve a range of dissolution profiles in multiparticulate format.

The final drying ensures the pellet hardness. The technology chosen is dependent upon multiple active ingredient and formulation criteria, e. Register for An Account Already a member?

The diameter of the openings in the extrusion plate or extrusion basket determines the strength apheronization the elongated extrusion threads that result. The ratio of liquid to solid material together with the estrusion of the extruder holes significantly determines the quality of the extrudates.

For many pharmaceutical applications, extruded pellets are achieved in suitable quality if a sufficient portion of microcrystalline cellulose is added.

The wet spheronizarion is added into an LCI Multigranulator MG 55 where it is forced through a specific screen to form cylindrical extrudates using either dome, radial or axial extrusion for process optimization.

The coated spheres may be used for encapsulation, compression, or direct packaging into sachets or pouches for dosing. Moistening the powder mixture, forming cylinder-shaped agglomerate through extrusion, breaking and rounding the extrudate to round pellets through spheronization, and drying the finished product.

The spheres may undergo additional processing steps to apply functional or cosmetic coatings using fluid bed processing with a Wurster insert.
