Effect of common excipients on intestinal drug absorption in Wistar rats
The aim of the present paper is to study the effect of common excipients on the permeability of atenolol (as drug absorbed mainly by passive diffusion) and rhodamine (as P-Glycoprotein substrate). Apparent permeability was measured by in situ perfusion method in Wistar rats using the Closed loop…

Temperature: an overlooked factor in tablet disintegration
Disintegration is the first event in the bioavailability cascade after the ingestion of immediate release tablets. Although the influence of various physico-chemical parameters of media on tablet disintegration has been investigated in depth, the role of temperature has received much less attention.…

Metformin Hydrochloride- and Glyburide-Containing Orally Disintegrating Tablets
Diabetes is characterized by chronic hyperglycemia. Although metformin hydrochloride (MHCl)- and glyburide (GLB)-containing conventional tablets are available in the market and used to treat diabetes, orally disintegrating tablets (ODTs) containing the combination of these drugs are not commercially…

Compaction behavior of isomalt after roll compaction
Isomalt is a polyol derived from sucrose. Advantages of this excipient are its sweet taste, which is supposed to allow taste masking, the low glycemic and insulinemic response (Petzoldt, 1982), and the ability to be compacted directly. With regard to infantile patients, also the lack of…

Development and Evaluation of an In-line and On-line Monitoring System for Granule Size…
Roll compaction/dry granulation is established in manufacturing of solid oral dosage forms and, within the context of continuous manufacturing, it has sparked interest as material is fed, processed, and ejected continuously while also providing large possible throughputs. However, this amount of…
